I’ve been fascinated between the link between what we eat and how we move and feel since studying dance full-time as an 18 year old. 

I went on to study for an MSc in Nutrition at the prestigious King’s College London and have worked as a nutritionist for over 15 years. 

No detoxes, no quick fixes, and no weight loss short cuts

My approach to nutrition, applies to wellbeing advice in general –   there is no ‘one size fits all’, and we must take into account all aspects of an individual – from preferences, lifestyle, genetics, age, culture and all of the other elements that make up someone’s wellbeing such as mental, financial and social health. A healthy diet is about so much more than individual nutrients, it’s about the way in which we eat – who with, how, and when. When we become obsessed with micronutrients and the individual components of diet, we reduce food to something much more simplistic than it is. 

I want to help people to find their own healthy relationship with food, and benefit from all that comes with this – be it more energy, a better mood, confidence, increased strength and fitness, and a better social life! 

My experience ranges from working as a consultant nutritionist and ambassador for brands such as Clipper Teas, Oskia skincare, Bespoke hotels, Foga shakes, working for the Children’s Food Trust as a lead on their ‘Let’s Get Cooking’ programme, working with running clubs, junior football teams, the England Walking Football Team and the Charlton Athletic Women’s Football team. 

I’ve also worked as a consultant and content advisor for health apps such as Noom, Nutrifix and Curb, as well as contributing as a nutrition and lifestyle expert for publications such as Top Sante, Women’s Running, Runner’s World, Women’s Fitness and Running Fitness Magazine, the Boots magazine, the Superdrug magazine and the Metro and the Evening Standard. 

I regularly feature as an expert nutritionist for the BBC, ITV and other leading media outlets. 

I also run workplace wellbeing nutrition sessions, working with clients such as Just Eat, Crossrail, HSBC and Amazon, to help employees to feel better physically and mentally, and be more productive and motivated in the workplace. 


"I came to your marathon nutrition workshop a couple of weeks ago and I’ve followed your advice. Today I ran a half-marathon with a personal best (shaved 5 minutes off my last year’s time). To say I’m delighted is an understatement! Nutrition wasn’t the only factor but I’m in no doubt that following your advice of drinking all the way round and fuelling properly before and during the race contributed to my success. Thank you!"

"Ruth’s session on nutrition for dealing with stress was an excellent way to start the new term. Aside from receiving practical and sensible advice, taking time out to consider our eating habits and making some resolutions to look after ourselves physically, we benefitted as a team, bonding over a nutritious breakfast together."
