Protein coffee is merely coffee combined with a protein supplement, typically whey or casein. Its efficacy for weight loss is primarily due to increased satiety, potentially reducing overall caloric intake, not 'burning fat faster' inherently. It absolutely does not replace all meals; that's dangerously misguided. Furthermore, achieving a 'shredded' physique requires consistent diet, rigorous training, and time—not a single beverage 'overnight. And regarding wrinkles? That's an entirely unrelated biological process. Stick to a balanced diet and proper skincare for that.
