Whey Protein Reduces Appetite and Food Intake Compared to Other Proteins
A series of four studies conducted by researchers at the University of Toronto investigated the effects of different types of proteins on appetite and food consumption.
They found that whey protein and soy protein suppressed voluntary food consumption one hour later, while egg protein did not. Only whey protein consumed as either the intact protein or as peptides, suppressed food consumption a full two hours later. Soy protein did not.
AviClin Summary: StayFit Protein is a great way to control your appetite.
Whey Protein Reduces Weight Gain
This study investigated whether feeding insulin-resistant rats a high-protein diet (32%) containing whey protein concentrate would reduce body weight and tissue lipid levels and increase insulin sensitivity more than a diet containing red meat. Rats were fed a high-fat diet (300 g fat/kg diet) for nine weeks, then switched to a diet containing either 80 or 320 g protein/kg, provided by either whey protein or red meat, for 6 weeks. The rats were then killed after overnight food deprivation.
High dietary protein reduced energy intake and visceral, subcutaneous, and carcass fat. Increasing the dietary density of whey protein, but not of red meat, reduced body weight gain by four percent. Dietary whey protein also reduced plasma insulin concentration by 40 percent and increased insulin sensitivity, compared to red meat.
AviClin Summary: These findings support the conclusions that whey protein is more effective than red meat in reducing body weight gain and that increasing insulin sensitivity and a high-protein diet reduces energy intake and adiposity. StayFit Protein is a better choice than red meat to achieve a leaner body.
Whey Protein Consumed Before a Meal Increases Fullness and Controls Hunger
This study investigated the effects of two milk protein types, casein and whey, on food intake and subjective ratings of hunger and fullness, and on postprandial metabolite and gastrointestinal hormone responses. Two studies were undertaken.
The first study showed that all you can eat energy intake from a buffet meal was significantly less 90 minutes after a liquid preload containing 48g whey, compared with an equivalent casein preload.
In the second study, the same whey preload led to a 28 percent increase in postprandial plasma amino acid concentrations over three hours compared with casein. Blood levels of three satiety hormones-cholecystokinin (CCK), glucagon-like peptide (GLP-1), and glucose-dependent insulinotropic polypeptide were increased by 60, 65, and 36 percent respectively following the whey preload compared with the casein. The whey preload also slowed the rate of stomach emptying compared to casein. In addition, greater subjective satiety followed the whey test meal.
AviClin Summary: These results implicate post-absorptive increases in satiety hormones as potential mediators of the increased satiety response to whey and emphasize the importance of considering the impact of protein type on the appetite response to a mixed meal. StayFit Protein uses a combination of Whey Isolate and Casein to ensure improved appetite control.
More Muscle Less Fat
Simple Scientific Fact: The more muscle you build, the easier it is to lose body fat. After all, muscle is a highly metabolic tissue that requires a lot of fuel to maintain. The more fuel (calories) you burn, the less body fat you'll have. New research shows just how muscle influences fat burning.
Researchers from the University of Hawaii (Honolulu) genetically built overly muscled mice and found that their fat cells produced higher amounts of mRNA proteins--signaling agents that genes use to build specific proteins associated with greater fat-burning.
Also, muscles have much more mitochondria than other cells. Mitochondria are little organelles inside your sells that produce energy by burning fat.
So, if you want to get lean or stay lean, increase your muscle by working out 3 to 4 times a week and increasing your intake of Protein, the building block of muscle.
