The fiber found in nuts will keep you satiated, meaning you won’t be as easily induced to reach for the bread and butter, and you’ll be swapping out unhealthy fats for healthy ones. It’s a win-win!

The benefits of chowing down on whole fruits are clear, and eating an apple each day can help prevent metabolic syndrome, a disorder associated with abdominal fat, cardiovascular disease, and diabetes. The red or green fruits are a low-calorie, nutrient-dense source of fiber, which research has proven to be integral to reducing visceral fat. A study at Wake Forest Baptist Medical Center  found that for every 10-gram increase in soluble fiber eaten per day, visceral fat was reduced by 3.7 percent over five years.

_{Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.}
