About

Hi, I’m Dr Jules Strauss

A registered nutritionist specialising in endurance performance and supporting female athletes at every phase of life — bringing the science out of the lab and onto the start line.

My story

A woman with blonde hair sitting on a wooden table, holding a white mug, smiling at the camera, with a laptop on the table and a window with shutters in the background.

After my PhD, I moved to Liverpool John Moores University, where I began my career as a lecturer. Health remained an important part of my work, but I was fortunate to be able to broaden my research into understanding how the body responds and adapts to training and nutrition under real performance demands. In more recent years, my research has shifted further toward female athletes, particularly how hormonal shifts influence nutrition recommendations and behaviours.

I've always been sporty, which led me to a Sport and Exercise Science degree at the University of Birmingham, a Master’s in Sport and Exercise Nutrition at Loughborough University, and a PhD researching exercise metabolism and specifically the mechanisms underpinning type 2 diabetes, work that showed me how powerful good science can be in shaping interventions that genuinely improve people's lives.

Around the same time, I became a Registered Nutritionist and, in 2020, co-founded what's now FuelHQ. My own relationship with endurance sport deepened too, from sprint triathlon up to half Ironman, and in 2024 I finally ran the London Marathon, a real bucket list moment.

Working with athletes professionally and training as one myself, I noticed so many were making the same mistakes, struggling with low energy, recurring injuries, and constant tiredness, most without access to proper nutrition support. That gap became the reason FuelHQ exists, providing accessible and quality evidence-based nutrition support for endurance athletes of all levels.

Over my time in academia, I published more than 60 peer-reviewed papers and became an Associate Professor; and FuelHQ has now supported over 400 endurance athletes. I've also had the privilege of providing nutrition support for the Comic Relief Celebrity Challenges, including Billy Monger's "The Race Is On", Jamie Laing’s Ultra Marathon Man and Greg James' "The Longest Ride”. I’ve been so lucky to do all of these things, and the breadth of experience that it brings to the way I can support my clients.

My approach

Evidence First

Every recommendation is grounded in current research, not trends or guesswork. As an active researcher and practitioner, I pride myself on making the science simple, accessible, and actionable.

Individualised, Not Generic

No two athletes are the same and neither are their nutrition needs. Support is built around what's actually happening for each person, not a one-size-fits-all plan.

Built for Real Life

Good nutrition advice must work alongside a busy job, a training schedule, and everyday life. I focus on strategies that are realistic to sustain, not just optimal on paper.

Who I work with

  1. Professional teams and athletes looking for high-quality, experienced, evidence-based support

  2. Endurance athletes — runners, cyclists, triathletes and beyond

  3. Female athletes at every phase of life

  4. Recreational athletes wanting to train and race better

  5. Brands, teams and media seeking expert input
