 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?
That's the first question everyone asks but most of us consume too much protein.  Its also in fruits and vegetables along with grains, nuts, and seeds. They found that a lower protein diet lowers your risk for so many problems like diabetes and osteoporosis/bone breaks.
That's very interesting. I may have to look into this further. I don't know where to start though as it seems overwhelming
Everyone is different.  I started overnight because my health was so bad with an autoimmune disease and chronic pain, but you can start slowly too...just taking things out and eating more fruits and vegetables.  Youtube is a great resource. You can also go vegetarian first and then slowly take out dairy and eggs.  Eggs are so bad for you.
