Goal 2: Reduce Human Disease

Randomized trial of low carbohydrate high fat dietary pattern

There is a need for a large, simple, hard outcome trial of dietary advice to measure the effects of lowering simple carbohydrates versus lowering unhealthy fats. The main challenge will be to overcome bias favoring the more conventional dietary approach.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Critical Challenge (CC)

Details on the impact of addressing this CQ or CC

Substantial numbers are moving towards low carbohydrate/high fat diets to the extent that since 2000 the macronutrient composition of the US diet has changed towards lower carbohydrate and higher fat intakes; however, CV mortality rates continue to decline. The outcome of the trial will help frame future guidelines for healthy diets.

Feasibility and challenges of addressing this CQ or CC

Yes, since computer or smartphone based intervention materials and passive outcome collections (CMS, NDI, health care organizations) are increasingly being utilized.
Low carbohydrate high fat (LCHF) diets first popularized for weight reduction are increasingly being promoted to prevent diabetes and cardiovascular disease. All trials to date have been small and short term. Compared to more traditional high carbohydrate low fat diets, LCHF diets may be somewhat more beneficial for weight control, glucose homeostasis, and dyslipidemia, but less beneficial for LDL reduction.
