What is Ketogenic Diet?
- The Keto Diet is one of the most popular weight-loss diets the world over.
- It consists of a high-fat, moderate-protein and low-carb diet.
- It helps in weight loss by achieving ketosis — a metabolic state where the liver burns body fat and provides fuel for the body, as there is limited access to glucose.
What constitutes a keto diet?
- A classic keto generally requires that 90 per cent of a person’s calories come from fat, 6 per cent from protein and 4 per cent from carbs.
- But there are many versions doing the rounds since this one was designed for children suffering from epilepsy to gain control over their seizures.
How does it impact the body?
- If we starve the body of carbohydrate, after burning out the glucose, the liver starts breaking down fats for energy.
- Ketosis is common in all kinds of fasting, but in a keto diet, when one is feeding it by giving a lot of fats from outside without carbs, it can become mildly toxic.
- It may lead to many nutrient deficiencies such as carbohydrates, proteins, vitamins (especially vitamin A, D, E, & K) and minerals like calcium, phosphorus, sodium.
- Extreme carbohydrate restriction can lead to hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog, which may last days to weeks
What impact does it have on our kidneys?
- Even the moderate increase in protein needs to be carefully monitored, especially in those who are already suffering from chronic kidney disease, as it could lead to kidney failure.
- One should get a thorough assessment and make sure they have normal kidney function before choosing this diet.
- This diet could lead to increased stress on the kidneys and result in kidney stones, as they are made to work overtime.
