.I had lost weight in my mid-30's through diet and exercise, but I never got to my goal. I had another kid.... turned 40... and nothing that I did seemed to help.
I did Crossfit over the summer which introduced me to Paleo. I had a few friends that had switched to a more Paleo type diet. Although they hadn't lost a lot of weight, they spoke of their energy, better sleep habits, clear skin, etc. I thought they were crazy- why would I do this if not to lose weight?
