Diet And Nutrition Coach Certification: Beginner To Advanced (Udemy.com)

Become A Nutrition Coach: Create Muscle Growth & Fat Loss Meal Plans, Build A Fitness Diet Business & Be A Health Expert

Created by: Felix Harder

Last updated December 2025

Our take

Based on the ratings of 10,282 students, a sample of their written reviews and the syllabus, as the course stood in December 2025. No course pays to be reviewed.

Felix Harder's nutrition coaching course is a short, plain-spoken introduction to how diets actually work: calories, macros, digestion, weight loss plateaus, muscle-building meals, popular diets and supplements. It runs about 4.8 hours across 105 lectures, most of them a few minutes long, and finishes with a CPD certificate. The title says beginner to advanced, but the syllabus shows a beginner course. It suits personal trainers who want to talk about food with clients, and anyone who wants to understand their own diet without wading through textbooks.

Reviewers like the pace and the plain explanations. One says the comparisons to a car make a lot of sense, a new gym-goer found the material highly relevant to what his personal trainer had told him, and a physical therapist called it very helpful. The rating sits at 4.7 from more than 10,000 reviews, and the course was refreshed in December 2025. Complaints are mild. One reviewer wanted more diagrams inside the lectures instead of in the separate downloads, and a two-star review simply says the teaching could be better. There is only one quiz, so you check your own understanding.

The weak spot is the business side. The headline promises help building a fitness diet business, but the syllabus gives it a 12 minute bonus section on the coach and client relationship. Treat this as nutrition theory with a certificate, not a business course. Pick it when meal planning and diet theory are the goal rather than training or hormones, which other health and fitness courses we list beside it cover. For a first pass at nutrition coaching, it is an easy recommendation.

Best forPersonal trainers and gym regulars who want the nutrition basics explained plainly, plus a certificate to show for it.
Skip it ifYou want to learn how to run a coaching business; that part is a 12 minute bonus section at the end.

Pros

  • Short lectures at a steady pace; one reviewer says the comparisons to a car make a lot of sense
  • Covers weight loss, muscle gain, popular diets, supplements and vitamins in under five hours
  • Refreshed in December 2025, with 10 articles plus downloadable worksheets and eBooks
  • 4.7 rating from more than 10,000 reviews, with almost 90 percent at four or five stars

Cons

  • Business-building gets only a 12 minute bonus section, despite the headline
  • Only one quiz across 105 lectures, so there is little to test yourself on
  • Diagrams live in separate downloads; one reviewer wanted them inside the lectures
Great course, easy to understand, and very useful for learning the basics of diet, calories, macros, and healthy eating.

Listed as all levels, but it is a beginner course; the only stated requirements are a passion for nutrition and a willingness to help others.

So far, so good! I recently started working with free weights in the gym and I've booked a few PT sessions who was talking about some of these principles in the consultation. So highly relevant material here.

By Jeanne Mileine Beauvais on 7/14/2026

"This course has been incredibly informative and engaging, providing a solid foundation in diet and nutrition that is perfect for beginners and advanced learners alike.

By Geeta Durgani on 5/5/2026

Getting more interesting as I keep learning more & more but sometimes the verbal instructions are not too clear. Some words can't be understood unless I re-watch.

By Shamim Bano on 4/4/2026

Why I take this course, because I am a diabitic Patient and I want to learn each and everything about my diet and fitness to cure myself as well as I want to become a Nutrition coach to give benefit others.

By Kelly Bujnowski Paura on 3/30/2026

Acredito que poderia incluir uma lista em pdf mais organizada e mais rica dos alimentos, tanto para ganho de massa quanto para perda de pessoa e a quantidade que a pessoa deveria comer. Por exemplo, por dia, para eu ganhar massa é recomendado que eu coma no maximo 48g de açucar por dia, não incluindo frutas nessa contagem. Alem disso, poderia ter um mini video explicando a importancia de ter uma balança, para não quebrar a dieta de maneira "invisivel", como comendo nozes demais (fat).

By Lawrence Carlos on 2/14/2026

It is a really good course, since I am freelance coach, it helps me a lot on the things that I needed to know about diet and food that my clients need.

By Melinda Adams on 1/27/2026

I have taken some health and wellness classes and got to know a lot of new stuff.... but have so much very detailed stuff about food and how it affects you (good & bad) this course that blow my mind. It is great so far and want to learn more
