Frequently asked questions

  • How can I use Fitia to gain muscle?

    Fitia helps you build muscle by calculating your optimal calorie surplus, setting the right macronutrient balance, and providing a personalized meal plan rich in protein and essential nutrients.

    You can log meals, track your progress, and adjust your intake dynamically to maximize muscle growth while minimizing fat gain.

  • How does Fitia determine my calories for muscle gain?

    Fitia calculates your Total Daily Energy Expenditure (TDEE) using scientific formulas based on 150+ studies, considering your age, weight, height, gender, activity level and more variables.

    To promote muscle gain, it applies a calorie surplus based on your goal:

    • Lean Bulk (+5–10% surplus): Slower muscle gain, minimal fat gain
    • Standard Bulk (+10–20% surplus): Balanced muscle growth with some fat gain
    • Aggressive Bulk (+20–30% surplus): Faster muscle gain but higher fat accumulation

    Your calorie and macro targets adjust over time to optimize muscle growth and recovery.

  • Does Fitia provide a meal plan for muscle building?

    Yes. Fitia generates a science-based meal plan designed to fuel muscle growth.

    The meal plan ensures a calorie surplus to support muscle building, a high protein intake to enhance muscle repair and growth and optimal carbs and fats to optimize energy and recovery.

    You can customize your meal plan, swap meals, and generate shopping lists to simplify your meal prep.

  • Do I need to lift weights to gain muscle?

    Yes. Strength training is essential for muscle hypertrophy (muscle growth). While proper nutrition provides the building blocks for muscle growth, resistance training triggers the stimulus needed for muscles to grow.

    For best results:

    • Train at least 3 times per week with progressive overload
    • Eat enough protein to support muscle repair
    • Prioritize rest & recovery, as muscle growth happens outside the gym
  • How long does it take to see muscle gains?

    Most users notice initial strength improvements within 2–4 weeks, but visible muscle growth typically takes longer than fat loss, usually around 6–12 weeks of consistent training and proper nutrition.

    Muscle gain is a gradual process, as building lean mass requires progressive strength training, adequate protein intake, and proper recovery. Fitia helps you track your progress, adjust your intake, and optimize results over time.
