The World Health Organization assesses a person’s weight based on their body mass index (BMI), which is measured by dividing how many kilograms they weigh by their the square of their height in meters.

The first rationale is that BMI is strongly correlated with weight, but is independent of height. The second rationale is that BMI correctly captures the relationship between weight and height, which implies that the slope of log weight regressed on log height is 2.

While it takes height into consideration, it does not account for factors such as: waist or hip measurements. proportion or distribution of fat. proportion of muscle mass.

Abstract. Introduction: The height-weight difference index (HWDI) is a new indicator for evaluating obesity status. HWDI was calculated as the difference between height and weight. Pearson’s correlation coefficient was used to assess the relationship between HWDI and BF%.

Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases. An example of positive correlation would be height and weight. An example of negative correlation would be height above sea level and temperature.

Yes there is a relationship between age and height. This because the height of a child is not constant, but increases as the child continues to grow. The pattern of growth in children varies from child to child.

As you age, the composition of your body changes. Metabolism and hormonal levels alter, impacting the degree and speed of fat accumulation. Generally, the greatest body weight is found in males and females in the 50-59 age group, and declines gradually after you hit 60.

Big boned means wider bones Measure your wrist to find out if you’re really big boned, since “body frame size is determined by a person’s wrist circumference in relation to height,” according to the National Institutes of Health. More than 5 feet 5 inches tall and wrist size larger than 7.5 inches.

According to the University of Washington, women should weigh 100 pounds for the first five feet of height plus 5 pounds for each additional inch over five feet – plus 10 percent to account for large frame sizes. For example, a large-framed woman who is 5 feet 3 inches tall has an ideal body weight of 127 pounds.

While the common myth remains that muscle weighs more than fat; it doesn’t. One pound of muscle and one pound of fat weigh precisely the same––one pound. Muscle is denser than fat, and as it is more compact within your body, as you gain muscle mass, you end up looking thinner, no matter your physical weight.

Bones can become stronger by resistance training, but they do not grow. Your bones may be a limiting factor in how much muscle mass you can put on. You can’t grow bigger than your frame can support. It is impossible to gain mass, without at least some strenght gain.

5 ways to boost bone strength early

1. Monitor your diet. Get enough calcium and vitamin D, ideally through the foods you eat.
2. Maintain a reasonable weight. This is particularly important for women.
3. Don’t smoke and limit alcohol intake.
4. Make sure your workouts include weight-bearing exercises.
5. Talk with your doctor about your risk factors.

Most skinny guys will gain weight if they eat 3000 calories a day. A guy weighing 55kg with moderate activity levels needs about 2400 calories to maintain his weight. So if he starts eating 3000 calories a day, consistently, he should start seeing weight gain.
