National Nutrition Month Fact vs. Fiction:
o Myth – Eating carbohydrates causes weight gain.
o Fact – Calories caught weight gain. Excess carbohydrates are no more fattening than calories from any source. Despite the claims of low-carb diet books, a high-carbohydrate diet does not promote fat storage by enhancing insulin resistance.
o The takeaway – Strive to eat a diet including carbohydrates, fats, and proteins because all macronutrients play key roles in the optimal function of the human body. It simply isn’t healthy to eliminate one of these three fuel sources!
I know that this is a straw man argument. It papers all "low carb" by attempting to shoot down "no carb".

I need a polite and convincing response to this. Help?
