High levels of fruits, vegetables, and beans promote weight loss because they are low in calories and high in volume and critically important nutrients. Because they fill you up without loading you up with fat and calories, produce leaves less room for more fattening and less nutritious foods. Studies show eating a lot of fruits and veggies also helps turn off cravings for processed food and helps reduce binging on fattening foods. Unlike crash diets that rob your body of essential nutrients, juicing promotes safe and healthful weight loss.
