In your article about the effects of not drinking alcohol for a month (19 May, p 7), you noted a drop in blood pressure and a 1.5 per cent decline in weight. I am not sure that all the benefits were the result of abstaining.
Participants had previously been drinking three bottles of wine a week, containing about 1700 kilocalories. Since the team did not see any (other) changes in their diet during the study, the participants were in effect dieting.
