Most days I manage around 1500 calories, but some days, like once, maybe twice a week, but rarely concurrently, I miss lunch and end up with around 900 calories for the entire day. I always have a healthy breakfast, either an egg white omelet with some low fat cheese, oatmeal with some milk and honey, or fat free yogurt with some kashi GoLean Crunch. I usually have a snack during the afternoon as well, either some craisins, or baby carrots, and a cup of coffee with a little sugar, and then dinner, usually consisting of brown rice and chicken breast with steamed broccoli or something similar. If I get less than 1000 calories for only one day and then go back up to 1500ish, will this put my body into starvation mode, or does it take a couple days to get into it? I'm just trying to lose some extra pounds and I'm pretty much a noob. Thanks.
