In a nutshell:you fast for 18—20 h, “hit” a 15 min HIIT workout exactly at sunset, drink 1 l of electrolyte water → trigger a surge of growth hormones, catecholamines and cell cleansing processes (autophagy) net superior to any strategy used separately.
1 ️ ⃣ Why autophagy?
- “General service” at the cellular level: eliminates defective mitochondria, protein aggregates and internal pathogens.
- Directly linked to a lower risk of metabolic disease, chronic inflammation and cognitive decline.
- It lights up when AMPK ↑and mTOR ↓— translated: few calories and low insulin.
2 ️ ⃣ Fasting takes place... HIIT presses the throttle
Brief Explanation:you enter training already “on internal diesel” (fats + ketones); the HIIT micro-shock forces the cells to quickly recycle spent components → intensive repair mode.
3 ️ ⃣ Role of electrolytes
Fasting + sweating from HIIT = loss of Na¹, K₂, Mg²³, so:
- prevent headache, fatigue, crutches;
- preserve plasma volume → more efficient transport of residual glucose and fatty acids;
- magnesium supports the recycling of ATP → ADP, so autophagy runs without “lag”.
Quick Shot:1 l water + 2 g pink salt + 200 mg K + 200 mg Mg (citrate) → sorbed throughout fasting.

4 ️ ⃣ Practical protocol in 5 steps
- 8:00 p.m.— the last calorie (the previous evening).
- 06:00— water + electrolytes; black coffee optional (obviously no sugar or milk or coconut oil).
- 4:00 p.m.— HIIT (10 min warm-up, then 20 s sprints/40 s break).
- 16:20 — 16:30.— cold shower + 500 ml water with salt 🧂.
- 18:00— protein-rich meal (35%) + fibrous vegetables; reintroduce carbo only if you want to “refeed” (≤ 150 g).
5 ️ ⃣ Common mistakes
- “I skip the electrolyte, I just drink water”→ insomnia/dizziness.
- Too much HIIT (> 20 min)→ chronic cortisol, inhibits autophagy.
- Carbo immediately post-workout→ pick up insulin too early; leave 60-90 min.
With 1.6 g of protein/kg at “feeding” and a single short HIIT, muscle catabolism is minimal; increased GH even helps with conservation.
Walking is ok, but it doesn't trigger the same flow of catecholamines; you want that short, intense metabolic shock.
You can... if you like to have your insulin come to the fixed party when all the guests are asleep. Cheaper and more honest: let the inner chef cook from the protein in the refrigerator! 😄
