Hunger isn’t linear — it’s rhythmic. Research by Frecka and Mattes found ghrelin spikes occur at habitual meal times regardless of whether you’ve eaten — the hunger is real but clock-driven. When you skip a meal, ghrelin rises, peaks, then falls again. The body doesn’t escalate indefinitely. Additionally, as the body switches from glucose-burning to fat-burning, initial hunger often diminishes. Wait out a hunger spike during fasting and it passes in 20-30 minutes.
This companion covers conditioned hunger, the metabolic transition, the 20-minute rule, and using the wave. (4 min read)
Known defects on this page:
- em dashes were set without spaces The site's style spaces its dashes; 351 pages carried them un-spaced, and every one was corrected.
- We overuse the em dash in our prose. We use the em dash more often than easy reading allows, and we are changing how we punctuate.
