This documentary, hosted by Gemma Atkinson, explores the nation's growing obsession with protein, a macronutrient now added to everything from shakes and bars to yoghurts and puddings. Joined by Dr Jack Mosley and cookbook writer Lucy Watson, Gemma sets out to discover whether the hype, and the consumer anxiety driving it, is actually justified.

The programme investigates what's really inside these protein-packed products, questioning how much protein we actually need to stay healthy and how to separate good advice from clever marketing. Gemma also uncovers the psychological tricks advertisers use to tap into our collective "protein panic," pushing us towards specialised products we may not even need.

It's a timely investigation that cuts through the noise, giving viewers the information they need to make better choices in the supermarket aisle.
