According to the United States Department of Agriculture, a half-cup of granola has anywhere between 200 and 300 calories, 12 to 16 grams of sugar, 3 to 15 grams of fat (depending on low-fat options), and nearly 40 grams of carbs. Plus, granola is usually mixed with something, like yogurt or fruit, which only increases its caloric value. “Although you may think starting your day with a bowl of granola is the healthy thing to do, the calories can easily add up to over 600 calories, just at breakfast,” says Toby Amidor, MS, RD nutrition expert and author of the Greek Yogurt Kitchen.
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. What that means for you: You're less likely to go back for seconds or thirds. Plus, it'll help you relax post meal so you won't be tempted by stress-induced grazing that can rack up calories, quickly.
“Under normal conditions, humans absorb only about 80% of the nutrients from the food they eat,” says A. Roberto Frisancho, Ph.D., a weight-loss researcher at the University of Michigan. But, he says, when the body is deprived of nourishment, it becomes a super-efficient machine, pulling what nutrients it can from whatever food is consumed. Start eating again normally and your body may not catch up; instead it will continue to store food as fat.
One of the biggest mistakes women make when trying to figure out how to lose belly fat: too many crunches, too little cardio. No matter how toned your abs are, your belly won't look flat until you get rid of the layer of fat on top of them, says Jessica Smith, a certified personal trainer and star of fitness DVDs. For that, you need to rev your calorie burn. Interval training, in which you alternate high-intensity bursts of activity with easier bouts, has been shown to zap more belly fat than steady-paced moderate workouts.
Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.
