I've never followed a vegan or vegetarian diet in the past but I think I could do it. It would not be easy. I have worked with nutritionists who have said a vegan diet is not necessarily all positive for your health because you need nutrients you only find in meats. I believe in a balanced diet.
It was a fantastic learning experience and OK I got slammed because I wasn't Audrey Hepburn but you could have predicted that really if you'd opened your eyes wide enough.
