In general, a food or beverage composition in accordance with this disclosure typically comprises at least milk-based protein, carbohydrate, Vitamin D, calcium, and conjugated linoleic acid (CLA). The milk-based protein can be a blend of whey and casein. In certain exemplary embodiments, it may be desirable to deliver about 5 to 20 grams of milk-protein to a consumer. The composition includes carbohydrate to, in part, stimulate protein uptake into the muscle and replace carbohydrate used during exercise. In certain exemplary embodiments, it may be desirable to deliver about 5 to 26 grams of carbohydrate to a consumer. The composition further includes Vitamin D, which has been shown to play a role in muscle protein synthesis. In certain exemplary embodiments, it may be desirable to deliver about 98 to 1000 IU of Vitamin D to a consumer. The composition further includes calcium. Adequate calcium consumption is necessary to optimize the function of Vitamin D. In addition, calcium has been shown to improve fat metabolism which may possibly improve loss of body fat with strength training. In certain exemplary embodiments, it may be desirable to deliver about 350-600 mg of calcium to a consumer. The composition also includes conjugated linoleic acid. Conjugated linoleic acid has been found to increase muscle mass and decrease body fat in both sedentary individuals and athletes undergoing strength training. In certain exemplary embodiments, it may be desirable to deliver about 0.5 to 5 grams of conjugated linoleic acid to a consumer.Selon cette invention, dune manière générale, une composition daliment ou de boisson comprend typiquement au moins une protéine à base de lait, un glucide, de la vitamine D, du calcium et un acide linoléique conjugué (CLA). La protéine à base de lait peut être un mélange de lactosérum et de caséine. Dans certains modes de réalisation donnés à titre dexemple, il peut être souhaitable de distribuer de 5 à 20 grammes de protéine de lait à un conso
