The ketogenic diet has become one of the fastest-growing dietary trends, but experts have warned that many of its advocates are unaware of the dangerous side effects the diet can cause.
According to Healthline.com, the ketogenic diet, commonly known as keto, is a low-carb, high-fat diet that shares similarities with low carb and Atkins diets. A reduction of carbohydrate intake and increase in fats place the body in a metabolic state called ketosis.
However, the diet has led to severe side effects for some people.
“The keto diet should only be done under clinical supervision, and only for brief periods of time,” said Dr. Ruwaida Idrees, a nutritionist, CEO and owner of Hayati Ghethaei, a catering company.
She added that the keto diet should only be considered in “extreme cases,” because it can do “more harm than good.”
Idrees said: “It can cause damage to the heart, since the heart is also a muscle.”
Consulting a doctor, completing necessary tests and discussing goals with a clinical dietitian should all be considered before starting a keto diet, she added.
Idrees said there are many misconceptions surrounding the keto diet and exercise, adding that exercise can still reduce the risk of heart disease, obesity and other health conditions.
People need to be careful about the types of exercises they practice, she said. “The keto diet can also affect your performance during certain exercises, and you won’t be able to work out as intensely or as often as before.”
Fouz Ghannamil, a fitness trainer, told Arab News that the diet appeared to work for many people. “It is good, but my own opinion is that the human body needs more nutrition than just fat and a really small dose of carbohydrate.”
She added: “It has a high portion of proteins which is good, but the fat sources, no matter how good they are, are a bit too much. It is better in my opinion that the portion of fat and carbs is balanced.”
Ghannamil suggested a better alternative for people looking to shed pounds this year — sticking to a diet of “80 percent healthy food and 20 percent junk food.
“Because naturally, your mind will desire junk food that is not natural, however, it has loads of fat in and your body can use it as an energy source.”
She warned people considering a new diet to stick to a balanced nutrition pyramid that contains everything they need: Protein, carbohydrates and fat.
She also added that people should avoid diets based solely on numbers rather than personal experience.
Idrees, on the other hand, proposed the Mediterranean diet as a simpler alternative to the keto diet, saying that it has a good balance of seafood and other sources of proteins, moderate portions of dairy and a limited intake of red meat.
