The Body Mass Index (BMI) is an indicator to help people to determine if they might have a longer life span than average, are probably not overweight, are probably overweight, or are obese. The intervals for each are from 17 to 22, 23 to 24.999, 25 to 29.9, and over 30 respectively. Notice that it is between 17 and 22. That is not inclusive but rather a compound inequality statement which is 17 < BMI < 22. Moreover, over 30 is an inequality statement with a positive infinity which is any BMI that is greater than 30, or BMI > 30 which will be written as (30, +∞). Anyway, my BMI will be calculated, and I will explain …show more content…
Remember that one foot is equivalent to twelve inches. Since I am five feet tall, we will multiply five with twelve to get sixty. Now, I am an additional eleven inches taller than five feet, that is, sixty inches. Hence, we will add eleven inches to sixty inches to make that seventy one inches. The formula …show more content…
It’s no guarantee that one will live longer than usual because, due to some misfortune, he may die in an accident one month later. Or he could be a smoker yet he maintains a healthy weight for his height. In other words, the BMI does not take in factors that are detrimental to his health. So, in order for that to work, there would be a need to construct a more complicated formula to take in account of all the possible factors. Between two persons of different height yet have the same weight, the formula doesn’t take notice of the body fat percentage. A good example is an athletes who weighs a lot for his height yet is much fitter and more trimmed. There is a difference between fatty tissue and lean tissue. Somebody could have a very healthy weight yet has so much fat in the belly while is thin in every other area of the body. Or what if a person is so dangerously thin that he has reached a healthy BMI? Also, age is not taken in factor for the BMI formula. What if one is 95 years old and has a BMI of 21, is he really going to live a lot longer now? It is not an effective formula for children either because their bodies are still

    Although I am seventy one inches tall, I want you to notice the H = 71. Although I am 180 pounds in weight, so used this W = 180. Consequently, I plug into both of the values into my formula’s, the BMI= (703* 180)/ (71^2 which is 71 square means that 71 multiplied is 5,041. Now 703*180 is 703 multiplied by 180 equals to 126,540. Consequently, I have the BMI which is = 126,540/5,041. Now with me using this calculation I performed a much longer division of 126,540 divided now by 5,929 it is close to the equivalent 25.10, when you round down it is based on the 2 which is in the thousandths place valued system ( from 0,000 to 0,0049/ and up from to 0,005 to 0.00999).

    Physicians and fitness professionals, among others use body mass index (BMI) as a general gauge of the weight status of an individual. BMI is an easy calculation that uses your height in inches multiplied by your weight in pounds. This is not a completely accurate method for all body types and in the diversity of what type of fat is contained in the body or where the body fat is located.

    Annotated Bibliography: The Global Epidemic Of Obesity

    Obesity is excess weight, occurring when energy intake from food and drink consumption is greater than energy expenditure through body metabolism and physical activity. The cause of obesity lies in the interactions between genetics, the environment, and behavioural factors (Kumanyika & Brownson, 2007). BMI (Body Mass Index) is the most common method for measuring obesity, as it is a sufficiently accurate tool and easy to administer (National Obesity Observatory, 2009). Adults with BMI between 25 and 29.9 are classified as overweight and those with 30+ as obese. BMI measurement for children would be assessed in accordance with growth, and gender characteristics (National Obesity Observatory, 2009).…

    Osteoporosis: A Case Study

    Typically, a healthy BMI is considered to be between 18.5 and 24.9 (kg/m2), underweight people have a BMI under 18.5 (kg/m2), an overweight BMI is between 25 and 29.9 (kg/m2), and obesity is above 30 (kg/m2) (Johansson et al., 2014; Ong et al., 2014). Extensive research is being conducted to determine the effect that a high or low BMI has in regard to risk of fracture. Several studies are in agreement that both a low BMI and a high BMI are detrimental to bone health in women (Compston et al., 2014; Johansson et al., 2014; Ong et al., 2014).…

    Should Obese People Pay Higher Health Insurance Premiums Than People Who Are Not Obese?

    The body mass index (BMI) assesses one’s body weight relative to height. The weight in kilograms is divided by height in meters squared (kg/m^2). It correlates highly with body fat in most people hence is a useful, indirect measure of body composition. According to research carried out by the Centers for Disease Control and Prevention (CDC), with increasing weight the risk of diseases also increases including cancer, stroke, coronary heart disease etc. A BMI between 25.0 and 30.0 is defined to be “overweight” and a BMI of over 30.0 is defined to as “obesity” (30 or more pounds overweight). Overweight and obesity result form an energy imbalance which involves consuming too many calories as compared to the amount of physical activity one does.

    Cardiorespiratory Fitness

    HR across BMI categories of normal, overweight, and obese were significantly higher in unfit than fit women. This is because the heart works harder for unfit individuals. Using body fat measures as a way to determine all-cause mortality in women may not be useful. The only way it could be useful is if cardiorespiratory fitness is considered as well. Cardiorespiratory fitness is strongly and inversely related to all-cause mortality with or without factors such as body fat measures. Low cardiorespiratory fitness in women was an important independent predictor of all-cause mortality. Higher cardiorespiratory fitness was associated with lower deaths within each category of adiposity. Rates of all-cause mortality were significantly lower in fit-normal BMI women than in unfit women within each stratum BMI. Fit women with high BMI, percent body fat, high waist circumference, and high waist-to-height ratio had no greater risk of death compared with their fit-normal counterparts. BMI was not an important way to determine all-cause death in women. I believe additional information may be required to see if this applies to males, adolescents, and…
