Introduction & Background

Weight gain occurs when the body consistently consumes more calories than it burns, leading to the storage of excess fat. Over time, weight gain can have significant effects on metabolism, the process through which the body converts food into energy. Metabolism is often categorized into two phases: catabolism (breaking down food for energy) and anabolism (building and repairing tissues). A person’s metabolic rate (the speed at which they burn calories) plays a critical role in regulating weight and overall health.

However, when individuals gain weight, especially in the form of excess fat, it can alter the body’s metabolic function. Changes in hormones, insulin sensitivity, and fat storage mechanisms can all be influenced by weight gain. Understanding how weight gain impacts metabolism is essential for formulating effective prevention and treatment strategies for obesity and related metabolic disorders like diabetes and cardiovascular disease.

Causes of Weight Gain and Its Impact on Metabolism

Weight gain is the result of several contributing factors, which often work in combination. These causes can be broadly classified into lifestyle factors, genetic influences, and environmental triggers:

1. Poor Diet: High intake of calories, particularly from processed foods, sugars, and fats, can overwhelm the body’s ability to burn them off, leading to fat storage. An imbalance between caloric intake and expenditure results in weight gain.
2. Lack of Physical Activity: Sedentary lifestyles are a major contributor to weight gain. Physical activity not only helps burn calories but also keeps the metabolism functioning efficiently.
3. Genetic Factors: Some individuals may be genetically predisposed to store fat more efficiently or have a slower metabolism. Genetic predisposition can affect the body’s ability to regulate appetite and energy expenditure.
4. Hormonal Changes: Hormones like insulin, cortisol, and thyroid hormones play a critical role in regulating metabolism. Weight gain can disrupt the delicate balance of these hormones, which may lead to more fat storage.
5. Medical Conditions: Conditions such as hypothyroidism, polycystic ovary syndrome (PCOS), and insulin resistance can slow down metabolism and cause weight gain.
6. Medications: Certain drugs, including antidepressants, corticosteroids, and insulin, may lead to weight gain as a side effect by altering the body’s metabolic processes.

Indications of Weight Gain and Metabolic Disruption

Weight gain becomes concerning when it reaches a point where it negatively impacts metabolism and overall health. Key indicators of metabolic disruption include:

1. Increased Body Fat Percentage: The accumulation of fat around the abdomen, known as visceral fat, is particularly harmful as it can affect hormone regulation and contribute to metabolic disorders.
2. Slowed Energy Levels: A noticeable drop in energy levels despite adequate rest could indicate a slower metabolism, which is often a result of excessive weight gain.
3. Difficulty Losing Weight: Individuals may find it increasingly difficult to shed excess pounds, even with dietary changes and increased exercise, as the body adapts to weight gain and metabolic efficiency decreases.
4. Increased Appetite: The body may signal the brain to consume more food, which can contribute to a cycle of overeating and continued weight gain.
5. Changes in Blood Sugar and Insulin Resistance: Weight gain, particularly abdominal fat, is linked to insulin resistance, a condition in which the body becomes less responsive to insulin. This can lead to higher blood sugar levels and, over time, to type 2 diabetes.

Symptoms of Metabolic Dysfunction Due to Weight Gain

When metabolism is disrupted due to weight gain, individuals may experience several symptoms that signal an imbalance in metabolic function:

1. Frequent Hunger and Cravings: Insulin resistance and hormonal imbalances can lead to uncontrollable hunger and cravings, particularly for high-sugar or high-fat foods.
2. Inability to Lose Weight: Despite efforts to reduce calorie intake or increase physical activity, weight loss becomes more difficult, or weight may continue to rise.
3. Fatigue and Lethargy: Slower metabolism means the body has less energy available from food, leading to feelings of tiredness and sluggishness.
4. Mood Swings and Irritability: Hormonal fluctuations due to weight gain can affect brain chemicals that regulate mood, potentially leading to irritability, anxiety, or depression.
5. Increased Sweating and Heat Sensitivity: Disrupted metabolism may lead to abnormal sweating or discomfort in high temperatures as the body’s thermoregulation mechanism is affected.

