●Personalize your portions. If you’re a woman eating with a man, customize your portions to suit your body’s needs, says Sass. That might mean more veggies and smaller servings of protein and foods with starch and fat. For example, on burrito night, skip the tortilla in favor of a bed of greens, and stick to a piece of lean protein the size of a smartphone, a small scoop of a healthful starch such as brown rice and a dollop of guacamole.
Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
There is plenty that you can do to get even more out of your walks. Stephanie Cyr began her 102-pound weight loss journey by walking for an hour each night—but there was a catch. "I mapped out a 3-mile course that took me through the hills in my neighborhood," she says. Live in a flat area? Alternate 1 minute of super-fast walking with 1 minute of slower walking for a calorie-torching interval routine.
Eat Breakfast Every Day. One habit that's common to many people who have lost weight and kept it off is eating breakfast every day. "Many people think skipping breakfast is a great way to cut calories, but they usually end up eating more throughout the day, says Elizabeth Ward, MS, RD, author of The Pocket Idiot's Guide to the New Food Pyramids. "Studies show people who eat breakfast have lower BMIs than breakfast-skippers and perform better, whether at school or in the boardroom." Try a bowl of whole-grain cereal topped with fruit and low-fat dairy for a quick and nutritious start to your day.
