Drinking Besunyen slimming tea has no obvious slimming effect and has great side effects. Please don't lose weight blindly, it will ruin your health. The real way to lose weight is to adhere to three principles: 1. A reasonable diet (seven full meals). 2. Get enough sleep (how much fat you burn when you sleep deeply at night). 3. Moderate aerobic exercise (burning calories in the first seven minutes and burning fat later).
