    My contribution to this paper

    This paper was the result of a research protocol drawn up by the senior authors for submission for funding to South African research funding organisations. I was originally invited by the authors to contribute inputs to the planned protocol, the goal of which was to raise the funds to support the research. I was invited to contribute because I am a leading South African authority on the metabolic and health effects of a low carbohydrate diet and I assume the authors believed I could make a contribution that would enhance the probability that the study would be of sufficient value to receive funding. As I recall the original proposal was to have focused principally on the role of carbohydrate ingestion as a risk factor for cancer - a topic about which there are few meta-analyses. Subsequently the focus of the protocol and the review changed somewhat. I reviewed the original research protocol and made specific inputs. I reviewed and commented on the final manuscript that included those comments. That is how I remember the origins of this paper.

    Conflict of Interest:
    I am an advocate of the low carbohydrate diet for the management of clinical conditions linked to hyperinsulinaemia/insulin resistance. I have written three books that deal specifically with the low carbohydrate diet - The Real Meal Revolution; Raising Superheroes (Superfoods for Super Kids); and Lore of Nutrition. The latter book reviews the scientific evidence for my stance and the professional consequences to me that that my "unconventional" position on nutrition has led to over the past 7 years including a 4 year professional hearing for alleged "unprofessional misconduct".