Prevention Strategies for Weight Gain and Metabolic Disruption

Preventing weight gain and maintaining a healthy metabolism requires a combination of lifestyle modifications:

1. Balanced Diet: Prioritizing nutrient-dense, whole foods such as fruits, vegetables, lean proteins, and whole grains can help regulate calorie intake while maintaining metabolic efficiency.
2. Regular Physical Activity: Engaging in regular exercise, including both aerobic and strength training activities, can help regulate weight, improve insulin sensitivity, and enhance metabolic rate.
3. Stress Management: High levels of chronic stress can increase cortisol levels, contributing to weight gain and metabolic dysfunction. Techniques like meditation, yoga, or mindfulness can be helpful.
4. Adequate Sleep: Consistently getting 7–9 hours of sleep per night is crucial for maintaining hormonal balance and supporting metabolic processes.
5. Hydration: Drinking enough water aids in metabolism by supporting digestion and fat-burning processes.

Myths and Facts About Weight Gain and Metabolism

Myth 1: “Metabolism is solely determined by genetics.”
Fact: While genetics plays a role in metabolism, lifestyle factors such as diet and exercise have a significant impact on metabolic function.

Myth 2: “Eating at night causes weight gain.”
Fact: The timing of eating is less important than the total calorie intake. Eating late at night does not inherently cause weight gain unless it contributes to a calorie surplus.

Myth 3: “Metabolism slows down drastically with age.”
Fact: While metabolism does tend to decrease slightly with age, maintaining physical activity and a healthy diet can minimize this decline.

Myth 4: “Drinking water can significantly boost metabolism.”
Fact: Drinking water may slightly increase metabolism, but it’s not a magic solution for weight loss. It’s important to focus on overall lifestyle changes.

Introduction & Background:

Weight gain is a natural process that often occurs as people age, although it is not an inevitable outcome for everyone. As the body ages, several changes happen that can contribute to weight gain, including hormonal changes, a decrease in muscle mass, and a slowing metabolism. Understanding how aging and weight gain are related is essential for managing healthy weight throughout life.

Throughout adulthood, especially in middle age and beyond, there is a gradual increase in fat mass and a decrease in lean muscle mass. This change is partially due to changes in energy balance, where fewer calories are burned than consumed. Weight gain during aging is often linked to lifestyle factors, genetics, and chronic diseases, such as diabetes or thyroid problems. In this context, it’s crucial to examine the causes, symptoms, prevention strategies, and treatment options to maintain a healthy weight while aging.

Causes of Weight Gain with Aging:

There are several factors that contribute to weight gain as we age, which can be categorized as biological, behavioral, and environmental:

1. Slowing Metabolism:
   One of the most significant contributors to weight gain with age is a slowing metabolism. As we age, the body burns fewer calories at rest. This metabolic slowdown can lead to an increase in fat storage if caloric intake remains unchanged.
2. Loss of Muscle Mass (Sarcopenia):
   As people age, muscle mass naturally declines, a condition known as sarcopenia. This loss of muscle tissue leads to a reduction in basal metabolic rate (BMR), meaning fewer calories are burned throughout the day. The decrease in muscle mass makes it easier to gain fat and harder to lose weight.
3. Hormonal Changes:
   Hormonal shifts associated with aging, particularly in women during menopause and in men with age-related testosterone decline, can increase fat accumulation, particularly around the abdomen. Insulin resistance can also develop, leading to weight gain.
4. Decreased Physical Activity:
   Many older adults become less active, either due to health concerns, a lack of motivation, or reduced energy levels. Sedentary behavior contributes to weight gain by reducing the number of calories burned during daily activities.
5. Dietary Changes and Poor Nutrition:
   Aging adults may experience changes in taste and appetite. They may also have difficulty chewing or digesting certain foods, leading to poor dietary choices. Additionally, aging may come with less knowledge or ability to prepare healthy meals, which can lead to overeating or consumption of calorie-dense, nutrient-poor foods.
6. Medications:
   Many medications used to treat chronic conditions such as high blood pressure, depression, and diabetes may have side effects that promote weight gain. Common examples include corticosteroids, antidepressants, and antihypertensive drugs.
7. Psychological Factors:
   Emotional changes associated with aging, such as depression, loneliness, or stress, can contribute to overeating and weight gain. Some individuals may use food as a coping mechanism for emotional challenges.

