All models are wrong, but some are useful. The same is true for the body mass index. In general, people with a higher BMI have a higher chance of getting obesity-related illnesses than those with a BMI in the 18-25 range. But of course, there are exceptions like the one you mention. That's no reason to discard the entire BMI, because it does work in many ...

Skin becomes a better conductor of electricity in response to physiologically arousing stimuli which can be external or internal. Increased sweat increases skin conductivity. This is known as the Skin Conductance Response (SCR) - also known as the Galvanic Skin Response (GSR). (See this Massachusetts Institute of Technology faq page). Another name for GSR is ...

BMI is absolutely NOT a good indicator of health. At least not on its own. It is made up of two measurements only: height and weight. Height is a stable property, and a person cannot do anything about it (nothing physiological and permanent, at any rate). Body weight, however, is comprised of different types of tissues in the body, most notably fat and ...

Consider this ideal weight calculator for example. For a 25 yo male with a height of 9'6'' (289 cm), the optimal weight should be around 342 - 462 pounds (155kg - 210kg). By the way, the tallest man ever was only 8'11'' (272cm) tall (see here). You might want to read about BMI

Let's not conflate two different problems with BMI here. One the one hand you can have a low body fat percentage and still have a high BMI, but that only applies to body builders who exercise at a near professional level. Such a person will not get wrongly diagnosed by his or her doctor of being overweight. So, this shouldn't be a problem, however, as Carey ...

1. You gain weight by consuming more calories than you spend (National Heart, Blood and Lung Institute). 2. If you just consume more calories and you do not start with resistance training, you will convert most of the excessive calories into the body fat rather into bigger muscles, so you will appear fatter (skinny fat) and not "bigger," more muscular, ...

In short: You can have a high BMI (weight in kg/height in m squared) due to: Excessive fat Large muscle mass developed by training "Large frame size," which is genetic, and includes thick bones, relatively lot of muscle mass ad large internal organs. With this large frame, you can have a high BMI without excessive fat, but for BMI as high as 30.4, you would ...

Background: Basal Metabolic Rate is the minimal rate of energy expenditure per unit time by endothermic animals at rest. Several BMR equations exist but the most notable one was the Harris-Benedict equation (revised 1984), which was created in 1919 and was the 'best' until 1990 until The Mifflin St Jeor Equation. These equations use the same factors: P ...

Yes, although your success will depend on many factors. The best way to gain muscle mass is by lifting heavy weights. You will also need to make sure you eat enough, especially enough of protein. How much mass you gain and how quickly depends on how you work out, and also on your genetic make up. Some people gain muscle easier than others. There is a lot ...

As well as any other measurements it doesn't say much on it's own. You need to use it along with other personal details (and measurements) to get some meaning of it. One of the problems with BMI is that muscle weighs more than fat, so athletes (specially the ones that practise sports that rely on strength) tends to break the BMI meaning. It work well in ...
