Why Protein Is the Hardest Macro to Hit on a Budget
Protein is a macronutrient composed of amino acids essential for tissue repair and muscle maintenance. The NHS sets an adult daily intake at 0.75g/kg body weight, which means a 70kg individual requires about 52.5g daily. Protein tends to be pricier per calorie than carbohydrates or fats, making it the hardest macro to meet affordably. Animal sources like chicken breast cost around £7 per kg, delivering roughly 31g protein per 100g, while plant-based options often provide less protein density. This price-to-protein ratio challenges those on tight budgets. Protein quality also matters; complete proteins contain all essential amino acids, found mainly in animal products and some plant combinations. Understanding these factors helps optimise cost without sacrificing nutritional adequacy.
