I'm thinking about doing a whole 30 for January. Its fairly strict, but it's all whole foods and doesn't really require "special" foods. Its based on the book "It Starts With Food".
The Whole 30 "rules" involve choosing:
healthy high quality protein (preferred grass fed and pastured/organic meats and eggs, wild salmon, no nitrates or sugars or fillers added to bacon, sausage, etc)
Lots of healthy fresh vegetables except no white potatoes
Healthy fats including olive oil, coconut oil and coconut, avocado
NO sugars, sweeteners, non calorie sweeteners, soy, food additives like carageenen
NO GRAINS, NO DAIRY
So the "requirements" of the whole 30 seem tricky in some aspects and fairly easy in some as well! I'm looking forward to giving it a trying it out! For me, I anticipate the hardest part to be some of the sneakier additives, like carageenen in my almond milk, etc.
