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.
This just in: Saturated fat packs on more visceral fat than polyunsaturated ones, according to a recent Swedish study. When subjects ate 750 more calories daily for seven weeks—either in the form of palm oil (saturated) or sunflower oil (polyunsaturated)—the former gained more visceral fat while the latter gained more muscle mass and less body fat. Polyunsaturated fats can be found in nuts, seeds, and fish.
Obese people who consumed a tablespoon or two of vinegar daily for eight weeks showed significant decreases in body fat—particularly visceral fat—according to a 2009 Japanese study. "One theory is that the acetic acid in the vinegar produces proteins that burn up fat," explains Pamela Peeke, M.D., professor of medicine at the University of Maryland, author of Fight Fat After 40.
Stores of visceral fat, or belly fat that sit around the internal organs can increase a woman’s risk of diabetes and heart disease. Luckily, visceral fat is metabolically active and can be reduced quickly with a dedicated combination of diet, exercise and stress relief. You can lose belly fat fast by regulating stress hormones and boosting your metabolism.
5. Beware of buzzwords and marketing claims. Companies that make everything from soft drinks to processed foods may not always be telling the whole truth about how healthy their foods are, says Bowden. Their use of buzzwords like “organic” and “natural” might trip you up when you’re trying to make healthy choices. In a study published in 2014 in Food Studies: An Interdisciplinary Journal, researchers asked 318 college students to state whether they thought a food was healthy or unhealthy based on packaging images. When the image contained a health-food buzzword like “organic” or “whole grain,” participants rated the food as being healthier. Don’t judge a food by its packaging: Be sure to always read the nutrition label to get the whole story.
All meals are important, but breakfast is what helps you start your day on the right track. The best, heartiest breakfasts are ones that will fill you up, keep you satisfied, and stave off cravings later in the day. Aim to eat anywhere between 400 and 500 calories for your morning meal, and make sure you're including a source of lean protein plus filling fat (e.g., eggs, beans, unsweetened Greek yogurt, nuts, or nut butters) and fiber (veggies, fruit, or 100% whole grains). Starting your day with a blood sugar-stabilizing blend of nutrients will help you slim down without sacrifice.
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
Say cheese! Adding some extra calcium to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
Here’s a shocker: When a group of U.K. researchers told 30 women to avoid chocolate, then packed them into a room filled with the stuff; the women were much more likely to sneak a bite than individuals who hadn’t been given the order. Blame the allure of the forbidden: The more you tell yourself you can’t eat something you love, the more you’re going to want it.
As funny as it sounds, sleep deprivation may make you fat — and not just because you're susceptible to cases of the late-night munchies (although there's that too). There's tons of research that demonstrates getting less than the desired amount — about 7 hours — of sleep per night can slow down your metabolism. Plus, when you're awake for longer, you're naturally more likely to nosh. So don't skimp on your ZZZs, and you'll be rewarded with an extra edge when it comes to shedding pounds quickly.
