The nation is left shocked after the death of actress Mishti Mukherjee due to renal failure as a result of 'Keto diet' . Keto diet leads to an overload consumption of protein and burdens the kidney function and should not be made a permanent diet schedule.

What Is a Keto Diet ?

Keto diet is a health fad that refuses to die. The diet, which is a quick and reliable way to lose weight, has been a rage among many celebrities, including comedian Tanmay Bhat and American TV star Kim Kardashian, as FIT reported earlier.

The keto diet is a high-fat and low-carb diet which relies on breaking down fat for energy instead of carbohydrates. High on fat, moderate protein and near-zero carbs, it is known to achieve wonders when it comes to weight loss. So, you’ll have to say goodbye to things like bread, sugar and rice.

Nutritionists say that this is only good for quick short-term weight loss. And it should only be done it for a period of 10-12 days, not more than that.

A recent study from Harvard University in the US had revealed that the ketogenic diet has numerous risks. Kidneys help metabolize protein, and the keto diet may overload them.

It is also associated with an increase in "bad" LDL cholesterol, which is also linked to heart disease.

According to Salil Jain, Director-HOD, Nephrology and Renal Transplant, Fortis Memorial Research Institute in Gurugram, Keto diet is high in fats and proteins and low carbohydrates.

If you consume a lot of these foods, especially red meat, it may lead to a higher risk of forming kidney stones.

"It may also worsen the kidney functioning of those who already have kidney diseases. The theory is that higher intake of animal food products can make your urine more acidic i.e. increase level of excretion of calcium from your urine," Jain said.

There are numerous studies which say that the keto diet may reduce citrate level that's released in your urine. Citrate binds calcium and prevents kidney stone formation. A reduced level of citrate may raise the risk of developing a stone.

Studies claim that this overdrive of the kidney leads to excess amounts of sodium, calcium and potassium excretion, the expert said.

"Keto diet is one of the hardest diet schedules to follow which primarily focuses on weight loss. It surely has the potential risk of other health problems as the user is on high proteins and fats intake," said Priya Bharma, Senior Dietician, Sri Balaji Action Medical Institute in New Delhi.

"A person with ideal or lesser body weight is generally not suggested to go for it. It is not suggested to continue for more than 45 days in one go as the body starves for other nutrients as well as high protein puts pressure on the kidney without other related precautions," she noted.
