Keto + intermittent fasting
3 min read
Intermittent fasting (IF) and keto are natural partners. Fat adaptation makes fasting effortless, and fasting deepens the fat-burning effects of keto. Once adapted, most people fast without thinking about it.
Why the combo works
On carbs, you eat every 3-4 hours because insulin spikes cause glucose crashes. On keto, stable ketones keep hunger and energy steady for 8-12 hours at a stretch. Skipping breakfast is no longer willpower — it is just comfortable.
How to start
After you are fat-adapted (week 3-4), try 14:10 — stop eating at 8 pm, eat again at 10 am. Once comfortable, extend to 16:8 (noon-8 pm window). Only progress further if it feels easy. Forced fasting backfires.
What it does for you
IF lowers insulin further, raises growth hormone, and triggers autophagy (cellular cleanup). Practically, it simplifies your day, saves money, and accelerates fat loss during plateaus. Most people see their biggest breakthroughs after adding IF.
- Fat adaptation makes fasting feel natural
- Start with 14:10, progress to 16:8
- Never force it — discomfort means not ready
- Biggest plateau breaker for week 4+