Indications of Weight Gain and Aging:

There are several signs that weight gain may be linked to the aging process. Some of the key indications include:

1. Increase in Belly Fat:
   A common sign of weight gain with age is the accumulation of fat around the abdominal area, also known as visceral fat. This type of fat is particularly concerning because it is associated with an increased risk of metabolic conditions like heart disease, diabetes, and high blood pressure.
2. Changes in Body Composition:
   Even if the scale doesn’t show a drastic weight increase, older adults may notice changes in body shape and composition, including an increase in body fat percentage and a reduction in lean muscle mass.
3. Slower Physical Performance:
   Age-related weight gain may lead to difficulty in performing everyday activities that require strength and stamina, such as walking, climbing stairs, or carrying groceries.
4. Joint Pain and Mobility Issues:
   Gaining weight can put extra strain on joints, particularly in the knees and hips. This can result in pain and difficulty moving, which further discourages physical activity.

Symptoms of Weight Gain and Aging:

The symptoms of weight gain as a result of aging are both physical and psychological. These include:

1. Fatigue and Decreased Energy:
   Weight gain and decreased physical activity can lead to fatigue, as carrying extra weight demands more energy. This can also affect overall motivation to remain active.
2. Difficulty with Sleep:
   Increased weight, especially around the abdomen, can lead to sleep apnea and other sleep disorders, contributing to poor sleep quality and daytime fatigue.
3. Breathlessness:
   Gaining excess weight can lead to shortness of breath, especially during physical exertion. It may also contribute to the development of respiratory conditions like asthma or obstructive sleep apnea.
4. Mental and Emotional Symptoms:
   Weight gain can have psychological effects, including low self-esteem, anxiety, and depression, particularly if an individual feels that their body is changing in ways they cannot control.

Prevention Strategies for Weight Gain and Aging:

While weight gain may be inevitable for some as they age, there are various strategies to prevent excessive weight gain or mitigate the effects of aging on the body:

1. Engage in Regular Physical Activity:
   Physical activity is critical in maintaining a healthy weight and preventing the age-related decline in muscle mass. A mix of cardiovascular exercises (such as walking or swimming), strength training, and flexibility exercises (like yoga) can help maintain muscle mass and boost metabolism.
2. Eat a Balanced Diet:
   A nutrient-rich diet that includes lean proteins, fruits, vegetables, whole grains, and healthy fats is essential. Older adults should focus on portion control and avoid calorie-dense, nutrient-poor foods.
3. Stay Hydrated:
   Drinking enough water is often overlooked, but it’s essential for maintaining metabolism, digestion, and overall health.

Introduction & Background

For many men, weight gain is typically viewed as a challenge, either due to an inability to put on muscle mass or the difficulty in increasing overall body weight. Unlike weight loss, which often focuses on reducing body fat, gaining weight can be about increasing muscle mass or, in some cases, improving overall body composition. Achieving a healthy weight gain involves understanding not only the science of muscle growth but also factors such as diet, exercise, and lifestyle changes. This guide provides insights into healthy weight gain strategies, causes, myths, facts, and treatments, with an emphasis on how to gain weight effectively without compromising overall health.

Gaining weight for men typically revolves around one of two goals: enhancing body mass or increasing strength and performance in athletic endeavors. Weight gain, when done correctly, can lead to improved muscle mass, better performance in physical activities, and enhanced energy levels.

Causes of Weight Gain in Men

There are several factors that contribute to weight gain, some of which are controllable and others that are not. Here are the primary causes:

1. Caloric Surplus: Weight gain occurs when a person consistently consumes more calories than they expend. In this state of a “caloric surplus,” the body stores the extra calories as fat or, if combined with the proper exercise routine, as muscle.
2. Genetic Factors: Genetics play a significant role in how the body gains and stores weight. Some men may have a natural tendency to store fat more readily, while others may struggle to put on muscle mass. Factors such as body type (ectomorph, mesomorph, or endomorph) influence how weight is gained.
3. Poor Eating Habits: A diet high in processed foods, sugars, unhealthy fats, and low in nutrient-dense calories can lead to unhealthy weight gain, often in the form of fat accumulation rather than muscle growth.
4. Sedentary Lifestyle: Physical inactivity can result in weight gain because the body isn’t burning enough calories through daily movement and exercise. Lack of exercise can lead to fat gain over time.
5. Medical Conditions: Certain conditions like hypothyroidism (underactive thyroid), diabetes, polycystic ovary syndrome (PCOS), or hormonal imbalances can make it more difficult for men to maintain a healthy weight or gain muscle mass.
6. Stress and Mental Health Issues: Stress leads to increased production of cortisol, a hormone that can drive the body to crave comfort foods high in sugar and fat, potentially leading to weight gain. Additionally, stress may contribute to emotional eating or loss of appetite, affecting one’s ability to gain weight healthily.
7. Aging: As men age, their metabolism naturally slows, and muscle mass begins to decline, making it harder to gain weight without extra effort.

