Protein bars

The program states that you can eat fat-free, sugar-free protein bars as snack on Attack phase but I can't find any. The closest is Quest and that contain Almond fat, not allowed. Any ideas?

I have not found anything compatible with the Attack phase. Perhaps, it's business opportunity for an enterprising company.
I decided to snack on fat free plain yogurt instead. You can also snack on a piece of turkey breast, a small oat bran pancake (i.e. egg whites, oat bran, fat free milk, flavor), a bit of fat free cottage cheese.

I learned a simple recipe called Muffin in a Minute (MIM) which used flax. I used oat bran, egg, hazlenut flavoring, ff plain yogurt, 1/2 tsp baking powder- mix together and put in a small microwave bowl, like a Rubbermaid 1 c. glass container. Microwave 1 1/2 to 2 minutes. Serve to self with 1 tsp sugar free maple syrup.

@cindy929 thanks for sharing this muffin recipe.

I have a wonderful snack and or meal replacement if you like Cheesecake or key lime pie. I use vanilla or key lime flavoring, depending on the weather and my tastes at the time. For a whole meal it is 1/2 cup ff Greek yogart, 1/2 cup ff cottage cheese, 2 to 6 packets of Stevia (i use Pur Via, cheapest at Costco), it works! It is about 210 calories depending on brand and the 1/2 portion will stave off hunger for 4 hours! That is just over 100 calories, sometimes I use ff ricotta instead for a texture change.

By the way I never would have made it this far without that and the sliced ham (Kirkland brand, Costco) Couple of slices are 60 calories or 4 slices for a meal, I know because I have done induction phase on Dukan at least 5 times now. Sometimes only 2 or 3 days of it, but the first time I did 12 days, and it was hard! BUT...when you can average 2 to 3 pounds a week and see and feel the results it is a goal worth a little work. If an old lady like me can do it anyone can!
