Losing weight is really just a simple math equation and comes down
to calories in vs calories out. In order
to lose
weight, you have
to burn more than you consume. People lose weight on low carb diets because whether or not they realize it, they're consuming less calories. High carb foods (cereal, potatoes, rice, pasta, sugary snacks) tend to be quite calorie dense so a very modest portion can end up being pretty caloric.
