Some methods you can try include:
Control dietary intake: Reduce foods with high calorie, high fat and high sugar, and increase the intake of vegetables, fruits, whole grains and protein.
Cut down on snacks and desserts: These foods often provide empty calories and a lot of sugar, making it more difficult for you to control your weight.
Increase water intake: Drinking enough water can help you lose weight and improve your digestive system.
In short, it takes time and energy to lose weight, and healthy diet and moderate exercise are the best ways to achieve the goal.
