If you're trying to build muscle, protein is the most important macronutrient to track. You can be flexible with carbs and fat, but consistently hitting your protein target is non-negotiable for muscle growth.
How much protein do you need?
The research is clear on this:
- General fitness: 1.6g per kg of body weight per day
- Active muscle building: 1.8–2.2g per kg of body weight per day
- During a calorie deficit: Up to 2.4g per kg to preserve muscle mass
For a 75kg person focused on building muscle, that's roughly 135–165g of protein per day.
Why tracking protein matters more than tracking calories
Many people focus on total calories but neglect protein. This is backwards for muscle building. You can be in a perfect calorie surplus, but if protein is insufficient, muscle growth will be suboptimal.
Conversely, if you hit your protein target consistently, you have a lot of flexibility with everything else.
High-protein meals and snacks
Building a protein-rich diet doesn't require exotic foods. Here are reliable options:
Meals:
- Chicken breast (31g per 100g)
- Salmon (25g per 100g)
- Lean ground beef (26g per 100g)
- Eggs (6g each)
- Greek yogurt (10g per 100g)
- Lentils (9g per 100g cooked)
Snacks:
- Protein shake (25–30g)
- Cottage cheese (11g per 100g)
- Beef jerky (33g per 100g)
- Edamame (11g per 100g)
Timing your protein
While total daily intake matters most, distributing protein across 3–5 meals optimizes muscle protein synthesis. Aim for 25–40g of protein per meal rather than consuming most of it in a single sitting.
Post-workout protein is beneficial but not magical. A meal within 2 hours of training is sufficient — you don't need to chug a shake in the locker room.
How voice tracking helps
The challenge with protein tracking is knowing the protein content of everything you eat. This is where AI-powered tracking shines. When you say "I had a chicken stir-fry with vegetables and rice," the AI knows the approximate protein content of each component and gives you a running total.
No searching databases. No guessing gram counts. Just speak and track.
Key takeaways
- Aim for 1.8–2.2g of protein per kg of bodyweight daily
- Spread protein across 3–5 meals
- Prioritize protein tracking over calorie tracking for muscle goals
- Use voice logging to track effortlessly throughout the day
- Be consistent — hitting your target 6 out of 7 days beats perfection followed by quitting
