Sugar: counting the wrong calories.
Sugar is the substance that informs the body that what you are eating is good. Sort of like salt (except, we don't count the calories in salt): both substances will enable us to eat a lot more of whatever contains that substance that the same substance without that signal.
Put sugar and pasta, on vegetables, on dark brown bread, or broccoli, spinach, okra, hamburger, buns, ketchup, tomatoes, lemons, brusquely sprouts, eggplant... You will be able and eager to consume more.
Like the story of the man that carried a wheelbarrow of dirt out of the plant everyday... The dirt was searched, nothing found, day after day. Yet surely, he was stealing something! "Tell us, please, we'll stop searching, what are you stealing in the dirt?"
"I'm stealing wheelbarrows".
Sugar is the wheelbarrow that carries tons of calories, fats and carbohydrates, past the gate. (Notice how sweet the McDonald's hamburgers are).
Use sugar to your advantage: sprinkle on the things you know are very very good for you. You can even put sugar on those orange pieces of wood the Canadians call carrots: yum. That'll fill you up! Like salt, don't mix it in, but keep it on the surface, where the taste buds can find it. Yeah, its a trick, but they're only taste buds! No sin in tricking them.
