'Proteinflation': Meet the people paying up to 100 for a bag of protein

Amarpreet Singh has been drinking protein shakes since he was 16. The 30-year-old, who lives in London and works in banking, started going to the gym at a time when he says protein supplements were mostly associated with bodybuilders. Fourteen years later, shakes are still part of his routine, but they have become considerably more expensive. He says a 4.5kg bag of the whey protein he buys cost around £60 in 2020. By last year, the price had gone up to £120, though he managed to get one from eBay for £90. Now the same bag is £170.
