I found that I did not like the texture of baked protein goods - things like pancakes and muffins (made from protein powder) were nasty to me. I stuck with shakes or oatmeal for my breakfasts.
I really liked Chicken flavor soup (can't remember the brand); if you use a little less water than recommended, it makes a nice sauce to pour over veggies.
I liked the cheesecake pudding

and all the puddings I tried.
Didn't like Quest chips (texture again). I preferred protein pretzels or Kay's Naturals chips and cookie bites. But the Quest chips are unrestricted, Kay's Naturals are restricted.
I prefer Quest protein powder shakes over RTDs, but I always kept some EAS shakes in my pantry. For RTDs, I've also tried Muscle Milk Light 100 (not bad), Hydroxycut (hard to find in the US), Skinny Girl (bleh), and GNC Lean shakes (great flavor, but just a tad too high in protein).
Walden Farms: I liked the jams (still use them on occasion), the coffee creamers, and the 1000 Island Dressing (for Big Mac in a Bowl). I thought the maple syrup, the caramel dip, and the chocolate syrup was horrible. I used the mayo for mixing with tuna. I also still use the BBQ sauce sometimes.
Re: exercise. After one month in P1, I started walking daily. Over the course of two months, I worked up to walking 3-4 miles at a go. Then, when I had about 20 pounds left to lose, I started the Couch To 5K running program - which is more walking than running for the first month. I timed things so that I would be phasing off at the same time I reached the end of C25K, and ran a 5K race my first week in P3.
