The Claim
In middle-aged and older adults, the optimal combination of sleep (7.2–8.0 hours/day), moderate to vigorous physical activity (42–103 minutes/day), and diet quality (DQS 57.5–72.5) is associated with a 64% lower risk of all-cause mortality compared to individuals with the lowest levels of all three behaviors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who sleep just the right amount, exercise moderately to vigorously, and eat well are 64% less likely to die from any cause compared to those who don’t do any of those things well — especially if they’re middle-aged or older.
