Calories

You should do what your body tells you to do. But there are a lot of people on here who are actually losing more while eating more (there is a thread called something like 'People who lost MORE while eating MORE', search for it, it's very interesting).
How much less than 1650 are you eating?

How many calories have you been eating? When I joined I was eating 900 per day and I was convinced that was the right way to go. After all, eat less to lose more right? Well, I followed the advice of others on the site despite my fear of gaining weight and upped my calories to 1200. I gained 2 lbs over 2 weeks and then started losing, and I felt so much better. A couple of months later I upped my calories to 1470 and stayed the same for around 3 months. No changes good or bad. Last week I went back down to 1300 and started losing again. So it's part learning the rules (you have to eat enough to fuel your metabolism so it doesn't slow down, but you can't eat so much that you're no longer in a calorie deficit) and it's part experimentation. When you do experiment though make sure you give yourself time to adjust. If I'd seen 2 lbs of gain and decided that wasn't working then I'd still be at 900 calories per day and miserable.

I'm with Kim Bensen and she says I need 1450. 1620 is a big difference. Thanks for all the advice. I've heard about the need to eat more...it sounds crazy. Last week I did between 1200 and 1300 and lost 6.7 pounds! I'll see what happens this week. Meanwhile, how do I get the program to put it down to 1450? I've browsed around but don't see how to change it.

I think eating 1450 is good. As long as you eat some of your exercise calories back.
I haven't set it up manually but pretty sure you can go to 'goals' (in 'my home') and then change your goals and there is an option that you can set it manually.
