Why Low Testosterone in Men and Menopause in Women Cause Weight Gain and Fatigue
As men and women age, hormonal changes significantly impact their metabolism, energy levels, and overall well-being. Men experiencing andropause (male menopause) and women going through menopause often struggle with weight gain and fatigue, even if their diet and lifestyle remain unchanged. But why does this happen?
Hormones Control Metabolism
Testosterone and estrogen play vital roles in regulating metabolism and maintaining lean muscle mass. As these hormones decline:
Men: Lower testosterone leads to muscle loss and a slower metabolism, causing fat accumulation, particularly around the abdomen.
Women: Reduced estrogen shifts fat storage to the midsection and slows down calorie-burning processes.
Insulin Resistance and Increased Fat Storage
Both men and women become more insulin-resistant with age, meaning the body struggles to process carbohydrates efficiently. This leads to higher blood sugar levels and increased fat storage, especially in the midsection.
Loss of Muscle Mass = Slower Calorie Burn
Muscle is metabolically active, meaning it burns more calories at rest. As testosterone and estrogen decline, muscle mass decreases, reducing the number of calories burned throughout the day. Without adjusting diet or increasing resistance training, weight gain becomes inevitable.
Cortisol and Stress-Related Fatigue
Hormonal shifts also affect stress hormones like cortisol. Chronic stress and poor sleep—common during menopause and andropause—lead to increased belly fat and persistent exhaustion.
What Can Be Done?
The good news is that weight gain and low energy aren’t inevitable. Hormone replacement therapy (HRT), strength training, a high-protein diet, and stress management can help men and women regain control of their metabolism, energy, and overall health.
