Even if no one over-ate there would still be hunger. There is not hunger due to lack of food. It is a deliberate and predictable outcome of our economic system.

This would be immediately spun into

"World food sales down 40%, grocery stores in shambles, Wendy's files for bankruptcy despite having $20B in liquid cash"

i'm just thinking of how much personal information they would need to collect for this to be anywhere near working.

What?

Hmm... Okay?

Where is the joke?

It's the "perfect amount of food" but nobody said anything about the taste.

Also if the diet was optimised (much less red meat, and meat in general), imagine how much carbon emissions would reduced.

This implies that waiters are the root of all evil.

I don’t stop eating when I am full. I stop when I hate myself. I think this was Louis CK

A machine that cannot feel hunger must not be allowed to choose whether to feed a person.

Period.

I get the good sentiment but remember overweight can be not a problem of finishing your meal and wanting another. There are myriads of factors, sometimes (many more than tought IMO) your genes are just coded to be wide that's it you can look overweight and go to the doctor to get all health tests and they return healthy. You can also have conditions that make you overweight like hypotiroidism. Your body shape does not define your health there is science for that. There is loads of thin ppl with cholesterol and heart problems out there...
