However, if you are just starting a diet and exercising, you may lose more than that in your first week. "This period is perfectly normal to lose weight more than the ideal amount because it’s called Water Loss Phase" When you start consuming fewer calories than your body requires, your body begins to use the stored energy (glycogen) as fuel. The glycogen in your body is bound to water, so when you burn that glycogen as fuel, the water comes out with it. This is why we experience that amount of weight loss in the first week. Once our bodies get used to that, they start to stabilize at the ideal weight loss.
