It’s a low-carb eating plan popularized by famous individuals, claiming to enable effortless weight loss by eliminating items such as potatoes, pasta, and bread.
However, the popular Keto diet might increase the likelihood of encounteringdiabetes, high cholesterol levels and fatty liver disease, recent studies have indicated.
American scientists found that individuals on a high-fat, low-carbohydrate diet were significantly more prone to experience insulin resistance and had reduced insulin levels, increasing the likelihood of developing diabetes.
The group also found out they had an increased likelihood of experiencing ‘dangerously’ elevated levels of bad cholesterol, which can accumulate in the body and may lead to fatty liver disease.
Dr. Molly Gallop, a postdoctoral researcher in metabolic biology at the University ofUtah, said: “We noticed increased glucose intolerance and reduced insulin production the longer the animals remained on a ketogenic diet.”
Thus, the use of the keto diet as a remedy for metabolic conditions warrants scrutiny despite early signs of health improvement.
A ketogenic diet works by significantly reducing high-calorie carbohydrates, helping individuals reach a condition known as ketosis.
This means no bread, pasta, rice, and no starchy veg such as corn, beans and squash and almost no fruit.


If carbohydrates are absent, the body begins to utilize stored fat as a source of energy, aiding in weight loss.
In the research, scientists provided a group of male and female mice with a high-ketogenic diet, which consisted of 90 percent fat.
Three additional groups of mice were given a low-fat diet, consisting of 10 percent fat, a standard 60 percent high-fat diet, and alow-fat, moderate-protein diet consisting of 10 percent fat and 10 percent protein.
After a follow-up period of one year, the researchers found that the mice on the high-keto diet initially experienced weight loss.
Nevertheless, as time passed, they developed fatty liver disease, severe glucose intolerance, and hyperlipidemia—elevated levels of cholesterol and fat in the bloodstream.
The scientists also found that cholesterol levels were elevated in all groups among male mice when compared to female mice.
Individuals following a strict keto diet also experienced improved insulin sensitivity and maintained low insulin levels.
Writing in the journal Science Advances, they said: ‘WWhile male and female mice on a high keto diet are safeguarded against weight gain when compared to those on a conventional high-fat diet, they suffer from significant glucose intolerance, elevated plasma lipids, and reduced insulin secretion, with males additionally developing fatty liver disease.

Fatty liver, also known as hepatic steatosis, refers to the accumulation of fat within liver cells.
They further stated that the results indicate that employing a ketogenic diet as a long-term eating plan could potentially negatively impact metabolic health.
Additional research on different mouse strains, other animals, and humans is needed to establish if metabolic issues associated with the ketogenic diet are widespread.
A ketogenic diet typically includes 75% fat, 20% protein, and just 5% carbohydrates.
In comparison, the NHS’s guidance on a nutritious and balanced diet recommends 30 percent fat, 15 percent protein, and 55 percent carbohydrates.
Most individuals following a ketogenic diet are recommended to consume between 20g and 50g of carbohydrates daily.
A slice of wholemeal bread with 14g of carbs and a banana with 20g suggests that individuals following a keto diet must carefully plan their meals.
Although several studies highlight the possible risks associated with a ketogenic diet, it has grown more widespread.
Several celebrities including Gwyneth Paltrow, Jennifer Aniston, Halle Berry, and Kourtney Kardashian have previously discussed their experiences with a low-carb diet.
- Even with health advisories, might a high-fat ketogenic diet truly balance cholesterol levels and lower the chances of diabetes?
- Could the dangerous side effects of the keto diet be the reason Kourtney Kardashian abandoned it in favor of better options?
- Are the significant advantages of fasting potentially outweighed by its harmful effects, such as a higher likelihood of heart disease and ketoacidosis?
