The best way to lose weight quickly: First, change the food structure. Changing the food structure is a necessary condition for slimming. Replacing high-fat foods with fruits, grains and vegetables can help you lose weight faster, healthier and more effectively. Second, eat less. You can't eat three meals a day, but the calorie intake of each meal should be strictly controlled, and you can eat seven or eight points full. The calorie intake of three meals a day should not exceed 2000 calories, and the calorie intake ratio of three meals in the morning, noon and evening should be 4:4:2. Third, don't eat before going to bed. Eating high-sugar and high-fat foods before going to bed will reduce calorie consumption and increase fat storage during sleep. Fourth, we should exercise more and create more opportunities for exercise. Insist on exercise, and ensure aerobic exercise for more than 30 minutes three to five times a week.
