As of my last update, Shaquille O'Neal, often referred to simply as Shaq, is known for his large stature and athletic build. During his playing career in the NBA, Shaq's weight fluctuated, but he was generally listed at around 325 to 350 pounds (147 to 159 kilograms). However, his weight may have changed since then, so for the most accurate information, it would be best to refer to recent sources or official announcements.
