Description
USN Diet Fuel Ultralean 1kg is a 1 kg tub of USN Diet Fuel Ultralean, a high-protein, lower-carbohydrate shake with a full vitamin and mineral complex, designed as a light meal replacement during a diet.
Each 55 g serving gives around 200 kcal with 25 to 26 g of protein, 14 to 17 g of carbohydrate and a source of fibre, plus 24 vitamins and minerals. Protein contributes to the growth and maintenance of muscle mass, and the shake contains Tolerase L lactase to help digest the dairy. Use it to replace one or two meals a day alongside a calorie-controlled diet, or as a high-protein snack.
