Guilt after bingeing

I just pay attention to weekly calories. And because of that, yes, I will "binge" one day/week and have less calories another day. Because I feel like it. And my body neither stores fat nor extra weight because of this.

You're not going to gain weight. You might see a fluctuation but not a real weight gain from one day...

I don't believe in the logic of such extreme calorie save-up's. The body doesn't know this. It just sees a butt load of food coming down the shoot, fires up sugar storing devices (sugar spike) and stores it as fat. It doesn't know that it has eaten nothing all week because this particular day is coming. It just thinks, not much food coming and now we've found some! SAVE IT!!!

That's my overriding belief from everything I've read.

And just my opinion.

^ this ^ I agree with this poster. I never starve my body. I work out too hard to deprive it. I can't wake up in the morning and expect my body to do an hour of cardio and then do weights and not feed it. Our bodies go into starvation mode if we deprive them and hoard what they get, as the poster above explained, we will lose muscle and store fat. One day of eating a little over isn't anything to worry about as long as it is only once a week or less. I maintain just fine eating my daily calories, plus eating back my work out calories. I may eat a little over twice a month, but still maintain just fine.

I don't believe in guilt. I believe in learning from my mistakes.

Some days I overeat, some days are quite light. The week usually evens out. As long as you are eating enough to sustain you and not so much you get unwell, it's all good.

For weight loss you need to be in a consistent caloric deficit. If you go over on calories one day then you can eat fewer on another day, or throughout the rest of the week, and still be at a deficit at the end of the week and lose weight. However, it is unhealthy, and almost eating disorder territory, to 'binge' eat and then 'punish' yourself by heavily restricting yourself afterwards, so be careful not to do this.
The amount you ate probably won't make much difference. You may have put on some weight from replenishing muscle glycogen, and some from water, and perhaps a pound of fat. At most it will set you back a week or two in your weight loss journey, which is nothing.
You shouldn't be so obsessed over/afraid of weight gain that it causes you such issues psychologically, it isn't healthy.

P.s. While starving your body is of course bad, there isn't really such a thing as your body going into 'starvation mode'.

Screw guilt. Your body might be simply screaming for carbs because all that exercise made it raid the carb stash it likes to keep for moments like that. Try shifting some more of your calorie budget to carbs according to what you burned exercising, and see if that solves the cravings as well as that overall drained feeling that tends to go with the territory.

First of all, you really ate that much in the kind of relatively low cal food you're talking about?

Second, I find that when I eat too much at a sitting I feel sick. One of the things I've really learned to do is to know that a small amount of yummy is good, but a lot doesn't make me feel better. It makes me feel like I've overeaten. I don't like that feeling.

Third, 'guilt' implies a moral lapse. Food isn't about morality. Maybe you made a mistake and ate more than you should have, but it's just food. It SOUNDS like you made some good decisions at the buffet. Next week make better decisions - same kind of food, but less of it. Then it will be easier to fit into your weekly calorie goals.

^^^^This!! It makes so much sense it hurts!
