LIKE BMI, THIS DOESN’T WORK FOR PEOPLE WITH A LOT OF LEAN MUSCLE BECAUSE IT’S BASED ON ASSUMPTIONS ABOUT BODYFAT: Your Neck Size Could Be a Signal For Hidden Health Problems.

A thick neck might project strength, like that of heavyweight boxers or rugby players, but studies suggest it could signal a concerning health issue.

BMI, which divides weight by height to estimate body fat, doesn’t always tell the complete story. A competitive bodybuilder might have a high BMI, but clearly isn’t obese. This is where neck circumference offers additional insight.

Research shows that people with larger necks relative to their body size face increased risks of several serious health conditions. The connection lies in what neck size reveals about fat distribution, particularly in the upper body.

Again, bodybuilders have big necks, but not much fat. Of course, maybe I’m just in denial because I have an 18.5″ neck.
