The transformation of Conor McGregor's physique over his last six fights makes for incredible viewing.
McGregor will make his eagerly-awaited UFC comeback in Las Vegas when he faces Donald Cerrone in a welterweight bout.
A division heavier than his last Octagon outing against Khabib Nurmagomedov in October 2018.

McGregor's eyeing fights at lightweight and welterweight as he begins the start of his "2020 season" and ahead of his anticipated return, we've looked back at the evolution of his body type beginning in 2015 when he fought UFC featherweight champion Jose Aldo.
1. Jose Aldo (December 2015) - 145lbs
McGregor looked extremely gaunt as he made the featherweight limit to face Aldo. He re-hydrated on fight night with the Irishman knocking out the Brazilian in 13 seconds to become UFC featherweight champion.

He hasn't fought at featherweight since and will likely never return to the division.
2. Nate Diaz (March 2016) - 168lbs
McGregor fought at the welterweight limit for the first time in his professional career at UFC 196 and jumped up two weight divisions when he took on Diaz on short notice.

Diaz was drafted in after injury forced Rafael dos Anjos out of his main-event bout with McGregor, who succumbed to Diaz's submission skills.
3. Nate Diaz II (August 2016) - 168lbs
McGregor made a swift turnaround to rematch Diaz and continued to campaign at welterweight in order to redeem himself, which he did by outpointing the Stockton slugger in an epic five round war.

4. Eddie Alvarez (November 2016) - 154.4lbs
McGregor made his UFC lightweight debut versus Alvarez as he fought for the 155lbs title. A weight class he has fought previously during his Cage Warriors days.
Arguably his optimum weight, the Dublin man delivered a virtuoso performance to become UFC's first simultaneous two-weight champion.

5. Floyd Mayweather (August 2017) - 153lbs
The mega-lucrative boxing bout between Mayweather and McGregor took place at the light-middleweight division (154lbs) with the MMA star comfortably making weight by scaling in at 153lbs - 2lbs less than what he'd weigh in for a championship lightweight bout in MMA.
6. Khabib Nurmagomedov (October 2018) - 154.5lbs
McGregor weighed inside the lightweight limit for his title bout with Nurmagomedov and he's since admitted that he was drinking "all bleeding week" in the build-up to his submission defeat.
7. Donald Cerrone (January 2020) - 170lbs
While his UFC 246 return fight is a scheduled welterweight bout, McGregor has revealed that he's "underweight" and weighs a little over 160lbs.
