body fat = (1.20 × BMI) + (0.23 × age) – 16.2. Women: body fat = (1.20 × BMI) + (0.23 × age) – 5.4. BMI is a useful way to calculate body fat percentage because you can also use it as a predictive formula if you are trying to figure out your ideal body weight. A 2016 study found that you can use a target BMI to compute ideal body weight. Height: The minimum height is 58 inches (4 feet 10 inches), and the maximum height is 80 inches (6 feet 8 inches). Weight: The minimum and maximum Weight depends on the height and age of the soldier. For example, a 21-27-year-old female soldier who is 5 feet 4 inches tall should weigh between 110 and 144 pounds. Age 17 – 20 Max. A. There is no agreed-upon normal range for body fat, just as there is no ideal body weight. According to the World Health Organization, men ages 40 to 59 should aim for 11% to 21% body fat, while for men ages 60 to 79, the range is 13% to 24%. However, the "right" weight and fat percent for an individual depend upon multiple factors, such as In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. The calculator also provides a result that falls within a certain range, which can be used to determine if the person’s body fat percentage is within a healthy range for their age and gender. For men, the healthy range of body fat percentage is as follows: Essential fat: 2-5% Athletes: 6-13% Fitness: 14-17% Average: 18-24% Obese: 25% or higher . To use U.S. measurements (pounds and inches) to calculate your BMI, apply the following formula: BMI = 703 x weight in pounds/height 2 in inches. For example, if you weigh 125 pounds and are 70 inches tall, this is how you would calculate your BMI: 703 x (125 (70)2) = 703 x (125 4,900) = 703 x 0.0255 = 17.93. According to this research paper, men who are between 20-40 years old with under 8% body fat are considered “underfat”, whereas a “healthy” range is described as between 8-19%. For women in this same age group, any level under 21% is “underfat” and 21-33% is considered “healthy”. According to various sources, the minimum limit of body fat is around 2-5% for men 2 and 10-13% for women. 3 However, that is just the minimum amount. The average adult male body fat percentage should be between 18 and 25%. For women, their percentage of body fat in relation to age should be between 25 and 31%. Also, girls and boys differ in their amount of body fat as they mature. This is why BMI for children, also known as BMI-for-age, includes gender and age. This calculator gives an approximate BMI for children from ages 5 to 18. It will tell you if a child is underweight, at an ideal weight, at risk of being overweight, or is now overweight. The formula to calculate your weight loss percentage is: lbs lost divided by starting weight. Then, multiply the result by 100. So, if your starting weight is 150lbs and you lost 5lbs, you’ve lost 3.33% of your body weight. Note: Please keep in mind, this calculates total weight loss including muscle.
