I've been having a bit of a motivation problem. I have now been trying to have a healthier life-style for a couple of months. But recently I plateaued, and have been having difficulty finding motivation since. I know that the best thing is to just keep up with the diet and exercise, but its more difficult to say no (to for example chocolate, or crisps), when you feel like its not having much of an effect. Any ideas on how to tackle this issue?
