> His body fat hovers between 5% and 6%

Either the journalist hasn't a clue, or they were given false information by the person the story is about

Body fat at 5-6% for an extended period of time is decidedly _not_ healthy.

Looking at his pictures I would estimate him at around 12-14% BF. Go on google and search "5% body fat", the difference between what he looks like and what 5%-6% BF would look like is stark. People often get BF % very wrong so I wouldn't be surprised if that was the case.

Moreover, while achieving a sub-10% body fat is achievable (see bodybuilding weigh-ins), it KILLS libido, energy, and general vitality / well-being.

Is there a way I can test for this at home?
