At breakfast, go ahead and drink orange juice. But throughout the rest of the day, focus on water instead of juice or soda. The average American consumes an extra 245 calories a day from soft drinks. That’s nearly 90,000 calories a year—or 25 pounds! And research shows that despite the calories, sugary drinks don’t trigger a sense of fullness the way that food does.
“It can take 12 minutes or longer for the signal that you’ve started to eat to make its way to your brain,” says Mark S. Gold, M.D., of the McKnight Brain Institute at the University of Florida. Quick tips: Sip some water between every bite of food you eat, or at least eat more meals with friends or family members. You’ll be more likely to talk and therefore to eat more slowly.
You know that protein's essential for a slimmer you. But here's why protein really needs to play a prime roll on your plate: "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University. Insulin promotes fat storage—especially around your belly—and a diet high in protein may protect you against insulin resistance, says Aronne. In one study, obese women who followed a diet for eight weeks that was roughly 30 perecent protein, 40 percent carbs, and 30 percent fat lost significantly more fat—including visceral pudge—than women who stuck to a plan that was 16 percent protein, 55 percent carbs, and 26 percent fat.
“Most people who have been lean their whole lives have a much better understanding of proper portion size than people who are overweight,” says Deborah Riebe, Ph.D., a professor in the department of kinesiology at the University of Rhode Island. “If they go out to eat, they’re much more likely to ask for a doggie bag right away or to leave food on their plate rather than cleaning it up.”
