About Endure

About James Ellis and Endure

My name is James Ellis, a Leeds-based health coach, registered clinical nutritionist, conditioning and fitness expert, and sports massage practitioner.

With a masters degree in nutrition science I can help with a wide range of food- and diet-related issues: supporting hormonal changes such as perimenopause, tackling weight loss, crushing cravings, battling infertility, fighting allergies and nutritional support for those with long-term illnesses. As the parent of two young girls, I’m also an expert in family nutrition and making sure the whole family has a healthy diet.

Some of my key areas of expertise include:

Support through perimenopause: Hormonal changes are a natural part of a woman’s life cycle – and as much as third of your life can be spent in the post-menopause, so making sure you are in optimum shape to face the future is super important.

Sports and endurance nutrition: As an endurance athlete, I have a keen interest in sports and endurance nutrition. If you’re an endurance athlete such as an ultramarathon runner or long-distance cyclist, good nutrition can help take your performance to new levels.

Allergies and intolerances:  Both myself and one of my daughters have suffered from food intolerances, so I know how troublesome they can be. I can offer a range of tests and nutritional interventions to pinpoint problem foods and help alleviate any unwanted symptoms.

Whatever you see me for, you can be sure I’ll take a holistic approach to our work together, looking at every aspect of your diet and lifestyle, and relying on the latest evidence-based science to support you in reaching your goals.

I also offer personal training and sports massage services. Please see the relevant sections of the site for more details.

About me

After a long career on the desks of national newspapers writing about travel, health and other feature stories, I got a shock in 2006 when I lost my father. The sad thing is, it was totally avoidable, but… he was overweight, didn’t exercise, drank too much, smoked and had a poor diet. What made things worse was that when I looked in the mirror, I could see I was following the same path.

I started going back to the gym, quit my cushy job to go freelance and re-trained as a personal trainer. A year later I started running, graduating onto ultramarathons and going on to represent Team GB four times at Spartathlon, the historic 153-mile race held in Greece every September.

Having seen the power of good nutrition as I followed this journey, I decided to expand my health and fitness knowledge by becoming a trained nutrition therapist. I am now reading for my MSc dissertation in sports nutrition.

Given my past,  I understand the barriers to eating well. Let me help you overcome your own barriers to achieve optimum health.

Nutrition, health & performance

For your body to achieve optimal performance – whether you are fighting a long-standing illness, suffer from everyday gripes or are training for a marathon – good nutrition is essential.

Nutrients and other food components determine how the body functions, how it can protect itself against disease,  or restore health in case of illness. In some cases, diet is a risk factor in a number of diseases, and science is increasingly showing that the balance between us being healthy or not may depend on our genetic profile and how that affects how we process food.

Some diet-regulated genes may play a role in the onset, incidence, progression, and/or severity of chronic diseases. Dietary intervention based on knowledge of nutritional requirements, nutritional status, and genotype can be used to help support the fight against chronic disease.

About Nutritional Science

Nutritional Therapy is the application of nutrition science in the promotion of health, peak performance and individual care. Registered Nutritional Scientists use a wide range of tools to assess and identify potential nutritional imbalances and understand how these may contribute to an individual’s symptoms and health concerns. This approach allows them to work with individuals to address nutritional balance and help support the body towards maintaining health.

Practitioners consider each individual to be unique and recommend personalised nutrition and lifestyle programmes rather than a ‘one size fits all’ approach. Practitioners never recommend nutritional therapy as a replacement for medical advice and always refer any client with ‘red flag’ signs or symptoms to their medical professional.
