Ketogenic diet or Keto diet is one of the diet plans for losing weight. Contrary to other diets, however, a ketogenic diet plan makes you consume fewer proteins and more fat. This diet works on the biological principle of Ketosis.
We all know that the primary fuel of our body is glucose which we get from proteins and carbohydrates. And when our body has the deficiency of glucose, our liver produces another type of cells, called Ketones, which supply energy to the body in the absence of glucose. The accumulation of Ketones in blood is called Ketosis.

So to prevent the creation of glucose in the body, the ketogenic diet prohibits carbohydrate-rich foods. Thus, if you are following a ketogenic diet, you are bound to take 70-80% of fat, 5-10% of carbohydrates, 10-20% proteins. The intake of protein is minimized to prevent Ketosis.
Since the 20th century, the ketogenic diet is seen as a good weight loss strategy. The diet is used to treat specific medical conditions. When it was introduced in the 19th century, it used to control diabetes. Later, the diet was used for the treatment of epilepsy. Then it started being used in cancer, diabetes, polycystic ovary syndrome, Alzheimer’s disease, etc.
For quite a long time, the ketogenic diet was assumed to be beneficial for metabolic changes. It was helpful for biological problems such as insulin resistance, high blood pressure, elevated cholesterol, triglycerides, and other diseases due to excessive weight.
Things, however, are not just positive with the ketogenic diet. The diet, in the long term, causes hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog. It can also be the reason for kidney stones, osteoporosis, increased blood levels of uric acid, and various nutrient deficiencies.
