The aim of this study is to compare the effects of two different protein supplements
(partially hydrolyzed whey protein, PHWP vs. partially hydrolyzed gelatin, PHG) on weight
loss in obse individuals with metabolic syndrome (METS). These two supplements will contain
equal amounts of protein but differ considerably in their amino acid contents. Whey protein
is rich in essential amino acids whereas gelatin is rich in proline.
In obese individuals with METS, the hypotheses are:
- PHWP will augment fat-mass loss and increase lean-mass to fat-mass ration more than
PHG.
- PHWP will improve insulin action more than PHG.
- PHWP will decrease cardiovascular disease risk more than PHG.
The Metabolic Syndrome (METS) is a clinical disorder characterized by the following
problems: Obesity, especially located in the waist area, elevated blood fats (lipids), high
blood pressure and insulin resistance. The METS affects one third of the adult population in
the USA and increases the risks for both diabetes and hardening of the arteries, leading to
heart attacks and strokes.
The best treatment for improving the symptoms of METS is weight loss. In previous studies,
it has been demonstrated that whey protein (WP) supplementation increased weight loss and
especially fat-mass loss in obese, insulin resistant women when compared to carbohydrates.
We now propose to compare WP to another protein source in patients with the METS during
weight loss. In addition, we will use a special preparation called partially hydrolyzed whey
protein, which may have specific properties that increase fat mass loss.
