I am pretty sure they feel great.She may have that body, but does she feel as good as you? Doubt it!
I will also not describe myself as feeling great due to the restrictions: caloric, macro and food groups that I have to practice. I have not seen anything to support that my fitness/looks will improve with Primal the only win is the hunger better balanced with the caloric need. Which is a lot to be grateful for, but it is not a reason to feel smug, because I cannot say that these ladies experience hunger the way I did when I ate yogurts, fruit and peanut butter. Primal is not an easy way of eating for me, that's why it took me good 2 years to come to terms to the idea that I have to eat what I have to eat and ignore all the buts, not just of CW, but of more moderate approaches.
I believe that the end result of Primal for me if I persevere and stick with it will be that I will completely lose the ability to enjoy food. However, that might not be a bad thing. It's not a good idea to compare oneself to others. One has to do what one has to do.
