The reason it is called the keto flu is that the symptoms of this problem are similar to the common flu. When carb intake is reduced, the body burns out ketones instead of glucose, and ketones are by-products of broken-down fat. Ketones are the main source of weight loss and energy in ketogenic diets. Normally, energy is obtained from carbohydrates, and when there is a very little amount of carbs in the body, fat is burnt, which will produce energy.

When someone starves or fasts, the fat is burnt and turns into energy, and this process is called ketosis. This sudden change in the carb intake will lead to withdrawal symptoms, and the symptoms can be similar to the one of alcohol, drug, and caffeine withdrawal, or from any addictive substance.
