Ok I've calmed down...
I know that I have a huge family history of how good the "survival or starvation mode" can be. My grandmother was a meticulous woman, she was told to cut her calories to lose weight and she did, and the did again until she was eating 600 cals a day and staying 350+ lbs...At 60 years old she "gave up", let go of ever being thin again and went to 1200 cals a day...her weight plummeted to 140 lbs in 2 years.
I don't know how to continue to lose at this point but I do know that if there is a famine, I will survive it!!!
