I'll tell you what I've always insisted on:
1, control calories and fat, always be careful about the calories of food, reduce some fat in your diet, and increase some fish and poultry.
2, the diet should be light and 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.
4, a balanced diet, a balanced diet every day as planned, while paying attention to timing, do not overeat. To slow down the time for eating, the time for eating a meal should be no less than 20 minutes.
