M.Sc. In Dietetics after B.A. (English Hons), is there any way? Maybe after doing some Diploma?

Hi. I have completed my graduation this year with BA (English Hons) . I am inclined towards Dietetics and health and would really like to pursue MSc in Dietetics or clinical nutrition. But as I checked the eligibility and looks like I am not eligible . Is there any way,maybe doing a diploma first ?
