I think letting go would mean that you didn't count that you ate 21 raisins. Right?
My thoughts on lingering ED once the emotional issues have passed is your body still fighting undernourishment. Have you considered doing something along the lines of what Zach has recommended to me in terms of diet? I know I'm doing it for physical health mainly (as opposed to mental health) but I've said enough times that it has all but eliminated my anxiety with food. And I'm not eating a "ton" - 1800-2000 kcal/day.
Also, not to rock the boat, but I gained more than 2-3 pounds (of fat) on "eat a ton" an was eating significantly less than YB. However, a) didn't you experience a weight gain (more than the 2 lb) in the middle of the experience? And b) I know some people think macros are a load of malarkey but I was eating pretty high fat and I'm with Choco and whoever else that, in a caloric surplus, fat -> fat faster than the other macros -> fat. I am now eating to satiation as opposed to stuffing myself and eating ~250 g carb / day which is a ton for me and losing that weight that I put on. So maybe if I was "eating a ton" with carbs vs fat I wouldn't have gained so much weight but it already served its purpose (to quell anxiety) so I don't feel the need to find out.
Also whatever YB has been saying about everything else... Just listen to her. You don't need me
Is it weird in here, or is it just me?
