Now the last part why someone would go vegan. Because they think they can lose weight probably, or are too scared of the thought of an animal dying. You can go vegan, for a while have have AMAZING results as you are effectively going into a full detox mode (you can do similarly on a water diet but much faster); But plants can't give you everything you need. After about 2 years (if the youtuber vegans channels back in 2019 were anything to go by) they develop terrible debilitating diseases which is purely from malnutrition, because certain nutrients they had stockpiled in their cells/liver when they started is now empty. Certain fatty acids and vitamins you just can't get elsewhere. Those vegans have some fish or a hamburger and the problems instantly went away.
So long and short. Go vegan/vegetarian if you want, but set time aside, one meal a month or something to have some meat. We don't need a lot of it to get by, but you do need it.
ehh so i have some thoughts.
Vegan youtubers make up a small minority of a much larger group, and of those all have their own ideas of how to live as vegan. while i dont keep up with vegan youtube anymore, one creator i used to watch frequently was
Unnatural Vegan, who regularly releases videos disproving a lot of talking points made by more extremist, fringe vegan youtubers or groups. Her videos were really informative when I was first reading up on vegan diets and i'm glad i found her instead of, like, freelee the banana girl.
Yes malnutrition is a thing but so commonly it happens by over-restrictive diets that don't take into account the various vitamins and supplemental nutrients that you don't get by eating buckets of kale. (maybe kale was a bad example because it has a lot of vitamins actually lol) I've definitely seen vegan youtubers promote dangerous vegan diets, but i've also seen an uptick in all raw meat diets being promoted as well which are just as extremist and unhealthy. Neither are new, but the "veganism=malnurishment" argument is easily disproven when you meet (meat?) real vegans who have been living plant based for decades, healthily.
There are numerous ways of being able to meet all of your dietery needs without meat or animal products, fatty acids and vitamins included, without resorting to taking five horse pills to make up for what eating five bananas in a row can't give you.
And while trendy, extreme plant based diets are a thing, more so in the last decade with the rise of conversations about veganism, dismissing the movement as a whole discounts the fact that
people have been doing this for a while now.
another thing i'd like to note, I would look into more recent & peer-reviewed research regarding dieting and nutrition, as Harvey Diamond is considered a quack; a quick google search turned up
this article by dr. James Kenendy who did an extensive write up disproving much of what he and his wife/co-author Marilyn wrote about in their diet books.
Not attacking you btw! their books have been widely circulated since the 1980's despite neither of them (seemingly) having any background in nutrition.
