If you’re serious about losing belly fat, you’ll need to watch your alcohol intake. Research published in the Journal of Nutrition shows that people who drink alcohol, but don’t binge drink have less belly fat than people who drink occasionally, but heavily (i.e. binge drinkers). Large volumes of alcohol are thought to elevate cortisol, which increases belly fat. In other words, don’t save up for a big night out. Studies also suggest that light to moderate wine drinking (i.e. one glass of wine) can help protect against belly fat.
