One small diet change is all you need to make a big difference. Fiber, it is your friend. A new study found that subjects who added 7 grams of fiber to their diet, instead of eating a more complex diet, had similar weight loss. The "high maintenance" dieters only lost 4 more pounds than the fiber group. Aim for 38g fiber a day from “natural high-fiber foods,” says the study’s Yunsheng Ma, Ph.D. So load up on your lentils, apples, broccoli, chia, all your favourite high fiber foods and you'll be trimmer in no time!
