Jaime, a 67-year-old woman from Philadelphia, knows too well the effects of muscle wasting. She says, “I used to be much more active when I was young, but as I’ve aged, I’ve noticed my legs are getting skinnier and I easily get tired. It’s affecting my ability to do daily tasks and enjoy life.”
Experts believe that muscle wasting occurs as a result of changes in the body’s hormones, metabolism, and the way it breaks down protein. As we age, our bodies naturally produce less of certain hormones, such as growth hormone and testosterone, which play a role in maintaining muscle mass. Additionally, our metabolism slows down, making it easier to gain weight and harder to build muscle. This combination of factors can lead to muscle wasting and the development of the so-called ‘skinny fat’ physique.
Debra, a director at a local senior community center, explains, “Many older adults are surprised to learn that they can be ‘skinny fat’, meaning they have a normal or low body weight but still have a high percentage of body fat. This is because their muscle mass is decreased while their fat mass stays the same or even increases.”
So why is it important to address muscle wasting and ‘skinny fat’ in old age? The effects go beyond appearance. Losing muscle mass not only affects one’s ability to perform daily activities, but it also increases the risk of falls and fractures. Furthermore, muscles play a crucial role in supporting the body’s organs and maintaining bone health.
Understanding the causes, effects, and solutions to muscle wasting and ‘skinny fat’ in old age is crucial for promoting healthy aging. By addressing these issues, individuals can take control of their health and maintain a strong and vibrant body well into their golden years.

Aging Changes in Body Shape
It is also worth noting that changes in body shape can be influenced by lifestyle and environmental factors. Poor nutrition, sedentary behavior, and certain medical conditions can all contribute to the development of a “skinny fat” body type. Conversely, maintaining a healthy diet, engaging in regular physical activity, and staying socially active can have a positive impact on maintaining muscle mass and a healthy body shape as we age.
In conclusion, aging brings about a variety of changes in the body, including alterations in muscle mass, bone density, hormone levels, and metabolism. These changes can contribute to the development of a “skinny fat” body type, characterized by a loss of muscle tone and an increase in body fat. However, with proper nutrition, exercise, and medical care, it is possible to mitigate these effects and maintain a healthy body shape as we age.
Causes of Muscle Wasting and ‘Skinny Fat’ in Old Age
In old age, the body undergoes various changes, including changes in muscle mass and fat distribution. This can result in a condition known as muscle wasting or ‘skinny fat’, where individuals have a high percentage of body fat but low muscle mass.
There are several causes that contribute to muscle wasting and ‘skinny fat’ in old age. One of the main factors is the natural ageing process. As we age, our bodies naturally start to lose muscle mass and strength. This is known as sarcopenia, and it can begin as early as our 30s. The rate at which muscle loss occurs can vary from person to person, but it generally accelerates after the age of 60.
Another factor that can contribute to muscle wasting and ‘skinny fat’ is a sedentary lifestyle. Lack of physical activity and exercise can lead to muscle loss and increased body fat. Regular exercise, especially resistance training, can help slow down the muscle loss and even promote muscle gain in older adults.
Other factors that may contribute to muscle wasting and ‘skinny fat’ in older adults include hormonal changes, such as a decrease in testosterone levels in men and estrogen levels in women. Hormones play a crucial role in muscle mass maintenance and metabolism, and their decline with age can affect muscle health.
In addition, poor nutrition and unhealthy eating habits can also contribute to muscle wasting and ‘skinny fat’. A diet lacking in protein, essential nutrients, and calories can impair muscle synthesis and maintenance. It is important for older adults to consume a well-balanced diet that includes an adequate amount of protein and nutrients to support muscle health.
Furthermore, chronic conditions, such as obesity and certain diseases, can also lead to muscle wasting and ‘skinny fat’ in older adults. Obesity and excess body fat can result in inflammation, insulin resistance, and metabolic dysfunction, which can further contribute to muscle loss. Diseases such as cancer, kidney disease, and chronic obstructive pulmonary disease (COPD) can also affect muscle health and lead to muscle wasting.
In conclusion, muscle wasting and ‘skinny fat’ in old age can be caused by a combination of factors, including the natural ageing process, sedentary lifestyle, hormonal changes, poor nutrition, and chronic conditions. Understanding the causes of these conditions can help in developing strategies to prevent or manage muscle loss and promote a healthy body shape in older adults.
Effects of Muscle Wasting and ‘Skinny Fat’ in Old Age
As people age, their muscle mass naturally declines. This loss of muscle mass, known as sarcopenia, occurs at a faster rate in older adults. This can lead to a decrease in strength and mobility, making it more difficult to perform everyday activities, such as walking, climbing stairs, or carrying groceries. Sarcopenia can also increase the risk of falls and fractures, as well as lead to a decrease in bone density.
