Sugar Withdrawal

By days 10 to 13, sugar cravings are expected to be gone as the body accesses stored fat for fuel. The article states that the average withdrawal phase lasts 2 to 4 days for most adults. High-glycemic foods are reported to activate the nucleus accumbens more intensely than low-glycemic foods. Sugar withdrawal involves dopamine demand while dopamine receptors are downgraded. By days 5 to 7, dopamine begins to upregulate and dopamine receptors begin resetting. Headaches, fatigue, and irritability during days 2 to 3 are described as neurochemical adjustments. Resisting cravings can raise cortisol and create internal pressure through adrenaline and cortisol. Cravings during the two-week hold can feel like physiological needs, but the article frames them as recalibration signals with an endpoint.
