Yes, there are 7 billion people in the world. Many signing up for stranger more invasive studies with less important results - so, no it's not far fetched by any means. It's a very simple study. Feed 50 people pure protein shakes for a month. And feed the other 50 only sources of food protein (no vegetables, carbs or any other food that would interfere with the results) just meats/eggs, etc. Take accurate muscle mass measurements before during and after, place them on identical workout regimens using body weight percentage to account for how much weight they use. See who gains more. And there's your study.
Yes, it's called Atkins
The study is not about only consuming whey or only consuming meat, obviously in the real world people can eat salads, carbs, etc. but as their main protein source, can choose to only eat WPI. that's what this whole topic is about, meat vs. WPI - obviously you need other nutrients to live, this is just comparing the muscle growth benefits between only the WPI and meat. So in order to do that, you need a clean test. People verrrry frequently run all sorts of crazy metabolic, anabolic studies that are far more complex than this. Now, I don't have the answer regarding WPI and food protein regarding which is better for protein synthesis, but I haven't read anything on here that shows anyone else does definitively either. It's all anecdotal evidence, which in the scientific world, amounts to nothing. Also, not to say the participants in the study could be given a daily vitamin to make sure they're receiving some of what they need.
First of all, no eggs in protein shakes, Im talking about pure whey isolate only. And n, for a month, there would be no vegetables. Atkins doesn't encourage vegetables, you can have a tinnnnny amount of green lettuce before you breach your 20 carbs a day rule. But many people skip veggies all together, and you would have to for this.
Re: fiber - maybe each participant would be allowed some beneful (fiber mix drink) - youd obviously have to work out the fine details, but on the macro, there's no problem with this study for a month.
Your idea is far from practical and you have to realize that what you want is impossible to design in a study. There are a myriad of variables that you'd have to account for and the adherence rate would be so low that it would negate the results. Nobody is encouraging only using WPI as their sole protein source as that makes no sense. A huge part of the reason for protein shakes is practicality in that it is difficult for most to consume the protein they need from just whole foods.
If your still arguing your point I’m going to take you for a troll who just wants to argue for the sake of arguing
