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.
In general, a good weight-loss goal is to lose 0.5-1.0 percent of your body weight each week. If your weight-loss stalls, it's because your body has learned how to function on fewer daily calories. To reignite fat loss, reduce your current calorie intake by 15-20 percent. (In the example above, the person could consume 2,000 calories a day. To lose weight, they would have to reduce that by 300-400 calories a day.)
Interval Training: A great way to incorporate high-intensity training without doing it continuously is by doing intervals. Alternate a hard segment (e.g., running at a fast pace for 30 to 60 seconds) with a recovery segment (e.g., walking for one to two minutes). Repeat this series for the length of the workout, usually around 20 to 30 minutes. A 30-60-90 interval workout is a good example of this kind of high-intensity workout.
”In many ways, body fat is the same as food intake, it’s all available energy, and this is reflected in the fact that adipose tissue produces leptin. You can increase fat by 10-20g, and that’s another 90-180 calories your body “sees”, but gain 1lb of body fat and you’ve got 3500kcals that your body is seeing now…so yeah, changes in body fat can make much larger impacts than what you consume…that’s why I shake my head when guys freak out about going from 50g to 45g of dietary fat….really, you think the 45 calories per day is what is going to kill your libido, not the fact that you lost 10lbs (35,000kcals) of fat? ”
Grazing is a surprisingly good idea because it helps you avoid metabolic slowdown. "Your body will be tricked into thinking it's constantly eating, so it will never slow your metabolism down," explains Bauer. Aim for five small meals (200 to 500 calories) a day rather than three large ones. Also try not to go more than four hours without eating — if you eat breakfast at 7am, for example, have a snack at 10am, lunch at noon, another snack at 3pm and dinner at 7pm.
