When you're used to eating sugar regularly and suddenly stop, you may feel sugar withdrawal symptoms. These may include fatigue and cravings, but some people may experience other symptoms, such as changes in mood and sleep. If you're looking to reduce how much sugar you eat, it's helpful to be aware of potential withdrawal symptoms.

This article discusses some common physical and mental signs and symptoms of sugar withdrawal.

Sugar withdrawal symptoms may last anywhere from a few days to several weeks and can vary significantly among people. Withdrawal symptoms may depend on how quickly you reduce your intake and how quickly your body's tolerance adapts to eating less sugar.

Giving up too many carbs can put you in a metabolic state called ketosis. It occurs when your body begins to burn fat for energy due to a limited supply of sugar in your blood (glucose). Glucose is your body's primary source of energy. Without it, your body begins to use fat instead of carbohydrates for fuel Some people describe ketosis as feeling like they have the flu.

It may just mean that your body needs a different approach to reducing glucose and carbohydrate intake that is more sustainable and doesn't have severe side effects . It can be helpful to speak to a registered dietitian knowledgeable about adapting to a keto and low-sugar diet.