Additionally, muscle wasting in old age can affect body composition. Older adults with sarcopenia often have a higher percentage of body fat, leading to the ‘skinny fat’ appearance. This is when a person may have a normal or low body weight, but a high percentage of body fat, particularly around the abdomen. This can be problematic, as excess abdominal fat has been linked to an increased risk of heart disease, diabetes, and other chronic health conditions.
There are various factors that contribute to muscle wasting and ‘skinny fat’ in old age. These include changes in hormone levels, decreased physical activity, poor nutrition, and the natural aging process. Hormonal changes, such as a decline in testosterone and growth hormone levels, can contribute to muscle loss and increased fat accumulation. Lack of physical activity and poor nutrition can also contribute to muscle wasting, as well as weight gain.
It is important for older adults to take steps to maintain muscle mass and prevent muscle wasting. This can be achieved through regular exercise, particularly strength training exercises that target major muscle groups. Adequate protein intake is also important for muscle maintenance and repair. Older adults should also focus on maintaining a healthy weight and body composition through a balanced diet and regular physical activity.
Possible Solutions for Muscle Wasting and ‘Skinny Fat’ in Old Age
As we age, our bodies undergo various changes that can lead to muscle wasting and the development of a “skinny fat” physique. This can be a cause for concern as it not only affects our physical appearance but also poses significant health risks. However, there are potential solutions that can help combat these issues.
One possible solution is regular exercise, especially resistance training. Engaging in activities that challenge and strengthen the muscles can help counteract muscle wasting. This can include weightlifting, bodyweight exercises, or using resistance bands. It is important to consult with a healthcare professional or a qualified fitness trainer to ensure that exercises are performed safely and effectively.
Dietary changes can also play a significant role in preventing muscle wasting and achieving a healthier body composition. Consuming adequate amounts of protein is essential for muscle growth and repair. Including lean sources of protein such as chicken, fish, eggs, and legumes in the daily diet can be beneficial. Additionally, consuming a balanced diet rich in fruits, vegetables, whole grains, and healthy fats can provide essential nutrients to support muscle health.
Another solution is the use of hormone replacement therapy (HRT) under the guidance of a healthcare professional. Hormones such as testosterone and human growth hormone (HGH) play a vital role in maintaining muscle mass. When levels of these hormones decline with age, muscle wasting can occur. HRT can help supplement these hormone levels and potentially slow down muscle loss in aging individuals.
In conclusion, combating muscle wasting and “skinny fat” in old age requires a multifaceted approach. Regular exercise, dietary modifications, hormone replacement therapy, and maintaining a healthy weight can all help address these issues. It is important to consult with healthcare professionals to develop a personalized plan that takes into account individual needs and goals.

Why Are My Legs Getting Skinny
Sarcopenic muscle wasting is a condition that occurs when there is a loss of muscle mass and strength, most commonly seen in older adults. This can be due to a variety of factors, including changes in hormone levels, decreased physical activity, and a decrease in the body’s ability to build and maintain muscle.
According to a review by Debra J. Rose, Director of the Center for Healthy Aging and Professor of Kinesiology at California State University, Sacramento, the ageing process can lead to a decrease in the speed at which muscles are replaced with new ones. This can also slow down the body’s ability to repair and recover from muscle damage, which can contribute to muscle wasting.
Additionally, changes in body composition, such as an increase in body fat and a decrease in muscle mass, can also lead to a loss of muscle tone and definition, making the legs appear thinner. This can be further exacerbated by obesity or a sedentary lifestyle, as excess weight and lack of physical activity can cause muscles to become weak and less capable of supporting the body’s weight.
It’s worth noting that muscle wasting in the legs can also be a result of certain medical conditions, such as chronic diseases or conditions that affect the nervous system. These conditions can impact the body’s ability to maintain muscle mass and can contribute to the gradual loss of muscle over time.
Review Date: 7/21/2022
Skinny fat is a term used to describe individuals who may appear thin or have a low body weight but have a high percentage of body fat and low muscle mass. This combination can put them at an increased risk for health problems such as obesity, falls, and loss of independence.
One reason why muscle wasting occurs in elderly individuals is because of a slower rate of muscle protein synthesis. As we age, the body becomes less efficient at building and repairing muscle tissue. Additionally, hormonal changes, reduced physical activity, and poor nutrition can also contribute to muscle loss.
Furthermore, maintaining a healthy diet that includes adequate protein intake is crucial for muscle health. Protein-rich foods such as lean meats, eggs, and dairy products can provide the necessary nutrients for muscle repair and growth.
