Is Your Diet Making You Fat?
The surprising mistakes that are costing you big time in your efforts to slim down
Over-doing it on "approved" foods
How it hurts: The tenets of the Paleo diet are this: Focus on eating meats, veggies, nuts, seeds, with a little fruit and starch added in. But just because it's a diet with an emphasis on whole foods doesn't give you an excuse for a free-for-all. "Anything you eat in excess of what your body needs to support a given weight winds up feeding fat cells -- even lean protein," says Sass.
The most common culprit of sneaky weight gain? Nuts. Though they are heart-healthy, they're also calorically dense, so, before you know it, you've eaten half a day's worth of calories, says Sheth.
The Fix: Stick to one serving a day, and make sure that it's an actual serving: about 22 almonds, 16 cashews or 14 walnut halves.
