I really like the cooking light magazine. If you drink coke products, or if anyone you know drinks coke products, you can get a year subscription for a low amount of points. I love the recipes in it, and it actually tastes good! First, make some healthy, lower calorie snacks, and eat constantly. Eating small meals keeps your body working, and as long as it isn't loaded with high calorie items, it'll be less calories in the long run. If you have a wii, the wii-fit really works. If not, set aside some time in the morning- 15 minutes or so, and just do quick exercises. In marching band we would do the alphabet with our feet and not touch the ground- you start feeling it after 'L'. We'd also do jazzercise- grapevines and punches and arm circles.
Most of all, don't stress over it. don't force yourself to do something you don't like- replace it with something you do like.
