Can you believe we've reached the end of Operation Transformation 2021? The time has flown by and our incredible leaders have been a constant source of entertainment and inspiration throughout these strange and stressful times.

After an incredible eight weeks of training, cooking, running and talking, our fab five have come to the end of their incredible journey. Tonight at 9:35pm on RTÉ One, they will take their transformations to the catwalk in the much-anticipated grand finale.

As well as revealing the leaders' final weigh-in results, tonight's show will look back at how the amazing socially distant 5k went during their final week.

Ahead of tonight's show, we're looking back at the progress of our 2021 leaders...

Susuana Komolafe

Originally from Lagos, Nigeria, Susuana moved to Ireland with her son and daughter just over 18 years ago.  Adapting to a different culture and lifestyle, her diet changed considerably over the years, and she became fond of her cups of tea and biscuits. She loves her curves, but was conscious of her high blood pressure and ultimately decided that she needed to live a healthier lifestyle to improve her long term health.

During her time on the show, Susuana had trouble adapting to her food plan but with the help of Aoife Hearne, she got her portion sizes under control and even found a way of including some of her favourite foods from home into her meals.

When it came to exercise, a new indoor bike helped the woman make strides forward – even if she was peddling backwards! 

Andrew Burke Hannon

Andrew is 33 years old and lives in his native Clondalkin with his husband Jason and his parents.  Andrew was bullied during his school years, which was extremely difficult for him. During this time he love for Baton Twirling grew, resulting in him becoming a champion. 

Diagnosed with an under active thyroid in his early 20’s, Andrew wants 2021 to be the year that he takes control of his health and wellbeing once and for all.

Working with Dr. Eddie, Andrew tapped into some of the emotions he felt during the years he had been bullied. Eddie encouraged him to work on his habit of seeking reassurance from those around him by reducing his "checking" behaviours.

With renewed confidence, Andrew smashed his fitness goals and was even told to up his calories at one point. Andrew was tasked with running the 5k with none other than Karl Henry himself so we can't wait to see the results.

Paul Devaney

41-year-old Paul Devaney hails from Tuam, Co Galway. He is married to Mary and they have two daughters, Machaela and Katie. Working for a construction company, Paul spends much of his week on the road and has fell into some poor eating habits and a lack of regular exercise. With his family and community 100% behind him, Paul wants to make 2021 his year for change.

Working alongside Aoife Hearne, Paul adapted his meal plan to suit his needs and challenged himself to go "cold turkey" on the sugar in his tea. With his diet on plan and his ankle being looked after by a physio, Paul's next challenge came from Dr. Eddie who asked the father of two to cut down the amount of time he spends on his phone.

Enjoying the time at home with his family, spending time outdoors and getting in some archery, Paul has made huge strides on OT.

Hazel Hartigan

47-year-old Hazel Hartigan, originally from Wexford, settled in Limerick when she married her husband Richard. Hazel has two children, Tommy (20) and Grace (14). They also had twin daughters, who passed away but are never far from their thoughts. Tragically, Niamh was still born and her sister Chloe lived for five years. 

Hazel's dream was always to be a nurse and in 2015 she returned to college and graduated in January 2019.  Working as a full time staff nurse in St. John’s Hospital Limerick, Hazel wants to be fabulous at 48 and 2021 is her year to do it.

With her community and her family behind her, Hazel had plenty of support through workouts whether it be on the road or over over Zoom. As a busy nurse, her schedule has always been hectic but as she works nights and deals with COVID-19 restrictions, Hazel faced a number of challenges. The experts decided to step in and lend a helping hand to keep the leader on track. 

Sharon Gaffney

44-year-old Sharon Gaffney lives in Drimnagh, Dublin, with her three children, 15-year-old Paige and 10-year- old-twin sons, Max and Leo. A divorcee, Sharon is Director of Finance and Organisation Services in the Royal Victoria Eye and Ear Hospital. Running a busy household and working full time has seen Sharon neglect her health and wellbeing but she has decided that 2021 will be the year she gets her mojo back.

Paige has been a big supporter throughout the journey and even offered to join her mum in the 5k. When it came to meal planning, however, Sharon relied on her own parents for support and motivation.

With working from home, homeschooling, and being a hands-on mammy, Sharon has worked hard to stick to her OT plan. We can't wait to see the results of her hard work on tonight's grand finale.

Watch Operation Transformation tonight at 9:35pm on RTÉ One.
