Beginners do not have the muscular coordination for a while, unless they have done some sort of competitive sports before. This takes a while to develop, and if they go to the gym , eat as usual and add one or two protein supplements a day, it's doomed to fail.
Summary, their training intensity does not mobilize the body to process more protein and basically every meal would need to be conform.
The diet is really 90percent of all, everyone can train, but nobody wants to give up pizza and usual diet schedule. Personal trainers know that, but if they tell this to the customers, they will never see them again.
So they tell them white lies.
Building muscle takes a lot of time, consistency over long periods, it has to become second nature, else it won't happen.
In every gym, you see most people look the same every year, those are the ones.
Then you have the ones on performance enhancing drugs and the ones with proper diets, these will have the real results.
If someone gains 2kilos of pure muscle(not fat and water) in a year , it's a lot. That is like 175grams a month, so yeah, these studies are done by people who shouldn't have any business doing such studies.
They leave out too many factors, of course supplements will do nothing for a newcomer.
The only supplements that work you will find on the banned substances lists.
The next best thing is a proper diet. I think bodybuilding is a rather dumb sport, but they know how to diet, they have decades of pioneer experience.
