The more I eat, the more I lose?

[Globetrotter 1,340]

My daily carb average is between 10-15 grams of carbs per day. My Protein averages 80-90 grams per day and my fat between 20-25 grams per day. This is on 600 cals. In the 5 days of being back on 600-615 cals, I have lost only 1/3 of a pound and I'm pretty sure that was just due to daily Miralax use. I'm nowhere near my cycle, not eating processed carbs or sweets, and exercising. Maybe I'm not exercising enough?

Well I've been super bummed out this week and it's because of calories. I've mentioned it in a few places here on the forum but I was a super slow loser, about a pound a week, when I was on 600 cals. Then I rebelled and started taking in 750-800 cals, suddenly I was losing a pound a day and it was amazing. During this time I finally got ahold of my nut and told her what had happened and what I was doing and her response was to ignore the "proof" and tell me to go back to 600. Being a Good Girl, I did. Guess what? I "gained" almost 2 pounds and haven't lost an ounce since I went back to 600 5 days ago. PLEASE, if anybody has any suggestions/insight/words of wisdom, I am all ears.

What more proof do you need?!!!
