The improvement in LDL kinetics (increased catabolism) following weight loss is inversely correlated with reductions in plasma Retinol-Binding Protein-4 (RBP-4).
Lowering your body fat reduces a protein called RBP-4. This reduction helps your body clear 'bad' LDL cholesterol more efficiently, which is a key benefit of weight loss for heart health.
GoodSupportsHIGH confidence
The increase in LDL catabolism was inversely correlated with the fall in RBP-4 (r = -0.54, P < 0.05)
Why this rating
Strong statistical correlation within a controlled trial, but observational in nature regarding the biomarker link.

- In obese men with metabolic syndrome, short-term weight loss via a hypocaloric low-fat diet increases LDL apoB-100 catabolism, thereby lowering plasma LDL cholesterol concentrations.Good
- In obese men with metabolic syndrome, weight loss decreases HDL apoA-I production and catabolism by equal amounts, resulting in no net change in plasma HDL cholesterol concentrations.Good
