Keto Diet for Women Over 40

Why Keto is Different for Women Over 40

As women enter their 40s, hormonal changes, metabolism shifts, and insulin resistance can make weight loss more challenging. The Keto Diet, a high-fat, low-carb approach, offers a way to manage these changes while promoting fat-burning and energy stability.

Hormonal Shifts & Metabolism Slowdowns

As estrogen and progesterone levels decline, the body stores more fat, especially around the abdomen.
Insulin sensitivity decreases, making it harder to regulate blood sugar and burn fat efficiently.
Keto’s low-carb approach helps stabilize blood sugar and reduce cravings, leading to sustainable weight loss.

Menopause & Keto – Balancing Fat-Burning and Hormones

Higher healthy fats (avocados, nuts, olive oil) support hormone production.
Protein intake prevents muscle loss, which is crucial for metabolism.
Electrolytes & hydration combat keto flu and reduce fatigue.

6. How long does it take to see weight loss results on keto?
