Does Muscle Weigh More Than Fat? It’s Complicated

does muscle weigh more than fat

The concept of whether fat weighs more than muscle, or vice versa, depends on the volume of each rather than the materials themselves. A familiar example of this is the trick question: “does muscle weigh more than fat?” The answer is neither, as a pound is a pound regardless of the material. However, a pound of feathers would occupy more space and appear larger and fluffier compared to a compact pound of bricks.

When discussing the weight of muscle and fat, the underlying factor to consider is body size and body composition. It’s important to note that body size or weight alone does not necessarily indicate one’s health. However, there is some truth to the notion that muscle weighs more than fat.

It is possible for someone to be slimmer but weigh more than another person who is lighter, depending on the proportion of non-fat mass (such as muscle, bones, and organs) to fat mass. Here is what you should know about this topic.

Does muscle weigh more than fat?

In terms of volume, muscle does weigh more than fat. Comparing a bowl of fat to a same-sized bowl of muscle, the muscle will be heavier.

However, it’s important to consider more than just weight when discussing muscle and fat. The reason muscle weighs more is because it is denser than fat. When you hold a fistful of muscle, it will weigh more than a fistful of fat due to the compactness of the tissue.

It’s crucial to remember that focusing solely on the number on the scale isn’t as important as understanding the benefits of having more muscle in your body compared to having more fat.The composition of your body, including the ratio of muscle to fat, plays a significant role in overall health and fitness.

How does having more muscles affect your health?

Muscle plays a crucial role in maintaining long-term health and well-being for various reasons.

Firstly, having lean muscle mass can help regulate blood sugar levels and reduce the risk of developing Type 2 diabetes. A study published in PLoS One in 2017 demonstrated a negative correlation between muscle mass and Type 2 diabetes, indicating that higher muscle mass is associated with a lower likelihood of developing the condition. The skeletal muscle in the body is the primary consumer of blood sugar, making it essential for stabilising blood sugar levels.

Additionally, muscle has an immediate and lasting impact on blood sugar regulation. After exercising, the muscles continue to utilise blood sugar more efficiently for up to 72 hours, according to Tim Church, MD, MPH, Ph.D., a professor of preventive medicine at Pennington Biomedical Research Center.

Maintaining a healthy amount of muscle becomes increasingly important as you age. Muscle serves as a significant marker of healthy aging and helps prevent age-related issues like sarcopenia, which is the loss of muscle mass typically observed around age 40 or 45. Preserving muscle mass is crucial for maintaining strength and the ability to perform daily activities independently.

Furthermore, muscle contributes to weight management by increasing the basal metabolic rate—the number of calories burned at rest. While the exact number of additional calories burned by muscle is still debated, it is widely acknowledged that having more muscle leads to a faster metabolism.

Lastly, in terms of appearance, muscle is denser than fat, which means it takes up less space in the body. This higher density allows individuals who gain 10 pounds of muscle to see minimal changes in their physique, while a similar weight gain in fat would be more noticeable.

Overall, muscle provides numerous health benefits, including blood sugar regulation, healthy aging, weight management, and improved physical functionality.

How does excess fat affect you?

While it is often perceived negatively, body fat is essential for survival and optimal functioning. Fat tissue serves several important roles, including regulating body temperature, producing hormones, supporting brain health, and insulating organs, as explained by Church.

According to the American Council on Exercise (ACE), healthy body fat percentages for women typically range from 10% to 31%, while for men, it falls between 2% and 24%. For men over 60, the American College of Sports Medicine suggests a maximum of 25% body fat. However, it’s crucial to understand that lower body fat percentages are often associated with trained athletes and may not be realistic, sustainable, or healthy for the average person. Contrary to common belief, fat is not solely excess energy storage. It is a significant driver of inflammatory markers in the bloodstream. Chronic inflammation, which can result from high levels of body fat, is associated with various conditions such as Type 2 diabetes, arthritis, inflammatory bowel disease, and obesity, as noted by Church.

Furthermore, a higher body fat percentage has been linked to an increased risk of heart problems. Seedman highlights a strong correlation between elevated levels of body fat and cardiovascular disease, along with other health issues.

How to Lose Fat and Build Muscle in a Healthy Way

When it comes to building muscle and reducing fat, strength training is a highly effective approach.

According to Seedman, if you have limited time for exercise, strength training is significantly more impactful. Additionally, you can modify work and rest intervals to incorporate cardiovascular benefits into your strength routine.

To promote muscle growth and fat reduction, Seedman suggests engaging in a full-body strength training routine at least twice a week. It is important to push yourself close to the point of muscle failure during each set, where the last one or two repetitions feel challenging to perform while maintaining proper form.

If your goal is to simultaneously lose fat and build muscle, opt for shorter rest periods between sets (around 30 to 60 seconds) to increase the intensity of your workout. Focus on selecting five to six exercises, with three targeting the lower body and three targeting the upper body. Aim for 3-4 sets of 6-12 repetitions for each exercise.


In conclusion, the concept of does muscle weigh more than fat is a common misconception. While a pound of muscle and a pound of fat both weigh the same, muscle is denser than fat. This means that muscle takes up less space and contributes to a leaner and more toned appearance. When focusing on fitness goals, it’s important to consider body composition rather than just the number on the scale. Building muscle through strength training not only enhances metabolism but also leads to a healthier physique. Remember, it’s the quality of weight that matters more than the quantity.
