For one, act now about it, and trust me you'll be so glad you did. There's a lot of great advice here which is better than I could muster...so... Here's my tip. For weight loss specific you don't have to do intense exercise (save that for when you're in shape). What you should do is light exercise for a prolongued time: so when jogging, go slower but for a longer time. ** Stick to jogging/running. Every day go slowly but for an hour or so (you shouldn't get tired because you're going slow). Keep this up for about four weeks and the fat will come off so fast your friends won't believe it. Instead of eating sweets, why not cut them completely and get addicted to grapes or some other fruit? There might be better advice (I'm not a coach) but it's worked for me before. Go for it and best of luck.
