I find myself repeatedly falling back on a few common wisdoms:
(1) All things in moderation
(2) It's not what you do, but rather how you do
(3) Perspective and context
(4) This too, shall pass
So, I have yet to find or hear of an exclusively vegetarian or carnivore that is "healthy". Those that call themselves that, and are healthy, when it comes down to it, are not exclusively one or the other, will take supplements, and will have other little "life hacks" that make it all possible. I am reminded of my own experience with fasting. If you read the scientific literature, many studies will say it doesn't work any better than calorie restriction, that is, until you get into the methods behind the studies and realize that the "fasting group" did not achieve a ketogenic state because the fasting group needed to fast, not 6-8 hours (as was done in the studies), but rather 12-18 hours, or more. "It's not what you do, but rather how you do." Some doctors will warn of electrolyte imbalances and say it can be dangerous, until you realize that most people who fast also take an electrolyte supplement. Furthermore, they seem to neglect all the many studies of Muslim folks who fast during Ramadan, and eat one meal a day and all the documented health benefits. They neglect the fact that up until some 150-200 years ago, the vast majority of the populous never ate any more than one meal a day. They also neglect the studies of nomadic African tribesmen who will walk, hike, and run for days without food before they kill an animal to eat. Talk about the potential for dehydration and electrolyte imbalances. Yet, humans have been doing this sort of thing since the dawn of man. Hmmm.
What we have is the food and pharmaceutical industries capitalizing upon the ignorance of people, their short historical memories, and the corporate marketing propaganda being bombarded upon people from the doctors in med schools, even making financial contributions to med schools, to the commercials on television, to well placed adds on all of our computer and phone screens. They subsidize all the nasty, artificial sweetened, hormone spiking, preservative-filled, crap that comes in boxes, bags, and cans to make them cheaper for the consumer, whilst purposefully neglecting the prices of fresh fruits, vegetables, and meats (making them more expensive). Now, we have "meat" created in laboratories, all based upon a "problem" that we have contributed to ourselves in the form of methane emissions, pesticide exposure, and contaminated water. They've literally and purposefully created a problem to be treated with the products they sell, noting how fat and unhealthy people are, and doctors who go through med school with grossly inadequate training in basic nutrition and lifestyle (on purpose), but rather the majority of it how to treat (not cure) with medications. "We've got a pill for that."
I've been in the medical field for nearly 40 years. I see what's going on here. It's a corporate, money-making machine, I dare say "criminal organization" at the very top, that happens to hire well-intentioned, caring, individuals to manage people at the bottom of the organization. It's as beautiful as it is twisted. I've seen "The Matrix" that is "the system" we live in. Now, are you going to take the "green pill" and go on as if you never heard of any of this, or are you going to take the "red pill" and open your eyes to what is going on around you.
