Keto Diet: A Complete User Guide (End-to-End)

Discover everything you need to know to begin, maintain, and optimize a ketogenic diet — based on real research, scientific experiments, benefits, and risks.

What is the Keto Diet?

The Ketogenic (Keto) Diet is a low-carbohydrate, high-fat, moderate-protein diet that alters your body’s metabolism. Instead of burning glucose (carbs) for energy, the body enters a state called ketosis, where it burns fat for fuel.

Typical Keto Macros:

• 70–75% fat
• 20–25% protein
• 5–10% carbs (usually under 20–50 grams net carbs/day)

How the Keto Diet Works (Scientifically)

When you drastically reduce carbs:

• Insulin levels drop
• Your body starts breaking down fat into ketones (BHB, acetoacetate, acetone)
• These ketones become the new fuel source for your brain and muscles

This metabolic shift mimics fasting and triggers processes like:

• Fat oxidation (burning stored fat)
• Reduced inflammation
• Stable energy levels
• Improved cognitive clarity

Research and Experiments

Numerous scientific studies have evaluated the keto diet’s impact:

Weight Loss

• Virta Health (2017): 218 Type 2 diabetics lost an average of 12% body weight in 12 months on keto and reduced HbA1c by 1.3%.
• Journal of Clinical Endocrinology (2002): Keto showed greater fat loss compared to a low-fat diet, even when calories were equal.

Epilepsy

• Originally developed in the 1920s for epilepsy. Still used today, especially for drug-resistant childhood epilepsy.

Type 2 Diabetes

• Keto has shown to lower blood glucose, reduce insulin resistance, and in many cases, reverse Type 2 diabetes.

Cognitive Health

• Early studies show potential in Alzheimer’s, Parkinson’s, and brain injury recovery due to ketones being a “cleaner” energy source.

Proven Benefits of the Keto Diet

Benefit	Description
Fat Loss	Burns fat stores, especially visceral fat
Appetite Control	Ketones suppress hunger hormones (ghrelin)
Mental Clarity	Steady fuel = less brain fog, improved focus
Blood Sugar Stability	Great for prediabetics and diabetics
Improved HDL/Triglycerides	Keto tends to increase HDL and reduce triglycerides
Anti-Inflammatory	Reduced CRP markers in many studies
Neuroprotective	May protect against cognitive decline

Risks and Side Effects

Risk	Description
Keto Flu	Fatigue, brain fog, headache in the first 3–5 days
Electrolyte Imbalance	Sodium, potassium, magnesium loss from diuresis
Constipation	Low-fiber intake from carb restriction
Overconsumption of processed fats	Eating poor-quality fats (e.g., bacon, salami) can harm heart health
Not suitable for some conditions	Pregnant women, kidney issues, pancreatitis patients should consult doctors
Long-term unknowns	Some long-term studies are inconclusive on keto’s impact after 5+ years

How to Start the Keto Diet – Step-by-Step

Step 1: Understand Your Macros

Use a calculator (like ruled.me or Keto Calculator) to set your:

• Total daily calories
• Fats (~70%)
• Proteins (~20–25%)
• Net carbs (<20–50g)

Step 2: Clean Out Your Kitchen

Remove:

• Bread, rice, pasta
• Sugary snacks and sodas
• High-carb fruits (bananas, grapes)
• Processed foods

Step 3: Stock Up on Keto-Friendly Foods

Category	Examples
Fats	Avocados, olive oil, coconut oil, ghee, butter
Proteins	Eggs, chicken, beef, pork, salmon, sardines
Low-Carb Veggies	Spinach, kale, zucchini, cauliflower, broccoli
Dairy	Cheese, heavy cream, full-fat yogurt (unsweetened)
Nuts & Seeds	Almonds, chia, flax, walnuts (moderate amount)
Condiments	Mustard, mayo, hot sauce, vinegar (no sugar)

Step 4: Track Your Intake (At Least Initially)

Use apps like:

• Carb Manager
• MyFitnessPal
• KetoDiet App

This helps ensure you stay within your carb limit.

