He said yesterday that his training camp on the Gold Coast had whipped him into shape and improved nutrition helped his weight cut.
Lewis, who usually drops around nine kilograms to make the UFC's heavyweight limit of 120.2kg, stripped down and posed behind a towel as he made the grade at 265 pounds.
Hooker (13-7) is moving up to lightweight after spending his first six UFC bouts at featherweight and he looked better on the scale than the gaunt figure he has cut in the past.
The 27-year-old will meet Australian-based Englishman Ross Pearson on the main card (19-13, 1 NC).
Jumeau's opponent was the second-to-last fighter to weigh-in and it looked like he endured a challenging weight cut.
He called for a towel as he climbed on the stage and caused a few laughs when he added: "I was brought into this world naked, I'll weigh in naked."
But he tipped in at 170.5 pounds (77.3kg) and ensured Jumeau's debut will go ahead without a hitch.
American middleweight Derrick Brunson (16-5), who will meet Australian Dan Kelly (13-1) in the co-main event, went straight to the food table after he hit the scale and made a Nutella sandwich.
The only fighter to miss weight was South Korean women's strawweight Chan-Mi Jeon (5-0) as the 19-year-old was 118 pounds (53.5kg), two pounds over the non-title fight weight limit for the division.
Her opponent JJ Aldrich (6-2) accepted the bout anyway and will get 20 per cent of Jeon's show money for her misdemeanour.
The reason for the weigh-ins being held on Friday night when the fights are on Sunday is part of a new regime to help fighters remain in good health while making weight.
Usually if a fight card begins in the evening on a Saturday, local time, fighters can weigh-in early on the Friday morning.
But because this fight card takes place during the day on Sunday, the weigh-ins had to be pushed back and Friday night became the most appropriate window.
There will be ceremonial weigh-ins at Spark Arena tomorrow and the event is free for fans.
