Please check this video for info on the BMI, I know I use this term a lot but I wouldn’t want people to get me wrong, I do believe the BMI is not 100% accurate as one of the users said under the video:
BMI is NOT an accurate measurement of one’s health for many reasons, heavy weight champ would be considered “obese” and does not take in account of fat/muscle mass ratios. A skinny person who eats regularly exercises a lot who happens to fall below the 18.5 threshold would be considered “underweight”. I know people, teachers back in High School with pretty fucked up BMIs who are very quite healthy. I know people who are “Underweight/Overweight” according to BMI who are WAY healthier then me.
