Adhering to five low-risk lifestyle factors (never smoking, moderate alcohol, high diet quality, normal BMI, and regular physical activity) significantly increases life expectancy compared to having zero such factors.
To maximize your life expectancy, aim to adopt five specific habits: never smoke, maintain a BMI between 18.5 and 24.9, eat a diet high in vegetables, fruits, nuts, whole grains, and healthy fats (upper 40% of AHEI), limit alcohol to 5-15g/day (women) or 5-30g/day (men), and exercise for at least 3.5 hours per week at a moderate-to-vigorous intensity. Doing all five can add up to 14 years to your life compared to having none.
We estimated gained life-expectancy as differences in expectation of life at any given age between any two lifetables compared.
Why this rating
Large prospective cohorts (NHS/HPFS) with robust statistical modeling, though observational.
