⚖️ How a Woman’s Body Changes After 40
Understanding your body helps you choose a smarter diet.
Here are the most common biological changes that occur after 40:
-
Slower Metabolism – Your resting metabolic rate decreases, meaning your body burns fewer calories at rest.
-
Hormonal Shifts – Estrogen and progesterone levels fluctuate, often leading to weight gain (especially around the belly).
-
Muscle Loss – Sarcopenia (age-related muscle loss) starts around 40, reducing calorie burn.
-
Bone Density Decline – Calcium absorption drops, increasing osteoporosis risk.
-
Insulin Sensitivity Changes – Your body becomes less efficient at processing sugar.
That’s why women over 40 benefit most from a balanced, high-protein, fiber-rich diet that stabilizes hormones and supports metabolism.
