I tend to eat a few protein bars each week – usually on busy days when I don’t have access to a kitchen. As a fitness journalist and coach, I do a bit of everything, but strength training is my primary form of exercise. Given protein’s established role in muscle growth and maintenance, the idea that I can take a 20g stride towards my daily target with a prep-free bar is undeniably attractive.
However, protein bars are also the subject of new Channel 4 documentary Joe Wicks: Licensed to Kill, and the show presents a far less favourable outlook.