Step 5: Stay Hydrated + Electrolytes

Due to water loss on keto, take:

• 2–4g sodium/day (Himalayan salt or bouillon)
• 500mg potassium
• 300mg magnesium

This prevents keto flu, cramps, fatigue.

Things to Avoid on Keto

High-Carb Foods:

• Bread, pasta, rice, potatoes
• Cereals, oats, granola
• Beans and legumes
• Most fruits (except berries)
• Sugary drinks, juices, soda
• Alcohol (especially beer, sweet cocktails)
• Packaged low-fat products (usually high in sugar)

“Dirty Keto” Pitfalls:

• Bacon-only meals without veggies
• Artificial sweeteners in excess (can spike insulin)
• Processed keto junk (keto cookies, chips, etc.)
• Not eating enough real food or fiber

What is Ketosis? How Do You Know You’re in It?

When in ketosis, your liver produces ketones used by your body and brain for energy.

Signs you’re in ketosis:

• Reduced hunger
• Increased focus
• Dry mouth / metallic taste
• Urine or breath ketone test shows positive
• Weight loss (initially water, then fat)

How to Measure Ketosis

1. Urine strips (cheap, easy, but not always accurate)
2. Breath meters (like Ketonix – reusable)
3. Blood ketone meters (most accurate – e.g., Keto Mojo)

How Long Does It Take to Enter Ketosis?

• Usually 2–4 days with <20g carbs/day
• Exercising + intermittent fasting can speed up the process
• Hydration + electrolytes help manage symptoms

Sample 1-Day Keto Meal Plan

Meal	Example
Breakfast	Scrambled eggs in butter + spinach + avocado
Lunch	Chicken thigh + olive oil salad + feta
Dinner	Salmon + zucchini noodles + garlic cream sauce
Snack	Bulletproof coffee or a handful of almonds

Who Should Be Cautious or Avoid Keto?

• People with kidney/liver/pancreas disease
• Pregnant or breastfeeding women
• Those with a history of eating disorders
• If you’re on diabetic or blood pressure medication – always consult your doctor

Final Thoughts

The Keto Diet isn’t just another trend. Backed by science and clinical use cases (like epilepsy, obesity, and diabetes), it’s a powerful metabolic tool when done correctly. But like any serious diet, it requires planning, balance, and personalization.

Summary

• Keto = High fat, low carb, moderate protein
• Trains body to burn fat instead of glucose
• Helps in weight loss, blood sugar control, mental clarity
• Comes with side effects if not managed properly
• Avoid sugars, grains, starchy veggies, processed junk
• Stay hydrated, track macros, and focus on whole foods

Briana Culberson and her husband, Ryan, are counting down the days until they can welcome their third baby to their brood. The Real Housewives of Orange County alum has shared the secrets to maintaining her Keto-friendly diet while pregnant since announcing that she was expecting. And now, at 37 weeks pregnant, she’s opening up on Instagram about how she’s made this “by far [her] healthiest pregnancy yet.” 

On November 3, Briana snapped a quick mirror selfie to flaunt her adorable growing baby bump. Vicki Gunvalson’s daughter wore a classic, white tee and her go-to pair of black leggings with a pair of shearling slippers to show off her bump.

In her caption, Briana opened up about remaining on the Keto diet while pregnant. “I have a lot of health problems including lupus and a clotting disorder among other medical diagnoses,” Briana explains in her November 3 Instagram post. “My team of doctors have all told me that it is healthy for ME to continue the ketogenic diet throughout this pregnancy. This is my 6th pregnancy, we have had 3 miscarriages. This is by far my healthiest pregnancy yet.”

Briana shared that her struggles to shed pounds after her first two children are what led her to embrace a Keto lifestyle. “With my other 2 boys I gained way too much weight than I’m comfortable with sharing, it’s embarrassing…I’ve only gained 30 lbs this pregnancy and have only bought 1 pair of maternity pants and 1 pair of maternity shorts. Other than that I am still in my same clothing I was in prior to my pregnancy at my lowest weight.”

“Ryan and I have been keto for almost 3 years,” she said. “It’s become a lifestyle and we don’t stress over counting macros or calories. We aim to stay under 20g net carbs per day just by using mental math. For me personally I don’t want to obsess about what I’m eating or track too much because I will become consumed by it.”

