1.Overview of Lean Body Mass
Everything in your body, excluding body fat, makes up lean body mass.1 Organs, blood, bones, muscles, skin, and any other body part that has mass but is not fat make up your lean body mass. As a side note, skeletal muscle makes up roughly 35% of body weight for women and 42% for the average adult male.
Lean Body Mass = Body Weight – (Body Weight x Body Fat %)
To arrive at this equation, your body weight in pounds is subtracted from your body fat percentage in pounds. (Nuijten et al. 2022)E
2.Why lean body mass is a more meaningful indicator of health
Here are a few important reasons to maintain a lean body mass. (Zanovec et al. 2009)
Lean Body Mass Helps Fight Obesity
Lean body mass and basal metabolic rate (BMR), or how many calories you burn while at rest, are connected. Unlike fat cells, which require energy in the form of calories even when at rest, muscles do. Therefore, if you have lean muscle tissue, you will burn more calories daily and be less likely to gain weight. Obesity aggravates several chronic conditions, such as non-alcoholic fatty liver, metabolic syndrome, cardiovascular disease, chronic systemic inflammation, and metabolic syndrome. A scientifically validated technique for measuring body composition, including weight, lean muscle mass, and fat, is 3D body scanning.
Gaining Lean Body Mass Aids in Healing from Illness or Disease
The body needs more protein to heal when it is ill or diseased. The muscle breakdown fulfils the increased protein need since our regular food frequently cannot meet our protein needs. Less muscular people will have a more challenging time coping with the demands brought on by the illness. It is recognized that muscle loss affects both the survival rate and the rate of cancer recurrence. Patients with lung cancer who lost lean body mass due to the disease and treatment had a higher recurrence rate and a worse prognosis than those who could retain it.
Prevent Diabetes
Lean body mass can prevent diabetes and insulin resistance because it helps the body remove glucose from the blood and maintain normal blood sugar levels. The development of insulin resistance is the initial stage of diabetes. It happens when the insulin that the pancreas secretes after a meal with a lot of sugar loses its capacity to encourage the muscle to absorb glucose from the blood. High blood sugar levels arise from this, which might cause diabetes. Researchers from the UCLA School of Medicine discovered that greater muscle mass was linked to better insulin sensitivity and a lower chance of getting diabetes in a significant study including over 13,000 patients over six years. In addition, they discovered that insulin resistance decreased by 11% for each 10% increase in skeletal muscle mass.
Your Chance of falls and Fractures is lower if you have a Lean Body Mass:
Reduced lean tissue is linked to poor balance, an increased risk of falls, and fractures, particularly in the lower-leg muscles. According to a 2015 American Society for a Bone and Mineral Research study, those with less muscle mass were 2.3 times more likely to fall and break a bone, such as a hip, collarbone, leg, arm, or wrist. The most devastating effect of falling is a hip fracture, which not only carries a significant mortality risk in the first year after the injury but also raises mortality risk for up to 10 years. 3D body Scanner is beneficial in capturing images of falls and fractures in our body.
Keep bones healthy and strong
Lean body mass has been demonstrated to maintain bone strength and health in older men and women. It has also been established that greater muscle mass is a reliable indicator of better bone health. Numerous studies have revealed a beneficial relationship between muscle size and bone density and strength, in addition to the fact that muscle contraction exerts stress on the bone that stimulates healthy bone remodelling. Researchers discovered a link between older men’s weaker and thinner bones and lower skeletal muscle mass levels in the Mediterranean Intensive Oxidant Study. Maintaining proper muscle mass and function is necessary to keep your bones strong and healthy as you age.
3.The difference between weight loss and fat loss
Although “weight loss” and “fat loss” are sometimes used interchangeably, there is a slight distinction between the two. Reducing your whole body weight, including muscle, water, and fat loss, is called weight loss. In terms of weight loss, fat loss refers to weight loss from body fat. Fat loss is a more focused and healthy objective than weight loss. Fat loss is a more focused objective and a better course of action. Losing muscle while losing weight can be harmful. A person’s general health depends heavily on their power level, which aids in correct blood sugar control and cholesterol management. Since you often burn more calories when you reduce fat, no muscle loss exists. (Bell et al. 2017)
When you lose weight, both muscle and fluid density is rapidly lost. It has an additional impact on your body’s fat levels, and you can even start to lose healthy fats. As a result, a person’s body mass decreases, and they risk getting sick. Losing weight may result in a slowed metabolism, increased risk of injury, exhaustion, deterioration of neuromuscular function, and possible consequences on emotional and psychological states. Additionally, it may result in negative alterations to body composition. A toned body and a significant decrease on the scale are two indicators of good weight loss. Having your body composition evaluated can also confirm that the weight loss you are experiencing is healthy. You can appropriately lose weight by eating a balanced diet containing carbs, protein, and fat and exercising regularly.
4.The potential health risks of having a low lean body mass
Here are some potential dangers of being underweight: (Lee et al. 2018)
Malnutrition
If you are underweight, you may need to eat more nutritious foods containing essential nutrients to sustain your body. That might result in malnutrition. Malnutrition can have a range of long-term effects on your health, some of which may be apparent to you or the people around you. You can experience symptoms such as fatigue or a lack of energy, frequent illness or difficulty recovering from an illness, irregular or missing periods in women, hair thinning or loss, dry skin, or dental problems.
