This naturally sweet winter squash boasts one of the highest fiber counts of all the veggies, ringing in at a whopping 9 grams per cup. Promoting feelings of fullness—and thus staving off overeating so you can burn, rather than gain, fat—with satiating fiber isn’t the only way you’ll target that turkey neck. That’s because acorn squash is also an excellent source of vitamin C, a micronutrient that your body uses to decrease levels of the fat-storing hormone cortisol and boost the fat-burning effects of exercise, according to Arizona State University researchers.
Carbs are not the enemy. Not whole-grain carbs, that is. People who ate three or more daily servings of whole grains (such as oats) had 10 percent less belly fat than people who ate the same amount of calories from processed white carbs (bread, rice, pasta), according to a Tufts University study. It’s theorized that this is due to whole grains’ high fiber and slow-burn properties, which keep you satiated longer.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, a study published in Diabetes Care revealed that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.
Red is one of the best colors for weight loss. That’s because the color is due to higher levels of nutrients called flavonoids—particularly anthocyanins—which calm the action of fat-storage genes, according to Oxidative Medicine and Cellular Longevity research. In fact, red-bellied stone fruits like plums boast phenolic compounds that have been shown to “turn off” fat genes. Plus, their pectin—a gelatin-like type of fiber found in the cell walls of fruits—limits the amount of fat your cells can absorb, as shown by a Nutrition & Metabolism study.
Don’t let extra hours lounging in bed stand between you and a flatter stomach. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One Obesity study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans-fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
