Adherence
Increasing cardiorespiratory fitness (CRF) reduces morbidity and mortality regardless of changes in body weight or BMI, whereas intentional weight loss in healthy overweight/obese individuals does not improve and may increase mortality risk.
Stop focusing on weight loss as the primary health goal. Instead, aim for 150 minutes of moderate-intensity physical activity per week (like brisk walking or cycling). This level of activity significantly reduces your risk of death and heart disease, regardless of whether you lose weight. Prioritize feeling stronger and more energetic over the number on the scale.
More recent studies that do account for change in CRF show that an increase in CRF is directly associated with a reduction in morbidity and mortality regardless of changes in BMI, body weight, or body fat percentage... Intentional weight loss in healthy overweight and obese individuals has been associated with higher mortality compared to those who don’t intentionally lose weight.
Why this rating
The paper cites multiple meta-analyses and large cohort studies (e.g., Aerobics Center Longitudinal Study, Look AHEAD trial) supporting the fitness-mortality link.
