Summary

Host Dave Asprey interviews Sarah Kennedy, founder of Calicurb, to explore the science of hunger and a hops-based supplement that mimics GLP-1 effects. Kennedy explains how the extract stimulates gut bitter taste receptors to release appetite-suppressing hormones like CCK and GLP-1, resulting in significant fat loss without muscle loss. The discussion covers clinical trial data, the product’s role in intermittent fasting and gut health, and its potential as a safer, more sustainable alternative to injectable weight-loss drugs.
