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.
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 .
Think sweets are the enemy of weight loss success? Not so fast: dark chocolate might just be your best friend for weight loss (and that doesn't even include these other 5 Health Benefits of Eating Chocolate). Researchers at the University of Copenhagen fed healthy young men 100g of either milk or dark chocolate first thing in the morning, then had them rate their hunger level and fed them a meal of pizza two hours later. They found that the men who had dark chocolate were felt more satisfied after eating the chocolate, were less hungry, and ate less (17 percent fewer calories than the milk chocolate eaters) when offered pizza at their next meal.
While it’s often assumed that bread is off-limits when you’re trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn’t pack this healthy prebiotic fiber.
