People who severely cut their sugar intake may experience withdrawal symptoms such as headaches, cravings, and mood swings. These should be gone in a few days or weeks. If you're still feeling these effects after binging or using drugs to beat your sugar habit, it's time for change. Sugar withdrawal is a popular term used to describe the unpleasant physical and mental effects that occur when someone stops consuming sugar abruptly or drastically reduces its amount consumed per day. The most common symptom of sugar withdrawal is a craving for something sweet. Other possible symptoms include irritability, fatigue, headache, diarrhea, and muscle aches. In some cases, people who eliminate sugar from their diet for several days or weeks at a time report feeling better than they have in years despite having normal or even low blood sugar levels during this time. The idea of sugar withdrawal has been popularized through books and websites that promote quitting sugar all together or cutting down on its consumption. Although experts agree that severe dietary changes can lead to nutritional deficiencies and cause people to feel weak or sick, there is no scientific evidence that links sugar withdrawal to any adverse effects. In fact, many people report feeling better after removing sugar from their diets.
