You know the drill: Replace refined, overly processed foods with more natural, whole foods. Sure, all foods fit, but they don’t all fit equally. Here’s why: Every time you eat, your metabolism increases as your body works to process your meal. Studies that compare the metabolic boost of calorie-matched whole foods to processed ones find that your body can burn up to 50 percent more calories after a meal made with more real food ingredients compared to a similar meal made with more processed fare. The fact is, your body has to work harder to break down whole foods in order to grab the raw materials it needs so if you exist on a lot of packaged foods and fast foods (think: chips, donuts and drive-thru fare), it’s going to be tougher to lose weight and keep those pounds from coming back.
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
Make sure that you don't get hungry by eating small portions throughout the day at regular intervals. Between your meals, eat a 150-calorie snack to keep your metabolism burning and to stave off hunger. Be sure that you don't eat a fattening snack such as sweets or crisps. When you're hungry, your body conserves calories and slows down your metabolic processes.
In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
