Maybe not to lose weight, but as far as I know the primary goal of most people who take protein supplements is to gain muscle. From my understanding this is literally impossible if you don't consume enough protein. So the question of how much should you be consuming based really depends on your training level, goals, diet, etc.
> A 2014 analysis of 36 papers found that protein supplements have no impact on lean mass and muscle strength during the first few weeks of resistance training in untrained individuals.
Seems like any difference you would see with a couple few weeks of training would be a rounding error? In my experience, any noticeable differences in muscle mass require months of training.
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.
