Careful, this is totally incorrect. While we can eat meat (just like dogs CAN eat vegetables), we're not designed to be omnivores/carnivores.Millions of years of evolution has physically conditioned our bodies to be omnivores. Even our tooth structure, digestive enzymes, etc., are all clearly omnivorous. There are micronutrients essential to human health which are much more abundant in animal foods than in plant foods. As a result, if you want to go totally herbivore, you need to be extremely careful in managing your micronutrients in a way that omnivorous diets donʼt require. Itʼs a lot of work and most people get it wrong.
Our tooth structure is very similar to chimps, who eat a predominantly plant based diet (fruits mostly). And if you want to get really scientific, while some apes/chimps do hunt, their total protein intake from animal sources is less than 5% of their caloric intake, which is basically nothing.
Digestive enzymes - compared to a carnivore or omnivore, we're not even close to being able to digest meat well. The digestive enzymes that we have are designed to break down small amounts of protein (found in fruits/veggies, etc). Even the concentration of these protein digesting enzymes is somewhere like 1000X less concentrated than that in a dog. Humans digest very little of the meat they consume (I think it's somewhere around 20%). Even looking at our digestive track and the length of it, it's much more similar to a herbivore than a carnivore/omnivore as it has a longer digestive tract. Carnivores have very short digestive tracts in order to expell the meat they consume faster, while herbivores are long to absorb more nutrients from their food and break it down further. (side note, protein that stays in your gut for too long eventually begins to rot...)
The only micronutrient that would be more abundant in meat products COULD be B12, everything else is easily sourced from plants.
Now, while there are some people who are vitamin deficient who go on plant based diets, if you go whole foods based you should be ok. Because keep in mind, you can still be vegan by eating potatoe chips and bread all day, in which case you wouldn't get any nutrients/vitamins.
Testosterone....what?? Your body builds it's own testosterone, especially if you work out lifting weights. You don't need an external source of testosterone. If anything eating meat products would throw your hormonal balance off, not help it.
This is because you were working out hard, not because you were consuming more meat. Exercise and lifting weights increases testosterone production which in turn increases sex drive. I'm willing to bet if you didn't work out and went on a mostly meat based diet your sex drive would plummet.I felt great, looked great, and I seem to remember my sex drive was better than usual.
