You might have the exact same weight today compared to five years ago, yet experience changes in the way your body feels. Carrying grocery bags might get harder, getting up off a low chair could be a strain, and you may find that lifting weights becomes tough to do.
This is the reason why a relevant question arises here – is it possible to lose muscles without losing weight?
Yes, it is. Muscle changes along with changes in body fat and fluid balance can occur independently of body weight. Such changes in women at the age of 40 might be accompanied by perimenopause, which makes it hard to determine the influence of hormonal changes on muscle loss.
The problem of muscle loss in women past 40 requires understanding that although menopause can affect muscle changes, it is just one of the influencing factors. Also, there are some methods of preserving strength during the process of aging.
The Scale Doesn't Tell the Whole Story
Muscle is living tissue which requires constant renewal and repair. The body manufactures muscle proteins in response to nutrition and exercise, while simultaneously destroying protein which is old and/or damaged.
However, over time this balance may shift unfavorably in either direction. Failure to maintain muscle growth at an adequate pace compared to muscle destruction may result in gradual loss of muscle tissue. Lack of physical activity, poor nutrition and age-related changes may cause such imbalance.
There is also the matter of difference between muscle mass and muscle strength. While the first term denotes the volume of muscle tissue a person has, the second refers to their ability to generate force. Thus strength may decrease even despite minor changes in muscle mass because of changes in muscle quality and nervous system ability to utilize muscle.
The age-related decline in muscle strength and mass may lead to a disease called sarcopenia, which is related to deteriorating muscle function. However, weakness in people who are over 40 doesn't necessarily mean sarcopenia.
For women and muscle loss, the bigger question is not simply whether muscle mass changes with age, but what influences those changes and how they can be managed.
What Changes When Menopause Enters the Picture?
Oestrogen is most commonly associated with reproduction; however, oestrogen acts on numerous organs, among them skeletal muscle.
Oestrogen levels change during the period of perimenopause and continue to be decreased after menopause compared to those seen during the reproductive years. Whether these hormonal changes affect muscle protein turnover, muscle regeneration, muscle quality and performance has been explored by scientific studies.
One systematic review focused on the relation between oestrogen and female skeletal muscle aging concluded that post-menopausal females have smaller muscle mass and strength than pre-menopausal females. Yet, there are conflicting results concerning the effect of oestrogen deficiency and hormonal therapy.
It is an important issue as the differences between pre-menopausal and post-menopausal women may not prove that menopause leads to the reduction in muscle mass and strength. Other factors, such as aging, exercise and diet, play the same role.(1)
Additionally, there was another cross-sectional study that showed the effects of the menopausal transition on the women’s lean soft tissue mass, muscle quality, and protein balance. Nonetheless, it did not show any differences in the muscle mass or knee-extension strength among the groups of women. It is worth noting that the cross-sectional design does not confirm causality between the studied variables.(2)
Taken together, the evidence suggests that the menopausal transition may be an important period to pay attention to muscle health, without assuming that every woman will experience substantial muscle loss.
Why Two Women of the Same Age Can Have Different Muscle Health
Let us take the example of two women that are 48 years old.
While one does regular strength training, consumes adequate food intake and is active all day long, the other sits most of the day and is not active.
This difference could possibly cause different muscle state, although the women have equal levels of hormones in the body.
There are several reasons for this.
Movement is necessary to keep muscles strong. Walking is good for heart and overall fitness, but the muscles also require resistance to sustain and develop strength. Without adequate resistance, muscles may slowly lose their abilities.
Food is necessary for muscle maintenance. Proteins provide amino acids that allow for muscle construction and maintenance. Insufficient protein or energy consumption can make muscles harder to maintain.
Recovery influences your physical activity. Lack of sleep, such as when you experience night sweats, can cause fatigue and unwillingness to work out. Any chronic sleep issues require separate consideration.
Diseases can cause weakness. Certain illnesses, malnutrition, medication use, and sedentary lifestyle may influence the functioning of muscles. Do not always consider your unexplained weakness caused by menopause.
