What aspect of health are you interested in. Menopause, acne, diabetes 2, IBS, ADD, autism?
Have you the drive to start your own business, pay overheads, insure yourself, do your own marketing and sales and manage your clinic, pay for membership of professional associations if you qualify with that certificate to be accepted, and comply with regulations like GDPR about your clients?
Have you thought about the actual need for dietitian services in your area? Are there any others? Is the market saturated?
From what I know from friends who trained (three year degree and then yearly professional development) about being a private dietitian, it’s a very tough gig and a slow grind before you actually break even.
There’s a lot of non compliant patients who just don’t do what they’re told.... it’s a very frustrating job actually.
Another person saying stick to your job, and use your down time to volunteer in a hospice or care home feeding elderly patients, or take them for walks in their wheel chairs.
I did this for a summer and it was very rewarding.
