Summer appetite loss

I just learned something interesting. I have never noticed this before but this year, my appetite has plummeted during the summer. I kinda feel full about food.

Looks like the hotter it is, the less you need to eat because your BMR has gone down (no need to cool the body). Huberman’s shivering?
