5 Things to Know About Losing Belly Fat, Straight From a VS Angel Trainer

We know, we know — easier said than done. But stress is one of the main reasons we hold onto belly fat, according to Gelson. "Proper relaxation and meditation can allow our stomachs to be less bloated or have less puff," he said. "It's imperative that you give yourself a chance to stretch, relax, and meditate 10-15 minutes daily."

This tip is all about easing the stress you put on your digestive system. Gelson recommended eating five smaller meals a day and making sure to finish eating by 8 p.m. "This is gentler on digestion, because your stomach is never too full and this helps with relaxation while sleeping," he explained.

Gelson recommends drinking a gallon of water per day. "Many of us are dehydrated throughout the day because we don't drink enough water," he said. When you drink enough water it helps clean out your system and flatten your belly, he explains. Also, sip your water — don't gulp it, he added.
