No matter which post-workout snacks you indulge in to get your mix of healthy protein and carbs, make sure you're hitting the recommended guidelines. "In general, the 2015–2020 Dietary Guidelines for Americans recommends that 10% to 30% of calories come from protein," Valdez says. "For a woman who weighs 120 pounds, they would need 65 to 92 grams of protein per day." As far as how much should be consumed post-workout, though, Rumsey says that "most women need around 10 to 30 grams of protein within two hours post-workout. This will depend on your size and your goals. If you're larger, more muscular, or looking to build more muscle, aim for 20 to 30 grams."
Just be sure to avoid too much after-workout protein, because according to Valdez, the limit does indeed exist. "The body cannot exceed 30 grams of protein at a sitting, which takes about two to three hours to be absorbed and metabolized. Anything more than that will be converted to fat if caloric intake is exceeded at that moment in time." In other words, eating too much protein is entirely possible. It's even possible to impede your fitness goals. "Eating too much protein can backfire and impair your muscle-building goals," Rumsey says. "While enough protein is needed to provide amino acids for muscle building and protein synthesis, once you meet those needs, the excess protein will be oxidized and used for energy." That doesn't sound too bad, right? Not so fast. "If you consistently eat too much protein, your body will make more enzymes that burn protein for energy. Since your goal is protein synthesis, not protein burn, this is not ideal."