Making these Keto mistakes?

Keto is a popular diet and backed by a lot of celebs, which is reason enough for people to follow it. From Kim Kardashian to Bhumi Pednekar, there are many who swear by this diet plan for weight loss.

Does Keto work for everybody?

The diet, which promotes consumption of high fat and low-carb content food has emerged as one of the most successful ways for many people to lose weight but it does come with its fair share of cons. Case in point? Bollywood’s very own transformation diva, Sara Ali Khan famously said, “keto didn’t work for me”.

Despite what people rave about, or sometimes, despite your best efforts, it can happen that the Ketogenic diet doesn’t really spell results for you and does not help you lose weight in the manner you desire. This can be very unsettling and frustrating, given the diet restrictions Keto forces you to adhere to. However, the top reasons why Keto fails to work for some people are common than you think. We tell you why

Eating too much or too little

Following a Keto diet means that you will have to start measuring your food in macro quantities, which can be quite tricky to get used to. If you are not sticking to the designated portion size, you are more prone to making the mistake of either eating too little or eating more than the required quantity. It can also be possible that you consume more carbs than the diet requires you to (accidentally or otherwise), or more fats. Or, if at all, you consume too much protein, as it can push the body out of ketosis (when the body burns fat instead of carbs to gain energy). Any of these mistakes can slow down your metabolism and make it harder for the body to release stored fat, derailing any progress you might have made.

Stress to be blamed?

Race walkers on a low-carbohydrate, high-fat ketogenic diet showed indications of bone loss

A low-carbohydrate, high-fat ketogenic diet could alter bone health in athletes, according to a thought-provoking study of elite race walkers and their skeletons. The study, one of the first to track athletes during several weeks of intense training, finds that those following a ketogenic diet developed early signs indicative of bone loss.

The study adds to the considerable existing evidence that how we eat can affect how exercise affects us. It also raises concerns about possible long-term health effects from popular diet plans, including a high-fat ketogenic diet.

Anyone interested in health, wellness, weight loss, exercise, food or bestseller lists is familiar, by now, with ketogenic diets. Known more familiarly as keto diets, they are extremely low-carbohydrate, high-fat regimens, with as much as 90 per cent of daily calories coming from fats.

Ketogenic diets, if followed scrupulously, reshape how our bodies fuel themselves. Because carbohydrates can be rapidly metabolised, our bodies typically turn to them first for energy, whether the carbohydrates come from our diets or stored sources in our muscles and livers.

Ketones

But if people follow a low-carbohydrate ketogenic diet, they soon burn through their stored carbohydrates and their bodies start relying on fat for energy. The fat must be broken down first, however, and, as part of that process, the liver creates substances known as ketone bodies that can be converted into energy.

Ketogenic diets are popular now among people hoping to lose weight, control blood sugar or otherwise regulate their health. Some athletes also follow the diet, hoping that it will improve performance, since fat, as fuel, is ample, slow-burning and long-lasting.

Some studies have suggested, though, that low-carbohydrate, high-fat diets might change bone metabolism. Children with epilepsy who use the keto diet to control their condition tend to have low bone density, for instance. And in athletes, going for a day or two without carbohydrates can change some blood markers related to bone health.

But no experiments had tracked bone metabolism in competitive athletes on ketogenic diets for longer periods of time. So, for the new study, which was published in Frontiers in Endocrinology, researchers in Australia decided to ask a group of world-class race walkers if they could fiddle with their food for a few weeks. Thirty of the athletes, all of whom were about to embark on intense training for upcoming world championships and other competitions, agreed. The athletes then sorted themselves into two groups, based on whether they were willing to try a keto diet or not.

About half said that they were and subsequently began a strict low-carbohydrate, high-fat routine. The other men and women continued with a high-carbohydrate diet. All athletes’ meals were matched in terms of how many calories, relative to body weight, they ate.

Before the diets kicked off, though, the researchers drew blood from the athletes before and after a workout, to establish their baseline bone health and other markers of their health and fitness.

