About me
Hi, I’m Sarah
I’m a registered (sports) dietitian based in Rotterdam & online, with 8+ years of experience. I specialise in strength and weight-class sports — think MMA, BJJ, kickboxing and judo — but work with everyone from recreational athletes to people managing conditions like diabetes or high cholesterol.
As a business owner, athlete, and coach, I understand the physical and mental demands of training hard, performing under pressure, and staying healthy. Having also lost 8 kilos myself and competing at the highest level, I’ve learned firsthand how nutrition can make or break your performance — in life and in sports.

Choose between nutrition advice, a 3–6 month coaching programme or hire me for nutrition support at gyms, sports organisations or schools.
Explore my services and let’s create a plan that truly fits you.
No standard plan but personal advice that truly fits you. Choose from:
General nutrition advice: Eat healthier, lose weight, manage your energy or improve a health condition. Includes personalised nutrition advice and an optional meal plan.

Ideal for getting started independently. Plan 2–3 follow-ups for optimal results. Upgrade to a coaching programme is possible.

Ik werk nu sinds 4 maanden met Sarah en ben al 10kg kwijt sinds dat we zijn begonnen. Sarah legt alles duidelijk uit en geeft echt hele goede adviezen die niet alleen helpen met gewichtsverlies maar ook met gezondheid waardoor ik bewuster ben van wat ik eet of drink. Ook zorgt ze ervoor dat de adviezen die ze geeft ook aansluiten op je sportieve doelen en houd rekening met gezinsleven en past advies ook hierop aan. Thanks Sarah!

I loved Sarah! She listens well, is honest, professional and friendly. I needed that personal approach and customized advice, especially after years of yo-yo effect, starvation and a damaged body image. There are many dietitians, but you rarely find someone who is really passionate about it and doesn’t send you home with a boring plan that puts you back to the same point. Perfect!

If it hadn’t been for Sarah, I wouldn’t have been the athlete that I am. She has helped me countless of times to cut weight in a healthy, responsible and science proven way and also provides a day to day nutrition plan for when I’m not competing. Sarah is incredibly precise in the way she works, very structured and makes me a part of the process as much as she is. I have recommended her to many others who all have had as much positive experiences as me, and I will continue to recommend her!

I train BJJ intensively and struggled to keep my weight and my energy stable during training and competitions. Thanks to Tuohy Nutrition, I now have a nutrition plan that helps me stay consistently well-fueled without experiencing energy spikes followed by crashes. What I appreciate the most is that the diet is not extreme or overly restrictive. I highly recommend this to any BJJ practitioner looking to optimize their nutrition!

Highly recommending working with Sarah! She helped me throughout my weightloss journey when I had been spinning my wheels, and lost 13kg in the smoothest way possible over the course of a few months. I also now know how to fuel my trainings properly (for BJJ, Gym and wrestling), and am always shocked by how much of a difference it makes. Sarah is super kind and always adapts to the feedback you share while working with her!

Sarah is the best nutritionist I’ve had the pleasure of working with. She had no problem being able to help me with losing weight and working around my challenges with T1 Diabetes and my endocrinology team. She’s been able to help me dial in my nutrition for BJJ and endurance sports while also guiding me through a steady process to help me get to my best self. Highest level available in Rotterdam. She’s excellent.
