On a segment titled “Food For Life” on his show “Sanjay Gupta MD”, CNN Chief Medical Correspondent Sanjay Gupta recently interviewed athlete Michael Arnstein.  Arnstein is an elite endurance athlete who follows a Fruitarian diet and consumes between 25-30 pounds of fruit a day, and little else.  After trying other diets and supplements, Arnstein believes that his fruitarian diet has delivered the best results. In the video, Arnstein mentions that he follows this diet mainly for performance-based reasons, and says that his marathon performance is constantly improving, stating that he feels “almost superhuman.”  He goes on to say that he eats up to 6,000 calories daily, 80-90% of which come from fruits, with the other 10-20% from raw vegetables, and he has only around 3-5% body fat.  He says that he rarely eats nuts and seeds, thus he believes that the best term to refer to his diet is Fruitarian.  Check out a video of the interview below:

Fruitarianism, also known as the 80/10/10 diet, is a raw food version of a low-fat, plant-based diet, similar to that popularized by Dr. Dean Ornish & Dr. John McDougall, which involves consuming mostly raw fruits, with less emphasis on raw vegetables and even less on nuts and seeds.  The meal plan and term were popularized by a nutritionist and raw food athlete named Dr. Douglas Graham.  Dr. Graham has a book available on Amazon that can serve as a good starting point for anyone who is looking to get started on a fruitarian diet plan.

Following a fruitarian diet can be tough, and it is often seen as a controversial plan.  Some nutritionists believe that such a diet is unsuitable for teens and wholly unsuitable for children, while others believe that adults should not follow a fruit-only diet for too long.  One thing to keep in mind though, as Arnstein states, is that to keep up with Vitamin B12, it is recommended to use supplements.

If you have any questions about Fruitarianism or the 80/10/10 diet in general, or if you’d like to talk about your own personal experience with this plan, feel free to leave a comment below!
