⚖️ How a Female Body Changes After 40

Understanding your body helps you eat smarter. After 40, women experience several physiological and hormonal shifts:

Metabolism slows down – You burn fewer calories at rest, making weight gain easier.
Muscle mass decreases – With age, muscle tissue reduces, lowering calorie burn.
Hormonal fluctuations – Estrogen levels drop, leading to fat storage around the belly and hips.
Bone density declines – Calcium absorption decreases, increasing risk of osteoporosis.
Insulin resistance – Blood sugar levels may rise more easily, causing fatigue or cravings.

That’s why women over 40 need a balanced, high-protein, nutrient-rich diet that keeps metabolism and hormones in harmony.
