Physical activity helps burn abdominal fat. “One of the biggest benefits of exercise is that you get a lot of bang for your buck on body composition,” Stewart says. Exercise seems to work off belly fat in particular because it reduces circulating levels of insulin —which would otherwise signal the body to hang on to fat—and causes the liver to use up fatty acids, especially those nearby visceral fat deposits, he says.
We’re continuing to learn that shortchanging our sleep — even for just one night — can lead to less healthy food choices the next day. The latest study took a look at subjects’ MRI scans after a night of sound sleep and again after a night of sleep deprivation. The MRI scans showed that sleep deprivation activates an area of the brain that makes you view food as more desirable. In other words, it prompts cravings. This adds to other evidence showing that insufficient sleep increases hunger while also making us less likely to stay active. Taken all together, it means that a healthier sleep situation can encourage a healthier weight.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
If you're specifically looking to target your belly, we have some bad news: you can't spot-target fat loss. That means you can do crunches or planks all day long, but you won't specifically burn belly fat. Instead, you can lose body fat overall, including from your belly. And by avoiding certain belly-bloating foods and with some strategic exercise, you will inevitably see results in your belly.
In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
