Your weight hasn’t changed. Your waist has. And your scale may be hiding what’s really happening after 40.
Here’s what most women don’t realize:
You can lose muscle, gain body fat, and experience changes in body composition without gaining much weight at all.
And during perimenopause and menopause, hormonal changes can contribute to shifts in where your body stores fat.
That’s why I don’t automatically tell women to eat less.
I want to know what’s actually changing.
Here are four things I evaluate:
1. Waist circumference and body composition — Is central fat increasing while lean mass changes?
2. Muscle and strength — Are you maintaining the muscle that supports your metabolism?
3. Glucose and HbA1c — What is happening with blood sugar regulation?
4. Triglycerides, HDL and blood pressure — What do they tell us about your cardiometabolic health?
And I interpret those findings in the context of your sleep, nutrition, activity, medications and hormones.
The number on the scale is not the whole story.
After 40, understanding your body composition can be more useful than simply chasing a lower weight.
Comment MARKERS and I’ll send you my After-40 Body Composition Checklist — the key measurements and labs to discuss with your clinician.
