What Is A Ketogenic Diet?

A ketogenic diet is a low-carb and high-fat diet (somewhat similar to the Atkins diet). A keto diet consists of 80 % fat and little or no carbohydrates. The idea is to reduce the calories from carbohydrates and replace it with fats and proteins. This transforms the metabolism of the body from carbohydrate burning mechanism to fat burning. The staple foods generally consumed in a ketogenic diet include fish, meat, egg, fats and oils, dairy and green vegetables. Carbohydrate-rich foods like fruits, rice, pasta, sugar, and white bread are to be strictly avoided. Several studies are being carried out to assess the effectiveness of the ketogenic diet. The ketogenic diet promotes weight loss helps reverse type 2 diabetes and is also found useful against Alzheimer’s, epilepsy and cancer.

What Does ‘Keto’ Mean?

The word “keto” in a ketogenic diet points comes from ketone bodies that are produced when fat is burned. Ketones are an alternative source of fuel that provides energy to the body and brain when carbohydrates are in limited supply. On a ketogenic diet, the body runs on fat 24/7 and this helps burn stored fat in the body consequently promoting rapid weight loss. When the body starts producing ketone bodies, it enters a metabolic state known as ketosis. Ketosis can also be achieved on fasting but fasting is not a feasible option for the long term. The ketogenic diet, on the other hand, can be pursued indefinitely and provides a steady supply of energy, keeps you alert and focussed and promotes a feeling of fullness. Both protein and fat are known to promote satiety.

One study demonstrated that people lost 2.2 times more weight on a ketogenic diet than those on a calorie-restricted low-fat diet. It also improved their triglyceride and HDL cholesterol levels.

This can be attributed to its fat burning property. High body fat and weight are associated with increased risk of, metabolic syndrome, Prediabetes and type 2 diabetes. However, caution needs to be exercised and if you have diabetes especially type 1 diabetes than consulting your doctor before making such drastic changes in your diet is recommended.
