This diet will get you sick real quick.  I've never met a healthy-looking vegan.  Only go vegan for SHORT (a few days, here and there) bursts, as a detox. 

Green, leafy veggies should be cooked in olive/coconut oil, to break down the oxalic acids and help the body absorb nutrients.  Green, leafy veggies should only be eaten raw in small quantities (and not everyday).  If eaten raw, will build up oxalic acids and this will damage your kidneys.  And you will get thyroid problems.  And/or gout.

Legumes, nuts are also high in oxylates...these chemicals make it hard for the body to absorb nutrients. 

(Some veggies are ok to eat raw - i.e. carrots, tomatoes (actually a fruit), cucuмber, etc).  The healthier veggies (dark green) should be steamed/lightly cooked.

Also, calcium and dairy products bind with oxylates and help the body GET RID OF THEM, because they're dangerous.

The best diet is keto and/or paleo.  Grass-fed meats, animal fats (natural butter), whole milk and slightly-cooked veggies.  Rice is ok.  Good breads are ok in moderation.  If you eat a lot of good meats and natural butter, you'll feel full and won't have carb cravings as much.

Most vitamins from food are FAT SOLUBLE (vitamins A, D, E, K).  If you don't eat good fats, your body won't absorb these vitamins...no matter how many smoothies you drink.  Low fat diets are horrible, because your body will become deficient, due to being unable to absorb the vitamins in needs.

There are certain vitamins (B vitamins) which can ONLY be gotten from beef/animal products.

Dr Adkins was right -- a high protein, low carb diet is the way to go.  Eating like our "great grandparents used to eat" (i.e. the diet of a farmer) is the way to go --- eggs, meat, chicken, cooked veggies, milk --- this is the key to heath.

The main problems of health today
1) plant fats -- soybean, canola, peanut, etc....all are highly processed.  Cause inflammation in the body.  Simply horrible.  Use natural butter.  Olive oil is good too.
2) processed sugars -- high fructose corn syrup kills your liver and pancreas. 
3) pesticides in foods.  Non-local, non-organic.

The keto/paleo diet solves for all 3 problems above.

I did the carnivore diet for a short while and I didn't get bloated. I mostly did it as a reset to my gut and elimination diet. Eating raw veggies can cause bloating because of antinutrients. Even grains and beans have to be soaked, sprouted, or soured to break down the phytic acid to make them more digestible. Also, tofu has soy and that's an estrogen food which isn't good for men.
