Well it does sound like you recognize the accountability. Unfortunately I really do not have any inspirational stories to share regarding good eating habits.
Good lucky though. I'm sure you will loose it quick. Men typically seem to.
you can do it. just exercise lots (find a buddy to gym with or join a uber physical activity) and eat healthy. word of advice, dont try and cut out junk food completely but rather cut back (like instead of a chocolate bar and a packet of crisps, just eat one).
