Quick Answer

There is no “Tom Kennedy” connected to Conor McGregor. The name that keeps showing up next to McGregor’s in searches is almost certainly a misspelling of Tristin Kennedy — the sports nutritionist who has managed McGregor’s diet and weight cuts for nearly a decade. Kennedy took over McGregor’s nutrition full-time during the UFC 246 camp in January 2020 and has remained a core member of his fight team ever since. So if you were looking for the Kennedy behind McGregor’s transformations, you’ve found him: Tristin, not Tom.

Who Are Tom Kennedy and Conor McGregor?

Let’s start with the blunt part: no public figure named Tom Kennedy has any documented relationship with Conor McGregor — not as a teammate, not as an opponent, not as family, and not as staff. Searching the pair together returns almost nothing except articles and interviews about Tristin Kennedy, McGregor’s nutritionist. The confusion is understandable; the two names differ by a single letter, and Tristin Kennedy is not a household name the way McGregor is.

So who is the real person in this story? Conor McGregor is the Irish former two-division UFC champion — the biggest box-office draw in mixed martial arts history, famous for his 13-second knockout of José Aldo and his 2017 boxing superfight with Floyd Mayweather. Tristin Kennedy is the specialist behind the scenes who made sure McGregor’s body could survive the brutal weight cuts that built that career.

Kennedy came into McGregor’s world through veteran MMA nutritionist George Lockhart, a former Marine and Ultimate Fighter veteran. After McGregor’s 2018 loss to Khabib Nurmagomedov, Kennedy began working with him under Lockhart — and by the time McGregor prepared for UFC 246 against Donald Cerrone in January 2020, Kennedy had taken over the nutrition program entirely. In an ESPN interview, Kennedy described the job as “seven-days-a-week work”: daily nutrition plans, supplementation guides, cooking, attending every training session, observing, and collecting data on McGregor’s metabolism.

His philosophy, in his own words: “I can guide the man, but I can’t eat the food for him.” Kennedy says consistency is the whole game — “When he focuses on something and gets down to it, he’s the most consistent man there is.” That mindset powered the lean, powerful physiques McGregor brought to camps from 2020 onward, with Kennedy repeatedly telling the press that McGregor was in the best shape of his life.

One more possible source of the “Tom Kennedy” mix-up: there is a retired UFC middleweight named Tim Kennedy, who shared the UFC 178 card with McGregor back in September 2014 — both men even won $50,000 bonus awards that night. Tim is not Tom, and he never trained with McGregor either. The man actually in McGregor’s corner for nutrition remains Tristin.

He calls McGregor the “most consistent man there is” when locked in.
  • 2021–2025: Kennedy stays with McGregor through a long, turbulent stretch: back-to-back Poirier losses, years of inactivity, business ventures, and McGregor’s brief March 2025 bid for Ireland’s presidency, which he withdrew from in September 2025.

Latest Updates

As of October 2026, the McGregor–Kennedy partnership continues into its eighth year. The most recent chapters of their story are defined by McGregor’s rocky return to the Octagon. In July 2026, after a five-year absence, McGregor fought Max Holloway in a rematch at UFC 329 at the T-Mobile Arena in Las Vegas — and the comeback fell apart early, with McGregor injuring his knee in round one and losing by TKO. Reports described a torn ACL and meniscus.

The defeat left McGregor at 38 years old with one win in his last five fights, on the final fight of his UFC contract, and his fighting future uncertain. It is a sobering turn for a man who once held two UFC belts at the same time. Kennedy’s role through this period has been about keeping McGregor’s body as prepared as possible while the fighter’s public life — including a November 2024 civil court ruling against him, an unsuccessful appeal in July 2025, and a short-lived political run — pulled him in every other direction.

In recent October 2026 interviews, McGregor himself has been reflecting on his career, crediting relentless work over raw talent for his success — the same “consistency breeds success” message Kennedy has preached about him for years. Whether there is one more camp left in the McGregor–Kennedy story is, as of this writing, an open question. Watch McGregor’s camp announcements rather than rumors: when a real comeback begins, Kennedy’s name will be among the first you hear.
