The best, fastest, most fundamental, healthiest, safest, most environmentally friendly, most thorough, most harmless and without any side effects is to control the diet reasonably:

1, control calories and fat. Always pay attention to the calories of food, reduce some fat in the diet and increase some fish and poultry.

2, the diet should be light. Eat less salt. The more salty you eat, the more you want to eat. Eat less processed food with sauce. These foods are rich in sugar, salt and flour, which will increase your calories.

3, often eat fruits and vegetables. Eat some fiber-rich fruits, vegetables and whole wheat bread in moderation.
