I think that some people think simply changing out the high carb for the low carb will do it. And I do wonder....would these people lose weight? I mean their diet WOULD be lower in carbs. It's like switching to Diet Coke. For an avid Coke drinker, completely switching to the diet kind would maybe result in a good amount of weight loss over a year even if they don't make any other changes. They'd be shaving off anywhere from 300 to 1000 calories a day, depending on how much they drink. And what if that person also cut out white bread, other excess sugars, and potatoes (which is where many people start to cut carbs). Would they lose even more? Would they lose any?
