His contributions to medical science include simplifying low blood glucose testing, introducing insulin radioimmunoassay, and advancing diabetes research.

Marks was also a nutritionist who studied intestinal hormones and coined the term "muesli belt malnutrition", referring to parents feeding their children what is considered extremely healthy foods, but, in the process depriving them of essential fats.
