Intervention
Calorie restriction with adequate nutrition
Research Observatory
Evidence Update
Current evidence
Moderate achieved calorie restriction in CALERIE improved several risk factors but reduced bone mineral density at important skeletal sites.
What changed
Adds a population-specific balance of metabolic signals and bone tradeoffs.
What did not change
No general longevity prescription, cardiovascular-event reduction or fracture-harm estimate follows.
Why it matters
An intervention profile should show both desired and undesired measured effects.
Main limitation
One selected trial, approximately 12% achieved restriction, surrogate outcomes.
Next proof
Durable clinical benefit and safety, including feasible mitigation.
Summary
Moderate achieved calorie restriction in CALERIE improved several risk factors but reduced BMD at important skeletal sites.
Intelligence Take
An intervention profile should show both desired and undesired measured effects.
Limitations
One selected trial, approximately 12% achieved restriction, surrogate outcomes.
