Cleansing can help you lose weight in several ways. First, if you eat fewer calories than usual, your body will burn more fat for energy. Second, eating more fiber will make you feel full faster and prevent overeating later. Third, by increasing your protein intake and decreasing your sugar intake (or eliminating it altogether), you will be giving your body what it needs to function optimally – and that means burning more calories at rest! Finally, drinking plenty of water helps flush toxins out of your system while also making sure that none of the food or drink that passes through your digestive system gets absorbed into your bloodstream as waste material; This means less fat storage overall.
