I started late in the nutrition game and ended up becoming a nutritional consultant because I couldn't dedicate the time to becoming a dietician. I think it is amazing that you are on this path! Congrats! I would recommend exploring all of the different fields in nutrition. Most people don't look into plant based nutrition, which is actually a very important part of this industry and can give clients results that other doctors cannot achieve. I have worked with clients who are now cured from heart disease, fatty liver, and leaky gut from taking a plant based approach.
If you can intern with not only dietitians, but also health coaches I think you will get a very good understanding of what is really going on in this industry.
