Why some people fail on a vegan diet

I thought I might do my own rant on the subject of why people transitioning to a vegan diet might fail.  Let me start is with listing all possible reasons:

• Poor motivation to become a vegan in the first place,
• The vegan diet they tried was an unhealthy one,
• They did not give sufficient time for gut bacteria to change, and finally
• It was not a lifestyle change

As you can see, on the surface, this is not a big list.  But inside these bullet points there are some big subjects. Let's start out with motivation.

Motivation: People usually wish to become vegan for one or more of three main reasons: personal health, animal welfare or the health of the planet.
