While many people turn to artificial sweeteners in a misguided attempt to whittle their waistlines, those fake sugars are likely to have the opposite effect. According to researchers at Yale, artificial sweeteners are actually linked with an increased risk of abdominal obesity and weight gain, possibly because they can trigger cravings for the real stuff and spike insulin levels in a similar fashion to real sugar.
To banish stubborn belly fat, you have to ramp up your workouts. In a study published in the journal Medicine and Science in Sports and Exercise, people who completed a high-intensity workout regimen lost more belly fat than those who followed a low-intensity plan. (In fact, the low-intensity exercises experienced no significant changes at all.) "You need to exercise at full intensity because the end goal is to burn more calories, and high intensity exercise does just that," says Natalie Jill, a San Diego, Calif.-based certified personal trainer. High intensity workouts mean you're going all out for as long as you can. If this sounds intimidating, think of it this way: you'll burn more calories in less time.
Women who wake up and go to bed at the same time each day have lower levels of body fat, according to a study of more than 300 women from Brigham Young University in Utah. Chaotic sleep habits cause your internal clock to go haywire, which in turn causes your body to secrete fat-storing hormones like cortisol. The sweet spot? Try not to stray an hour from your usual sleep pattern, the study authors say. More than a 90-minute difference in sleep and wake times were linked to more body fat. (Tossing and turning?

This is what's known as insulin resistance. Basically, when your body doesn't respond well to insulin, it actually makes more of the stuff, according to the National Institute of Diabetes and Digestive and Kidney Diseases. And that can lead to fat storage, especially around the middle of your body. That's where protein comes into play: A diet high in protein may protect you against insulin resistance, says Aronne.
Let's get the bad news out of the way first: unfortunately, there's no way to shrink specific parts of the body, which means you can't simply target belly fat. But that doesn't mean you can't work toward a trimmer waist. You just can't rely on crunches, planks, or sit-ups. Instead, it's all about putting yourself in a healthy calorie deficit, forming good habits, and doing full-body workouts that help you burn maximum calories. Here are some reliable tips to help you reach your goals.
By now you know to swap out regular yogurt for the Greek stuff and white bread for whole-wheat. But if you don't look closely, a product labeled "Greek" or "whole-wheat" may not be what it seems. A typical one-cup serving of plain Greek yogurt (like Fage 0%) provides 23 grams of protein and 9 grams of sugar, making it a smart choice. But another version of what looks like the same product can have over 18 grams of sugar. Not good, as the American Heart Association suggests women only eat 30 grams in an entire day. The same trickery goes for whole-wheat bread packages — some companies are loading it with high-fructose corn syrup, an unnatural additive that's 20 times sweeter than sugar and not recognized by the brain. Studies show that eating the stuff confuses your body's hormones so you don't realize when you're full, essentially forcing you to overeat when you thought you were making a healthy choice.
Stop treating your kitchen like an all-night diner and you’ll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you’re finished with dinner at night, shut the fridge and don’t look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the 40 Things Healthy Cooks Always Have in Their Kitchen are there waiting for you.
3. Exercise Ball Crunch: This is one of the most effective ways to strengthen and flatten abs. Studies show this exercise is 40% more effective than regular ab crunches as it targets smaller muscles for flat toned abs including the oblique’s for a small waist and the outermost muscles that your typical ab crunch may miss. To begin, lie down on the ball positioning it under the lower back. Place arms behind your head. Tighten your abs as you lift your torso off the ball while keeping the ball stable. Lower back down and repeat 15 times with 1-3 sets.
When you want to turn your diet around, don’t focus on the idea of restriction, Zeratsky says. Instead, think about the foods you can eat and how you can manage your hunger. “Eat foods that are more filling and have more water, like fruits and veggies, which will help your stomach respond to the weight to food,” she says. Plus, they’re low-cal and you still need that calorie deficit to drop belly fat.
