About Kirsten

I am a working Mum. I also have 17 years' experience as a health promotion research scientist at the University of Cambridge.

As a senior research scientist at the Centre for Diet and Activity Research at Cambridge University, I helped more than 2000 children, teenagers and adults in the UK and USA to improve their diet, get active and lose weight.

Over nearly two decades working to improve people's health, I have learnt that every family is different. Every solution needs to be different too. Off the shelf diets and programmes do not work in the long term.

I thought I had worked out how to be healthy but then I had children and I had to learn all over again.

This is why I work one-on-one with Mums worried about their weight or their weight or their child’s weight. We work together to make a plan unique for you and your family. This means weight loss can be healthy, stress-free and can last

There are normally hidden causes for weight gain. I can help you find yours and reverse them for good. 

Why I care


I was overweight as a child. Being overweight ruled my life.

I knew it didn't need to be this way, which is why I dedicated my life to studying weight loss.

I want to share the secrets I have learnt to save you or your child from feeling like I did.

I can help you build a better relationship with yourself so you can lose weight and keep it off.

Kirsten's Qualifications

I have a Bachelor of Arts (BA), Masters of Arts (MA) and research Masters (MPhil)  from the University of Cambridge. My PhD from the MRC Epidemiology Unit, University of Cambridge, centred on child and adolescent health behaviours. This involved fieldwork in Southern India and the UK and measurement and analysis of diet, body weight and physical activity in over 1000 young people.

I am also a qualified Health Coach, specifically a Certified Transformational Nutrition Coach (CTNC) and a member of the UK Health Coaches Association.

Kirsten's Experience

As a Senior Scientist at the MRC Epidemiology Unit, University of Cambridge, I designed and led multiple health promotion projects for children and young adults. These projects included a large government funded clinical trial including more than 2500 British teenagers.

I have led multiple research studies in the UK and have worked with over 250 Latino and non-Latino families across the San Diego area to improve their diet, increase physical activity and lose weight.

As a leading scientist studying young people's health behaviours I gave keynote presentations, invited lectures and seminars and acted as chair at scientific conferences around the world.

Please note that in my academic work I use my maiden name Dr Kirsten Corder.


My story

When I was about 5 years old, my Mum took me to the doctor for a routine visit. It was a hot Summer day and the doctor was sitting at a desk in front of his large window. As we were walking out, my Mum took my hand and put her other hand on the door handle. As she turned to say goodbye to the doctor, he said five words that changed my life: “just watch her weight ok”. I looked up at Mum and felt a lead weight pulling at my chest. She did not say anything, but I knew that something was wrong. They spoke for a couple more minutes, but I do not remember what they said. I just remember feeling ashamed and wondering what I had done wrong.


From that moment on, my relationship with food was broken. I was always hungry and was now labelled as ‘fat’. Although I lost weight briefly, I gained it back with more. This continued so that I was overweight most of my school life and was teased because of my weight. Miss Piggy was my nickname throughout middle school, I never got picked for sports and couldn't wear the clothes that my friends did as they didn't make them in my size.


Being overweight as a child ruled my life but I knew that it did not need to be this way. That is why I spent my life researching to solve weight issues without stigma and restriction. Now I teach adults, parents and families how to lose weight, so they don't have to feel like I did.

It is more than 30 years after that doctor’s appointment, and I have finally healed my relationship with my body. It took 17 years of academic research, having kids of my own and a lot of self-reflection to find the answers.

My mission is that...

No one ever feels 'fat'.

No one ever feels guilty or judged about their weight.

No one ever feels stuck about how to lose weight.


I have learnt how to find and reverse the hidden causes of weight gain.

Let me teach you how to how to lose weight for good.
