How could diet affect obesity?

Diet is central to both the development and the management of obesity and the mainstay of dietary interventions for treating obesity involves calorie restriction. A commonly used approach includes limiting daily calorie intake to 1200–1500 kilocalories (calories adjusted to a person’s weight) for women and 1500–1800 kilocalories for men. Another approach is eating a diet with a 500–750 kilocalorie deficit. Many different types of diets have been used for weight loss; the diet that will be most beneficial over time will vary from person to person, and adherence to the diet is crucial.^[1]
