When you first start, you lose your glycogen stores in your muscles and liver, which are bound up with water. That's why you get a fabulous loss your first week or two. After that, when you're relatively light, losses are slower. When you're only losing a pound or two a week, a salty meal or monthly water retention can make it look like you're not losing a thing. Don't get discouraged! Keep at it. You can't be gaining weight on 1000 cal per day. If you're on program, the losses will show up on the scale eventually. I bet you'll have a big week this week if you stay on program.
It evens out over time!
