I struggle with this advice b/c I have a severely sluggish thyroid and I do not metabolize the way other people do, even when I am extremely active. I am a runner, I cycle, and I play tennis. After two injuries, even watching my diet, I gained 15 lbs. because I was unable to exercise. If I followed this formula, I would be incredibly overweight. What do you suggest we "tweak" in the formula if we have hypothyroidism?
