yup..good luck......but think about what you said first....doing excessive cardio = use f muscle for fuel.....dieting doesnt require much fuel, just self-control and motivation....the chances of losing muscle on a very on point, macro inclined, diet are less than cardio. I tend to err on the side of diet, as my cardio, although 7days a week, is more for sanity than intensity....5-7 days, I can hold a conversation while doing it......1 day I could sing.......and 1 day I do nothing but sweat, perfusely.
