Billy chuckled, but she raised her hands in pretended shocked protest.
“Six thousand! Mercy! Bertram, I don't know what would happen if you ate that quantity; but I'm sure you couldn't paint. You'd just have to saw wood and dig ditches to use up all that vital energy.”
“Humph!” scoffed Bertram.
“Besides, this is for efficiency,” went on Billy, with an earnest air. “This man owns up that some may think a 2,000 calory ration is altogether too small, and he advises such to begin with 3,000 or even 3,500—graded, of course, according to a man's size, weight, and occupation. But he says one famous man does splendid work on only 1,800 calories, and another on even 1,600. But that is just a matter of chewing. Why, Bertram, you have no idea what perfectly wonderful things chewing does.”
“Yes, I've heard of that,” grunted Bertram; “ten chews to a cherry, and sixty to a spoonful of soup. There's an old metronome up-stairs that Cyril left. You might bring it down and set it going on the table—so many ticks to a mouthful, I suppose. I reckon, with an incentive like that to eat, just about two calories would do me. Eh, William?”
“Bertram! Now you're only making fun,” chided Billy; “and when it's really serious, too. Now listen,” she admonished, picking up the book again. “'If a man consumes a large amount of meat, and very few vegetables, his diet will be too rich in protein, and too lacking in carbohydrates. On the other hand, if he consumes great quantities of pastry, bread, butter, and tea, his meals will furnish too much energy, and not enough building material.' There, Bertram, don't you see?”
“Oh, yes, I see,” teased Bertram. “William, better eat what you can to-night. I foresee it's the last meal of just food we'll get for some time. Hereafter we'll have proteins, fats, and carbohydrates made into calory croquettes, and—”
“Bertram!” scolded Billy.
But Bertram would not be silenced.
“Here, just let me take that book,” he insisted, dragging the volume from Billy's reluctant fingers. “Now, William, listen. Here's your breakfast to-morrow morning: strawberries, 100 calories; whole-wheat bread, 75 calories; butter, 100 calories (no second helping, mind you, or you'd ruin the balance and something would topple); boiled eggs, 200 calories; cocoa, 100 calories—which all comes to 570 calories. Sounds like an English bill of fare with a new kind of foreign money, but 'tisn't, really, you know. Now for luncheon you can have tomato soup, 50 calories; potato salad—that's cheap, only 30 calories, and—” But Billy pulled the book away then, and in righteous indignation carried it to the kitchen.
