Hunger is some kind of starvation enforces us to eat. Some people are hungry all the time despite the large meals they eaten and the high blood sugar level they have.
The key of this mystery found in the small intestine (a part of the digestive canal and responsible for absorption of foodstuff), the absorption part of the intestine called microvilli with a brush-like structure allow disintegrated food to spread on a large area to be easily absorbed.
In cases of malnutrition, this brush-like structure destroyed leaving the intestine unable to absorb most of the foodstuff except the easy stuff, which are sugars and carbohydrates.
This puts the body in a state of starvation because no foodstuffs including proteins, fats and vitamins are absorbed in a proper way to nourish the body. The body feels starvation and make a decision to face it by deposition of more fats in the body.
Protein shakes are powdered whey or soy protein, flavored with vanilla, chocolate or strawberry easily reconstituted by milk or water. For some best protein shakes for women and men see this: http://proteinshakesforwomenworld.com. You will find there some really great information.
Protein in protein shake is in a liquid form, easily absorbed by intestine helps lower Ghrelin (hunger stimulating hormone) effectively suppressing the appetite.
Meat and chickens are also consist of protein, why did not they do the same action.
Well, it is a good question, meat protein strings are more complicated and tough to be absorbed by intestine, only healthy intestine with brush-like structure microvilli can do, makes it a very hard job especially with persons with malformed-intestine with destructed brush-like structure microvilli. The advantage of protein shakes that they are in the liquid form easily absorbed, nourish and rebuild the microvilli and maintain the brush like structure. Of course there are a lot of healthz foods best for weight loss, you can check them out here in the article from proteinshakesforwomenworld as well as in the article from webmd.
The repairing happened to the microvilli makes the body make the best use of all types of food, which ends the situation of starvation, and deprivation that the body lived in for a long time when the only absorbed food was sugar and sweetly stuffs.
Therefore, protein shakes help to lose weight by three ways:
- Increases metabolism rate by 10% (a common behavior for all proteins).
- Lowers Ghrelin (hunger stimulating hormone) effectively suppressing the appetite.
- Ends the state of starvation and fat deposition.
