How do menopause and ageing affect weight?
Many people find that their weight changes after the age of 50 and that it becomes more difficult to maintain a stable weight or lose weight over time. This is likely due to a combination of ageing, hormonal changes, reduced muscle mass, changes in body composition and sometimes a lower level of physical activity.
As we age, muscle mass gradually decreases if it is not actively maintained through physical activity, particularly strength training. Because muscle tissue contributes to the body's energy expenditure, energy requirements may decrease slightly over time. If eating habits remain unchanged while energy requirements decrease, it may become easier to gradually gain weight.
Research suggests that the gradual weight gain often seen in middle age is primarily due to an interaction between ageing, energy balance, physical activity and lifestyle habits rather than menopause itself. However, menopause appears to affect body composition and how body fat is distributed. As oestrogen levels decrease, a greater proportion of body fat tends to be stored around the abdomen rather than the hips and thighs, while muscle mass may also decrease.
Sleep, stress, lifestyle habits, medicines and genetic factors also affect changes in weight. Weight changes after 50 are therefore usually the result of several interacting factors rather than a single biological change.
This does not mean that weight loss becomes impossible after 50. With an appropriate diet, regular physical activity and a focus on preserving muscle mass, many people can achieve both weight loss and improved health later in life.
How does menopause affect the body's fat distribution?
During menopause, the body's fat distribution changes. Falling oestrogen levels have been linked to increased fat accumulation around the abdomen and an increase in visceral fat, which is fat stored around the internal organs.
Before menopause, a greater proportion of body fat is often stored around the hips and thighs. As oestrogen levels decrease, body composition gradually changes, meaning that more fat tends to be stored centrally on the body. At the same time, other age-related changes occur, such as reduced muscle mass and changes in energy balance, which can also contribute to changes in weight.
Visceral fat is biologically active and produces hormones and signalling substances that can affect inflammation, metabolism and the body's sensitivity to insulin. An increased amount of abdominal fat has therefore been linked to a higher risk of conditions including type 2 diabetes, cardiovascular disease and other metabolic diseases.
However, it is important to remember that changes in body composition during menopause vary between individuals. Regular physical activity, strength training, good sleep and healthy eating habits can help counteract some of these changes and support good health over time.
How should you eat to support weight loss after 50?
There is no single diet that suits everyone, but research and international dietary guidelines recommend a diet focused on vegetables, fruit, pulses, wholegrains, fish, nuts and unsaturated fats. This type of diet has been linked to better cardiovascular health and can also make sustainable weight loss easier.
For women living with overweight or obesity who are losing weight, it becomes particularly important to ensure sufficient protein intake and regular strength training to reduce the loss of muscle mass and maintain strength and function.
For women after menopause, bone health also becomes an important factor. Calcium and vitamin D help maintain normal bones and are found in foods including dairy products, fortified plant-based alternatives and oily fish. Supplements may be appropriate for some people, particularly in cases of confirmed deficiency or insufficient intake.
The most important thing is not to follow a specific diet, but to create eating habits that are nutritious, sustainable and adapted to the individual's needs, health and life circumstances.
Guidelines for eating habits
To support sustainable weight loss while preserving muscle mass, strength and bone health, the following are recommended:
Prioritise protein-rich foods at every meal
Protein helps increase feelings of fullness and preserve muscle mass during weight loss. Examples include fish, eggs, dairy products, pulses, tofu and lean meat.
Choose fibre-rich sources of carbohydrates
Wholegrain products, pulses, vegetables, fruit and berries provide important nutrients, support gut health and can contribute to feeling fuller for longer.
Include healthy fats in your diet
Unsaturated fats from foods such as nuts, seeds, avocado, vegetable oils and oily fish are part of a nutritious diet and contribute to better cardiovascular health.
Ensure sufficient intake of calcium and vitamin D
Calcium and vitamin D are important for maintaining normal bones, particularly after menopause and during weight loss.
Why is physical activity important after 50?
Physical activity is an important part of both healthy ageing and sustainable weight loss. As we age, muscle mass gradually decreases if it is not maintained through regular activity, which can affect strength, balance, function and body composition.
Strength training is particularly valuable after the age of 50 because it helps preserve and build muscle mass. For people who are losing weight, strength training can help reduce the loss of muscle mass while also improving strength and physical function. Regular strength training also has positive effects on bone health and can help reduce the risk of osteoporosis later in life.
Cardiovascular exercise and everyday movement are also important for health. Walking, cycling, swimming and other forms of physical activity can improve fitness, cardiovascular health and wellbeing while contributing to increased energy expenditure.
For most people, a combination of strength training, cardiovascular exercise and regular everyday movement is recommended. Together, these measures can help support weight loss, preserve muscle mass and promote good health throughout life.
Frequently asked questions about losing weight after 50
What type of exercise is best for weight loss during menopause?
There is no single type of exercise that is best for everyone. For most people, a combination of strength training, cardiovascular exercise and everyday movement is recommended. Strength training is particularly important after menopause because it helps preserve muscle mass and strengthen bones, while cardiovascular exercise contributes to improved cardiovascular health and increased energy expenditure.
Do I have to count calories for the rest of my life to lose weight?
No. Recording food intake or counting calories can be a valuable tool for increasing your understanding of portion sizes, eating habits and energy intake. For many people, it can be particularly helpful at the beginning of weight loss or if weight loss has plateaued.
At the same time, it is rarely necessary to count calories for the rest of your life. Many people manage to maintain their weight loss by establishing sustainable eating habits, regular meals and routines that work in everyday life. Nutritious food with sufficient protein, fibre-rich foods and good satiety can make it easier to regulate energy intake without having to record every meal.
The most important thing is to find a strategy that works in the long term. For some, this means continuing to record their food intake, while others prefer to focus on eating habits, portion sizes and the body's hunger and fullness signals.
Why is it common to gain weight during menopause?
Many women find that their weight changes during menopause. However, research suggests that the gradual weight gain that often occurs in middle age can largely be explained by ageing and changes in lifestyle habits rather than menopause itself.
However, the hormonal changes during menopause appear to affect body composition and fat distribution. As oestrogen levels fall, a greater proportion of body fat tends to be stored around the abdomen rather than the hips and thighs. At the same time, muscle mass gradually decreases with age if it is not maintained through regular physical activity.
Sleep difficulties, stress, reduced physical activity and changing energy requirements can also contribute to weight changes during this period. Changes in weight are therefore often the result of several interacting factors rather than hormonal changes alone.
Although changes in body composition are common during menopause, weight gain is not inevitable. Regular physical activity, strength training and healthy eating habits can help support both weight management and long-term health.
Can medical treatment help me lose weight after 50?
For some people, modern weight loss medicines can provide valuable support by affecting the body's systems for hunger, fullness and energy balance, which can make weight loss easier and help maintain the results over time.
Whether medical treatment is appropriate is determined through an individual medical assessment that takes into account factors including weight, health conditions, any associated conditions and previous treatment attempts. For the best possible results, medical treatment is usually combined with healthy eating habits, regular physical activity and other lifestyle changes.
Many people over 50 can achieve significant health benefits from moderate weight loss, regardless of whether treatment involves medication.
