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.
Your parents weren’t kidding about how important veggies are for a healthy body. What they probably didn’t tell you, however, was that snacking on veggies is also one of the easiest ways to shed unwanted belly fat, too. According to a study published in the Journal of the Academy of Nutrition and Dietetics, opting for non-starchy veggies, like cauliflower, broccoli, and cucumber, as snacks helped overweight kids shed 17 percent of their visceral fat while improving their insulin sensitivity over a five-year period. Think snacking on veggies will leave you hungry? The 20 Most Filling Fruits and Veggies will have your belly satisfied in no time.
Don’t let extra hours lounging in bed stand between you and a flatter belly. 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 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.
Keep a calculator handy. To calculate your waist-to-hip ratio accurately, measure the narrowest point of your waist and the broadest part of your hip. Divide the values you obtained from the measurement and you have your ratio. The waist-to-hip ratio is a more accurate parameter to measure BMI. Those with a waist-to-hip ratio of 0.8 are susceptible to cardiovascular disease and stroke.
Doing crunches until the cows come home? Stop it! When you're down to your final inches of belly fat, the dreaded crunch won't be the exercise that finally reveals your six-pack. "You can't spot reduce," Jill says. Instead, she suggests doing functional exercises that use the muscles in your core—abdominals, back, pelvic, obliques—as well as other body parts. "These exercises use more muscles, so there is a higher rate of calorie burn while you are doing them," she says. Planks are her favorite functional exercise—they activate not just your core muscles but also your arm, leg, and butt muscles.

The conclusion? Intermittent fasting was just as effective for weight loss as daily calorie restriction. So if you struggle with daily food restriction, fasting might be an easier way to dial back the amount you’re eating without feeling completely deprived. Read more in-depth about how intermittent fasting works (and if you’ll be able to stick to it) here.
If you're having trouble sticking to a healthy eating plan, remind yourself of all the reasons you decided to start lose weight fast in the first place. “Think of your why's,” says Clark. “Healthy, family, personal. Our why's keep us on the right path more than the weight loss itself. People are truly sick of diets and appreciate the real food approach.”
Diet is a major part of the equation, but you can also lower your belly fat with a strategic workout plan. Since you can’t reduce fat in one area, you’ll have to focus on a full-body burn. The good news? That means you’ll be trim and lean all over, not just your mid-section. To torch fat, holistic nutritionist and certified personal trainer Ashley Walter recommends weight training and fasted exercise.
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.

In addition to making sure you don't wander in circles in the forest, the Instinct is a wellness tracker, keeping an eye on your steps, calories burned, stress levels (based on heart rate variability), and sleep quality. The Instinct has a 14 day battery life (or 16 hours with constant GPS monitoring), so you don't have to set it up on your nightstand every evening. Wear it to bed and it will track your REM sleep cycles and determine how restless you are during the night. There are even virtual fitness challenges that you enroll in from the Garmin Connect app to help keep you motivated.
Everyone’s body is different when it comes to digesting some gas-forming foods, but there are a few you should be wary of: It’s best to avoid beans and cruciferous veggies (think cabbage, Brussels sprouts, cauliflower, and broccoli) for a couple of days if you want to look slimmer. Choose lean proteins like chicken and fish or, if you’re vegetarian, go for small amounts of nuts and seeds for protein. Pair with non-gassy vegetables like asparagus, spinach, and cucumber to help prevent bloat.

The three major ingredients of a perfect Zero Belly Diet meal or snack are protein, fiber, and healthy fats, and all three can be found in abundance in a good trail mix. Sadly, most commercial mixes are made with extra oils, salt, and sugar. Mix up your own high-protein snacks from a selection of nuts, seeds, unsweetened dried fruit, and dark chocolate pieces. Make sure to include peanuts: they’re a top source of both genistein and resveratrol, two nutrients that help diminish the action of your fat-storage genes.
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.

Now, instead of just nagging you to close rings, your Series 4 will keep an eye on when your heart rate spikes and your motion is consistent with working out. Recently, when I thought I started my Nike Run Club run, the Apple Workout app buzzed me a quarter mile in, asking me if I was running. When I confirmed, it filled in the first part of my run and activated to log the rest. As someone who's always grumbling that if a run isn't recorded it didn't happen, that interaction was nothing short of revelatory.
