Milk, answered
Milk has about 8.3 g of protein in 1 cup (8 fl oz), and about 12.4 g in 1 glass (12 fl oz).
About 122 calories in 1 cup (8 fl oz), or about 183 in 1 glass (12 fl oz).
Milk is a useful contributor rather than your main protein: 1 cup (8 fl oz) adds about 8.3 g, with around 27% of the calories coming from protein. It is a complete protein, so it carries every essential amino acid your muscles need to rebuild. Build the meal around a denser source and let milk top it up.
Not quite. Only about 27% of the calories in milk come from protein, short of the roughly 40% bar that counts as a high-protein food, so treat milk as a contributor rather than a main protein source.
