And yet it's a strange coincidence that obesity genes are so common in countries with lots of junk food, less common in ones where there isn't and not common at all where food is scarce. https://twitter.com/Hereditarian98/status/974249011048734720 …

Is it really that these genes are so prevalent in America and have suddenly increased in the last 50 years? How would that happen? Did fat people suddenly become really attractive so they got all the mates? It doesn't make sense not to focus on lifestyle

I dunno. I need to read up on it. It could be effects on metabolism, or it could be that people with 'obesity genes' are more predisposed to gorge when there's a food surplus. I honestly don't know.

So it could be a gene-environment interaction. I dunno. I'm no expert on these things.

Probably, yes. Also a psychological comfort thing for many people. Doctors keep thinking this could be it for me but it isn't. I don't really think about food much. I just cram whatever is easiest in when hungry - usually toast.

Yes, but perhaps those genetically predisposed to obesity are simply hungrier? Your appetite was increased on meds. Maybe that's what it's like for those inclined towards obesity. They're hungrier and it takes more food for them to be sated.

Well, obviously. But too much will vary from person to person. Also type of calories matters (hence keto). Also lifestyle. Also hormones (teen boys eat and lose fat/gain muscle etc.). Also age. Calories in / Calories out is so horribly over-simplistic.
