I just started insanity today so I dont know how well its going to work for me, my biggest issue is I cant find anyone in my situation. Im 5'10 120lbs so losing weight or inches off my waist would be pretty much deadly for me!! im already underweight and eat a ton. Im confused with how I should diet with this program and how to input it on this site correctly!! Im guessing I need to increase my protein and carbs with shakes etc?
