Watch former President Bill Clinton's interview with Sanjay Gupta about how he went from Omnivore to Vegan.

Dr. Sanjay Gupta's report on how your diet can literally save your life.

So what is a flexitarian? It is someone who has a predominantly vegetarian diet but that eats fish, meat or poultry on occasion. 

There has been a lot of controversy surrounding the flexitarians, who often call themselves meat-eating vegetarians, as a vegetarian does not eat meat ever. Moreover a vegetarian may have a political or environmental agenda behind his/her choice and so feels more resentful towards the part time vegetarian. 

So why become a flexitarian? 

Because the health benefits of a vegetarian diet cannot be negated and adopting it on a part time or mainly full time basis will have a positive impact on your health not to mention the animals.
