Patrick Ferrari

Weight Loss of 24kg in 4 Months with Consultations in the Clinic

View all

“That’s it. 4 months separate the photo from the left to the right. And despite the fact that I am not active on social media, I could not let this moment pass in blanc, especially because my story can inspire friends that don’t believe that they can achieve their goals. I want to thank my wife Rogeria Alves for being the base for my motivation. She made me believe that I could achieve my goal because at the beginning I didn’t believe in myself.

Secondly, I would like to thank the professional Karline Porter, from Britzke Nutrition that does an incredible work helping people to achieve their goals. I lost 24kgs (4stones) and gain my self-esteem and confidence without a doubt.”  Patrick came to the Harley Street, London Clinic.

Dionizia Vieira

Weight loss of 20kg and Fatty Liver Improvement

View all

It all started when I went to visit a friend and she told me about the Britzke Clinic, I found her results wonderful.

‘Until then, I was very unsatisfied with my weight gain, I practised exercises but with no results. I was with over than 80 kg, so I decided to seek help. I went to my first appointment with Fernanda and she was very nice and very professional. In the first few days, I was very insecure with myself because I had never done a diet in my life. But finally, I decided to give myself a chance. I prepared, I organized, I bought all the food from the meal plan and I started with this adventure. In the​ ​follow-up appointment, I was super happy because, in a month, I lost 4 kg of fat, I was super excited! Fernanda’s orientation was working. I began to intensify in physical activities, I ran a marathon Hackney Half Marathon, I was feeling very well. In total, I’ve lost 20kg and a lot of visceral fat. The goal now is to gain more muscles and move on to the definition. Thank you, Fernanda, for the super professional that you are.’

This story is truly inspiring.

It shows the powerful impact of a personalized diet combined with guidance and precise tests.

This brave little girl from Ireland has faced significant challenges since birth. Her mother, exhausted from superficial treatments and doctors who didn’t address the root cause, sought my help.

She used to rely on antibiotics and struggled with restless nights due to constant itching.

After receiving personalized treatment and following a carefully tailored diet, she completely transformed!

The difference is incredible.

We know that treating the cause, not just the symptoms, is key.
