Our take

Based on the ratings of 1,666 students, a sample of their written reviews and the syllabus, as the course stood in March 2025. No course pays to be reviewed.

A free hour of nutrition basics from Felix Harder, a fitness coach who has been on Udemy for close to a decade. The 26 short lectures walk through calorie balance, protein, fat and carb targets, meal timing, food choices and a handful of supplements. The syllabus shows five sections, the longest under 25 minutes. It's for people who have never tracked a calorie and want the big picture before they start. Anyone who has read a couple of evidence-based nutrition articles will find little that is new, and reviewers say so.

Students like how clear and orderly it is. Several call it perfect for beginners, praise the plain speech and clean slides, and one singles out the section on macro quality as especially informative. The 4.5 rating from about 1,700 reviews, with 85 percent at four or five stars, backs that up. The complaints are about depth. One reviewer wanted sample meal plans, another felt half the chapters were spent previewing the next chapter, and a three-star review points out that it ignores anyone with a health condition like diabetes. One two-star review also finds the presentation style dated and asks for graphics, though the course was refreshed in March 2025.

As a free course it costs nothing but an hour, which is the right price for what it is. Next to the certification courses it shares the page with, this is the quick primer, not the training. Take it if you want the basics explained once, calmly, then go and try them. Skip it if you're after a written plan or the science behind the numbers.

Best forComplete beginners who want the calories-and-macros basics explained plainly in an hour, for free.
Skip it ifYou already know your macros or need sample meal plans, deeper science, or advice for a medical condition.

Pros

  • Free, and only 65 minutes across 26 short lectures, so it fits in one sitting.
  • Reviewers praise the clear speech, clean slides and logical order of topics.
  • Covers calorie balance, protein, fat and carb targets, meal timing and food quality without fluff.
  • Refreshed in March 2025 and holds a 4.5 rating from about 1,700 reviews.

Cons

  • No sample meal plans or worked examples, which a couple of reviewers asked for.
  • Too basic if you've already read up on nutrition; one reviewer felt half the chapters just preview later ones.
  • Assumes a healthy adult and says nothing about conditions like diabetes.
Nicely structured and presented, concise, scratches on the surface of a more scientific approach while not going into depth in this respect.

Listed as all levels, but it really suits absolute beginners; no prior health knowledge is needed and none is assumed.

We will talk about the right calorie balance and the right macronutrient split - so how much protein, fat and carbs you actually need. I will also teach you about proper meal timing and a small number of supplements that are actually proven to work and not just marketing hype.

Quite high level and designed for people who have no health conditions e.g., diabetes etc., and no mention of people who do have existing health conditions, which billions do. Also many people don't use Fakebook, main reason being it's a Zionist application.

By Balkis Thasleema.R.K. on 8/11/2022

Useful information....it is appreciated if he includes some sample diet chart...so it will help us to make diet chart.....the way In which he ordered the topics are good for beginners to understand

By Sophie Püschel on 2/16/2022

Nicely structured and presented, concise, scratches on the surface of a more scientific approach while not going into depth in this respect. Only caveat: For anyone who has already done some research about fitness nutrition, there won't be that much new info, but it's still worth your time

By Onkar Arun Jalake on 3/23/2021

Great course for beginners. I definitely loved the hierarchy and levels of teaching. The course is full of QUALITY content. The instructor seems to have great knowledge of things he teaches. Also he is able to deliver it nicely. This course has met all my expectations (is even beyond). Thank you. P.S. clear speech and sufficiently audible sound with clear crisp presentations

By Fabiana Alves on 9/1/2020

I was so happy with myself at the end of the course, when I saw the 6 pack meal plan given at the end and realized that I was already doing the same diet (with exception of the last meal) for the past 2 days. I had been been on the same page as the previous course (Weight Loss) info given. Thank youu!

Muito bom! Era o que eu estava procurando, explicou clara e objetivamente as informações que eu precisava saber. Adorei saber que você fala português também, ia fazer o review em inglês, mas sou brasileira Muito obrigada pelo conteúdo

By Natanael Hans Effendy on 3/13/2019

The course really gave a helpful insight for beginners who are trying to have the fundamentals of meal planning and nutrition. Highly recommended for anyone who’s trying to lead a healthier life or someone who’s trying to reach their fitness goal.

By Ibtissam Amghar on 12/5/2018

As a very first Udemy experience I really fell in love with the high quality content. I am someone who's familiar with the topic but still grateful for the amount of informations you've shared in this course. it wast the first time I got to consume your content and I'm sure It won't be the last. Thank you Felix Harder! :)

By Kunal Arora on 6/30/2018

Felix did a great job with this one. I actually managed to plan my diet with the instructions given in the course. The building blocks are well explained with his guidance into forming them into an actual action course. To add to that, Felix is responsive and even provided a cheat sheet. Really it's like we wish for it and he has it. Thumbs up for the wonderful job!!

By Berkay Dinçman on 4/8/2018

It's good course for begginning. Direct short information about the basics. Quite informative. I Think whenever I forget something about nutrition i can come back and check this course for reminders. Theres one down side that measurement units are not metric. There should be both systems. Other than that I can recommend this course.
