Ask five people how much protein you need and you will get five numbers, usually delivered with total certainty. The honest answer is that it depends on your body size, how much you move, how much you are eating overall, and what you are trying to do. Ranges are more useful than a single magic number.
For most generally healthy adults, research on protein and body composition tends to cluster around roughly 1.2 to 1.6 grams per kilogram of body weight per day when strength training is part of the picture — meaningfully more than the minimum needed to avoid deficiency, and meaningfully less than the amounts marketed on the front of a tub. Needs can sit higher during intentional weight loss, when protein helps preserve lean mass, and for older adults, whose bodies use protein less efficiently.
The practical version: anchor each meal with a protein source you actually like, and stop there. Three meals with a palm-sized portion of chicken, fish, tofu, eggs, beans, dairy or a shake will get most people close to a reasonable range without a tracking app. If you eat plant-based, spreading intake across the day and combining sources matters more than it does for omnivores.
Two things worth letting go of. First, the idea that there is a hard ceiling per sitting — the 'you can only absorb 30 grams' claim is a simplification of a more nuanced picture. Second, the idea that a number on a label is the goal. Protein is a tool for keeping you full, protecting muscle and building meals you can repeat. If your intake is doing those three things, it is working.
