Oh
raw, you are NOT ALONE! On Halloween, I, too, consumed around 4,000something calories. But yes, you need to go OVER your BMR by 3,500 calories to gain one "real" pound.
I was RAVENOUS throughout most of the morning and afternoon. It was legitimate hunger, and at first, I was on plan. THEN... I started eating nachos (my boss brought a huge platter in and plopped it on my desk - he loves to feed me - it's because he legitimately cares about me and wants to see me happy and to him, food is love, but I'd rather him not!), followed by a pint of ice cream, followed by a BBQ chicken sandwich, some ribs, a big piece of garlic bread, half an order of onion rings, and THEN (I went to two parties) five jello shots, three beers, two whiskey & Dr. Peppers, some gummy worms, some chocolate pudding, a couple Oreo cookies, a few Doritos ANDDDDD to top the night off, we went to STEAK & SHAKE where the girlfriend and I split a double chocolate shake, a large order of cheese fries, and I had a little burger.
The next day, I was definitely NOT feeling very good.

I'm pretty sure my body had no idea how to tolerate all the crap I fed it. I'm feeling fine today and after Halloween, I was back on track as usual. And yes, to answer your question, I did eat much less yesterday than I did on Halloween.
You don't need to beat yourself up over one binge day... if you've been otherwise on plan with your diet and exercise regime, it isn't the end of the world if you mess up every now and then. We're all human, right? Maybe your body was just extra hungry due to your "every other day" dieting and felt like it "needed" more calories? I have found that often, when we binge, there IS a legitimate reason within our bodies why we do it; we just blow that out of proportion and go overboard.
