Level 5 - mechanism / opinion, no new human data
Narrative review evaluating theoretical models and selected feeding trials

What was done
This narrative review evaluated the carbohydrate-insulin model of obesity against the findings of two recently conducted, carefully controlled inpatient feeding studies that tested key model predictions regarding carbohydrate intake, insulin secretion, energy partitioning, hunger, and metabolic rate.
What was found
The abstract reports no quantitative values or statistical metrics. It reports that results from a pair of carefully controlled inpatient feeding studies failed to support key predictions of the carbohydrate-insulin model, experimentally falsifying important aspects of the model and indicating that it is too simplistic.
Why it matters
This review synthesizes experimental challenges to the hypothesis that carbohydrate-driven insulin secretion is the primary driver of obesity and metabolic suppression, indicating that obesity mechanisms cannot be explained solely by this framework.
Limits
This is a narrative review rather than a systematic review. The abstract discusses only two feeding studies, gives no quantitative data, and provides no details on sample size, participant characteristics, study durations, or long-term clinical outcomes.
