CONFORT-FEMININ How does menopause affect metabolism?

Hot flashes, broken nights, a waistline that grows for no apparent reason... Menopause is not just a matter of hormones shutting down: it is an upheaval that profoundly reshapes the way the body uses energy. Understanding this mechanism is often the first step toward navigating this transition more easily.

Menopause: a gradual hormonal upheaval

Menopause is officially defined as the absence of periods for 12 consecutive months. But it does not happen overnight: it is a gradual process that develops over several years, generally between the ages of 45 and 55. It relies on a finely orchestrated dialogue between the brain (the hypothalamus and pituitary gland) and the ovaries. Every woman is born with a limited ovarian reserve that gradually runs out over the course of her cycles. As the fifties approach, this reserve becomes very low: the ovaries respond less effectively to signals from the brain, and the production of estrogen and progesterone drops significantly.

Why metabolism slows down during menopause

This is one of the least-known mechanisms, yet one of the most tangible in everyday life: estrogen regulates metabolism and the distribution of fat in the body. Before menopause, it naturally promotes fat storage around the hips and thighs (the so-called gynoid body shape). When estrogen levels fall, basal metabolism slows down: the body mechanically expends less energy at rest, and body composition changes, with a tendency to store fat around the abdomen (the so-called android body shape).

In practical terms, this means that, with the same diet, these hormonal changes can lead to gradual weight gain. This usually remains moderate (around 2 to 5 kg over several years): it is not so much the amount that changes as the distribution of fat, which explains why the waistline can increase even when overall weight remains stable.

Sleep, stress and blood sugar: underestimated metabolic factors

Metabolism and sleep are more closely linked than you might think during this period. The body becomes more sensitive to blood sugar fluctuations, and poorly regulated blood sugar during the day can lead to nighttime awakenings. Choosing regular meals that are not too sugary toward the end of the day can therefore support both sleep and metabolism.

Chronic stress also plays a role: it keeps cortisol levels high, which can worsen certain symptoms (hot flashes, fatigue, weight gain) and further slow metabolism. Finally, the liver, which helps eliminate hormones, deserves support: when it is overloaded, estrogen remains in circulation for longer, which can intensify certain discomforts.

Move to preserve your metabolism

Physical activity becomes particularly important during menopause: it supports metabolism, helps limit abdominal weight gain, and preserves muscle mass - a key point, since muscle consumes the most energy at rest. Moderate, regular exercise (walking, cycling, swimming) combined with strength training is especially recommended to counterbalance this natural tendency.

Nutrients to support the transition

Certain nutrients deserve particular attention during this period: vitamin D, which is essential for bone health and emotional balance, and magnesium, which it needs to be properly absorbed by the body. Among plants, hops (including its patented Lifenol® extract) has been studied extensively: its phytoestrogenic action may help reduce hot flashes. A clinical study showed a notable reduction in hot flashes after 6 and 12 weeks of use compared with a placebo. Adaptogenic plants such as ashwagandha may also support the body in dealing with the prolonged stress that weighs on this period.

Key takeaways

Menopause is a physiological transition that reshuffles metabolism, often more than it causes weight gain. Diet, sleep, physical activity and stress management remain the fundamental factors. Dietary supplements can support this balance alongside an overall healthy lifestyle.
