Fluctuating caloric intake has measurable adverse health effects
the verdict
SUPPORTED
the evidence backs this
confidence 59/100
The weight of recent evidence indicates that fluctuating caloric intake and weight cycling have measurable adverse health effects, including disrupted glucose homeostasis, chronic inflammation, and musculoskeletal risks, despite occasional conflicting animal findings.
