He continued, telling host Vernon Kay that the band’s previous reunion efforts were challenging and a “difficult environment”.
“It would be incredibly unhealthy for us to do it,” he said.
“We’d take a massive step backwards in our lives. And to come away from that then, there’d be a lot of work on rebuilding ourselves individually to the strong people that we feel we are now.”
Keating formed pop band Boyzone in 1993 with fellow members Stephen Gately, Michael Graham, Keith Duffy and Shane Lynch.
The group went on to achieve global blockbuster success, including three New Zealand No 1 hits - No Matter What in 1998, and both I Love the Way You Love Me and You Needed Me in 1999.
The band went on hiatus in 2000 after members indicated they wanted to pursue solo careers.
The band re-formed in 2007 and has continued to reunite intermittently.
Co-lead singer Stephen Gately died aged 33 from acute pulmonary oedema resulting from an undiagnosed heart condition in 2009.
The quartet will play two London shows at Arsenal’s Emirates Stadium in June, their first live performances since 2019.
“We all have our own lives and careers away from the band, but we can come back for that week,” Keating said.
“It’ll be spectacular. We’ll put on all the fireworks and make it magic. And there’ll be tears, but we’ll go out on a high and that’ll be our final chapter written.”
Last week, Keating brought out Duffy and Lynch to sing Picture of You on his BBC One special, Ronan and Friends: A New Year’s Eve Party.
Viewers took to YouTube to express their delight at seeing the bandmates sharing the stage again.
