Protein is the one macronutrient where "am I getting enough?" is an honest question, even though many people are. Your body uses it constantly to build and repair muscle, produce enzymes and hormones, and support your immune system, and it keeps you full and satisfied after eating, which makes it central to managing appetite.
The people who tend to fall short are specific rather than everyone. Older adults are the clearest group, since the body uses protein less efficiently with age and appetite often drops. Beyond that: people in a calorie deficit or cutting, very active and strength-training individuals, and some plant-based eaters who haven't deliberately built protein into their meals. If you're not in one of those groups and you eat a varied diet with animal products, you're likely getting enough already.
Protein is easy to build meals around, with chicken, eggs, fish, and Greek yoghurt among the strongest everyday sources, plus lentils and beans for anyone eating little or no animal food.
A healthy minimum for most adults is around 0.8 g per kilogram of bodyweight a day, roughly 46 to 56 g for an average-sized adult. People who train for strength or sport generally need more, with common guidance landing somewhere around 1.2 to 2.0 g per kilogram depending on how hard and how often they train.
How much is right for you depends on your bodyweight, activity level, and goal. You can set your macro split freely in the app, and a target tailored precisely to you is available with Pro.
