What Is A Good Lean Muscle Percentage?

Are you looking to lose weight, get lean and toned, look more athletic, or build muscle?

Then the key to achieving your goal is to improve your body composition - which means you need to lower body fat percentage and build lean muscle mass.

Body composition is the ratio of lean body mass (muscle, bone, connective tissue, etc) to adipose mass (fat mass). This is very important for people who want low body fat and gain good muscle tone - to look lean and strong! Too many people only focus on the number you see on the scale every morning. What is more important is your percent body fat and skeletal muscle mass. By achieving and maintaining an ideal body fat percentage and building muscle definition, you will look and feel better, be healthier, and more resilient throughout your life. Bonus - when you have more muscle you can eat more food because your metabolism is higher. The higher your metabolism the more calories you have to eat to maintain your body weight.

So what is the lean body mass definition? And is there a difference between skeletal muscle vs muscle mass?

Lean body mass includes all of your body parts that do not contain fat; also called fat free mass. These body parts include your bones, skin, organs, muscle mass, and body water. Also, skeletal muscle mass is the same as muscle mass, and these terms can be used interchangeably.

Many people just want to see the scale number drop and to lose fat so they will cut calories through a deprivation diet (typically a fad diet) and do countless hours of cardio to burn calories. This will drop the number you see on the scale, but it comes at a cost long term. This strategy will help you lose body fat, but you will lose muscle mass too. Lean muscles are your metabolic engine. Meaning, you will not be able to eat all that delicious food you love so much without building lean muscle!

Unfortunately, men and women do not have the same body fat percentage requirements - they have different body fat percentages based on their biological needs. Women need to maintain a slightly higher body fat percentage than men to keep their hormones and body healthy. The graphic below shows examples of body weight fat percentage by gender.

What Is The Importance Of Lean Body Mass?

Lean body mass is so important. Lean muscle mass is the major engine of our metabolism - meaning the more lean muscle you have the higher your metabolism. Meaning you can eat more and not gain weight!

Having higher lean mass also helps combat illnesses such as diabetes and insulin resistance, and can assist you during your recovery after an illness. Higher lean body mass also ensures your muscles and bones remain strong and healthy as you age.

Comparing Lean Body Mass And BMI

Both lean body mass and Body Mass Index (BMI) can be used as indicators for good health. But your weight alone only reveals how much you weigh and not the composition of what makes up that weight. This leads to the the logical questions,"What's my lean body mass?" Because, knowing how much of your weight is made up of fat and healthy muscle will lead you to make more healthy lifestyle choices.

BMI is calculated using your height and weight but does not account for the composition of your weight. It is a good starting point, but it is incomplete if lasting health is your goal. . Lean muscle mass is more dense than fat mass. Lean body mass is a better indicator of your overall health, and making healthy lifestyle decisions such as eating healthy and getting enough exercise will improve your overall health.
