BMI is one o0f the most inaccurate body composition measurement methods. It fails to take into account muslce mass and bone density, etc. Skin fold tests are much more accurate. According to my BMI I am classified as overweight yet I am a top 3 placed national fitness model lol
Even when I was oveweight according to the BMI, my doctor was like "Wow, you're so healithy!" The BMI scale doesn't take into account bone structure and metabolism. & for example some of the skinniest people (like my cousin) eat the most but have low BMI, etc
