RTÉ today announced that Operation Transformation will return on Wednesday, 4th January 2023 at 9.30pm on RTÉ One.

A new group of remarkable leaders and some new faces will feature in this brand-new series, as it continues to inspire the nation to live happier and healthier lifestyles.

This series will follow five leaders from all over the country to take on a health and wellness plan under the careful supervision of four qualified experts with the aim of resetting and kick-starting a new chapter in their lives.

Now entering its 16th series, the show is welcoming some new faces and features to its format.

The show's focus is still very much on overall health but this year will highlight 14 specific health indicators. These include upper body strength, balance, lower body strength and cardiovascular adding to the usual hydration, blood pressure, metabolic age, weight, general health, nutrition, movement, among others.

During the series, Professor Niall Moyna will highlight the importance of everyday movement and how best to utilise outdoor amenities when it comes to daily exercise.

Following a slew of requests from viewers for updates on how previous leaders are getting on since their transformation journey on the show, OT 2023 will be checking in with previous leaders about their experiences since taking part in the show.

Dietitian Sophie Pratt is set to join the panel of experts in 2023.

Presented by Kathryn Thomas, the show will welcome back some familiar faces as well as introduce viewers to some new faces and formats.

Former OT leader Katie Jones will host the brand-new OT podcast, while dietitian Sophie Pratt is set to join the panel of experts.

Pratt will work alongside Dr. Sumi Dunne, Dr. Eddie Murphy, and Karl Henry on our OT panel of experts for 2023.

On joining the new show, Pratt said: "I am delighted to be part of the Operation Transformation team and I am really looking forward to guiding the leaders on their journey. I hope that together we can inspire the general public to make the necessary dietary and lifestyle changes for their own transformation in 2023."

Among other changes as we head in to in 2023, OT will broadcast from Stradbally, Co Laois. Each week the leaders will meet the experts here as they chart their weekly Health Check-In.

In partnership with SVT Activity and Wellness Hub and Laois County Council, the county will host the weekly Ad Break Challenges where OT Fitness Karl Henry will be on hand to get the community moving and the series will aim to boost awareness of health and well-being initiatives in the area.

Also, back for 2023, is Ireland Lights Up. This popular initiative in collaboration with the GAA encourages clubs from the 32 counties to open their grounds and allow people to safely walk under their lights. After a tough couple of years, the GAA and Get Ireland Walking are delighted to invite communities back into the safe outdoor spaces where everyone can get moving at their own pace.

Sport Ireland, The Local Sports Partnerships, and OT will again work to bring communities safely together. With the highlight being the 5K in the Phoenix Park on February 18th, 2023.

Operation Transformation airs Wednesday 4th January at 21:30 on RTÉ One and RTÉ Player.
