Mmkay here are the details...I have a little bit of a gut and I am finally doing something about it, I go for walks everyday just after I wake up before breakfast, I am on a eating plan to avoid carbs at night to avoid fat gain.And in the afternoon almost everyday I head over to a mate's place to do weights.So how long would it take for me to notice any difference in my size? Not weight, but visablly?
