The 3 Week Diet
Questions & Answers

You can have anything that will substitute protein but just be careful of how many carbs are in any substitutes... I personally ate and still eat lots of chicken, turkey and cauliflower etc. to get my protein...

I don't eat beef and fish and I'm doing fine with eggs and chicken breast. You can also use Turkey breast. It still works with just that.
I am on day12 of this diet and I have lost 2inches from my stomach, 3inches from my thighs and 1 inches from each of my arms and hips. I hate using weigh it sets some of us back.

You can also have chicken, turkey, whey protein (less than 3 gram sugar per serving), or eggs as an "approved protein" on the diet.
