"America has been trying to follow a low-calorie, low-fat diet for 40 years, and where has that gotten us? To being one of the heaviest countries in the world," says David Ludwig, M.D., Ph.D., obesity expert and author of Always Hungry. Think about it: "The problem is when you cut back on calories like that, your body tries to fight back with increased hunger and a slower metabolism because it thinks it's going into starvation mode," he says. Meanwhile, you eventually eat again to satiate the hunger pangs, and likely eat more because, well, you're insanely hungry. But your metabolism is still operating on that low level, so calories don't get burned fast enough and they get stored as fat. Ludwig says this cycle continues until you feed your body regularly (he suggests at least three meals and two snacks in between) with real food made from real ingredients. That matters more than the calories it's made up of, so repeat after us: I will always choose an all-natural version of something over food that's labeled low-calorie or fat-free.
“Belly fat or abdominal fat is the subcutaneous (which means under the skin) fat that sits around the waist and provides a store of energy, and also protection and heat, for the organs,” says Tarik Belalij, personal trainer and nutritionist at Everyone Active Becontree Leisure Centre. “Small amounts of fat below the skin is normal and healthy, it is the visceral fat, which surrounds the organs that can be the most dangerous type of fat – leading to heart attacks and diabetes.”