Indications of Healthy Weight Gain

Healthy weight gain focuses on building muscle rather than accumulating fat. Some signs that the weight gain is healthy include:

1. Increased Muscle Mass: One of the most reliable indicators of healthy weight gain is an increase in lean muscle mass. This typically results from a combination of strength training and a protein-rich diet.
2. Improved Strength and Endurance: As muscle mass increases, so should strength. A gradual increase in physical performance, such as being able to lift heavier weights or run longer distances, is a positive sign of effective weight gain.
3. Higher Energy Levels: With proper nutrition and training, the body can develop better energy reserves. Healthy weight gain, especially through muscle development, can provide you with more energy for both daily activities and physical exertion.
4. Better Physical Performance: Increased body mass can improve physical performance, particularly for athletes or individuals engaged in strength or power-based sports (e.g., bodybuilding, weightlifting, football).

Symptoms of Unhealthy Weight Gain

While healthy weight gain involves muscle development, unhealthy weight gain is characterized by excessive fat accumulation. Symptoms of unhealthy weight gain include:

1. Excess Belly Fat: An increase in visceral fat (fat that accumulates around the abdomen) is particularly concerning as it can increase the risk of heart disease, diabetes, and other metabolic conditions.
2. Shortness of Breath: Excessive weight, especially when it’s not the result of muscle gain, can place strain on the cardiovascular system, causing breathing problems during physical exertion.
3. Joint Pain: Extra body fat places additional stress on the joints, particularly the knees and hips, leading to discomfort and potential long-term joint problems.
4. Skin Health Issues: Rapid weight gain can lead to skin conditions such as stretch marks or acne, especially if fat is rapidly accumulated.
5. Fatigue: Gaining weight too quickly in the form of fat can cause fatigue due to an inefficient metabolism and a higher load on the body’s organs and systems.

Prevention Strategies for Healthy Weight Gain

To ensure that weight gain is healthy and sustainable, it’s important to adopt strategies that promote muscle growth and overall health:

1. Eat Nutrient-Dense Foods: Focus on high-calorie, nutrient-dense foods such as lean meats, whole grains, vegetables, healthy fats (like avocados and olive oil), and nuts. Protein-rich foods like chicken, eggs, and fish are essential for muscle growth.
2. Exercise Regularly: Strength training is critical for healthy weight gain. Incorporate exercises such as squats, deadlifts, bench presses, and pull-ups that stimulate muscle growth. Cardiovascular exercises are also important for heart health, but they should be balanced with strength training.
3. Track Caloric Intake: Use apps or journaling to track calories and ensure you’re in a caloric surplus. Keep track of your macronutrient breakdown (proteins, fats, and carbohydrates) to support muscle growth rather than fat accumulation.
4. Get Adequate Sleep: Sleep is crucial for muscle recovery. During sleep, the body repairs muscle fibers that have been broken down during strength training. Aim for 7-9 hours of sleep per night.
5. Manage Stress: Chronic stress can hinder weight gain efforts and contribute to emotional eating. Meditation, yoga, or simply managing work-life balance can prevent stress-related weight gain.

Myths and Facts About Weight Gain

Myths:

1. You Can Gain Weight by Eating Anything: Not all calories are equal. Empty-calorie foods such as sugary snacks or fried foods may lead to unhealthy fat gain, not muscle gain.
2. Cardio Is Counterproductive for Weight Gain: While excessive cardio can burn calories, moderate cardio helps improve cardiovascular health and aids in fat loss, which complements muscle gain.
3. Supplements Are a Must: While supplements like protein powders or creatine can help, a well-balanced diet rich in whole foods should be the foundation of any weight gain program.

