Fasting Triggers Massive Hormonal Shifts
- A 24-hour fast can raise human growth hormone in men by up to 2,000%, boosting muscle preservation and fat burning.
- Fasting also resets insulin, enabling the body to access visceral fat more easily.
Fasting Produces Predictable Timelines
- After 7–14 days of consistent fasting you get reduced hunger, lower inflammation, improved gut function, better sleep, and mental clarity.
- After 30 days you typically see marked visceral fat loss, higher testosterone and HGH, and easier strength training recovery.
Use An 18:6 Daily Window
- Do an 18:6 daily intermittent fast (fast 18 hours, eat in a 6-hour window like 12pm–6pm) and consume two to three meals in that window.
- During the fast drink water, unflavored electrolytes, unsweetened tea, or black coffee only.
