Beef is high in protein, B vitamins, minerals, and creatine. Lean red meat consumption has even been shown in some studies to increase the level of lean mass obtained with weightlifting. Even if you’re attempting to gain muscle, selecting beef that promotes muscle growth could be ideal without offering too many additional calories.
For instance, 3 ounces (85 grams) of 70% lean beef includes 228 calories and only 15 grams of fat. However, the same amount of 95 percent lean ground beef has a little more protein and only 145 calories and 5 grams of fat.
