Testimonials & reviews

Gemma Collins is a British television personality, actress, and businesswoman, best known for her role on the reality series, The Only Way Is Essex.  Gemma started 2025 two sizes down, after just two months using Yazen's Weight Loss app and medication. “It has absolutely changed my life,” she says.

Having tried every diet, Gemma has finally found something she can actually lose weight on. She feels healthier and happier, without that constant noise in her head “You need to eat,  you need to eat.” 

Gemma is keen to share this approach with anyone that suffered their whole life like her - being bullied all her life by the media for being overweight. She will finally be able to live her best life and be free from the upset, stress and turmoil that comes with constantly trying to lose excess weight.

Erica, a London-based photographer with an active career, started her weight loss journey after discovering she had high cholesterol. Despite trying various diets, she struggled to lose the 20-30 lbs she had gained over the years. After joining Yazen, she received comprehensive support, including medication, diet guidance, exercise tips, and emotional support from a dedicated team of professionals. She’s also adopted a healthier lifestyle, incorporating better food choices and regular exercise into her routine.

Alex, a lifelong Londoner, shares her journey with a weight loss programme combining medication and personalised coaching. After struggling with weight gain due to mental health medication, she tried various diets with little success. Thanks to daily support from her YazenCoach and a more balanced approach to food, Alex is finally on the right path. She’s now focused on returning to more challenging hikes, with plans to tackle Mount Kilimanjaro.
