When Tufts University researchers studied the waistlines and diets of 459 people, they found that even in men of similar age and activity level, those who ate white bread frequently weighed more than those who didn’t. “The calories from white bread and refined grains just seem to settle at the waistline more than calories from other foods,” says Katherine Tucker, Ph.D., the study author.
Lack of sleep doesn't just cause undereye bags, a grouchy mood, and an insane craving for coffee; studies on sleep continually show that a lack of sleep means a bigger appetite and BMI. For example, in a 2002 study of over one million people, scientists found a direct correlation between less sleep and a higher BMI for anything under seven hours/night. More recently, a 2016 study published in the journal SLEEP found that sleep-deprived people reported more hunger and had a harder time resisting unhealthy snacks—even when they had had a huge meal (that supplied 90 percent of their daily caloric intake) only two hours prior. The scientists said that sleep deprivation activated a similar system that's targeted by the active ingredient in marijuana and enhances the desire for food.
Losing weight is hard—it takes a lot of sweat and starvation, right? Well, actually, it doesn't have to. While hitting the gym and eating healthy is the surefire way to be your healthiest, fittest self, sometimes you need to start small or build up some extra credit to get over that plateau. That's where these 10 little tricks (backed by science!) will come in handy to help you drop pounds without even trying.
When your body is low on calcium, it produces a hormone that signals the body to store visceral fat. Meeting your recommended daily calcium needs (that’s 1,000 milligrams for adults) can help reduce levels of this hormone. And a recent study published in Obesity Research found that calcium from dairy has a stronger effect than calcium from other sources. I recommend eating low-fat Greek yogurt as a daily snack (just six ounces contain about 20 percent of your recommended dietary allowance for calcium), though any low-fat dairy will do.
“Trans fats don’t occur in nature, so our bodies weren’t designed to metabolize them,” says Schoffro Cook. “That means they can’t be properly digested, throwing off blood-sugar levels and contributing to obesity.” A six-year study found that a high-trans-fat diet that included foods like margarine led to a 33 percent increase in tummy fat. By contrast, she says, “coconut oil speeds fat-burning.”
"Refined grains like white bread, crackers, and chips, as well as refined sugars in sweetened drinks and desserts increase inflammation in our bodies," says Patton. "Belly fat is associated with inflammation, so eating too many processed foods will hinder your ability to lose belly fat." Natural foods like fruits, vegetables, and whole grains are full of antioxidants, which have anti-inflammatory properties and may therefore actually prevent belly fat, Patton says.
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. What that means for you: You're less likely to go back for seconds or thirds. Plus, it'll help you relax post meal so you won't be tempted by stress-induced grazing that can rack up calories, quickly.
Try this interval-training trick on the elliptical trainer: Ride for 30 seconds as fast as you can, then immediately reverse your direction and ride for 30 additional seconds just as fast in the opposite direction. Rest 60 seconds, and repeat. The force of stopping your momentum, as well as going from a dead stop to full speed twice in the same interval, will give your fat-burning efforts a massive boost, says Alwyn Cosgrove, C.S.C.S.
Remember, belly fat is not just troublesome because it makes you unhappy when you look in the mirror. The excess weight around your middle that increases with every passing year can raise your risk of type 2 diabetes, heart disease, dementia, and more. But if you're wondering what you can do to prevent that, these tricks to lose belly fat fast can help a lot.
