the secret for me was just cutting out all the shit i was eating, i’m 5’10” too and used to weigh 14st, too much drinking, take-aways and snacking on crap through the day at work, it all pretty much dropped off when i decided to stop eating all that, I also started getting back into biking just at the weekends at that time. I now hover around 12 stone, cycle to work fairly regularly and try not to eat too much crap, I think the cycling allows you to eat some crap without gaining weight but if your trying to loose weight you should stay away from the junk. That probably all sounds a bit obvious.
