That means that 15 pounds of muscle takes up much less space than 15 pounds of fat. So what does this mean for the average person who is looking to stay healthy? But if you are even a little bit athletic, or if you lead a fairly sedentary lifestyle, BMI can be misleading.

Take a star NFL tight end. And when we look at this muscle and body fat levels, his body composition results agree. The muscle mass and percentage muscle mass measurements show an individual with high Skeletal Muscle Mass and low Percent Body Fat The reason his body weight is so high is that more than half of his body weight is made up of muscle.

Although BMI may not be an accurate measurement tool for rich professional athletes, you might be wondering what does this have to do with me.

Sedentary adults working in offices who do not exercise are known to lose Skeletal Muscle mass, especially in their legs. This condition is called skinny fat , and because of our reliance on body weight measurement and BMI, it often goes undetected.

The muscle mass and percentage muscle mass measurements show an individual with low Skeletal Muscle Mass and High Percent Body Fat These individuals are at risk for some of the same health complications as people who are visibly overweight, with BMI values above These health complications can include cardiovascular disease , high blood pressure, diabetes, and more.

It then makes sense that in a Canadian study of 50, people, it was found that a low BMI did not necessarily correspond with a lower mortality rate. Hopefully, by now we have convinced you the importance of using something more advanced than a weight scale or BMI.

Luckily, there are many methods to determine your body composition. Some are quick and easy but provide basic information only. Some are lengthy and expensive and require the assistance of a trained technician to administer a test. This is a method that many people have encountered in their local gym.

Calipers are widely used because they are portable , easy to use, and can be administered by almost anyone as long as they have had proper training and sufficient experience. These results are taken and used in mathematical calculations, which determine the fat mass in your entire body.

Calipers are an example of 2C body composition analysis. Hydrostatic weighing also known as underwater weighing calculates your body fat percentage using you underwater body weight. To get your underwater weight, you first need to expel all of the air in your lungs and then submerge yourself in a pool while sitting on a special scale.

Your underwater weight is compared with what you weigh on land, and these numbers, together with the value of the density of the water in the pool, are put through a series of calculations. These calculations produce your body fat percentage. However, just like calipers, hydrostatic weighing cannot report anything beyond body fat, like skeletal muscle mass, body water, and dry lean mass.

To get a hydrostatic weighing test performed, you will need to make an appointment at a facility such as a university or high-end sports complex that has built a hydrostatic weighing pool and a trained staff. DEXA sometimes abbreviated as DXA , is a medical test that involves lying on a table while a machine sends X-rays through your body and measures the difference in the amount of energy initially sent through the body and the amount detected after it exits the body.

Although DEXA was originally designed to measure bone density, it is now used to measure body fat and muscle mass. Unlike calipers and underwater weighing, DEXA scans have the ability to measure the body segmentally, scanning each arm and the trunk separately in order to accurately measure fat mass, soft lean mass, and bone density in each segment.

In order to get a DEXA scan performed, you will typically need to make an appointment with a hospital or clinic that has a DEXA device. You may need to do some research; because of the cost, not all hospitals and clinics will have a DEXA machine.

Once impedance is measured, body composition is calculated. Unlike other methods, a technician does not always need to be present at a BIA test, and you can use BIA devices with just by following the directions on the device.

BIA devices range widely in quality and accuracy , and you should be aware that not all BIA devices test the entire body. To build more muscle, you must incorporate progressive resistance training, most commonly weightlifting or bodyweight training callisthenics , into your training routine.

Eat protein! The right amount of protein consumption helps increase and maintain lean body mass and has many other benefits, such as healthier hair and skin and building immunity. You can also benefit from protein intake during exercises, primarily if you work out for more extended periods and intense.

When you consume a sports drink that combines carbohydrates with protein, your muscles will use the carbohydrates as fuel and protein as a signal to increase muscle protein synthesis muscle building.

Recovery is an essential part of your workout! Training progress and building muscle happen only when regeneration surpasses the previous ability. This is called supercompensation.

Exercise increases your lean body mass, but it also increases the release of stress hormones. This, in turn, increases the muscle protein breakdown. If you want to minimise muscle protein breakdown, consume enough daily protein.

Get adequate amounts of sleep each night. Sleep is crucial for increasing lean body mass. Try sleeping seven to eight and a half hours for multiple complete sleep cycles of REM. These cycles appear and repeat in approximately 90 minutes — during this time, most regeneration and adaptation occur.

The more cycles you miss, the less recovery you will get. Dieting can help you get rid of unwanted body fat and increase lean body mass, but there is one crucial thing to note.

Extreme diets increase muscle protein breakdown. Besides watc hing your calories, you should also pay attention to increasing your fibre intake. It makes you full for longer and slows the increase of blood glucose after a meal. Black beans, berries, sweet potatoes, and other high-fibre foods are digested at a much slower rate, causing a slow, steady stream of glucose into your bloodstream.

For great meal ideas which are simple to make, check out these recipes from our nutrition experts — they contain lots of protein and fibre to keep you on point in your lean body mass journey. You should aim to keep your diet balanced, learn to listen to your body and see how it responds to different foods.

Monounsaturated fats are found in canola and olive oil , while polyunsaturated fats are found in fatty fish such as tuna and salmon. Of course, these are just general rules of thumb you should abide by.

But there are no one-size-fits-all approaches or a diet that magically works for everyone. To really learn how to get leaner, fitter, and improve your overall health , you should do a DNA test.

It will help you discover your genetic predispositions for things such as your response to carbohydrates, fats, risk of becoming overweight, and even the diet type you should choose!

You also get personalised recommendations to help you keep a healthy weight and improve your wellbeing — based on your DNA only.

A better understanding of these passive and active roles of FFM in the control of energy intake will necessitate the elucidation of peripheral signals and energy-sensing mechanisms that drive hunger and appetite, with implications for both obesity prevention and its management. Some 30 years ago, Gilbert Forbes pointed out that the lean body mass and body fat are in a sense companions, so that in many situations a change in one is accompanied by a change in the other, and usually in the same direction.

Stratified analyses were performed by gender and adjustment was made for physical activity and calcium intake. Univariate multilevel analyses indicated that FFM was significantly positively related to the yr development of both LBMD and LBMC in both sexes.
