cut sugar out of your diet

By day two, things get interesting. Since glucose is running low, your body shifts gears and starts using stored fat for energy—a process called ketosis. This is when fat gets broken down into ketones, which become your new fuel source. Some people feel a sudden boost of energy and mental clarity, but others experience the dreaded “keto flu”—nausea, headaches, dizziness. This happens because your body is adjusting to burning fat instead of sugar. Staying hydrated and getting enough electrolytes can help ease these symptoms.
By the end of the first week, your taste buds start to reset. Foods that once tasted bland suddenly seem sweeter because your body isn’t overloaded with sugar anymore. Your cravings for processed sweets start to fade, and natural sugars—like those in fruit—taste more satisfying. Your metabolism is also improving, insulin sensitivity increases, and if you’ve been cutting sugar for weight loss, you might already see a difference, especially around your waistline.
Two weeks in, your energy levels become steady, and those mid-afternoon crashes are a thing of the past. Inflammation throughout your body decreases, which means your joints might ache less, your skin may start to clear up, and your risk of chronic diseases like heart disease and diabetes starts dropping. Your gut health improves too, as sugar feeds bad bacteria in the gut, so less sugar means a healthier digestive system.
