I lost 26kg and kept it off for about 2 years. Some of it has crept back on as my situation changed. But my biggest advice is to find an exercise that you really like. Exercise is the key to looking and feeling great and will keep you up on top when you have a naughty eating day. Think outside the exercise box and try some things that you may like e.g. belly dancing, boxing, soccer, rock climbing, surfing. So many options Hope this helps.
