weight gain and bingeing

i know there's no upper limit in gaining but i really don't want to keep up these kinds of eating habits when i get to a healthy weight. for example today i ate my usual amount of needed calories for weight gain with breakfast, lunch, dinner, and snacks. although when i went to jason's deli with my mom i still felt somewhat ravenous and ended up eating a big turkey sandwich with veggies, a couple packaged crackers, graham crackers, two small cups of soft serve ice cream and some nuts/dried fruit/trail mix and mini muffins from their complimentary goods bar. okay i definitely felt full afterwards and my heart felt like it was racing. i also felt like i ate my meal in less than 5 minutes. was it just because i was still hungry or because i was bingeing? I don't even know anymore... although i know i shouldn't feel guilty or anything because i'm still at an unhealthy weight i just don't want to keep eating like this when i'm at a healthy weight ugh.

I know exactly what you mean, but it's nothing huge to worry about: the doctors I've seen say bingeing when your trying to gain weight is normal, the natural "I'm full feeling" is taken over because your body is desperately trying to get healthy again (basically you're stomach's satisfied and full, but your body isn't yet). They say that once you're at a healthy weight again this won't happen because it's no longer needed, and it will be much easier to stick to normal eating patterns. But it's still scary! My heart races too and I get really hot. Gaining isn't all the fun I thought it would be

You went to a buffet, right? From what I can tell if you don't go to a buffet often it is pretty normal to splurge a little bit. I wouldn't kick yourself. And like Claire said, it is also quite a normal reaction early on for your body to first go, "Oh holy moly, food!" and start crying out for it because your body has been damaged by being underweight (and possibly restriction or malnutrition). Either way if that was a one off thing then believe it or not - you just engaged in some normal eating. Because normal people go to buffets once in a while and get a lot of food.
