why hunger comes in waves (and how to ride them without breaking your fast)
one of the biggest myths about fasting is that hunger just keeps growing and growing until you eat. it’s actually the opposite. hunger isn't a mountain you have to climb; it’s a wave that peaks and then fades away.
this happens because of ghrelin (the hunger hormone). it doesn't stay high; it pulses based on your usual eating times. if you can wait out that 20–30 minute wave, it usually disappears.
i was reading a deep dive into the science of these hunger spikes recently, and it explains exactly why our bodies react this way and how to "train" your hormones to stay calm during a fast. it’s a world-class breakdown if you want to understand the "why" behind the struggle:
