MSG does me in.
I saw my pharmacist today for the first time in several months. He used to be HUGE, but he's lost so much weight. He has a ways to go, but he's not in imminent danger of death....seriously, he was. I asked him how he was doing it and he said he completely cut out processed foods. If it's not real food, he doesn't eat it. He was, and still is, too big to exercise but he is well on his way. I'm so very proud of him, and I intend to follow his advice.
