Why I recommend a plant-based diet

A recent client asked me "Trisha, why do you prescribe a plant-based diet?  Of all the diets that exist, why this one?"

The answer is this… a whole foods, plant-based (WFPB) diet is the healthiest diet thats ever been scientifically studied (1).  It's the diet that can help you achieve optimal health and permanent weight-loss over the long-term.  Yeah for getting healthier and leaner every year without restricting how much you eat!

If the totality of research on a different diet was found to reverse severe heart disease, prevent cancer and help eliminate type II diabetes medications, then I would prescribe that diet!

No other diet has come close to getting the same results over the long-term.  

For example, Dr. Dean Ornish has reversed severe heart disease using diet and lifestyle alone in a 5 year study, while the control group that followed their doctor's advice showed heart disease progression (2).

Dr. Caldwell Esselstyn Jr. has also reversed severe heart disease in a 12 year study using a plant-based diet and cholesterol lowering medication in some patients (3). 

Dr. Neal Barnard has done extensive research on a plant-based diet and type II diabetes showing in some cases, that type II diabetes can be reversed, meaning no more medication! (4).

In addition, the World Cancer Research Fund recommends a plant-based diet for the prevention of cancer (5).

All of these amazing results can be achieved without calorie counting, portion restriction or pushing the plate away making it manageable over the long-term.  A WFPB diet is not a crash, fad diet that you have no other choice but to stop after one month.
