Most of us need at least 50 grams of protein a day, and significantly more if we’re working out a lot or trying to lose weight. This graphic shows what 25 grams of protein looks like in a variety of foods, so you can eat a few of these portions and know you’re on the right track. Athletes need between 0.5 and 0.8 gram of protein per pound of body weight per day (so, 75-120 grams for a 150-pound person). Eating more than this is okay, as long as you’ve budgeted it into your calories for the day. You can get a 25-gram helping of protein from a small portion of meat, four hard-boiled eggs, or a cup of lentils. Check out the graphic for more examples from the plant and animal kingdoms.
