I don't understand. Before I was married, I would eat 2 Whoppers with cheese, fries, and a soft drink nightly for dinner. Most of the time lunch was at Burger King as well, or it would be another such food from the student union at school and later ordering lunch delivery at work. I could empty a large bag of potato chips in one sitting. I'll admit, I was a pot smoker back then (I'm not ashamed of that) and it was also possible to put down an entire package of Oreos. I was 175-180 lbs.
Today I am married. I eat vegetables from my own garden (no pesticides or artificial fertilizers) and meat from my father-in-laws mini farm (completely grass fed and no injections or hormones.) I very rarely eat any kind of chips and the "sweets" we eat would be of the variety that my wife bakes from occasionally brownies (not all that often) to chocolate cake (again, not all that often) to through the summer majority of it is apple pie and peach cobbler right from the apples and peaches I pick in my own yard of which sees no insecticides at all. I now am at about 235.
So what is this about getting fat eating fast food?
