It is a good bet you are not eating enough protein each day. Government survey data shows the average American man eats somewhere between 90 and 100 grams of protein a day, while the average woman takes in closer to 65 to 75 grams. Every five years, the federal government updates the Dietary Guidelines for Americans, and the newest version, covering 2025 through 2030, raised the recommended protein range to 1.2 to 1.6 grams per kilogram of body weight. That's nearly double the old standard of 0.8 grams per kilogram, a number that had stood for decades. Under the old 0.8 gram standard, you'd be aiming for around 54 grams of protein a day.
