Why metabolism changes during the menopause
The menopause is a natural stage of life in which the ovaries gradually reduce their hormone production. The decline in oestrogen and progesterone in particular influences numerous bodily functions – including energy balance. Many women notice during this time that their body feels different: weight is gained more easily, energy levels fluctuate, and familiar lifestyle habits no longer seem to deliver the same results as before.
The link between hormones and metabolism is well researched. Oestrogen affects not only the reproductive organs but also muscle mass, fat distribution, insulin sensitivity and even the bones. When oestrogen levels fall, this has noticeable consequences for the whole body.
What actually happens in the body?
Basal metabolic rate and muscle mass
Muscle mass naturally decreases with age – a process known as sarcopenia. During the menopause, this process often accelerates. Because muscles use energy even at rest, their loss also reduces the basal metabolic rate. In other words: the body needs fewer calories than before, even with the same level of activity.
Changes in fat distribution
Before the menopause, women tend to store fat around the hips and thighs. With hormonal changes, fatty tissue is more often deposited in the abdominal area. This so-called visceral fat is metabolically active and may increase the risk of cardiovascular disease, type 2 diabetes and high blood pressure.
Insulin sensitivity
Oestrogen influences how well body cells respond to insulin. When hormone levels drop, insulin sensitivity may decrease. As a result, blood sugar rises more easily, and the body is more inclined to store excess energy as fat.
Thyroid and stress hormones
The thyroid gland can also show changes during this phase of life. In addition, many women react more sensitively to stress – elevated cortisol levels can further affect metabolism and encourage cravings as well as abdominal fat.
The menopause and weight gain: not an inevitable fate
Moderate menopausal weight gain is widespread, but not inevitable. Studies show that hormones alone are not responsible for the extra kilos – it is the interplay of a lower basal metabolic rate, altered muscle mass, sleep quality, stress and lifestyle. Knowing these factors makes it easier to take targeted action.
Typical observations during this phase of life include:
- Weight gain of about 0.5 to 1 kg per year, often regardless of calorie intake
- Increase in waist circumference
- Changes in hunger and satiety
- Reduced exercise tolerance
- Fluctuating energy levels throughout the day
What women can pay attention to
Adjust nutrition – do not change it radically
Strict diets are rarely helpful during the menopause. They can further slow the metabolism and reduce muscle mass. A balanced diet with a focus on protein and sufficient fibre tends to be more beneficial.
Recommended foods include:
- Protein-rich foods such as pulses, fish, eggs, dairy products or lean meat
- Plenty of vegetables and fruit for vitamins, minerals and fibre
- Wholegrain products instead of highly processed carbohydrates
- High-quality plant oils, nuts and seeds
- Adequate fluid intake, preferably water and unsweetened teas
Sugar, alcohol and highly processed foods can have a stronger effect on blood sugar and should be consumed more mindfully.
Use exercise purposefully
Physical activity is one of the most effective ways to support metabolism during the menopause. Strength training in particular helps to maintain or build muscle mass – and thereby keeps the basal metabolic rate stable.
A sensible combination might include:
- 2 to 3 strength training sessions per week
- Regular endurance activity such as brisk walking, cycling or swimming
- Mobility and balance exercises, for example yoga or Pilates
- More everyday movement: stairs instead of the lift, short distances on foot
Sleep and stress management
Sleep disturbances are common during the menopause and can place an additional strain on the metabolism. Too little sleep affects the hormones leptin and ghrelin, which regulate hunger and satiety. Chronic stress can also contribute to weight gain through elevated cortisol levels.
Helpful measures include:
- Regular sleep times
- Reducing screen time in the evening
- Relaxation techniques such as breathing exercises, meditation or progressive muscle relaxation
- Realistic daily planning and breaks
Do not forget bone health
As oestrogen levels fall, the risk of osteoporosis increases. An adequate intake of calcium and vitamin D, together with regular weight-bearing exercise, can help maintain bone health.
When medical support is advisable
Not every change during the menopause can be addressed through lifestyle alone. A medical assessment may be useful if:
- weight gain is significant and unexplained
- symptoms such as severe fatigue, sleep disturbances or low mood affect daily life
- there are signs of thyroid disorders or metabolic conditions
- blood pressure, blood sugar or blood lipid levels become imbalanced
In a medical consultation, individual risks can be assessed and suitable measures discussed – from nutritional advice to exercise recommendations and medical treatment options, where appropriate.
Conclusion
The menopause brings real changes in metabolism – this is biologically explainable and not a personal failing. Supporting the body during this phase with adapted nutrition, regular exercise, good sleep and stress management can contribute significantly to well-being. Small, consistent adjustments tend to be more sustainable than short-term diets or extreme training plans.
The menopause is not an illness but a new phase of life – with challenges, but also with the opportunity to establish healthy habits for the long term.