To conclude, muscle wasting during menopause does not depend only on hormonal changes. There are other factors, some of which can be managed.
What Actually Helps Preserve Muscle After 40?
Instead of aiming for a specific figure on the scales, strive to keep the capabilities that your body has.
Motivate your muscles to grow
Strength training is one of the most effective ways to retain muscle mass after 40. Weight training, resistance band work, or even exercise with body weight helps muscles get accustomed to the load.
It can be chair squats, wall push-ups, resistance band rowing, and exercise with dumbbells depending on the fitness level of the person. It is recommended to start from easier exercises and increase the difficulty of training as you get stronger.
According to experts, adults need at least two days a week of muscular strength activities along with aerobic exercise. In case there are joint or weakness problems or medical issues, consult a specialist before starting any new workout regimen.
Make protein a regular part of your meals
Protein powders are not necessary for the maintenance of muscles. There are many sources of protein in our daily diet, including dal, beans, chickpeas, soy, milk, curd, eggs, fish, and meat.
The inclusion of a source of protein in your main meals will ensure that you fulfill your nutritional requirements. The requirement varies from person to person depending on factors such as body weight, level of activity, food habits, and health. Women with any form of kidney problems need individual advice.
It is also essential that your total diet be adequate. A diet that keeps you malnourished will find it difficult to conserve muscle.
Treat recovery as part of your routine
Resting is not wasting time. Your body requires rest after strenuous physical activities, while sleep disturbance over a prolonged period of time will have an effect on the energy and exercising.
Try to stick to a constant sleeping pattern. If you have problems with hot flashes, night sweats, or insomnia disturbing your sleep on a regular basis, you should consult a healthcare provider about it.
Don't overlook changes in strength
If you experience difficulties with normal activities, note the difference. Weakness that appears to persist, a reduction in strength, and even problems with balance may require professional evaluation.
A physician can examine your symptoms and overall health and decide if you need any tests.
What Does the Research Say About Exercise During Menopause?
A systematic review and meta-analysis from 2023 analysed 27 randomised controlled trials that included 1,989 females aged 40-60. The study evaluated the non-medical means of prevention of sarcopenia such as exercises, vitamin D and protein intake.(3)
The meta-analysis revealed that exercises had positive impact on lean body mass, handgrip strength and knee extension strength. Resistance exercises demonstrated a positive impact on the lean body mass but it was rather insignificant. The evidence regarding the impact of protein intake on muscle strength was inconclusive due to the lack of research in this field.
These conclusions prove the effectiveness of exercising as a method of muscle maintenance during menopause years. However, it does not mean that all kinds of exercises will have the same impact. The results are different depending on the kind of exercises, the frequency of training and other individual factors.
Do You Need Supplements to Prevent Muscle Loss?
Absolutely not. Nutritional supplementation may assist in compensating for particular deficiencies, but they will not take the place of resistance exercise, proper nutrition, and the assessment of any unexplained weakness.
Protein supplementation can be useful if one's dietary sources do not suffice, while vitamin D can be recommended only if there are deficiencies or if the person does not get enough of it through diet alone. Menopausal hormone replacement is not advisable only to protect from muscle loss.
Women navigating menopause can also explore Health etc Women’s Health Gummies as part of their overall wellness routine during this stage of life. However, supplements should complement, not replace, adequate protein intake, regular strength training and other habits that help maintain muscle strength after 40.
The decision about using hormones should be based on symptoms, medical history, possible risks and benefits, and personal objectives of treatment.
Thus, a diet-first strategy, strength training, and consultations with a doctor are good ways to keep your muscles healthy.
Conclusion
Muscle loss in women over 40 years of age is not merely a tale of hormone decline. Age, exercise, diet, sleep, and other health issues have an effect on how muscles develop with time.
The fact of menopause may make it even more important for you to take note of your strength levels, but it certainly does not make muscle loss inevitable. The right amount of exercise, proper nutrition, and recovery can help you maintain your strength levels for years to come.
