Weight-loss drugs are probably playing a part in the slight dip in obesity in the US. But like many other parts of the world, the country has seen high inflation during the past few years, which has caused a cost-of-living crisis, raising food and energy prices. The consequence has almost certainly been lower food consumption and possibly less use of vehicles to save money, which would probably affect the rate of obesity (11 January, p 10).
