Macro partitioning
A low-fat diet intervention (targeting 20% of calories from fat) does not reduce the incidence of coronary heart disease, stroke, or type 2 diabetes compared to a control group with minimal dietary guidance.
Do not rely on a low-fat diet as a primary strategy for preventing heart disease or diabetes. Simply reducing fat to 20% without improving the quality of the remaining calories (e.g., replacing with refined carbs) does not improve outcomes.
GoodRefutesHIGH confidence
No difference in the rate of CHD, stroke, or CVD was found between the intervention group and the control group... there was no difference in incidence of self-reported T2DM between subjects in the low-fat intervention and control groups
Why this rating
Based on the Women's Health Initiative (WHI), a large RCT, though secondary outcomes and self-reported T2DM introduce some measurement noise.
