Right Diet = Less Maintenance

Well, I've not been working out properly at the gym for 3 mth now. But I do maintain my diet properly... as much as I can.. hahaha... since staying with family is not helping much when they don't see my diet as eating at all.. lol. anyways, i tried my best and keep my heartbeat on check everyday by having at least 1/2 hr cardio daily. with resistant exercise accompanied.

So how do i look after not gyming 3mths?
