I actually went high nutrient vegan 4 months ago and I love it.  I'm never looking back. I don't eat animal products of any kind.
Not even butter or cheese? That would be so hard for me
Nope, anything from animals as well so no dairy or eggs.  I thought it would be hard to give up cheese but there are substitutes and I really don't miss it because dairy wreaks havoc on your body and increases your risk for cancer.
What do you do about getting protein in your diet?
Low-protein diet
A low-protein diet is a diet in which people reduce their intake of protein. A low-protein diet is prescribed for those with inherited metabolic disorders, such as Phenylketonuria and Homocystinuria and reduced protein levels have been used by people with kidney or liver disease. Low protein consumption appears to reduce the risk of bone breakage, presumably through changes in calcium homeostasis. Consequently, there is no uniform definition of what constitutes low-protein, because the amount and composition of protein for an individual suffering
one. For example, rennet is sometimes made from stomach linings, yet is acceptable for making kosher cheese, but such cheeses might not be acceptable to some vegetarians, who would eat only cheese made from a vegetarian rennet.
Likewise, some products bearing a vegan certification label do not have the status in halakha as "pareve" due to incidental contact with dairy ingredients or utensils that render the item dairy, while still qualifying by the vegan certification as containing no animal products.
Pareve and allergies.
