Early eating windows had mixed effects across clinical subgroups
An exploratory trial analysis found improvements in some blood pressure and blood sugar measures, but cholesterol increased among adults with severe obesity.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Early eating produced mixed results across clinical subgroups. Diastolic blood pressure, the lower reading, decreased in adults with hypertension, and a blood sugar marker improved in those with prediabetes. Cholesterol rose in adults with severe obesity. These exploratory findings concern adults receiving weight-loss treatment and do not establish a benefit for everyone.
The abstract does not define the uncertainty measures accompanying these estimates. This was an exploratory subgroup analysis, and the small Black participant sample limits interpretation of apparent racial differences.
What researchers found
Cholesterol increases in adults with severe obesity
Early eating window versus control over 14 weeks; positive values indicate higher cholesterol with early eating.
Different markers, different subgroups
In participants with high cholesterol, early eating improved an index of insulin resistance. These biomarker changes do not establish fewer cardiovascular events, and results from a clinical subgroup should not be assumed to apply to everyone.
Demographic findings remain tentative
The analysis detected no differences by age or sex. Blood pressure and blood sugar outcomes appeared to improve more in Black than White participants, but the authors cautioned that the Black participant sample was small.
