I came across this diet after sitting down one day and thinking "whats the most NATURAL food i can eat".... my whole life i have had digestive issues, and i'd plain had enough!!.......so i thought to myself " what did a caveman eat??"..... obviously not pasta and doughnuts!!.......i googled cavemans diet, and here i am!!..... Been eating this "diet" for about 2 years now....... i feel incredible when i stick to it, and cr@p when i don't. That's all the evidence you need to give it a good try.
Feel free to ask any questions as you go, especially if you want to tweek the stages ( which is perfectly fine to do)
Good luck
