As estrogen fluctuates in perimenopause and declines in menopause, several things happen simultaneously: Insulin resistance increases Visceral fat storage becomes easier Muscle mass gradually declines Resting metabolic rate slows Sleep becomes more disrupted Cortisol becomes more reactive Insulin resistance alone can change everything
Low IGF-1 Frailty, sarcopenia, poor wound healing, lower bone density
This is where research gets exciting
