Given the fact that it doesn’t distinguish between lean body weight and fat weight, why is body mass index so widely used to determine ideal body weight?
When I started seriously exercising a number of years ago (lifting weights and cardio), I gained 20+ pounds and dropped 2 waist sizes in my pants. I'm not muscle bound, but do have a lot more muscle now then when I started. According the BMI chart for my height and weight, I'm borderline obese, yet in reality I'm quite fit. At an annual physical my doctor pulled out the BMI chart, looked at me again and said "well, that obviously doesn't work for you."
What's a better way to measure/guage fitness or appropriate weight? Is it solely by measuring % of body fat?
