Depends on your age really. you may find if you go back to eating what you did before minus the junk that you just stay the weight you are. better to find a diet that works for you either as a club like SW or WW or something online and try and shift it a pound or two a week. it took a year to go on so might take 6 months to get off and stay off. also being overweight is about the habit of it so whilst you can see that you are eating junk there might be some hidden calories in there to. i would say look at your exercise and then look at joining a club to get the stone off.
