Many women gain excess weight after the age of 40 as a result For hormonal changesslow metabolism, loss of muscle mass, stress, sleep disturbances, and a decrease in estrogen during the pre-menopausal period often leads to an increase in fat in the abdominal area. Experts confirm that regular exercise, muscle-strengthening exercises, balanced nutrition, and good sleep are all factors that help control weight gain in middle age and maintain general health.
Hormonal changes during perimenopause
According to what was published in Times Now, the hormonal change known as perimenopause, which is the stage that precedes menopause, is one of the most important factors behind weight gain after the age of forty. During this period, levels of the hormones estrogen and progesterone fluctuate and then gradually decrease. Estrogen plays a pivotal role in regulating body weight, metabolism, and fat distribution. As estrogen levels decrease, the body tends to store more fat around the abdomen rather than the hips and thighs.
Metabolism slows with age
Another major reason is the natural slowdown in metabolism. With age, the body burns fewer calories at rest. This means that the same diet that was previously used to maintain weight may now lead to a gradual increase in fat. The solution is not to follow a harsh diet, but to build immunity, so protein intake and sleep regulation must be increased.
Loss of muscle mass
After the age of 30, muscle mass begins to decrease at a rate of between 3 and 8 percent per decade. This process accelerates during middle age. Muscle burns more calories than fat, so losing muscle slows the body’s metabolic rate. As muscle mass decreases and fat increases, women may see changes in body composition, even if body weight does not change significantly. This is why strength training becomes especially important after the age of 40.
Sleep problems and stress
Middle age is often accompanied by high levels of stress and sleep disturbances, both of which may contribute to weight gain. Hormonal changes may affect the quality of sleep, and chronic stress increases the production of cortisol, a hormone linked to the accumulation of fat in the abdominal area. Lack of sleep may also lead to disruption of hunger hormones such as ghrelin and leptin, which increases the feeling of extreme hunger and the desire to eat foods rich in calories.
