Intermittent Fasting for Women Over 40: What Works and What to Watch For

In This Article You Will Learn:

1. How intermittent fasting affects women’s hormones over 40

2. The risks of over-fasting in midlife

3. Why women need a different approach than men

4. What the Keto-Green® strategy brings to the table

5. A safe, energizing fasting schedule you can start today

Intermittent fasting has become one of the most popular health trends in recent years. And for good reason: it can support metabolism, improve energy, and help regulate blood sugar. But when it comes to women over 40, there’s more to the story.

Hormonal changes during perimenopause and menopause mean that fasting impacts us differently than it does younger women or men.

"Your body isn’t broken. It’s different. Fasting in your 40s, 50s, and beyond requires a customized, hormone-friendly approach."

Fasting helps by:

1. Reducing insulin resistance

2. Supporting cellular repair and autophagy

3. Enhancing mental clarity and fat metabolism

But if overdone or poorly timed, it can:

1. Raise cortisol (your stress hormone)

2. Disrupt sleep and thyroid function

3. Trigger fatigue, cravings, or irregular cycles

Women in midlife are already navigating hormonal shifts. Adding intense fasting without adequate support can backfire.

1. You feel jittery, anxious, or wired

2. You crash in the afternoon or sleep poorly

3. Your cycle becomes irregular (if still menstruating)

4. You stop losing weight or feel inflamed

5. You feel cold, tired, or mentally foggy

The Keto-Green® Fasting Framework

Dr. Anna’s unique approach to fasting focuses on alkalinity first, fasting second. That means:

1. Start your day with greens and healthy fats before extending your fast

2. Incorporate key minerals and fiber to stabilize cortisol

3. Avoid fasting on high-stress days or during PMS if you’re still cycling

4. Break your fast with protein, healthy fats, and greens to avoid insulin spikes

This creates metabolic flexibility without crashing your adrenals.

Fasting + Hormones = Strategy, Not Starvation

Fasting is a powerful tool — but only when paired with nourishment, rest, and smart timing. You are not meant to fast like a 25-year-old fitness bro. You are wise, evolving, and your body deserves care.

"Once I added minerals and adapted my fasting to my cycle, everything shifted. I stopped feeling burnt out and finally lost the belly bloat." — Gina, 49
