That 13% figure? It's actually for children only, not all adults. For obese kids, other data shows ~40% instead of 47%. And surprising twist: childhood obesity has leveled off or dropped in many groups. https://s.fitbodyscience.com/MYdLZE

The breakdown

The study says 13% of kids have fatty liver, but the post stretched that to all people.

The study linked in the post actually found that 13% of children worldwide have NAFLD, not all people, so that claim is an overstatement. For obese children, the linked study found 47%, but other research puts the number closer to 40–41%, so there's disagreement. The trend of rising prevalence and higher rates in males is well-supported by both the linked study and other research. However, the claim that childhood obesity is still increasing is contested — some studies show it has leveled off or started to decline in many groups.

Bottom line

So while the general picture of rising NAFLD in kids and higher rates in boys is accurate, the 13% number only applies to children, and the exact rate in obese children varies across studies.

ReliabilityThe evidence mostly supports this with some caveats
