So, what should you eat if you’re trying to slim down?
“The best food someone on a diet should eat? The same foods they should eat when they’re not on a diet, but just less of them,” said Dr. Frank Sacks, a professor of cardiovascular disease prevention, also at Harvard’s School of Public Health.
All of the experts we spoke with agreed that those foods should include the staples of a “healthy” diet — fruits, vegetables, whole grains and healthy fats. These foods are important not only for achieving or maintaining a healthy body weight but also for good health in general.
In this article, we’ll highlight some of the most popular diets people turn to in order to lose weight, and explain what the science really says about how well they work. But before we delve into the diets, it’s important to break down the macronutrients of the foods we eat — carbohydrates, fats and protein — and the roles they play in the body. Of course, individual food can contain more than one more macronutrient.