Bone is an active tissue, constantly breaking down slightly and remodeling itself in response to the demands we place on it. Knowing this, the researchers checked for the levels of specific substances in the athletes’ blood known to be associated with bone breakdown, rebuilding and overall metabolism.

Then the athletes embarked on 3½ weeks of intense training, while eating mostly fat or mostly carbs. Afterward, the researchers again drew their blood and rechecked the markers of bone health.

Blood markers

They found differences. The markers of bone breakdown were higher now among the athletes on the keto diet than at the start of the study, while those indicating bone formation and overall metabolism were lower. These same markers were generally unchanged in the high-carb athletes. The athletes on the ketogenic diet, in other words, showed signs of impaired bone health.

How their bones might have been affected by their eating is still unclear, said Louise Burke, the head of sports nutrition at the Australian Institute of Sport in Canberra and one of the lead authors of the study. “We believe that the keto diet may affect bone metabolism due to the downstream effects of low-carbohydrate availability on certain hormones, along with other factors,” she said. But more study, of course, is needed.

The researchers also did not look directly at changes, if any, in the athletes’ bone density or follow them beyond 3½ weeks. Whether any worrisome effects on bone health would linger, intensify or disappear after a longer period of high-fat eating remains unknown, as does the question of whether those of us who are not world-class race walkers would be similarly affected, if we work out while eschewing carbs.

But the study does remind us that the interplay of nutrition and exercise is intricate, and we do not yet fully understand its implications for our health.

Burke and her colleagues plan to study the longer-term effects of ketogenic diets and exercise in future studies.

The post Could a keto diet be bad for athletes’ bones? appeared first on MyMedicPlus.

Keto diet is all the rage right now. Celebrities and health influencers all over the Internet are promoting this powerful diet, but is it good for you?

We tackle seven different benefits and side effects in this article. Let’s find out more.

1. Weight loss

Perhaps the most popular of all benefits is weight loss. Keto diet for weight loss is the reason most people get into it.

Theoretically, the body can start to get used to burning fat stores rather than getting its energy from carbohydrates. This is known as ketosis, and it is what people strive to achieve.

This diet has certainly proven to help people lose weight, as long as people stick to it over the long run.

2. Help with epilepsy

Many people have adopted the keto diet for epilepsy. There is a great body of evidence that has shown that it can be beneficial in terms of reducing epileptic seizures and fits.

It is most effective in the pediatric population, with about 50% reduction in seizures after following this diet.

The positive effects are less pronounced for adults, however, many adults have also seen a decrease in the intensity of their seizures.

3. Experiencing the keto flu

Unfortunately, some people report that they start feeling sick after going on the ketogenic diet. Common side effects include feeling sick, vomiting, and feeling lethargic. This is known as the Keto flu and usually comes around after about a week.

Around ¼ people who try it may experience such symptoms because the transition to start burning fat can make you feel tired. If you experience side-effects, try to get more sleep than usual and drink plenty of water.

4. Diarrhea

Diarrhea is a common side effect because this diet is restrictive in terms of limiting the amount of fruit and vegetables that you can eat.

Often people forget to stock up on fiber which is why diarrhea comes around. The gallbladder can also feel overwhelmed and may struggle to break down fat in the diet, leading to further diarrhea.

5. Changes to athletic performance

A lot of athletes are completely convinced by the ketogenic diet for improved performance, however, a recent study in the Journal of Sports Medicine and Physical Fitness has found that participants performed much worse with high-intensity exercise after going on the keto diet.

This study concluded that the body is in more of an acidic state, so it will limit the amounts that one can perform at peak level. However, losing weight is always going to be a massive advantage for athletic performance, so it works both ways.

6. Helping with acne

There are many different courses to acne, and one of them is related to blood sugar. Eating many refined carbohydrates can cause blood sugar to increase and affect skin health.

The keto diet for beginner tells you to restrict the number of carbs, thus limiting the amount of blood sugar in your body. The result is an increased likelihood of acne reduction.

7. Reduction of cancer

We think that one of the most poignant things about keto is that it could prevent certain cancers from forming. Some studies have found that this kind of diet works well as a complementary treatment with radiation therapy and chemotherapy.

