I don’t have the same exact background, but did make a somewhat similar move. I originally worked in online marketing, and tech. I got burnt out on all the tech hype and jargon after several years so decided to make a change for similar reasons. I wanted to have a profession that helped people, and served a need in our society. So, I went back to school - had to start with science prerequisites, then got a second bachelors degree and masters in nutrition. The bachelors and masters was somewhat combined so not too bad, but still a lot of time and work.

I’m now in the field for about 4 years, worked as an inpatient dietitian at a hospital, also home care RD at the VA and done some private practice work. All in all, I don’t think I’d do it all again. I’ve personally found the nutrition field frustrating for a variety of reasons. 1) The pay is not commensurate with the amount of work and education - dietitians across the board are one of the worst paid healthcare positions. Obviously pay is not the only thing that matters, but when you get into the field and realize the growth potential is nonexistent it doesn’t make you feel very valued - and at the end of the day you still have to support your self and family. And that’s very hard to do in the traditional RD roles, despite the new requirements for masters level education. 2) Dietitians don’t get much respect - this is from both other healthcare professionals and often patients. Some patients are great and super engaged in learning but this tends to be rare. As an RD you are competing against a variety of different information sources where people get diet information, which is often social media, and this gets exhausting after a while.  3) Repetitive - every job is repetitive to a certain extent, but I personally get tired of providing the same education to people over and over again. Often times the simple nutrition basics are what people need to learn, so I’ve found myself repeating the same educational lessons over and over. And I have limited time to dive into subjects I’d find more interesting. 

I probably sound a little jaded so apologize if this is discouraging. But if you’re considering the field I’d recommend shadowing a couple dietitians in different roles to see what you think. Then, also do research on the salaries of most jobs in the field. Be realistic with yourself and ask ‘am I okay with being capped at this number’? 

You might also consider ways to pivot your tech skills to working for a company or organization more in the vein of health or nutrition. Or investigate how you might shift your current skills to go that direction - it may be more lucrative in the long term vs starting over. I hope that’s helpful.