Facts:

1. Protein Is Key: Protein is essential for muscle growth and repair. Consuming sufficient protein (around 1.6 to 2.2 grams per kg of body weight) is necessary for healthy weight gain.
2. Strength Training Matters: Resistance training is essential to stimulate muscle growth, especially when combined with a caloric surplus.
3. Weight Gain Is About Consistency: Regularly consuming more calories than you burn and incorporating strength training consistently will eventually result in healthy weight gain.

Treatments and Therapy for Weight Gain

Medication-Based Treatments:

• Anabolic Steroids: Prescribed for men with low testosterone or conditions that hinder muscle growth. These steroids can increase muscle mass, but they come with potential side effects, including liver damage, increased aggression, and heart problems.
• Appetite Stimulants: Medications like megestrol acetate are sometimes prescribed to increase appetite in individuals who struggle to eat enough.

Surgical Treatments:

• Bariatric Surgery: While used for weight loss in obese individuals, bariatric surgery may be used in extreme cases to address rapid, unhealthy weight gain. However, this is rare and only used under medical supervision.

Physical Therapy and Rehabilitation:

• Exercise Prescription: Physical therapists can guide you in developing a program to build muscle while avoiding injury. Rehab programs also ensure recovery after injuries that may prevent weight gain.

Lifestyle and Behavioral Interventions:

• Dietary Changes: Work with a nutritionist to develop a meal plan that ensures you are consuming enough calories to gain weight without overdoing unhealthy foods.
• Behavioral Therapy: In some cases, psychological factors may prevent healthy eating. Behavioral therapy can help address these issues and promote positive eating habits.

Alternative and Complementary Medicine:

• Herbal Supplements: Certain herbs, like fenugreek, may help increase appetite or aid digestion, supporting weight gain efforts. Always consult with a healthcare provider before trying new supplements.
• Acupuncture: Some studies suggest acupuncture can stimulate hormone production and improve metabolism, potentially aiding in weight gain efforts.

Introduction & Background

The goal of a best weight gain diet is to achieve healthy and sustainable weight gain, especially for individuals who are underweight or have difficulty gaining weight. Unlike weight loss, weight gain focuses on increasing muscle mass rather than just adding fat, as gaining lean mass improves overall health, strength, and fitness. A proper weight gain diet includes higher calorie intake, ensuring nutrient-dense foods, and incorporating strategies to help the body build muscle rather than fat.

Weight gain diets can be important for:

• Underweight individuals: Those with a Body Mass Index (BMI) lower than 18.5, often due to poor nutrition, genetics, or illness.
• Athletes and bodybuilders: People seeking to gain muscle mass for performance or aesthetic purposes.
• People recovering from illness: Conditions like cancer, chronic diseases, or surgeries can lead to muscle wasting, requiring a weight gain diet.
• Children and adolescents: Who might be experiencing growth spurts or struggling to meet nutritional needs.

Causes of Best Weight Gain Diet

The need for a weight gain diet may stem from several different causes:

1. Genetic Factors: Some individuals have a naturally high metabolic rate. People with a fast metabolism burn calories at a higher rate than average, leading to difficulty in gaining weight.
2. Medical Conditions: Certain conditions may make it harder to gain weight, such as:
   • Hyperthyroidism: An overactive thyroid causes an increase in metabolism, often resulting in unintentional weight loss.
   • Celiac disease or Crohn’s disease: Both of these impair nutrient absorption, leading to malnutrition.
   • Cancer: Patients with cancer often experience weight loss due to the body’s increased energy needs during illness, and treatments like chemotherapy can reduce appetite.
   • Digestive disorders: Conditions like irritable bowel syndrome (IBS) or malabsorption issues make it difficult to absorb nutrients from food.
3. Psychological Factors: Mental health conditions such as depression or eating disorders like anorexia nervosa can cause a loss of appetite and hinder weight gain.
4. Increased Activity Level: Athletes, particularly those in endurance sports or bodybuilding, often burn more calories than they consume. Without a sufficient caloric intake, they may struggle to maintain or gain weight.

