Gardening on GLP-1 — my results so far

Neuroscience perspective on food noise:

GLP-1 receptors are expressed throughout the CNS, with high density in the hypothalamic arcuate nucleus, area postrema, and — critically — the mesolimbic reward pathway[1].

This is directly relevant to food noise because the central effects of GLP-1 agonists extend far beyond simple appetite suppression. The reduction in "food noise" that patients describe is likely mediated by modulation of dopaminergic signaling in the VTA and nucleus accumbens.

The emerging data on reduced addictive behaviors (alcohol, gambling) further supports this mechanism. food noise should be understood in this broader neurobiological context.

"Food aversion" side effect of food noise that I wasn't prepared for: I used to LOVE cooking and trying new restaurants. Now certain foods — especially red meat — literally repulse me.

It's not just reduced appetite; it's an active disgust response. My therapist says this is common and likely related to the reward pathway modulation. It's mostly a positive change, but I do miss enjoying food the way I used to.

Phantom hunger vs real hunger on food noise: learning to distinguish between the two has been a revelation. Real hunger: gradual onset, physical stomach sensation, any food sounds good. Phantom hunger: sudden, emotionally triggered, specific food cravings, occurs right after eating.

The GLP-1 agonist suppresses real hunger beautifully. Phantom hunger still pops up but I can now recognize it for what it is — an emotional signal, not a physical need. Mindfulness training helped enormously with this distinction.

This is my experience too, for whatever a second data point is worth. I had assumed I was the exception until I read this.
