Frequently Asked Questions
How do I choose between the protein and steps calculators?
Use both! Protein calculator shows nutritional needs for muscle growth and recovery. Steps calculator quantifies daily movement's calorie contribution. Together, they provide complete nutrition and activity insights.
Should I follow both recommendations to lose weight?
The protein calculator shows your daily minimum to preserve muscle during calorie deficits. The step converter shows calories from movement. Together with overall calorie tracking, they help optimize fat loss while maintaining muscle.
How often should I recalculate my fitness needs?
Recalculate when: body weight changes 5+ lbs, training intensity increases significantly, or goals shift. Quarterly recalculation during active training phases ensures recommendations stay current.
Are these calculators suitable for athletes?
Absolutely. Set training frequency to "athlete" level for accurate protein ranges (1.6-2.2 g/kg). Both calculators serve casual fitness enthusiasts and serious athletes equally well.
Can I use these tools during phases of gaining or cutting?
Yes. During bulk phases, maintain high protein (1.6-2.0 g/kg) and track total activity. During cut phases, increase protein to preserve muscle and monitor calorie balance including step activity.
How accurate are the protein recommendations?
Very accurate. Based on peer-reviewed research ranges established for different goals and activity levels. Individual needs vary slightly, but ranges provided are scientifically supported.
How accurate are the step calorie calculations?
Approximate ±20% accuracy typical. Actual burn varies by fitness level, efficiency, and metabolism. Use as trend indicator; heart rate monitors provide better personalized estimates.
Can I track long-term fitness progress with these tools?
Yes. Recalculate periodically to see how recommendations change with weight/fitness changes. Tracking calculations over time shows objective progress independent of how you feel.
Are my fitness inputs and calculations stored?
No. Everything stays in your browser. We don't store, transmit, or track any fitness data. Your body weight, training details, and goals remain completely private.