Indications for Best Weight Gain Diet

A best weight gain diet is indicated for individuals who experience the following conditions:

1. Underweight or malnourished: If you have a BMI under 18.5 or you feel weak or fatigued due to insufficient nutrition, a weight gain diet can help restore healthy weight.
2. Loss of Muscle Mass: Individuals who experience muscle wasting due to illness, injury, or aging need to increase their protein intake and calories to regain muscle mass.
3. Poor Appetite: Conditions like depression, chemotherapy, or certain medications may reduce appetite, making it difficult to maintain or gain weight. An appetite stimulant-based weight gain diet may be required.
4. Recovery Post-Illness: Individuals recovering from severe illness, surgery, or trauma need additional calories to support healing and regain strength.
5. Need to Build Muscle Mass: Athletes or bodybuilders who want to increase muscle mass and strength benefit from a weight gain diet that focuses on high-protein, calorie-dense foods.

Symptoms Indicating the Need for a Weight Gain Diet

Some common symptoms suggesting the need for a weight gain diet include:

1. Fatigue and Weakness: Feeling consistently tired or weak despite rest could be a sign of undernourishment.
2. Inability to Maintain Weight: Even after eating regularly, you may be losing weight or struggling to put on weight.
3. Difficulty Building Muscle: Despite regular exercise, especially strength training, you may find it difficult to gain muscle mass.
4. Digestive Issues: Difficulty absorbing nutrients or issues like bloating, nausea, or diarrhea may indicate a problem that requires a nutritional intervention.
5. Frequent Illnesses: A weakened immune system due to lack of adequate nutrition can make you more susceptible to infections.

2. Eat More Frequently:
   • Eating 5-6 small meals throughout the day can increase your calorie intake without causing discomfort.
   • Snacks: Include calorie-dense snacks like protein bars, trail mix, and smoothies.
3. Strength Training:
   • Resistance or weight training is key to ensuring that the weight you gain is in the form of muscle rather than fat. Compound exercises such as squats, deadlifts, and bench presses promote muscle growth.
4. Ensure Adequate Hydration:
   • Staying hydrated is crucial, but it’s important not to drink too much water before meals, as it can reduce appetite.
5. Monitor Progress:
   • Track your calorie intake and weight regularly to adjust your diet accordingly. Use a food diary or an app to ensure you’re consuming enough.

Myths and Facts About Best Weight Gain Diet

Myth 1: “You can gain weight quickly by eating junk food.”

• Fact: While junk food may lead to rapid weight gain, it does not provide the essential nutrients needed for healthy muscle development. A balanced diet with whole foods is crucial for sustainable weight gain.

Myth 2: “Protein shakes are the only way to gain weight.”

• Fact: Protein shakes can be a convenient addition, but whole foods are better for overall nutrition. Protein from food sources like chicken, fish, eggs, and legumes offers a variety of nutrients that shakes may lack.

Myth 3: “Weight gain is all about eating more food, no matter the type.”

• Fact: A quality weight gain diet focuses on nutrient-dense, calorie-rich foods that support muscle growth and overall health, rather than simply consuming large quantities of food.

Myth 4: “You can’t gain weight if you have a fast metabolism.”

• Fact: Even those with a high metabolic rate can gain weight by eating more than their calorie expenditure. It may require careful planning and frequent meals.

Myth 5: “Carbs and fats should be avoided when gaining weight.”

• Fact: Carbs and healthy fats are essential for providing the energy needed to support muscle growth. They are an important part of any weight gain plan.

Weight loss tips: Trying to lose weight? Poor metabolism can affect your weight loss process. Better metabolism can help you burn more calories. Here are some ways to boost metabolism.

Several factors can affect your weight loss process. Other than your diet and physical activities, metabolism also affects how much weight you will lose. Those with poor metabolism can find it difficult to lose weight as the process can become slow. Improving your metabolism is taking one step forward towards weight loss. Metabolism is the process by which your body converts what you eat and drink into energy. The number of calories your body burns while performing various tasks is known as the basal metabolic rate or metabolism. It is not the only factor responsible for weight loss but it can help you burn more calories and result in effective weight loss. You can boost metabolism with some simple tips and tricks. Here are some ways to boost metabolism and weight loss.

Weight loss tips: Here’s how you can boost metabolism and lose weight effectively

1. Add more protein to your diet

Protein is good for weight loss. High protein diet has gained huge popularity in the past year as it contributes to weight loss. Protein consumption can boost metabolism as well as keep you full for longer. This will help you consume fewer calories as well. Most people believe that protein only helps in building muscles. But it can help you boost metabolism as well as contribute to weight loss.

