When I was taking my classes to be a Naturopath, my teacher explained about the three body types for men, and four female body types. I found out that I had a thyroid body type, the description fit me to a T.
She explained that my type preferred to be vegetarian but that it was very difficult for me to get enough protein for my body type. However, if you are vegetarian, don't worry, that may be fine for your body type, for me it wasn't the best plan.
At that time I had been vegetarian for 16 years, it went along with my whole yogic philosophy of not harming animals, ending world hunger, etc. There was no way I was going to eat meat!
As the classes continued, day after day, I began to realize and understand the huge positive impact and complete and total transformation to your health when you eat right for your body type.
I finally decided to try it out for myself. I started eating some poultry and fish. Although, continuing a mostly plant based diet....I began changing up my breakfast, I cut down on sugar and and I followed my body type diet. I swear, the results were nothing short of miraculous!
