Why does gastric bypass work?

[Anonymous]

I keep hearing that the amount of food a person eats doesn't affect their weight and that it's genetic or health conditions. If that's the case how could gastric bypass even work? I even hear that eating less causes weight gain. So wouldn't people get really big after the procedure?

😂 that girl is trolling you bro. Stop it. There is no medical literature that shows that starvation causes weight gain. All of the Holocaust starvations and not a single fat person. All of the PoWs from many wars, and no one ended up obese. Don't be naive.

Not everyone is speaking in bad faith. Some people just received bad information. Especially when it has to do with health.

Sure but some people are just outright lying for their agenda. Calorie deficit is what causes weight loss. All the surgery does is force most people into a calories deficit. Some dedication food addicts can eat past it, but that's not the norm. The surgery just makes it so people can't overeat anymore without puking.

Excessive calories is how you gain weight. If you take in more calories than you burn your body stores it as fat. 100 calories of chocolate is the same as 100 calories of vegetables. The difference is the nutritional content. If you increase the volume of food you are increasing the amount of calories because you are consuming more. You are a fucking idiot for not knowing that.

[Asker]

You're a fucking idiot for not comprehending the question. You might actually have a learning disorder.

The surgery creates a small pouch at the top of the stomach, limiting the amount of food it can hold.

[Asker]

And does this mean that people eat less calories after the surgery? Could they also eat as if they got the surgery, without actually doing it?

[WhitneySnow]

That’s not true. The amount of food you eat is definitely one factor (but not the only one).

[Asker]

So eating less calories than you need will make your weight go down? Not make you gain weight from starvation mode?

[WhitneySnow]

At first it will. But then if you keep it up without exercising your body will go into starvation mode and you’ll gain weight.

[Asker]

So how does the gastric bypass work? Those people stay in restricted diets for years. Shouldn't they start gaining weight? Besides the ones that eat through it and stretch their stomachs back out. Not talking about those ones. It just doesn't add up to me.

[WhitneySnow]

I’m not sure. I guess somehow it disabled the starvation mode. Are you really obese? If not you shouldn’t even be thinking about gastric bypass surgery.

[Asker]

For my sister, not for me. I'm probably not even overweight. She's planning on getting it and I told her to just eat like she got it and she says it doesn't work that way. Which literally makes zero sense to me. I wish she would at least try it before the surgery. Her doc made her do a diet before approving it and she lied and didn't follow the diet. Actually she started to follow it, started losing weight, then went back to not following it. So by the next checkup she gained the weight back. I feel like I'm crazy right now tbh. Like I'm being told that I'm not seeing the thing that I'm looking at.

[WhitneySnow]

She’s right. It doesn’t work that way. But she really should follow her diet. The surgery is very painful, so bad that I heard about a girl who got it who got addicted to painkillers because of it.

[Asker]

That's why I'm trying to understand how it works. If it makes you eat less, and eating less makes you lose weight, and eating less during the trial before surgery makes you lose weight, then why doesn't eating less without the discussion of the surgery, or the actual performance of the surgery, also make you lose weight?

[WhitneySnow]

Because eventually if you don’t exercise too your body will go into starvation mode and you’ll stop losing weight and start gaining again.

[Asker]

But that won't happen if you get the surgery? Like, the starvation mode is shut off by doing the surgery?

[WhitneySnow]

I think so. Not sure.

[WhitneySnow]

It does work but it’s very painful and very risky

[In_Trance]

It doesn't work

[Asker]

Then why does everyone lose weight from it?

[In_Trance]

Then they gain it all back

[Asker]

Because some eventually stretch their stomach's back out. Which means they are able to eat more calories again. Which means that the amount of calories they eat dictates their weight. Right?
