4. Focus on fiber
Another study, also published in the journal ‘Obesity, showed that belly fat increases less quickly if you pay special attention to your fiber intake.
The researchers increased the daily intake of soluble fiber by 10 grams in the study participants to find out. The result: the rate at which abdominal fat accumulated over five years dropped by 4 percent.
The reason: Dietary fiber slows digestion and makes you feel fuller longer. You can get the extra 10 grams with, for example, half an avocado, 3/4 cup of black beans, 3/4 cup of oatmeal, and a red apple.
