I trace seven major changes behind Britain’s rising obesity rates, from the arrival of McDonald’s and central heating to larger portions, desk lunches, constant screens, delivery apps and ultra-processed food. Along the way, I look at the dates, prices and research that reveal how ordinary routines gradually changed. I also explore Britain’s sugar tax, restrictions on high-fat, salt and sugar promotions, and the early evidence that changing the environment may work better than simply blaming individuals.
