I found that the vending machines spread throughout my campus are a HUGE temptation! Yeah, so I have an apple in my bag, but that bag of chips/candy bar/cookies (whatever is the poison of the day) would taste sooo much better. So instead of "swearing off" junk food I buy a full size package of whatever (it is less expensive than the individual sizes) and I use zipper bags to set aside 7 servings (one for each day)and put up the large bag high where I can't reach it and it is inconveinient to get to (as well as out of sight, if I don't see it I don't think about it as much) I also don't keep change or small bills in my pocket, I rarely carry my cash on me. I also schedule a PE class (it is more expensive than using the free facility on campus, but I'm more committed because it affects my GPA if I don't show up and fail)I found the early morning ones are easier for me to schedule around, plus they keep me from staying up all night studying because I have to get up to go to class. If you can, take your lunch, if not try to select healthy..not always necessarily food, if using sparkpeople has taught me anything, it's that I can have the hamburger, but I should probably cut it in half, and instead of eating fries with it I should get a salad. Food type does matter, but serving size does also, if you want "junk/unhealthy" food, limit how much you eat. I was shocked when I found out that a grande latte at Starbucks was like 400 calories, so I get a non-fat tall late..I still get my treat/craving satisfier, but I choose a better portion of it.
With the burn I break up the stress, with my sweat it leaves my body.
