When I started at 370lbs I was eating about 2200-2300 calories and have slowly been decreasing it. Right now I'm at 1600-1800 calories a day depending on how much exercise I do. Starting out there's no way I would have been able to eat any less than 2000cals a day. I would have lost my mind. Since I'm doing things slow and steady I've been able to get used to lowering my calories and staying within them.
