Recovery and sleep: half the method happens at night

After one night of four hours, ghrelin — the hunger hormone — rises by a quarter, leptin — the satiety hormone — falls by a fifth, and the next day you eat 300-500 kcal more, choosing sweet and fatty foods: the brain is looking for quick energy. A week of five-hour nights reduces insulin sensitivity by 25% — in healthy young people, to a prediabetic state. Evening cortisol does not fall, water is retained, strength training produces no gains because growth hormone is released during deep sleep, which was missing. The result: the same plate, the same method — and the weight stalls. Section — sleep: what happens at night: hunger hormones and sleep, sleep stages and fat.

Cortisol is not the enemy. In the morning, it should be high — it is what gets you out of bed — and by evening it should fall to a minimum. The problem is when it is always high: working without breaks, sleep deprivation, anxiety, overly long fasting, and hard training on top of it. Then blood sugar stays high without food, fat accumulates around the belly, muscles break down, sleep becomes fragmented, and any diet works at half strength. The key is the daily rhythm, not “lowering cortisol.” Section — stress and the nervous system: the daily rhythm of cortisol, heart rate variability, breathing and the vagus nerve, overtraining and burnout. About cortisol in women — stress, cortisol, and weight.

The body lives by its internal clock, and insulin sensitivity is 30-40% lower in the evening than in the morning: the same food at 21:00 causes a greater rise in blood sugar than at 9:00. A late dinner shifts the clock, worsens sleep and its depth, and makes you hungrier the next morning. Hence the method’s rule: dinner before 19, light in the morning, darkness in the evening, and the fasting window — not only about calories, but about synchronizing the clock. Circadian rhythms and meal timing, falling-asleep protocol. About nighttime hunger — nighttime hunger and sleep.

A deload week every 4-6 weeks — progress afterward is greater than without one. Active recovery — walking, light mobility — speeds recovery better than complete rest. Sauna: among Finns who went to the sauna 4-7 times a week, the risk of cardiac death was twice as low as among those who went once a week, in a study of 2300 people over 20 years. Cold: cold water increases noradrenaline 2-3 times and improves mood, but immediately after strength training it interferes with muscle growth. Sleep supplements: there is evidence for magnesium and glycine; low-dose melatonin helps you fall asleep, not stay asleep; “sleep complexes” — no evidence. Section — recovery tools: deload week, active recovery, sauna and cold, sleep supplements.

Snoring with breathing pauses — sleep apnea; it can be treated and explains “I sleep 8 hours and feel wrecked.” Insomnia lasting more than a month despite following the right protocol. Waking with a racing heart and sweating — thyroid issues or perimenopause. Fatigue that does not go away after two weeks of normal sleep — ferritin, B12, TSH, vitamin D. Sleep is not only about habits; sometimes it is a lab test.

Sleep: what happens at night — hormones, phases, rhythms, and a falling-asleep protocol. Stress and the nervous system — cortisol, heart rate, breathing, burnout. Recovery tools — deloading, sauna, cold, supplements. The foundation — method, training; sleep on a low-carb diet — sleep on LCHF, stress and weight — stress and sleep deprivation.
