Keto flu is the condition that sets in when a person transits from a high-carbohydrate diet to a low-carbohydrate, high-fat diet also called the keto diet. The keto diet has gained increasing interest as more people look for natural ways to improve their health. The keto diet is touted to benefit health conditions such as being overweight or obese, epilepsy, PCOS, diabetes, autism, multiple sclerosis, non-alcoholic fatty liver disease, Alzheimer’s disease, and some cancers.
Ketosis is the name given to the process of breaking down fat into ketones; an alternative source of energy. In normal circumstances, ketosis occurs when there are no carbohydrates in the body due to fasting or starvation. Ketosis also occurs when a person switches to a keto diet.
The metabolic changes that follow may shock the body and manifest in the following 10 keto flu symptoms, among others.
Symptom #1: Cravings for Sugar
As a matter of reflex response, when you start adopting a keto diet as opposed to a normal, high-carbohydrate diet, your body can have real cravings for sugar. This is more of an initial resistant feeling that the body has due to the change in its source of energy.
Sugar is a quick and ready source of energy in normal circumstances. For this reason, a shift from it as a fuel source can prompt desire for sugar. The cravings can last for a few days from the onset of a keto diet until the body adjusts to the new fuel source.
