Natural bodybuilding sensation Jeff Seid is focused on nutrition, aiming to pack on the pounds while away from competitions. In a recent Instagram post published on February 26, 2025, he walked fans through his bulking diet that allowed him to add 30 pounds in just four months.
Jeff Seid‘s claim to fame came courtesy of his model-esque physique. His aesthetics, sharp conditioning, and impressive proportions have made it easy for him to excel as a bodybuilder. Fans have long credited him for keeping a ripped physique throughout the years.
He further solidified his standing in the sport back in 2024, laying claim to a Natural Men’s Physique Olympia victory. He’s always offering fans useful nutrition advice, too, as he recently unveiled the go-to breakfast that keeps him lean and healthy. He has incorporated this meal plan for over 10 years.
While his ‘natty or not’ status has been questioned by names in fitness like YouTuber Derek of More Plates More Dates, Seid stands by never touching performance-enhancing drugs. However, he had plenty to say about the diet he’s using to build his physique while away from the limelight.
