The weight-loss injection Wegovy, if it lives up to expectations and is used widely, can set the imagination racing on possible consequences. Improved health will surely increase average longevity, with implications for pensions and care of the elderly. Lower average passenger weight will result in lower fuel consumption and lower emissions for aircraft. If progress to obesity is averted, fewer purchases of larger clothing will be necessary. On losing weight, many individuals may find it far easier to exercise more, with significant health benefits. The consequences may well affect some industries negatively, particularly those in food production, but the positive consequences are paramount (18 November, p 8 and p 48).
