Protein...

 

To reduce visceral fat, add a protein supplement to your healthy, balanced diet. Several studies have associated protein consumption with the loss of visceral fat. 

Researchers found that a test group that took a protein supplement along with a mildly calorie-restricted diet lost more visceral fat than a group that took a placebo.

In addition, the test group's gut microbiota was activated by the protein supplement. Some studies have connected healthy gut microbiota to the loss of visceral fat—regardless of diet.

Feel fuller sooner, it might help you reduce the number of calories you consume, particularly from processed foods and snacks that are associated with higher levels of visceral fat. 

Consuming protein also seems to reduce levels of ghrelin, the hormone that increases appetite.
It's also believed that protein boosts your metabolism, enabling you to burn more calories 24 hours a day. What's more, protein can help you build lean muscle, giving your metabolism an additional boost as you burn more calories at rest.
