This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Yep, that's leptin resistance for you. Obesity is really a hormonal condition, and this is why GLP-1 inhibitors are so effective - they actually treat the hormonal condition and allow the recipient to manage their food intake without having their body hormonally work against them.

A layman's explanation (to be clear, I am the layman) of my best understanding of the subject:

Hunger is controlled by 2 hormones:

  • Ghrelin, which causes hunger and is produced by the stomach
  • Leptin, which suppresses hunger and is produced by fat cells

As fat cells accumulate, leptin levels also increase, but a person that has developed leptin resistance will not feel the appropriate amount of hunger suppression from the leptin, leading to chronic hunger unless large energy intake is sustained.

Does either of those cause/prevent actual starvation feelings, like headaches and fatigue? Do they influence your non-exercise activity thermogenesis? (ie, feeling like you need to sit while you wait for the bus instead of standing or pacing) Or is it just a vague munchiness?

I don't know the subject well enough to tell, unfortunately.
