Energy balance

High-intensity lifestyle interventions are associated with a modest, statistically non-significant reduction in all-cause mortality (OR 0.86), though the point estimate suggests a potential benefit.

While high-intensity lifestyle interventions may reduce mortality, the evidence is not yet statistically definitive due to low death rates in trials. However, the observed 14% reduction is promising and aligns with other long-term health data.

Why this rating

Meta-analysis of RCTs, but limited by low mortality rates and short follow-up in many studies.
