The major hypothesis is that African Americans have a smaller mass of the most metabolically active organs (ie, liver, spleen, kidneys, heart, and brain)—and therefore a lower proportion of body mass as high-metabolic-rate (HMR) tissues—than do whites.
Which is the more metabolically active tissue fat or muscle?
Muscle is more metabolically active than fat, which means that muscle burns more calories than fat while you are at rest.
Which of the tissue has low metabolic rate?
The masses of four high metabolic rate organs (i.e., liver, brain, heart, and kidneys) and three low metabolic rate tissues (i.e., skeletal muscle, adipose tissue, and residual mass) are presented in Table 2.
Is lean tissue metabolically active?
Lean tissue is the most metabolically active body tissue, and muscle mass, a predominant component of lean tissue, appears to be lost over time in those with SCI at a rate exceeding that of the able-bodied population [3,4].

Why is muscle metabolically active?
Many fat-burning enzymes are found in muscles. More muscle means you burn more calories. Muscles demand more fuel and need more calories for support. For every pound of muscle you add, your body will consume an additional 50 calories each day.
Which muscles burn the most calories?
Strength training becomes especially important as we get older, when our metabolisms tend to slow down. One way to stop this is to add some strength training to your workout at least a couple of times a week. The largest muscles (and therefore the largest calorie burners) are in the thighs, abdomen, chest, and arms.11 мая 2007 г.
Which body tissue is the least metabolically active?
Four metabolically active organs, brain, liver, kidneys and heart, have high specific resting metabolic rates when com- pared with the remaining less-active tissues, such as skeletal muscle, adipose tissue, bone and skin (13).
Which organ contributes most to basal metabolic rate?
Compared with the resting metabolic rate of skeletal muscle (14.5 kcal · kg−1 · d−1), the metabolic rate of heart and kidneys is 33-fold higher (440 kcal · kg−1 · d−1), of the brain is 18-fold higher (240 kcal · kg−1 · d−1), and of the liver is 15-fold higher (200 kcal · kg−1 · d−1) (1).
Which organs use the most energy?
It is well established that the brain uses more energy than any other human organ, accounting for up to 20 percent of the body’s total haul. Until now, most scientists believed that it used the bulk of that energy to fuel electrical impulses that neurons employ to communicate with one another.
What is lean tissue in the body?
Lean body tissue is comprised of many essential parts, including organs and bones. The muscles, tendons and ligaments are also considered lean body tissue. … Being lean means you are within a healthy weight range with adequate muscle tissue to support your activity level.
What are the benefits of having lean muscle tissue?
The benefits of lean muscle tissue go beyond increased metabolism. Increased bone density, increased flexibility in the tendons and ligaments, increased hormonal stability, increased longevity and vitality, reduced risk of injuries, reduced risk of illness, and the list goes on …
Where is a lean part of your body?
Lean body mass is simply everything that’s not fat. This component includes your bones, organs, muscles, ligaments, tendons and fluids.
What is metabolically active?
Tumor cells are usually metabolically active (hungry) and will take up more sugar (glucose) than normal cells. The more glucose the cells take up, the more the cells light up. PET scans take advantage of this difference to help distinguish active from inactive tumor masses.