2. Try high-intensity workout

High-intensity workout can help you burn a huge amount of calories and burn fat. It can also help you boost metabolism. You can make changes in your workout routine and try high-intensity workout at least twice a week.

3. Stay hydrated

Proper hydration is extremely important for better metabolism. Simply drink more water throughout the day. Drinking more water also supports weight loss directly. You can replace various drinks you consume throughout the day with water. Stop consumption of carbonated drinks and packed fruit juices. In summers you can drink cold water to boost metabolism.

4. Drink green tea

Consumption of green tea is quite popular for weight loss. Green tea is also loaded with several health benefits other than weight loss. Green tea consumption will offer you better metabolism.

Several factors can unknowingly slow down your metabolism. A sedentary lifestyle or consumption of very few calories can lead to poor metabolism. You should also try strength training and ensure better sleep.

Despite trying out various methods to lose weight, if you are still not able to get the desired results, there is a need to revamp your goals. While this may seem like a difficult task, here is some advice from nutritionist Lovneet Batra who lists down what exactly needs to be done. Take a look!

According to Batra, it’s important to keep a log of what one’s diet on a daily basis that helps identify key issues in one’s routine. “It helps you understand how much you’ve eaten, what your calorie intake is and what the gap between your meals is. Through this analysis you are able to make an accurate assessment of your progress and can make changes accordingly for better results,” she said in the Instagram post.

Here is what she suggests that we avoid

Skipping meals

Not taking enough protein

Not doing strength training

Not maintaining a food journal

Only focusing on the weight scale

Here’s why these pointers matter

*There is a reason why skipping meals is not a good idea. Blood sugar decreases when one skips meals, which, in turn, makes people feel irritated and fatigued. It also leads to the production of cortisol that leads to stress. When one skips meals, the metabolism goes for a toss which hinders weight loss.

*If taking a high protein diet enables weight loss, the reverse also stands true. When the diet is low on proteins, the muscles begin to atrophy (waste)– by taking Lean Body Mass (LBM), strength, and energy with them. This hampers weight loss plans. Proteins help to control cravings and a lack of it can increase binge-eating. According to Batra, one should take protein, especially after a workout to repair all the muscle tissue that breaks down during the strenuous workout.

*Not spending time on strength training and focussing only on cardio will only lead you to reach a plateau and your body will not be strong, says Batra.

*Awareness regarding what one is eating and in what portions is necessary for weight loss. A food journal whether in a written or photographic form is quite helpful to track progress.

Batra says that it’s not always a good idea to eye the weighing scale as that leads to only weight gain/loss-oriented idea of health which is short-term. “Being obsessed with what you’re weight scale says leads you to look at fitness as a short term goal and that will make the entire process temporary. Being fit, eating healthy is a daily process and you have to be patient about your results,” she advises.

Washington: A recent study found that HIV-infected cells release vesicles that contain a viral protein called Nef, further damaging cholesterol metabolism and triggering inflammation in uninfected bystander cells.

HIV infects only a limited repertoire of cells expressing HIV receptors. But HIV infection is also associated with conditions involving the dysfunction of cells that cannot be infected by HIV, such as hardening of the arteries, dementia, kidney impairment, and certain heart problems.

These HIV-associated conditions persist even after the successful application of antiretroviral therapy when no virus is found in the blood. Many of these conditions involve impairments in cholesterol metabolism. In the new study published in the journal of PLOS Pathogens, researchers examined the mechanisms that may contribute to HIV-associated metabolic conditions.

The results showed that the HIV protein Nef is released from infected cells in vesicles that are then rapidly taken up by uninfected bystander white blood cells, impairing cholesterol metabolism in these cells.

This impairment caused the formation of excessive lipid rafts discrete lipid domains present in the external leaflet of the plasma membrane and the re-localisation of inflammatory receptors into rafts, triggering inflammation. The findings demonstrate how a single viral molecule released from infected cells into circulation may contribute to a range of pathogenic responses.

“Our study points to a common mechanism of various co-morbidities of HIV infection. This opens a possibility to target this mechanism using drugs affecting cholesterol metabolism to treat several comorbidities in people living with HIV,” said one of the researchers of the study, Dmitri Sviridov.
