About this episode
A low dose of tirzepatide, taken purely to move the needle on cholesterol, turned out to move a lot more than that. In this episode, Jeff sits down again with Dr. Robin Berzin, founder of Parsley Health, to go through his bloodwork and an unexpected side effect: a blunting of desire that shows up in his coffee, his cocktails, and his ambition.
- Why losing your appetite for food can also mean losing it for coffee, alcohol, and sex
- What the dopamine and serotonin circuitry are actually doing on a GLP-1
- The line between healthy desire and maladaptive craving, and where these drugs land on it
- Why some people feel liberated when "food noise" disappears, and others feel flattened
- What Jeff's ApoB and LDL numbers say about who these drugs actually help
This episode is for anyone on a GLP-1 or weighing one, and anyone curious what these drugs are doing beyond the scale.
