Routinely squeaking by on five hours or less per night increases visceral fat levels, according to a 2010 Wake Forest University study. What’s more, after analyzing 28 different studies, UK researchers found that people who slept 5.5 hours or less per night ate an extra 385 calories the day after compared to those who snoozed for at least 7 to 12 hours. On top of that, they preferred to munch on fatty foods full of empty calories, like chips.
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.
Intermittent fasting has blown up in the past year, but scientists are just starting to figure out how it can help you lose weight. In one study from the University of Illinois at Chicago, researchers compared obese people in a traditional weight loss group and fasting group. For the experiment, the calorie-restricted group simply reduced the amount of calories they ate by 25 percent each day. The fasting group, however, alternated days: they ate 25 percent of the calories they needed one day between 12 and 2 p.m., and then had feast days the next, where they ate 125 percent of their required calories.
I put theory into practice. In 2003, I had once again grown out of my belt. I wasn't grossly overweight: 205 pounds in a six-foot, one-inch body. That wouldn't be bad for a football player, but I'm 59 years old, and the excess pounds weren't in muscle. I had gained a pound a year for several decades. I felt heavy and old. I decided to try conservation of energy. I gave up lunch and snacks.
If you're among the 30% of Americans who sleep less than six hours a night, here's one simple way to whittle your waistline: catch more Zs. A 16-year study of almost 70,000 women found that those who slept five hours or less a night were 30% more likely to gain 30 or more pounds than those who slept 7 hours. The National Institutes of Health suggest adults sleep seven to eight hours a night.
Now you know that your dinnertime TV show and dishware affect how much you eat—but did you know that your environment has an even greater impact on your noshing habits? The typical American buys and eats more than 80 percent of their food within five miles of their homes—a.k.a. your food radius—according to Brian Wansink, Ph.D., director of Cornell University's Food and Brand Lab. In his book, Slim By Design: Mindless Eating Solutions, Wansink talks about various studies he's done over the course of his research career that show how your food environment dictates your eating habits.
Studies have found that overweight people who ate a moderate-fat diet containing almonds lost more weight than a control group that didn’t eat nuts. Snacking once or twice a day is one of the ways to lose weight that helps stave off hunger and keeps your metabolism stoked. You can also pack up baby carrots or your own trail mix with the healthiest nuts you can eat, plus raisins, seeds, and dried fruit. Here are 30 healthy snacks that can help you lose weight.
The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.
“Most people who have been lean their whole lives have a much better understanding of proper portion size than people who are overweight,” says Deborah Riebe, Ph.D., a professor in the department of kinesiology at the University of Rhode Island. “If they go out to eat, they’re much more likely to ask for a doggie bag right away or to leave food on their plate rather than cleaning it up.”
If you run for an hour, you'll lose that ounce of fat and also a pound or two of water. By the next day, when you've replenished the water, you might think, 'the weight came right back!' But you'd be wrong -- you really did lose an ounce. It is hard to notice, unless you keep running every day for a month or more, and don't reward yourself after each run with a cookie.
There's one thing to like about visceral fat: It yields fairly easily to aerobic exercise. Running, biking, or swimming—basically anything that gets your heart rate up—wins over resistance training when it comes to getting rid of the stuff. A recent study from Duke University found that jogging the equivalent of 12 miles a week is enough to melt belly fat.
What happens if you fast for a day? What happens if you don't eat for a day? While most people will feel hungry and possibly tired, there is also a range of other effects. In this article, learn about how the body starts to burn fat for energy and whether fasting for 24 hours can be a good weight loss tool. We also investigate the possible risks. Read now
