Adherence
The cardiovascular benefits of dietary fat reduction are only evident in trials with a mean follow-up duration of two years or longer.
If you are changing your fat intake to protect your heart, expect to maintain these changes for at least two years before seeing the full protective benefit. Short-term changes may not reduce your risk of cardiovascular events.
GoodConditionalMEDIUM confidence
Trials in which the mean length of follow up exceeded two years showed somewhat larger reductions in combined cardiovascular events (0.76 (0.65 to 0.90) v 0.96 (0.75 to 1.23) than trials of less than two years’ duration.
Why this rating
Based on subgroup analysis of the same high-quality systematic review.
