Adhering to current physical activity guidelines and expending approximately 4200 kJ (1000 kcal) of energy per week significantly reduces all-cause mortality in women, with a magnitude of benefit similar to that observed in men.
To reduce your risk of death, aim to burn about 1000 calories (4200 kJ) through movement each week. This can be achieved through a mix of leisure exercise, walking, and household activities. You do not need to be a professional athlete; consistent, moderate activity is sufficient to gain a mortality benefit comparable to men.
It was concluded that, by adhering to current guidelines for physical activity and expending about 4200 kJ of energy a week, women can postpone mortality. The magnitude of benefit experienced by women is similar to that seen in men.
