Effective bodybuilding relies primarily on resistance training and adequate overall daily protein intake, which can be successfully achieved through whole foods rather than specialized protein shakes.
The claim states that effective bodybuilding can be achieved without protein shakes. Multiple studies show that whole-food protein sources (such as rice protein or lean meats) achieve comparable adaptations to whey supplements, and overall dietary protein intake can meet physiological demands without supplemental powders. Therefore, the claim is supported.
