I know I'm not genetically inclined to obesity due to fact that my parents & my grandparents, my aunts, uncles and cousins are all slim. And so was I for the 90% of my life when I wasn't on medication that made me ravenously hungry leading to the consumption of 1000s of calories

It's counterintuitive, but obesity is about 40-70% genetic. Apparently. https://en.wikipedia.org/wiki/Genetics_of_obesity …
-
You still need to actually eat too much tho.
-
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.

i mean this is obvious, idk why folks are so confused. i mean, no matter how predisposed you are to, say, alcoholism, you'll never become an alcoholic if there is *no alcohol* for you to consume.

The laws of physics are apparently just a myth that can easily be proven wrong by some fat people! They can magically create and store energy in fat without intaking the energy in the first place!

Epigenetics possibly?

Tangentially an Australian (I think) study recently showed that couples make better lifestyle choices (eat better quality food, eat out less, eat less junk, exercise more, smoke less) but tend to be fatter....... I find that fascinating.

That's not true really. There are examples in Good Calories, Bad Calories of poor people who do hard physical labor and still have a relatively high frequency of obesity. Problem for them is that their main food source is carbs.

Genes are only one factor in the equation. The amount you eat is another. But WHAT you eat seems to be, by far, the most important one

I think the tendency to conserve energy has a genetic basis. Some people are habitual fidgeters, pace up and down, tap their feet etc and others remain motionless unless required to move.

There is a strong link between obesity and Lithium deficiency in populations who predominately consume meat products. https://getfit.jillianmichaels.com/foods-high-lithium-1831.html …

Also, that the genes have only appeared in the last 40 years when food has become ridiculously plentiful in developed countries. Check old photos of people from the 40s, 50s and 60s and it is virtually impossible to find an overweight person.pic.twitter.com/DrnJ9nVe0G

That's mainly because of WHAT they were eating, and less because of how much. Check out pre-WWII European food science, and a guy called William Banting.

Of course
