The best thing you can do for your body is to NOT eat the white carbs. You can add whole grains, if they aren't a food that you react to. Thinking in terms of "I'll do this until I lose the weight and then go back to eating 'normally'" is not the way to go. That leads to yo-yo dieting which really isn't good for your body. You have to think in terms of lifestyle change. Research all of the plans and then find the one that works best for you FOR LIFE. Even this FF plan has a lifetime eating plan (phase 3). Making a lifestyle change will help you be healthier throughout your life which really is the ultimate goal.
