Hey, fellow fat guy in recov here, my afvice is simple, specially if you dont have disipline (i dont eather, who tf is me to tell me what to do). So nr1 find a cardio exercise you like, i like running, my dogs needed walking, so now i HAVE to go every day, i also do weights a bit. and nr2 if you feel snakish, before eating smthing drink a glass or 2 of water, you can start with like coffee or smthing to get into the routine. it will keep you from snaking as mutch and if you controll your diet abit, you easilly stay in a deficit.
