BMI Lies

BMI is based on the assuption that man grows equally in both height and weight at all ages, but the truth is far from that. We grow weight faster in our first year of life and again during puberty than at any other age and that is out of biologic necessity. BMI is based on your weight and height. In general we have always viewed a certain grouping of weight as acceptable for a certain height, but where it is flawed is that not all weight is equal. Yes, a pound of muscle and a pound of fat both still weigh a pound, they look dramatically different on your body and the ratio of fat to muscle can throw off the BMI number considerably. Just like diet and exercise is not black and white, your perfect weight is not either. Yes, I understand that makes it confusing.

So what is a better indicator? 

Your body fat %. 

Body fat is what causes the problems with your health and causes the bulges that you do not want to see in the mirror so doesn't it seem logical to focus on how much of that you have?

Also, it can be tested with various methods at different costs so you can find the method that works with your experience and budget. 

How do you determine your health and fitness?
