What is a keto diet?

A ketogenic diet or in short keto diet is a low in carbs, adequate proteins and high in fat diet that’s used to treat diseases and fight obesity. The diet forces the body to use fat for energy other than carbs. In normal circumstances, the carbohydrates contained in the food we eat is turned into glucose which is then transported around the body. However, if there are little carbohydrates in the body, then the liver converts fat into fatty acids and ketones. The ketone bodies then replace glucose as an energy source for the brain.

To sum up, the process by which the body enters a metabolic state and turns fat into ketones is called ketosis. Ketones are molecules that can supply energy to the brain.

A few weeks while on the keto diet, the body and brain become efficient in burning fat for energy instead of carbs and this leads to weight loss.  The keto diet also lowers insulin levels in the body. These are the main reasons for the keto diet.

The keto diet involves dropping off most of the grains, rice, sweet potatoes, cereals, corn, fruits nearly all foods rich in carbohydrates. Then foods high in fat are adapted and some of them include fish, meat, pork, eggs, cream, avocados, oils, nuts, and low-carb vegetables.
