Observational Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07613255). This is a study registration, not published results. Lead sponsor: Pennington Biomedical Research Center. Recruitment status: NOT_YET_RECRUITING. Study type: OBSERVATIONAL. Enrollment: 10 participants (ESTIMATED). Conditions: BMI>40. Interventions: OTHER: High-fat test meal. Primary outcome measures: 24-hour Energy Expenditure , Day 9; 24-hour Fat Oxidation , Day 9; Basal Energy Expenditure , Day 9; Resting Energy Expenditure , Day 9; Sleeping Metabolic Rate , Day 9; Thermic Effect of Food , Day 9; Spontaneous Physical Activity , Day 9; Free-living Total Daily Energy Expenditure , Day 1 to Day 8. Brief summary: This research will evaluate energy metabolism (expenditure and fat oxidation), metabolic flexibility (response to a high-fat test meal) in 10 individuals with a BMI ≥60 kgm2 using gold-standard assessments of energy metabolism, metabolic flexibility, and body composition. Males and females (18-80 y) with extreme obesity (BMI: ≥60 kg/m2) will be recruited from Baton Rouge, Louisiana. Exclusion criteria include major organ failure, uncontrolled endocrine disease, severe psychiatric illness, pregnancy, and inability to comply with study procedures. The total duration of participation for each individual is estimated at approximately 10 days. If qualified, participants (BMI≥60 kg/m2; n=10) will complete one outpatient visit and one inpatient visit with 36hr metabolic chamber testing.