In a Japanese study, the eating patterns of underweight women with and without a motivation to lose weight were contrasted. They discovered that overweight women who desired to lose weight had less healthy eating practices than fat women who did not. If you are underweight and your low BMI is brought on by an unbalanced diet or a condition that impairs nutrition absorption, you may be more likely also to be malnourished. Anaemia or a lack of vital vitamins can result from malnutrition. Deficiencies in nutritional absorption might also result in anaemia.
Osteoporosis
Low body weight may increase your risk of osteoporosis and inadequate bone mineral density (BMD). A study that examined the BMD of 1,767 premenopausal women discovered that 24% of those with a BMI of 18.5 or below had poor BMD. Among participants with a BMI more significant than 18.5, only 9.4% showed poor BMD. According to the study, underweight people are more likely to develop osteoporosis.
Heightened potential for surgical complications
According to one study, those who undergo total knee replacement surgery when underweight had a higher risk of developing infections than people who are not underweight. While they could not pinpoint the causes, they theorized that malnourished people’s wound-healing capacities are inferior to those of people with a normal BMI. The group with low preoperative haemoglobin was also discovered to be skinny. The results imply that being underweight can impact your body’s capacity to heal wounds, though additional research is needed to confirm this. (Bell et al. 2017)
Reduced immunological response
A recent data assessment discovered an association between elevated infections and being underweight. The researchers acknowledged their difficulty in determining whether this results from being underweight or if the underlying causes are more to blame. For instance, malnutrition might result in weakened immunity and malnourished individuals. More research is required to comprehend the relationship between weight and immunological function fully.
Infertility
Low-BMI women are more likely to experience amenorrhea, which is the lack of menstruation, and other menstrual cycle disorders. Anovulation, or the lack of ovulation, may be indicated by irregular or skipped menstrual cycles. Infertility may result from persistent anovulation.
5.How to increase lean body mass through strength training and proper nutrition
Building Muscle: The Importance of a Balanced Diet and Workout Routine
Protein-rich diets with minimal saturated fat content are among the finest foods to help you gain muscle. Nevertheless, include both fats and carbohydrates. You’ll need a balanced diet and a solid workout routine for maximum results. If you want to gain lean muscle, you must maintain a nutritious diet and engage in regular exercise. Exercise is crucial to pushing your body to its limits, but your growth will continue with the proper dietary support. Protein-rich foods are essential for growing muscle, but energy must also come from carbs and fats. If building lean muscle is your goal, prioritizing regular exercise and increasing your daily calorie intake from foods that support muscle growth should be your top goals. The main focus while improving one’s physique is frequently on increasing muscle. Adding muscle mass will improve your lean body mass, give your muscles more definition, and give your frame the proper amount of bulk and size. It requires time, perseverance, and long-term dedication to build muscle. While gaining significant power may seem complicated, most people can produce substantial force with the proper workout regimens and diet. (Volek et al. 2013)
The Science of Muscle Growth: Protein Synthesis and Resistance Training
Skeletal muscles are made up anatomically of parallel cylindrical fibres that contract to generate force. This muscle contraction makes all of a person’s movements outside the body possible. The amino acids, or protein building blocks, in your muscles, are continually renewed and recycled by your body. You will lose muscle mass if your body eliminates more protein than it adds. If net protein synthesis is balanced, there is no discernible change in muscle size. And finally, your muscles will expand if your body stores more protein than it expels. The secret to gaining muscle mass is to boost protein synthesis while reducing protein oxidation. Resistance training’s main objective is muscular hypertrophy, acquiring more muscle mass. The production of hormones like growth hormone and testosterone, as well as the availability of amino acids and other nutrients, all play a role in growing muscle. Resistance exercise and consuming enough protein and other nutrients are your main tools for accelerating your body’s rate of protein synthesis, which is essential for the growth of new muscle tissue. (Volek et al. 2013)
6.How to use vis body 3d body scanner accurately measure and track lean body mass
The demand for a practical, secure, and reasonably priced tool for estimating body size, shape, and composition has increased as the rate of obesity worldwide rises. According to recent studies, a three-dimensional 3D body scanning machine has shown promise as a viable substitute for measuring body fat and determining the likelihood of developing metabolic syndrome. This device, often known as a body scanner, uses digital methods to capture the surface geometry of the human body. Body scanning is a non-contact, quick, and precise densitometry technique for measuring body composition and fat. This system computes anthropometric characteristics such as segmental volumes, body surface area, waist and hip circumferences, and sagittal abdominal diameter. Body scanning, therefore, offers more thorough measures than conventional anthropometric instruments. (Lu et al., 2019)
Frequently Asked Questions
Why is having a lean frame necessary?
In particular, maintaining a healthy muscle mass helps stop the thinning or weakening of bones. The risk of falls and fractures in older persons increases by frailty and osteoporosis in later life. The benefits of increasing muscle mass include better bone density and strength.
What distinguishes fat loss from weight loss?
Weight loss is different from fat loss, which is the term used to describe weight loss that is specifically brought on by losses in fat mass. Tracking fat loss with your body weight is less efficient than using a skinfold calliper or body fat scale.
What are the health risks associated with low lean body mass?
It is a crucial shortcoming in the area because it has been demonstrated that low LBM is linked to a higher risk of cardiovascular events, diabetes, metabolic syndrome, extended hospital stays, and mortality in the general population.
Does weight lifting help you gain lean muscle mass?
Strength training has several advantages, including an increase in lean body mass, an improvement in metabolic rate, an increase in bone density, a reduction in the risk of injury, and the ability to replenish muscle tissue typically lost as people age.
