I'm no expert or claim my way works for everyone or that it is healthy, but, before dropping all the bad shit out your diet just try the exercise, I did just that, not on purpose but by change of circumstances. few years ago when I was a bit skint the car broke and couldnt afford to fix it, so I started using the bike to work and back and everywhere I needed to go basically, and in about 6 month's lost roughly 3.5 stone, went from 16.5 stone to near as damn it 13 stone, plus by the end I couldnt tell I'd been on the bike when I got off it, no loss of breath or knackered etc.

So just by exercising I lost the weight, I wasnt in a position to change my diet either cause I was living at home so I didnt do any of the food shopping or cooked any of the meals, was eating exactly the same meals and same amount, it just got burnt off before it got chance to stick

Now weigh 14 stone and I dont exercise out of work, but I handball 10000kg of steel 5 days a week and apart from the odd fucked joint/muscle I dont feel to bad, although stamina is now shocking, must try and get back on the bike, sorry for waffling on
