Forget dessert In “Got Data? Consuming calcium, dairy doesn’t keep off weight” (SN: 3/11/06, p. 147), you report, “Every 4 years, each volunteer completed a questionnaire about his body weight and dietary habits.” Any dieter knows that it is next to impossible to remember what one has eaten 4 days ago. Any more details on […]
