It seems we've been obsessed with cutting carbs in order to lose weight Of course protein and fiber matter for losing weight, but healthy carbs can do just the same. In reality, most of the vitamins and nutrients we need to burn fat as well as fiber to keep our stomachs flat are found in carbs. People are typically cutting carbs to lose weight, but typically this is water weight you are losing. So you might be battling the bloat, but you won't see any real results but just cutting carbs. The goal is not to lose water weight but to lose fat. The way to do this is more exercise, clean eating and smaller meals.
