I just had a thought like "What if some UFO aduction experiences people claim to have are actually people being kidnapped by the CIA" 
The kind of stories I'm thinking about often go like: "I was driving on an empty road in the middle of nowhere. I saw a bright light," and then either "I remember nothing but had lost time" or "I remember being experimented on by aliens and then put back in my car."
My tinfoil hat side is thinking like, these stories started happening around the time the US admitted to experimenting with abuse, torture and psychoactive drugs in Project MK-Ultra. Alien abduction stories were the most prevalent during this time. (CW: Just a heads up. If you want to read the rest of this post or anything else about MK-Ultra, be warned that it's pretty horrible, and involves some of the most disgusting torture I have ever read about. Death to America.)
Of the surviving documents released to the public about MK-Ultra, the CIA admits to: "kidnapping people it deemed "expendable" to undertake various types of torture and human experimentation on them. The prisoners were interrogated while being administered psychoactive drugs, electroshocked and subjected to extremes of temperature, sensory isolation and the like to develop a better understanding of how to destroy and to control human minds."
Part of me wonders how many of these alien abduction stories are just people being kidnapped, drugged with powerful hallucinogens, experimented on and then released with the suggestion conditioned into their mind that it was aliens.
The most famous alien abduction story is that of Barney and Betty Hill, an interracial couple that were both civil rights leaders, definitely people that the CIA would want to fuck with, especially during rising tensions with the Soviet Union, the US government was suspicious of minorities and anyone interested in their rights.
I mean if you're trying to gain weight and muscle simultaneously in a healthy manner (so without resulting to "dirty bulking" and still doing cardio) you're going to need to eat a lot of food, including a ton of protein. Not as much as some crazed bodybuilder throwing meat and eggs in a food processor or the 1g per pound of bodyweight myth, but around 1.8g of protein per Kg of total lean mass that you currently have on the high end, and then adjust once you've gained weight. Some people will eat more protein just to get a calorie surplus in, because they're tired of eating so much carbs and fat. If you've been there, you'll know the feeling.
The thing is, the vast majority of people are not taking part in some conscious effort to gain muscle and/or weight, so they don't need anywhere near that amount of protein.
I meant just for regular people who maybe work out once or twice times a week and aren't trying to bulk up. I doubt serious bodybuilders are eating protein candy bars from the grocery store anyway.
This theory falls apart at the protein candy bars, most of the protein supplements are plant based, it's exponentially cheaper
Most people won't be able or willing to eat the amounts of chicken or tuna to get the protein macros needed for reasonably fast gains, so they'll just get a bag of whey protein and protein bars to get there
