Congratulations on your weight loss so far!
I agree with gagalu, you are starving yourself. I burn around 2,000 to 2,500 per day and eat on average from 1,500 to just over 2,000 calories per day. I try to eat every 3 to 4 hours. In the afternoon I might even have two healthy snacks. I make sure I get in a lot of fiber and protein rich foods. I also drink a minimum of 80 oz of water.
I find it very helpful to keep track of all calories going in and being burned. I try to keep my calories burned around 500 to 1,000 above the calories taken in.
Once you up your calorie intake and do that for awhile you should not feel like you need to go on the bingeing episodes any longer.
You can do this!! Remember this is about a healthier lifestyle change. A benefit of this is losing extra pounds. Those extra pounds will take time to come off though.