The reason for this is that it causes oxidative stress in cancer cells, resulting in their death. The fact that it also reduces blood sugar means that it reduces insulin complications, it is a hormone that can promote some cancers if it fluctuates wildly.

Conclusion

As you have read, there are all sorts of benefits and side effects of a keto diet. Hopefully, now that you have read this article, you’ll be well informed to make your own decisions on the subject. All the best!

In your opinion, what is the keto diet good for? Do you think it could work for you? Tell us your thoughts in the comments section below.

By now, you’re probably familiar with the keto diet these days – the high-fat, moderate-protein, super-low-carb diet has helped people lose weight, gain energy, and transform their lives. But as popular as the diet is, there are still many misconceptions about it.

For starters, many people think you can’t eat any carbs at all in order to get into your body’s fat-burning state of ketosis. In reality, some carbs are allowed as long as you eat about 50 grams or fewer daily. But what about sugar? Keto dieters have all but eschewed the sweet stuff in favor of calorie-free sweeteners like stevia. Just look at this roundup of keto fat bombs: they’re all sugar-free or incredibly low in sugar.

To find out just how much sugar you can eat on the keto diet, we asked Brittanie Volk, PhD, RD, senior clinical and patient engagement specialist at Virta Health, for answers.

“To achieve the many health benefits that a ketogenic diet has to offer, one needs to consume only the amount of carbohydrates that the individual can tolerate to stay in nutritional ketosis,” she told POPSUGAR. “This amount differs from person to person but is generally less than 50 grams of total carbohydrates per day. That means all sources of carbohydrate, including refined sugar, should be limited to as little as possible to avoid the impact carbohydrates can have on blood sugar and insulin levels.”

So while sugar is a carb and does count toward your 50 grams or fewer a day, you should still limit sugar intake so as not to spike your blood sugar. Yes, you can still have it, but make sure that sugar, combined with all your other sources of carbohydrates, stays below your threshold of about 50 grams a day.

THE KETOGENIC OR KETO diet has garnered a lot of attention in recent years as a means of quickly losing weight. Some researchers have also posited that it could be helpful in preventing the spread or recurrence of certain types of cancer, and it’s long been a non-pharmacological means of controlling otherwise untreatable epilepsy in some children. But because the diet is strict, it can be challenging to stick with long term. Enter some modifications that help make the diet a little more accessible and sustainable.

The post Following a keto diet could weaken your bones and increase your risk of injury appeared first on MyMedicPlus.

Adhering to the wildly popular keto diet has been correlated with added strain on the kidneys and cardiac arrhythmia, and a new, small study links going keto with possible consequences on another vital body system: the bones. The study, published in late January in Frontiers in Endocrinology, is the first to look into whether the high-fat, low-carb diet might also adversely affect bone health.

The study only involved 30 people, all of whom were about to start vigorous training for upcoming competitions in race walking. Researchers found more significant signs of bone breakdown in the athletes who followed a keto diet for three and a half weeks, compared to those who continued to simply eat their regular, more balanced diet. That doesn’t necessarily mean that eating virtually zero carbs weakens the bones; researchers didn’t examine bone density, and further study is needed. But Louise Burke, one of the study’s lead authors, told the New York Times that researchers believe the low availability of carbs on keto may very well affect bone metabolism.

Doctors and researchers across disciplines have long decried the keto diet, especially over the past few years, as its popularity as a quick way to lose weight surged. Following the diet correctly involves getting as much as 90 percent of one’s daily calories from fats, which is meant to send the body into a semi-starvation state known as “ketosis.” The idea is that, while in ketosis, ketoers burn through reserved fat stores for energy, rather than churning through readily available carbs. That can (and does) help people drop pounds, but it’s also extremely unsustainable, and appears to come with a whole mess of health issues.

The only known medical use for keto is treating epilepsy in children; it’s also been useful for helping regulate blood sugar levels in people with diabetes. But just because a diet is doctor-approved for specific situations doesn’t mean it’s a good idea to use it “off-label” for weight loss without physician guidance. If your goal is to lose fat, there are plenty of other ways to do that without rotting vital body systems, and almost all of them are far less annoying.

