Welcome to Culture Clinic, MedPage Today's collaboration with Northwell Health to offer a healthcare professional's take on the latest viral medical topics.

Norway's World Cup star Erling Braut Haaland reportedly consumes 6,000 calories per day, via foods like organ meat and raw milk -- a diet that has garnered attention given the striker's recent success on the field.

But is a dietary routine like Haaland's actually feasible -- or healthy? It depends on a number of factors, and it's certainly not for everyone, experts told MedPage Today.

Consuming 6,000 calories in a single day, "it's definitely high," Lauren Link, MS, RD, CSSD, assistant athletics director for sports nutrition at Purdue University in West Lafayette, Indiana, told MedPage Today. "But it's not absurdly high in our world."

Link, who also serves as president of the American Sports and Performance Dietitians Association, said that in elite sports, "almost nobody would be eating 2,000 calories," which is the general guidance for the average person. "A very low end would be maybe 3,000," she noted. "And then it's quite common to see [4,000 or 5,000] plus," and even up to 6,000 or 7,000 calories per day.
