I just started dieting one month ago. I weighed myself two months ago. Two months ago, I weighed 183lbs. When I weighed myself one month ago, I weighed 183lbs. Now, over the month that I've been dieting, I've lost 9lbs. That sounds confusing, but point being, I didn't gain anything in the one month that I was living and eating "normally."
Well "normal" for me was awful. I think it would be safe to say that I didn't eat a single vegetable for that whole month unless it was a chunk of broccoli in Chinese food or something. I'd eat an entire box of Kraft Mac and Cheese for dinners 3 or 4 times a week. The days I wasn't eating mac and cheese, I'd eat fast food. I'd eat a whole bag of Fun Size candy bars over two or three days. I'd make a batch of cookies and eat the whole thing in a couple days. I'd eat Lean Cuisines, but I'd eat a panini with a whole pasta dinner on the side. I wasn't so much of a binge eater, I'd just be constantly eating junk and lots of it. Any one of my meals or snacks would be considered a binge of monstrous proportions now. I plugged in an average day of eating for me on a calorie counter, I was eating at least 3,000 calories a day of bad carbs, sugar, fat, some fat-drenched protein, and sodium.
For exercise? Nothing. Walk to class. Walk around Walmart. Move from couch to kitchen to computer chair a few times a day.
So how in the world did I maintain my body weight for a month like that? And I've lived and ate like that for about 3 years. Yes, I was heavier than I ever was, but how was I not gaining 5lbs everyday??



. I think we're just beginning to learn all the reasons different people gain, maintain or lose at different calorie, nutrient, and activity levels, as well as other things that have an influence, like sleep deprivation, stress, and so on.
