Vegan eating with a focus on choosing healthy options 70-80% of the time, and less healthy (processed, "junk", etc.) the rest of the time.
Basically, an "everything in moderation" approach to a vegan diet.
A big focus on whole grains, vegetables, fruits, healthy fats, and beans.
Eat when hungry, even if it's every 2 hours. I highly encourage three meals and three snacks a day.
