Many women find that despite no changes to their diet or exercise, the scale begins to climb during perimenopause. This “menopausal middle” isn’t just about vanity; it’s a significant shift in your metabolic flexibility.
The transition into menopause involves more than just the end of menstruation—it is a total hormonal recalibration.
As estrogen levels decline, your body becomes naturally more insulin resistant. Estrogen previously helped regulate how your cells utilized glucose. Without it, your body is more likely to store carbohydrates as visceral fat (the dangerous fat around your organs).
As we explored in our guide on Sarcopenia, aging leads to a natural loss of muscle mass. Because muscle is metabolically active tissue, losing it lowers your Basal Metabolic Rate (BMR), meaning you burn fewer calories at rest.
Menopause is a stressful time for the body. High levels of cortisol (the stress hormone) signal the body to hold onto fat, particularly in the abdominal area. Poor sleep—common during menopause—further spikes cortisol and hunger hormones like ghrelin.
To combat insulin resistance, shift your focus from “low calorie” to “high nutrient density.”
Cardio is great for heart health, but Resistance Training is the gold standard for menopause. Building muscle is the only way to “fix” a slowing metabolism. Aim for two to three sessions of strength training per week focusing on compound movements.
Using a Continuous Glucose Monitor (CGM) can be a game-changer during this phase. It allows you to see exactly which “healthy” foods are spiking your blood sugar and contributing to fat storage.
It’s important to address this shift early. According to the Mayo Clinic, excess weight during this period significantly increases the risk of:
