Fruit and vegetables are low in calories and nutrient dense, which means they are packed with vitamins, minerals, antioxidants, and fiber. Focus on eating the recommended daily amount of at least five servings of fruit and vegetables and it will naturally fill you up and help you cut back on unhealthy foods.

These options will help you prevent cravings and keep you full straight through your usual afternoon snack.
