Em, do you mean you don't know how you change your goals in FitDay or you don't know what you should change your goals to?
There are no specific breakdowns of how much protein, carbs, or fats you should be getting that I am aware of. I do know some of the chicks use FitDay so maybe they have an idea of what it should look like? The plan is all about NOT counting or measuring so I guess that's why Dr. Agatson doesn't get that specific.
Good luck!
