10 st (64 kg)*

Weight Loss

“I have struggled with my weight all of my adult life, I have PCOS and every diet I have tried just wasn’t successful.

I have lost over 10 stone and I feel absolutely incredible. I would never have dreamt to have the life that I currently have now.”

“Life before surgery was fake, I had a happy face but was not really happy. I wouldn’t go on lads holidays with my friends or take my kids swimming. 

I have lost over 10 stone and it’s been life changing. I have got my life back. I can now take my kids swimming, go on holiday, do those things that I should have done 10,15,20 years ago.”


5 1/2 stone (35 KG)*

Weight Loss

“Before I had surgery, I’d always yo-yoed with my weight. I was ashamed because of the size I’d gotten to. I was unable to buy the clothes I wanted to wear. I didn’t feel like the person that I wanted to be nor did my reflection match the person I felt inside. 

The surgery with Tonic has absolutely changed my life. I’ve lost 5 and a half stone, and I am more confident and outgoing. 


9st (57kg)*

Weight Loss

“Before weight loss surgery, I couldn’t cope with doing anything strenuous and I couldn’t spend time with my children in the way I wanted to. My eating was out of control, and I had been yo-yoing. 

A year out from surgery, I’m a completely different person. Last year, my body fat percentage was in the morbidly obese category. Now, I’m in the healthy weight category.”

Weight Loss

“I lost 8.5 stone. I feel like one of the gym girls, I have done a 10k this year and I am signed up to Brighton half marathon next year! I chose Tonic because I saw so many success stories online and because of the aftercare package. You have the dietician, the PT, the psychotherapist and the constant support group from others who have had surgery and the team in the office”
