Use this protein calculator to set a practical daily target that supports training, recovery, fat loss, or muscle gain.
Suggested protein range
128-160 g per day
These estimates are starting points, not medical advice. Adjust based on real progress, recovery, and guidance from a qualified professional when needed.
A consistent protein target helps make training adaptations more likely, especially when strength training is part of the plan. Protein provides the amino acids your body uses to repair and build muscle tissue after each session.
A range is more useful than a single exact number because appetite, schedule, and food choices vary day to day. Hitting somewhere within your target range consistently is better than hitting an exact number sporadically.
Protein alone does not build results. Combine it with a repeatable workout plan and track progress over weeks. The combination of adequate protein, progressive overload, and recovery is what drives meaningful changes in body composition and performance.
Research consistently shows that protein intake within a range — typically 1.6 to 2.2 grams per kilogram of body weight for active people — supports muscle growth and recovery. The exact number matters less than consistent intake within this range. Some days you'll eat more, some days less. What matters is that your average intake over the week falls within the target. This is why the calculator gives you a range rather than a single number.
While total daily protein intake matters most, distributing protein across three to five meals can optimize muscle protein synthesis throughout the day. A practical approach is to include 25 to 40 grams of protein per meal. You don't need to hit an exact window post-workout, but eating protein within a few hours of training supports the recovery process. The most important factor is hitting your daily target consistently.
During a calorie deficit for fat loss, protein needs tend to increase slightly because higher protein intake helps preserve muscle mass while losing fat. Aim for the upper end of your range during cutting phases. During a calorie surplus for muscle gain, the lower to middle end of the range is usually sufficient because the extra calories themselves support anabolism. During maintenance, aim for the middle of your range.
If you're consistently losing strength during a calorie deficit, recovering slowly between sessions, or not seeing expected changes in muscle definition despite training hard, protein intake is worth reviewing. These signs can also stem from other factors like sleep and total calorie intake, so consider the full picture before making changes. A small increase of 10 to 20 grams per day is usually enough to test whether protein was the limiting factor.
