Hiking trails for newly active people — recommendations by difficulty

Neuroscience perspective on food noise: GLP-1 receptors are expressed throughout the CNS, with high density in the hypothalamic arcuate nucleus, area…

"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 sweets — 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.

The food noise came back three weeks after I reduced my dose, well before the weight moved, which tells me something about which effect tracks what.

Alcohol relationship change with food noise: I used to drink 2 glasses of wine most nights. Since starting GLP-1 therapy, I have zero interest in alcohol. Haven't had a drink in 6 months.

The "food noise" reduction seems to extend to other reward-seeking behaviors, including alcohol. My liver enzymes have improved, my sleep is better, and I've saved roughly $204/month on alcohol. Triple win.

...regarding food noise mechanism of action...

To build on this — the mechanism is more complex than "it makes you less hungry." GLP-1 agonists:

1. Activate hypothalamic satiety centers (appetite reduction)
2. Delay gastric emptying (prolonged fullness)
3. Potentiate glucose-dependent insulin secretion
4. Suppress glucagon secretion
5. Modulate reward pathway dopaminergic signaling
6. Reduce hepatic lipogenesis
7. Have direct cardiovascular protective effects

It's a multi-target drug with systemic metabolic effects. Understanding the mechanism helps us predict and manage side effects.

One thing that is still open after lisa_labSD’s answer:

Did your prescriber agree with that reading, and if not what was their objection?

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.
