Macro partitioning
Orlistat treatment improves obesity-related cardiovascular and metabolic risk factors, including lowering LDL cholesterol, total cholesterol, and fasting insulin levels, independent of the magnitude of weight loss.
Orlistat not only helps you lose weight but also independently improves your cholesterol levels (LDL and total) and insulin sensitivity. This benefit persists even when accounting for the amount of weight lost, suggesting a direct pharmacologic effect on lipid metabolism due to reduced fat absorption.

Treatment with orlistat, 120 mg 3 times a day, was associated with improvements in fasting low-density lipoprotein cholesterol and insulin levels.
Why this rating
Large-scale RCT with rigorous statistical analysis (ANCOVA) controlling for weight loss.
