Which is better whey protein powder or food proteen for someone who wanna ger rid of body fat and build muscle

Between the two, whole food proteins always wins out. The only exception is immediately before and after workouts.





Whey protein is a fast uptake protein that is quickly absorbed by the body. This means that all of it's quickly available after consuming. Whole food proteins are more ';time released'; since it takes them longer for the body to break down. Fast uptake is great for before workouts to help reduce the catabolic effects, and after a workout for quick recovery, but not so great other times of the day.





For mornings and before bedtime, a mixed protein source is best (a mix of egg, whey and casein proteins for example). During the day, lean whole protein sources are the best (fish, chicken, lean beef, etc.). These give the body a more constant supply of protein to use.





Edit:


The answerer below is actually incorrect about this but in his answer does not contradict my answer - look at any of the research done on different protein sources and the conclusion is the same; different protein sources are absorbed by the body at different rates. This is called the Biological Value of protein. Casein has a low BV, meaning it's absorbed much slower due to the micellar molecular structure of the protein. The same goes for chicken, beef and other whole sources. Egg whites have a slightly higher BV, and whole eggs have the highest BV of the natural sources (100).





Whole foods must travel through the small intestines to be completely broken down, which is what gives them the ';slow released'; effect, but little of it is actually ';destroyed'; (i'm not sure where that info comes from that whole protein sources are more ';destroyed'; than refined powders, I'd like to see the scientific article suggesting this). It's true that often an excess of protein is excreted, but sometimes it's converted to glycogens depending on the activity level of the person. This is an even better argument for whole food sources as fast uptake will be filtered out more since more of it becomes available all at once in the body - whole sources are more slowly released at a more constant rate, at a rate the can be used by the body at any one time and over a longer period of time.





Mixed proteins usually contain milk proteins (a combination of casein and whey), egg proteins and even soy proteins, and are optimal for mornings and before bedtime as it gives a mix of fast and slow uptake proteins.





Whey proteins, on the other hand, are a very high BV protein that essentially skips the small intestines and is mostly absorbed through the stomach, which allows it to hit the blood stream and muscles much more quickly and all at once, skipping much of the digestive process. This is why it's great for before and after workouts (giving the body what it needs immediately) but not so great at other times.Which is better whey protein powder or food proteen for someone who wanna ger rid of body fat and build muscle
A mix of supplemental whey protein and casein protein (derived from eggs) are the two best proteins for building muscle. It is best to get these proteins from supplements because, unlike in food, the protein in supplements has been refined and is easily aborbed by your body. The digestive system does not time release food proein like the previous answer suggests. Instead, your stomach acid and liver destroy most of the protein that you consume before your body can aborb it. Supplemental protein is much easier for the body to absorb and, thus, a much greater amount is absorbed prior to the digestive system destroying it.





In my opinion, the best protien supplement out there in terms of taste and effectiveness is muscle milk- http://www.supplementsoutlet.com/cytospo鈥?/a>
