Green tea isn't known only for its cancer-fighting benefits: It may help boost your metabolism, too. People who took green-tea extract three times a day saw their metabolic rate increase by about 4 percent, according to a study published in the American Journal of Clinical Nutrition. (Translation: You could burn an extra 60 calories a day, which equals about six pounds a year!) It may be because green tea contains catechins, which increase levels of the metabolism-speeding brain chemical norepinephrine, says Joy Bauer, a New York City nutritionist and author of Cooking with Joy.

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.
All animal proteins are also a good source of tryptophan, which is a precursor to the neurotransmitter serotonin. “If you struggle with mood or stress, it’s important to boost the production of serotonin to stabilize your mood, curb emotional eating, and keep stress-induced snacking at bay," especially when you’re trying to lose weight, says Cording. But when it comes to portions, opt for a 100 gram serving, which is about the size of a deck of cards, for reference.
Think of the typical toppings on your baked potato -- butter, sour cream, maybe cheese and bacon bits. If you substitute a sweet potato, you might not need any of that. Baked sweet potatoes are so full of flavor, they don't need a lot, unless you want to try a sprinkle of cinnamon. This can save you loads of calories. As a bonus, sweet potatoes are packed with potassium, beta-carotene, vitamin C, and fiber.
What about the calories? When they avoided eating between the hours of 7 p.m. to 6 a.m., participants reduced their daily calorie intake by an average of 238 calories. Which helps to explain the weight loss of almost half a pound a week. Interestingly, their intake of fat decreased significantly while protein and carbohydrate decreased at a more conservative rate. This leads one to believe that the subjects were not eating grilled chicken and broccoli late at night. No, their usual late-night snacks were much higher in fat.
1. Boost your metabolism throughout the day: Your BMR regulates how many calories you burn at rest and the more you move, the higher your BMR, and the more you’ll burn when standing still. Small efforts like taking the stairs, walking to pick up lunch, even playing pool with the guys during happy hour can all jumpstart your metabolism.

Diet drinks can have a kind of mental placebo effect, making you feel like it’s OK to indulge because you “saved” all those liquid calories. And research shows that your body may be tricked too: People who chug one or more diet drinks a day are more likely to be overweight—not less. Can the soft drinks, whether the sugar in them is real or a substitute. Find out 30 other tiny diet changes that can help you lose weight.
Good sleep hygiene can help. “Our ancestors needed to sleep when it was dark, quiet, and cool, Gillespie says. “That meant it was safe.” Despite technological advancements like heat and air conditioning, our bodies still crave those cave-like conditions. Draw the blinds, use a white noise generator, and keep the thermostat set between 63 and 68 degrees.

1. Don’t starve yourself: Cortisol—that stress hormone that causes your body to store more fat—is elevated from circumstances of high stress, including extreme dieting, Seedman says. “If you start dropping calories excessively, your body goes into starvation mode and it becomes stressed. You’re in caloric deprivation, but that elevated cortisol causes you to gain body fat in your stomach—it’s a vicious cycle,” he adds.
