How to use this calculator
Enter body weight, goal, age, walking frequency, and current protein intake. The result estimates daily protein and meal-level targets.
Calculate daily protein needs for walkers based on body weight, goal, age, activity, and walking routine. The result includes meal distribution and muscle-preservation status.
Enter body weight, goal, age, walking frequency, and current protein intake. The result estimates daily protein and meal-level targets.
The result shows whether current protein intake supports walking, weight control, and lean-mass preservation.
People with kidney disease or medical restrictions should follow clinician guidance.
A 180 lb walker aiming for fat loss may need about 130 g protein daily, or about 30–35 g across four meals.
Many active adults need roughly 1.2–1.6 g/kg, depending on goal and calorie deficit.
Fat-loss phases often use about 1.6 g/kg to help preserve lean mass and control hunger.
Walking alone is not usually catabolic, but dieting with low protein can increase lean-mass loss risk.
Lean meat, fish, eggs, Greek yogurt, tofu, beans, and protein-rich dairy can work well.
Either can work; total daily protein matters most, but a protein meal after long activity can support recovery.
