This isnt about a commerical per say but I recently had a co-worker who was doing all the right things when it came to weight loss. She would work out, drinks lots of water etc, expect when it came to the food she was eating. She would bring Lein Cusines and weight watcher meals, stick it in the micorwave and eat it like candy. Then shed complian about no weight loss. I laughed and said well no wonder with what you eat. She said what do you mean? This is diet food! I promptly showed her the nutrional facts and she said shes neveractually read that. She goes by the front where it says low fat! low sugar! no carbs!..pfft I told her she would be better off making those same meals herself..so now she does :)
