The metal taste is aluminum based preservatives, most people are desensitized to the taste but it comes back if you not exposed to it for long enough. Its not particularly unhealthy but makes everything taste like garbage when you can taste it. 
Bitter water is what veggies normally taste like, you can desensitize yourself to it like the aluminum though if you eat them enough. It takes a lot longer.
I won't suggest cutting meat out entirely, but you don't need much high protein food if your not working out. You should probably find a good butcher to help you find some really clean high quality meat to eat once a month or so. Maybe nothing too fatty, since you likely won't have much fat in your diet and it'll make you sick. 

Be couscous of after spiritual diets long term. There's a good reason fasting is common spiritual practice, because starvation is a psychoactive. Its a useful tool, but malnutrition is not enlightenment. 

Final note: Being vegan long term is only possible is a crazy global economy with access to crops and supplements from around the fucking world. Hominids can eat plants, but must eat meat in the wild. Also plants feel pain too. Nothing moral or natural not eating any meat or dairy.

>Being vegan long term is only possible is a crazy global economy with access to crops and supplements from around the fucking world.
literally the dumbest claim I've seen in a long time
humans are monogastric herbivores, we don't need supplements at all when eating a 100% plant-based diet
>Hominids can eat plants, but must eat meat in the wild.
you just outdid yourself and wrote something even more dumb
humans don't just have zero nutritional requirement for dead animal remains, but it's actually extremely toxic to human physiology
in fact, the human lineage is unique in that our CMAH gene was deactivated ~2 million years ago, rendering Neu5Gc from mammal remains toxic and causing system-wide chronic inflammation
not even chimpanzees, which have zero nutritional requirements for dead animal remains either, and only some of whom hunt, have this deactivation
educate yourself, moron
>Also plants feel pain too.
are you trying to be as braindead as possible?
first of all, that's false, plants are not conscious
secondly, even if they were, animals consume orders of magnitude more planet matter
that retarded argument fails on every level imaginable
>Nothing moral or natural not eating any meat or dairy.
it absolutely is both
dead animal remains and other animal products are toxic garbage to human physiology

Do you have a list of foods or a link to a diet you would support?
gpt
the vast majority of your food should be from fresh and ripe fruit, including 100% fruit juices provided they are made with ripe fruit and aren't acidic
then to 'supplement' that, you should be eating young and tender greens (alternatively parboil mature greens to make them edible and remove toxic compounds), various starchy tubers and roots, and to a smaller extent seeds like pulses and nuts, even to a very small extent grains

Where does that fruit come from in the winter? Where does most of it come from in the first place? Who grows your tubers? You realize that tender greens are seasonal in most of the world, right? Same with your nuts. This is a healthy diet, but is an extremely modern on. Most domestic animals only exist because they were both a necessary for nutrition and food storage. Please tell me diet, I really do what to know. 

Meat in excess does cause mild inflammation, but if this crazy system wide problem was so bad most people would be fucking dead. Same as the gluten bullshit, its just marketing. People have been eating meat since before they invented language. You teeth are sharp. You eyes are faced forward, for stalking pray. Your arms and shoulders are shaped perfectly for hurling projectiles. 8000 years worth the evidence left burned into the ground and cut into the bones of every large bodied animal they killed suggest out ancestors where nothing less than the fiercest predator to exist. That's not from hunting apples.

How did eating meat even begin if its unilaterally bad and natural? Even cows will eat other animals when they get the chance. 100% veganism is for hipsters and fungi.
