About DYF Nutrition
DYF Nutrition helps endurance athletes better understand and prepare their fueling: carbohydrates, hydration, sodium, and homemade recipes.
Why DYF exists
Endurance nutrition advice is often scattered. Between gels, sports drinks, scientific recommendations, real-world tips, and digestive constraints, it’s easy to get lost.
DYF exists to turn these useful benchmarks into practical tools: a calculator, guides, articles, and concrete examples. The goal isn’t to deliver «the perfect strategy», but a clear starting point to test gradually in training.
Who is behind DYF
DYF is an independent project whose public editorial responsibility is carried by Lucas Berenguer.
We created DYF after a simple observation: many athletes want to manage their fueling better but face scattered advice, an overwhelming product offer, and recommendations that are sometimes hard to apply in practice.
The aim is to make nutritional benchmarks more accessible without oversimplifying them. DYF is neither a supplement brand nor a closed method: it’s a tool to help understand, prepare, and adjust your strategy.
Editorial responsibility
Lucas Berenguer
Author and editor of DYF Nutrition
Lucas structures the articles, guides, calculator explanations, and source links. His role is editorial: make the information understandable, keep units consistent, and clearly separate practical benchmarks from medical advice.
No medical or dietetic qualification is claimed on this site. When professional clinical advice is needed, DYF explicitly directs readers to a qualified healthcare professional.
What DYF helps you do
- Estimate a target carbohydrate intake per hour suited to your effort.
- Adapt hydration to duration, intensity, and heat.
- Understand the role of sodium and electrolytes.
- Prepare a homemade drink or gel from simple ingredients.
- Translate theoretical guidelines into concrete quantities (grams, millilitres, milligrams).
- Prepare for long sessions: running, trail, cycling, hiking, triathlon.
The DYF editorial method
Every substantial page follows the same four-step review:
- identify primary or authoritative sources and keep the references visible;
- check units, conversions, numerical ranges, and consistency with the calculator;
- translate the evidence into a cautious plan that must be tested progressively in training;
- review links, wording, and update dates whenever the page changes materially.
The review is editorial, not clinical. A correction can be reported through the contact page and is incorporated when it is documented and relevant.
What DYF does not do
DYF does not replace a doctor, a sports dietitian, or any healthcare professional.
The content is not suited for medical conditions, treatments, kidney disease, hypertension, significant digestive disorders, eating disorders, pregnancy, or any particular medical situation.
If in doubt, seek professional advice.
Independence and affiliate links
Some product links may be affiliate links. DYF may earn a commission if a purchase is made through these links, at no additional cost to the user.
Products are presented as practical options, not as a purchase obligation. The main goal remains to help each person understand their needs before buying anything.
Who DYF is useful for
DYF is built for endurance athletes, beginners and more experienced alike:
- cyclists;
- runners;
- trail runners;
- triathletes;
- long-distance hikers;
- athletes preparing long sessions or endurance events.
Every nutrition strategy should be tested progressively in training — never on the day of an important race.
