It's a diet where you limit the amount of sugar, starches, and refined carbohydrates you eat. No candy, potatoes, or white bread products. It's hard at first, but once you get started, it's really easy! After a while, I didn't even want suger things anymore. The other day, I had a piece of chocolate cake and i was like, "Ew this is so gross!" it tasted too sweet! I couldnt even take another bite!
