The science

It’s an oft-quoted statistic that 95% of generic diet and training plans fail. Yet research also shows that personalised plans tailored to the individual buck this trend*. At FitnessGenes, we utilize the most unique thing about you to create truly personalised plans – your DNA.

Our team is composed of PhD scientists and experts in genetics, sports science, biology, and biochemistry. With the team’s combined skillset, our understanding goes beyond genetics, extending to the physiology of how to develop a training protocol and nutritional advantage. Our scientists also engage in prominent academic collaborations to test and further refine our model as well as to ensure our recommendations are scientifically sound. Meet them on our bio page.

Our process

Our process explained

You are unique, mainly as a result of your DNA. The first step in the FitnessGenes process is uncovering the genetic variations that you carry that have been linked to physical performance and nutrition. A simple saliva test is all that’s required to analyse these 43 different genetic variations in your DNA.

We all have a goal in mind when we start our fitness journey. Rather than tell you what type of athlete you should be, our aim is to support your personal fitness ambitions. Fundamentally you determine what your goal will be, and we design our recommendations to help you achieve this.

We understand that an individual’s environment is equally as important as their genetic profile in understanding the way their body’s physiological systems function. A man may have all of the hallmark genetic variations associated with high testosterone levels, but if he is obese he is more likely to have a testosterone level which is lower than average. That’s why we ask you to complete a lifestyle survey when you sign up, so we can account for both genes and lifestyle when we make our recommendations.

Every day, our team of in-house researchers evaluate peer-reviewed academic literature from across multiple fields to further understand the role genetics plays, and how it can influence your training and nutrition. Hundreds of papers are reviewed each month, ensuring that FitnessGenes is the source for the most comprehensive and up-to-date information on fitness genetics possible.

As well as our dedicated team of in-house researchers, we also work with experienced academics from leading UK universities who help us to further refine our own knowledge and understanding.

Your genetic information, environmental data and individual fitness goals are all combined within our proprietary in-house model to provide you with relevant actionable advice.

These PERSONALIZED RECOMMENDATIONS allow you to achieve your goals more efficiently by training and eating smarter!

Academic collaboration

Innovate UK

FitnessGenes is a 2015 Winner of an Innovate UK government smart grant to advance science, engineering and technology.

Loughborough University

Working in collaboration with Dr David Stensel and James Dorling, researchers at the School of Sport, Exercise and Health Sciences at Loughborough University, FitnessGenes is studying the interaction between genetics and eating behaviour to better understand how certain genes may be linked to body weight.

University of Birmingham

With expert guidance from Professor Jean-Baptiste Cazier, head of the Centre for Computational Biology at the University of Birmingham, and his team, FitnessGenes will be reviewing and challenging the assumptions on which our recommendations are based using bioinformatic analysis of our own data sets to provide more accurate and science-based outcomes.

It is our belief that part of the problem with the genetic testing industry has been the lack of actionable information provided to customers. By working with academic groups to help further the research, constantly challenging the assumptions on which our recommendations are based, and also, importantly, overlaying relevant environmental information such as eating behaviour, weight and activity levels, we will start to more fully realise the benefits a personalised fitness training and nutrition plan can bring to us all”.
