Whatever the cause is, I’d bet it’s probably modulated by genetics as well. The Peery paper goes into it too. I have most of those factors other than maybe the virus and I pretty effortlessly maintain a 22 BMI unless I’m drinking 5+ beers a day for months. Obviously anecdote but I know I couldn’t get down to 18 BMI without a ton of effort, just as an obese person can’t get down to 23 without a ton of effort too. Or perhaps the damage is done as a child or in the womb, hard to say.
