Fasting: A Starting Point

What it is, what it can change, and the part almost nobody talks about.

Simple in concept. Not always simple to apply well.

Fasting sounds simple — don't eat for a period of time. Applying it well is where it gets more interesting.

This free four-page guide is the short, evidence-based version. No detox claims, no protocol to follow, and no pretending the research says more than it does.

• What fasting actually is — and what it isn't
• What it can genuinely change, and where the evidence stops
• Why the eating window matters more the shorter it gets
• Hormonal stage, the menstrual cycle, and why there's no single calendar
• Who shouldn't fast, and the signs it isn't working for you
