Low-Fat Ice Cream
No ice cream is nutritious, of course, but low-fat versions get viewed as better-for-you. They're not. "A lot of them aren't far off from regular ice cream in terms of calories per cup," Salge Blake says. "They take out some fat, but they add in sugar." That's bad, because more and more research shows that excess sugar – not fat – is the main culprit in weight gain. "The other issue with low-fat ice cream is people think they can eat more of it because it's 'healthier,'" Salge Blake says. "Same with frozen yogurt, since it's also lower in fat." To keep your portions in check, she recommends putting a pile of fresh strawberries or blueberries in your bowl first. Then use a half-cup of ice cream or frozen yogurt as a topping.
