What is a keto diet, how could it help us and types?


The name keto represents the ketogenic diet and ketogenic is a term for a low-carb diet. The main idea of a keto diet is to get more calories from protein and fat and less from carbohydrates.

Let’s discuss more.

When we have more carbohydrates food, our bodies will produce glucose and insulin.

Glucose: It is a source of energy and the easiest molecule for the body to convert and use it as energy.

Insulin: It is produced to process glucose by taking it around the body.  

Since the glucose is used for energy so there is no need for using the fats so they get stored. If we have a high-carbohydrate diet, it will be enough to produce energy for our body. By lowering the carbohydrates in the diet, the body will be induced into a state named as ketosis.

Ketosis is a natural process in the body to survive whenever we had a low intake food. At this time ketosis is produced by breaking down fats from the liver.

Keto diet forces us to this metabolic state. We do it by starving carbohydrates but not through starving calories. when we take more fats by taken away the carbohydrates in the diet will make use of ketosis more to produce energy by burning fats.

Keto diet helps us to reduce weight, controls blood sugar, improves mental health, maintains blood pressure and controls cholesterol, etc.
