This study included 1048 participants between the age of 50 and 80 years old without cardiovascular disease (Hu T, et. al., 2023).
The researchers investigated the associations of 2-year changes in fat percentage and fat-free mass percentage with occurring cardiovascular events.
This is what they found. The participants with a fat% gain of 2% or more had an increased risk of cardiovascular events when compared with participants with a stable fat%.
They also found that fat-free mass percentage loss of 2% was associated with an increased risk of cardiovascular events.
