This presentation is based on the clinical scholarly project she implemented in the DNP program.


Background: Adult obesity has been an epidemic issue and a significant public health concern today.  Despite the effort to reduce obesity in the past several decades, obesity rates have continued to increase.  There is an urgent need for an effective and sustainable strategy for weight loss to reverse this epidemic. 
Objective: The purpose of this project was to promote low-carbohydrate, high-fat (LCHF) diet for weight loss. 
Methods: Total of 25 participants whose BMI was 25 or above were recruited in this project at an internal medicine clinic in Tempe, AZ.  Participants were asked to follow seven Japanese eating habits that would naturally put them on the LCHF diet for two months.  Their weighs at baseline, one month, and two months later were obtained, and weight changes were analyzed.  Eating behavior questionnaires were also used to measure the outcomes of eating behavior changes eight different appetitive traits.
Results: Paired-sample t-test was used to analyze the weight changes.  The average weight change was -1.1 lb. (SD = 1.3, p = 0.000) after one month, and -4.1 lb. (SD = 2.7, p = 0.000).  Wilcoxon signed-ranks test was used to analyze the eating behavior changes.  No eating behavior changes were indicated in all appetitive traits at a 95% confidence level of significance.  On the evaluation survey at the end of the project, most participants strongly agreed or agreed that the LCHF diet was easy to follow (92.0%); and most participants also strongly agreed or agreed that they could continue to follow the LCHF diet for more than a year (92.0%).
Conclusion: The results of this project indicated that LCHF diet utilizing Japanese eating habits was effective in weight loss.  The eating behaviour change questionnaire used in this project did not show any changes.  However, participants’ evaluation indicates that the long-term sustainability of this diet may be expected.
