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.
Thanks to the hormone estrogen, the female body likes to hold on to fat, too. A study in Obesity Reviews shows that women store fat more efficiently than men in an effort to prepare the body for pregnancy. But while it seems like women may have drawn the short-end of the stick, the stereotypical pear-shape is actually considered healthier than boasting a beer gut, because belly fat is a red flag when it comes to your health. “Visceral fat is associated with increased risk of diabetes, high blood pressure and metabolic syndrome,” says Harris-Pincus.
If you want to lose weight you should start by avoiding sugar and starch (like bread, pasta and potatoes). This is an old idea: For 150 years or more there have been a huge number of weight-loss diets based on eating fewer carbs. What’s new is that dozens of modern scientific studies have proven that, yes, low carb is the most effective way to lose weight.
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
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.
Still try to consume as many veggies and fruits as possible. Even if you don't enjoy carrots or salads, do what it takes to get yourself to eat them (e.g. plug your nose and chase bites of veggies with water like you did when you took medicine as a kid). You really have to try everything. Also, stick with the lean meats like fish or poultry. If you don't eat a healthy diet, you'll have to exercise more.
3. Be realistic about which habits need to go. "When I was heavy, I'd eat French fries every single day, plus carbs at almost every meal—like a sandwich for lunch or bread with pasta for dinner. A diet so heavy in fried food and carbs just isn't conducive to weight loss. To lose the weight, I went from three large meals a day to six small meals, mostly made of fresh vegetable salads with lean meats and nuts. And no more bread!"
2. Eat five times a day. Yes, you heard that right. Dr. Ziltzer recommends eating three meals and two snacks a day, with the snacks limited to fewer than 200 calories each. Choose high-protein bites that will leave you satisfied for two to three hours, such as yogurt, beef jerky, boiled eggs, protein shakes, deli meats, and snack bars low in sugar. And don't forget to eat breakfast, which has been shown to help boost weight loss .
Sure, you certainly need to drink plenty of water to help expedite the process of ridding your body of excess sodium, you can (and should!) also consume high-water content foods. Reach for cucumbers, tomatoes, watermelon, asparagus, grapes, celery, artichokes, pineapple, and cranberries — all of which contain diuretic properties that will also help you stay full due to their higher fiber content.
Sure, ketchup is tasty, but it’s also a serious saboteur when it comes your weight loss efforts. Ketchup is loaded with sugar — up to four grams per tablespoon — and bears little nutritional resemblance to the fruit from which it’s derived. Luckily, swapping out your ketchup for salsa can help you shave off that belly fat fast. Fresh tomatoes, like those used in salsa, are loaded with lycopene, which a study conducted at China Medical University in Taiwan links to reductions in both overall fat and waist circumference. If you like your salsa spicy, all the better; the capsaicin in hot peppers, like jalapeños and chipotles, can boost your metabolism, too.
