71, It is entirely normal and OK. I am so glad and relieved for you. Your body has been starved for a long time and doesn't trust you.
What I would recommend is to try to eat mindfully. In other words try to slow down and appreciate what you are eating. Don't beat yourself up if it is frantic as your body and mind have to learn to trust that you won't starve them again. Keep reminding yourself you won't and try to avoid beating yourself up when you can.
Also try to think of how you feel emotionally before and after you eat. After you have given yourself some time what you want to do is check in on yourself and see why you are eating and how full or empty you are at regular intervals. Eat regularly too.
If you separate your emotional and physical life and respect your bodies hunger signals you will not fall into either spectrum of the ED behaviours. It isn't easy but with work you can do it.
These are all ED behaviours: restricting, fasting, laxatives, purging, avoiding certain foods for illogical reasons, being obsessed about the healthiness of food in a way that interferes with health, compulsive overeating (when we are not deprived nutritionally and yet eat frantically and when we are not hungry), objective binging (about 2000 calories plus in a short space of time and frantically), over exercising etc...
Your body and mind are probably hungry at present. Keep in touch with them and treat them as respectfully as possible. Have you ever read the Minnesota Starvation Experiment? They all ate in an out of control way initially and then normalised.
