Objective: The purpose of this cross-sectional study was to survey the knowledge and perception of very low carbohydrate ketogenic diets (VLCKD), particularly for conditions other than epilepsy, among nutrition professionals in the U.S.
Methods: A total of 804 nutrition professionals were surveyed between November and January of 2015-2016, utilizing email listservs from the Academy of Nutrition and Dietetics, as well as the following dietetic practice groups: Diabetes Care and Education, Dietitians in Integrative and Functional Medicine, Oncology Nutrition, Research, Vegetarian Nutrition, and Weight Management. A VLCKD-knowledge scoring system (KD-SCORE) was developed to evaluate respondents’ knowledge and perceptions of expected clinical outcomes in response to VLCKDs. In addition, the survey assessed general and professional demographics, as well as perceived therapeutic value for chronic conditions and level of concern for various nutrients and food groups on a VLCKD. Lastly, general and professional demographics significantly associated with KD-SCOREs were used to create a model to predict VLCKD-knowledgeable nutrition professionals.
Results: Frequency of request for VLCKD was low, with only 3% of the sample reporting “frequent” request. Mean KD-SCORE was a 17.11 out of 35. Respondents who reported most frequently being asked to plan VLCKDs in practice had the highest KD-SCOREs, and those with the highest KD-SCOREs were also significantly less likely to recommend discontinuation of the diet (Spearman’s rs = -0.619, p < 0.0001). Those most frequently requested to plan a VLCKD ascribed the most therapeutic value to CVD, hypertension, and athletic performance. For all condition except epilepsy, those with the highest KD-SCOREs attributed significantly more value of VLCKDs than lower scorers. There was a high degree of concern for all of the following food groups and nutrients of concern: CHO, total fat, protein, SFA, fruit, vegetables, whole grains, and fiber.
Conclusions: Knowledge of clinical effects of VLCKDs was determined to be variable by frequency of request. Degree of concern for intake of several major food groups and nutrients was variable by KD-SCORE. Furthermore, there do not appear to be many common demographic or professional characteristics associated with VLCKD-knowledge.
