The chart below from the American Council on Exercise (ACE) is one of the most commonly used body fat charts.

Essential Fat means the minimal amount of fat required for survival. Anything less than this amount would mostly likely result in organ failure, but even approaching this amount of body fat is dangerous. Even bodybuilders only approach this range during competitions then maintain a higher body fat percentage the rest of the time.
Body fat is essential to survival because fat protects your internal organs, provides necessary energy stores in times of need, and more.
Aim for the Fitness range if you’re goal is to get healthy and look in the mirror with pride.