The post New Research Links the Keto Diet to Withered Bones appeared first on MyMedicPlus.

Ketogenic diet that excludes a wide array of essential food groups, can take a toll on our overall health if people are not able to sustain such a drastic change in eating habits that too in a safe manner. As a high-fat, adequate-protein, low-carbohydrate diet known as the Ketogenic diet, has been touted as one of the best weight loss programmes, at the same time been dismissed by many.

Out of the total daily caloric intake, nearly 70 to 80 per cent comes from fat, 20 per cent from protein and the remaining 5 per cent or so are derived from carbohydrates. The carbohydrate deprivation pushes the body into ketosis, which is a state where fat becomes its primary fuel source.

Despite its ability to cause rapid weight loss, this dieting approach doesn’t find many supporters among medical professionals. The Keto diet is usually not recommended by doctors for the reason that it excludes a wide array of essential food groups that are imperative for optimal health, such as grains, fruits, and some vegetables.

Medical professionals caution people to be aware of the difference between weight loss and overall health. Jeffrey Mechanick a medical director at Mount Sinai Heart’s Marie-Josee and Henry R Kravis Center for Clinical Cardiovascular Health quite frankly stated to USA Today that “I wouldn’t recommend the keto diet to anybody.” Vasanti Malik, an adjunct assistant professor of Nutrition at the Harvard TH Chan School of Public Health, expressed her concern regarding this extreme system of eating.

“You want to be mindful because these foods — whole grains, fruits, and vegetables — carry a number of beneficial nutrients — vitamins, polyphenols, fibre — that have been shown time and time again to be beneficial for cardiometabolic health,” Malik told USA Today.

According to Mechanick, depletion of carbohydrates compels the body to scavenge upon its fat and muscle tissue to keep everything up and running. “In theory, the Keto diet basically mimics starvation. If you don’t eat carbohydrates but you eat an excessive amount of fat and protein, you’re still going to waste tissue. The tissue is still going to burn off,” explained Mechanick.

Fad diets such as keto also lead to weight rebound issues with people who are not able to stick to them after losing weight. The answer for sustainable weight loss hence lies with emphasising on the quality of food and not exclusively the number of calories that are consumed.

Mechanik suggests the minimisation of sugars and starches and an increased intake of vegetables, fruits, nuts, and beans.

Malik recommends people to include more grains, fruits, vegetables, and nuts, while limiting saturated fat, added sugar and added sodium. Tidying up your menu, in conjunction with daily physical exercise would be enough to create a solid foundation for health.

The post Keto diet has its own cons appeared first on MyMedicPlus.

The keto diet has gained popularity, unlike any other diet in the recent past. Scores of health articles discuss it daily and so many people are willing to try it after hearing about it from a friend. There are many success stories – people have reported feeling rejuvenated and shedding many kilos. However, the fact remains that long term studies on its effects have not been carried out and the scientific community has not approved it as a weight loss therapy yet. Further research will tell us if the weight loss is sustainable (as many of those who lose weight find it difficult to keep it off) and shed light on its long term health effects.

There may be short term benefits 

A study at Yale involving mice has shown that the ketogenic diet does have good short term health effects. A week on the diet improved metabolism, lowered inflammation and diabetes risk. However, the mice that were on the diet longer than a week regained the weight and became obese and had a higher likelihood of developing diabetes. The researchers attributed this to the high amount of fat in the diet – the mice were consuming more fat than they could burn and burdening their bodies.

What the keto diet consists of 

A ketogenic diet is composed mostly of fat as 90% of the calories are meant to come from fat and proteins make up the remainder. The idea is to deprive the body of carbohydrates as much as possible. Ideally, less than 50g of carbohydrates should be consumed in a day. Vegetables and fruits contain carbohydrates, but leafy greens and certain berries can be consumed, albeit with restraint. Pulses, rotis, and foods containing added sugar will need to be avoided. All kinds of fats are permitted, and unsaturated fats especially so – they make up the majority of the diet.

