From Robert Bryan
Peter Aldhous reports that test subjects who make green choices subsequently exhibit a greater tendency to lie and that people who improve their homes’ energy efficiency thereafter use their heating more (27 March, p 11).
Is this a general facet of human nature that also exhibits itself in dietary choices? Does ordering a skinny latte result in a greater propensity to buy a slice of cake or a doughnut?
The prevalence of low-fat products could, therefore, cause weight gain, by giving one a licence to indulge in a fatty treat. I doubt that the fat in milk has a significant effect on a person’s waistline, but I’m pretty sure cakes and doughnuts do.
