Eating can be comforting when we are depressed or stressed. How many times do we reach for food when we aren't hungry? If you're like me it's a lot. I'm bored, had a herbal sexual enhancement disagreement with someone, financial stress, etc. We all do it. The trick is to realize it and go get a glass of water.
Growing up in the sixties and seventies it was rare to see people overweight. I remember the first television our family owned. It was a second hand, black and white with three stations. We watched it in the evenings after my father watched the news. My siblings and I spent most of our days out of doors with the rest of the neighborhood kids. The bottom line is we burned a lot more calories than we took in.