The diet aims to use a different kind of fuel to run the body. Rather than glucose, a body that has been on the keto diet will run on ketone bodies instead. The liver produces ketone from stored fat, so the body effectively begins burning fat to fuel itself. It believes that it is in a state of starvation when in reality it is not. With the release of ketone bodies, gamma delta T-cells are also released which lower inflammation and risks associated with diabetes. For example, the mice had lower blood sugar at the end of the week. 

Longer-term issues

However, the researchers found that during this fat burning process, fat from the diet continues getting stored in the body anyway. What this meant for the mice was that they started gaining weight after being on the diet for a longer time. This led to obesity and an increased likelihood of getting diabetes. It appears that the high-fat content of the diet eventually works against it.

The researchers hope to use these findings to better understand the workings of the ketogenic diet and perhaps come up with recommendations on the duration of the diet. 

The post Keto Diet: The pros and cons you need to consider before you try it appeared first on MyMedicPlus.

Washington: A ketogenic diet — which provides 99 per cent of calories from fat and protein, and only one per cent from carbohydrates — may produce health benefits in the short term, but negative effects after about a week, according to a study conducted in mice.

The study, published in the journal Nature Metabolism, suggests that the keto diet could, over limited time periods, improve human health by lowering diabetes risk and inflammation.

The keto diet has become increasingly popular as celebrities, including Gwyneth Paltrow, and Kim Kardashian, have touted it as a weight-loss regimen, the researchers noted.

The diet tricks the body into burning fat, said lead author Vishwa Deep Dixit from the Yale University in the US.

When the body’s glucose level is reduced due to the diet’s low carbohydrate content, the body acts as if it is in a starvation state — although it is not — and begins burning fats instead of carbohydrates.

This process in turn yields chemicals called ketone bodies as an alternative source of fuel.

When the body burns ketone bodies, tissue-protective gamma delta T-cells expand throughout the body.

This reduces diabetes risk and inflammation, and improves the body’s metabolism, said Dixit.

After a week on the keto diet, mice show a reduction in blood sugar levels and inflammation, he said.

However, when the body is in this “starving-not-starving” mode, fat storage is also happening simultaneously with fat breakdown, the researchers said.

When mice continue to eat the high-fat, low-carb diet beyond one week, they consume more fat than they can burn, and develop diabetes and obesity, the researchers said.

“They lose the protective gamma delta T-cells in the fat,” Dixit said. Long-term clinical studies in humans are still necessary to validate the anecdotal claims of keto’s health benefits, the researchers noted.

“Before such a diet can be prescribed, a large clinical trial in controlled conditions is necessary to understand the mechanism behind metabolic and immunological benefits or any potential harm to individuals who are overweight and pre-diabetic,” Dixit said.

“Obesity and type 2 diabetes are lifestyle diseases. Diet allows people a way to be in control,” he said.

With the latest findings, researchers now better understand the mechanisms at work in bodies sustained on the keto diet, and why the diet may bring health benefits over limited time periods.

“Our findings highlight the interplay between metabolism and the immune system, and how it coordinates maintenance of healthy tissue function,” said Emily Goldberg, a postdoctoral fellow at Yale.

WASHINGTON: A ketogenic diet — which provides 99 per cent of calories from fat and protein — may produce health benefits in the short term, but negative effects after about a week, according to a study conducted in mice.

The study, published in the journal Nature Metabolism, suggests that the keto diet could, over limited time periods, improve human health by lowering diabetes risk and inflammation.

The keto diet has become increasingly popular as celebrities, including Gwyneth Paltrow, and Kim Kardashian, have touted it as a weight-loss regimen, the researchers noted.

The diet tricks the body into burning fat, said lead author Vishwa Deep Dixit from the Yale University in the US.

When the body’s glucose level is reduced due to the diet’s low carbohydrate content, the body acts as if it is in a starvation state — although it is not — and begins burning fats instead of carbohydrates.

This process in turn yields chemicals called ketone bodies as an alternative source of fuel.

When the body burns ketone bodies, tissue-protective gamma delta T-cells expand throughout the body.

This reduces diabetes risk and inflammation, and improves the body’s metabolism, said Dixit.
