"1970s (?) ad for sugar, showing a woman licking an ice cream cone. Text reads: ""Enjoy an ice cream cone shortly before lunch. Sugar can be the willpower you need to undereat. When you're hungry, it usually means your energy's down. By eating something with sugar in it, you can get your energy up fast. In fact, sugar is the fastest energy food around. And when your energy's up, there's a good chance you'll have the willpower to undereat at mealtime. How's that for a sweet idea? Sugar... only 18 calories per teaspoon, and it's all energy."""
