“My asthma is dormant and my blood pressure is now under control. My HBA1C dropped from 68 to 41 and my medication has halved. My health has been completely transformed.”
Clare
“My physical and mental health has never been as good. I was just in this cycle of piling on weight. It was just stress and all the rest of it. I put on this weight and I could not shift it and then that had a huge knock-on effect. And then I lost two stones and that’s two dress sizes. I found myself again as a woman. I lost part of my identity as a woman with the weight and she’s back and I love it”
Debbie MacQueen
“It was the same old roller coaster – lose a bit, gain some more, this was going on for some time… I had no energy … But THIS is different, the whole concept of a lifestyle change, the support and the accountability are the big things for me. The ultimate changes that benefit me and grandchildren – I can now play with my grand kids, go to the beach and YEAH I could actually wear a bathing suit and go in the water and swim with them!!!”
Samantha Smith
“I was just in an unhappy place and after I got divorced, I sort of hung on to that weight. It was like a security blanket for a long time. I was really hurting and my joints were aching and I just couldn’t go without medicating. Now, I take absolutely nothing and I don’t have those aches and pains in my joints anymore. When I went under 100 kilos, I thought, oh my god I’ve done it. I thought right away, where do I want to go? Right to the very top of the hill in the woods, there’s a really sunny place where you can just look at all the fields. I just went off straight up a huge hill that I would never have gone up before. As I got there, my god, I was so overwhelmed with emotion and I was so proud of myself.”
Debbie
“My cholesterol and blood pressure are now at normal ranges. It was the same old roller coaster – lose a bit, gain some more, this was going on for some time… I had no energy … But THIS is different, the whole concept of a lifestyle change, the support and the accountability are the big things for me. The ultimate changes that benefit me and grandchildren – I can now play with my grand kids, go to the beach and YEAH I could actually wear a bathing suit and go in the water and swim with them!!!”
Mish Burgess
“I was very good at putting a mask on. I was great at saying I don’t care, I’m fat and happy. I’m always the first to say derogatory words to myself because then nobody else can hurt your feelings if you’ve said the things first. But I was miserable and thought I’m just destined to be a big lass. Then everything changed. I lost like 3 stones in the end. I’ve gone from size 22 to about 16. By the time I finished working with you, I’d dropped from a size 16 to 8. I printed my end picture and the very first picture that I sent to you. The one where I just looked so miserable and old. And I put them side by side on the canvas. It’s the first thing I see when I wake up and the last thing I see when I go to bed. And I don’t want to be that woman anymore. I like this one.”
Tsitsi Danai
“As you grow older, the pounds just tend to pile on despite your best efforts to try and keep it off. I was noticing it in my clothes, my confidence, and you sort of lose yourself. But with all the tools that you gave me, I managed to lose the weight. I lost about 8 kgs by the end of it which I would never have thought I would have done. I went from a size 12 dress size to a size eight. Then I decided there’s no reason why I can’t take this seriously. Some of my friends urged me to join 10k runs and half a marathon. I ran half a marathon in 2 hours, 7 minutes which I would never have done.”
