On October 9, 2026, protein was everywhere again — in supermarket marketing, gym advice and social-media meal plans — prompting nutrition writers to ask a plainer question: how much do most people actually need, and who is paying a premium for a label they could satisfy with an ordinary lunch?
Start with the established numbers. The standard recommended dietary allowance sits at about 0.8 grams of protein per kilogram of body weight per day for adults — a minimum to avoid deficiency, not an optimum for every goal. People building muscle, dieting, or ageing (when muscle becomes harder to keep) generally do better somewhere in the range of 1.2 to 1.6 grams per kilogram, spread across the day; endurance and strength athletes may go higher under dietetic guidance. Against those figures, the surprise of dietary surveys is how many adults in wealthy countries already meet their target from normal meals — eggs, dairy, legumes, grains, meat — without a single product marketed as “high protein.”
That is where the marketing test bites. Protein genuinely matters — for muscle, satiety, recovery and healthy ageing — but a protein claim on a biscuit does not improve the biscuit. Nutrition writers’ useful test, per the reporting, is whether a product improves the whole diet or merely rents a health halo: check the sugar, salt and fibre riding along with the added protein, compare the price per gram against milk, yoghurt, lentils or eggs, and ask whether the food earns its place before the label does. Protein-enriched versions of foods that were never nutritious often cost half again as much to deliver what a cheaper staple already provides.
Where the extra protein earns its keep
There are people for whom deliberate protein strategy is medicine, not marketing: older adults fighting sarcopenia, patients recovering from surgery or illness, athletes in heavy training blocks, and people in calorie deficits determined to lose fat rather than muscle. For them, convenient high-protein products can be a rational tool. The error is universalising their needs into a grocery aisle.
The trend will keep spreading because it promises a single lever for weight, muscle and energy at once. The lever exists. Most shoppers, the evidence suggests, are already holding it — in the ordinary meals they were eating before the labels changed.
