Whey protein is not a single protein but a collection of proteins and protein fractions (or peptides). Whey protein promotes weight loss in three important ways:
Eating fewer calories than we use for energy is still the only proven way to lose weight. However, not all calories are equal. Some calories - such as those from sugars and processed carbohydrates - increase our hunger and reduce our fullness signals. These types of calories leave us feeling even more hungry, and as a result, we eat more than we meant to. Most of us can resist hunger for a few days, but few of us can rely on willpower and deprive ourselves for more than a few weeks.
That’s why most weight-loss diets don’t last very long.
Gram for gram, calorie for calorie, whey protein produces far more satiety (fullness) than other foods. In a recent study from the University of Washington School of Medicine, When subjects ate unlimited protein, they unconsciously reduced their daily eating by 441 calories per day and lost almost 11 pounds on average in 12 weeks.
Why? Because they felt full and satisfied from the whey protein, so they naturally ate less.
Research has shown that whey protein reduces hunger the most. One study found that a whey protein “appetizer” reduced appetite for two hours, compared to just one hour for soy protein, while egg protein increased appetite.
What makes whey more filling? Whey has high levels of a peptide called glycomacropeptide (GMP), which is a powerful hunger-reducing nutrient. In addition to stimulating the production of CCK, whey protein lowers hunger by reducing levels of the hunger hormone ghrelin.
Another recent study found that a whey protein drink produced a prolonged suppression of ghrelin - which is critical for weight loss.
Whey also increases fullness by activating opioid receptors in the gut. The peptides found only in whey protein bind to these opioid receptors, which then send a feeling of fullness to the brain that signals your body to stop eating.
A fascinating new line of research suggests that whey promotes body fat loss by blocking fat storage. In a recent French study, laboratory animals fed whey protein had the highest levels of lean body mass. Scientists are discovering why whey protein boosts fat loss in dieters, and they believe two specific components of whey: branched chain amino acids (particularly
leucine) and a protein fraction known as ACE inhibiting peptide are important.
Exercise is essential to improve your health and for developing and maintaining a lean figure. High-protein diets have long proven to increase the effectiveness of exercise.
In a study from the University of Illinois, women followed two types of diets. A high-protein or a low-protein reduced-calorie diet plus an exercise program:
Losing muscle while trying to lose weight is one of the primary reasons women regain weight. When you use an ideal protein that is 100% Whey and not vegan or plant-based, you are protecting your muscle and targeting your fat stores.
Many studies have shown that weight lifting helps gain more muscle on a high-protein diet. The amino acid profile of whey protein makes it much better at building muscle than regular food protein sources such as beef and other protein sources such as soy, casein or egg.
In fact, only whey protein significantly improves body composition.
Nutracelle only uses 100% Whey Protein. Our products also have natural prebiotic fiber from the chicory root. This fiber slows the absorption of the protein, so your body can utilise almost all of it. Without this fiber, excess protein becomes excess calories, slowing weight loss.
So, how do you take advantage of all of this research to lose weight and improve your body shape with whey protein?
Not all protein is created equal. The highest quality whey proteins, like Nutralean's, are created through cross-flow microfiltration. This is a more expensive process that produces a very high concentration of intact proteins.
Many manufacturers have been exposed with protein spiking - using cheap fillers to mimic the nitrogen tests that commonly measure protein.
