An abundance of food that we didn’t coevolve with and thus isn’t optimal nutrition.

Modern industrial foods have just shown up in the 3ish million years of homosapiens existence, hell, agriculture is still really new at 13,000 years.

Humans eating the coevolved foods won’t have this type of reaction, i.e. animals meats and fats won’t make even the most dedicated couch potato look like this guy.

Now… eventually, in a few hundred thousand or millions of years eating current processed foods, the future humans will have adapted and be ok with it, but not today

TIL an abundance of food produces potatoes.

To be fair, they have to swim. We just have to get up, open the door, pick up the food, sit back down and eat. Closing the door is optional, because ain’t anyone moving from their chairs.
