Macro tracker for muscle gain
Macro Tracker for Muscle Gain
Muscle is built from two things you control: a small calorie surplus and enough protein to use it. Get those right alongside hard training, and the scale moving up means new muscle — not just a softer waistline.
WhispCal makes the protein habit effortless and the surplus precise, so you grow lean instead of just heavy.
Eat above maintenance — but only just
You can't build muscle out of nothing; you need surplus energy. But more food doesn't mean more muscle. Past a small surplus, the extra calories simply become fat. The sweet spot for most lifters is a surplus of around 5–15% above maintenance, or roughly 200–400 extra calories a day.
That should translate to gaining about 0.25–0.5% of your bodyweight per week. Faster than that and you're packing on fat you'll only have to diet off later. WhispCal's calorie range keeps you in that productive band without forcing you to hit one exact number every day.
Protein is the non-negotiable
Training is the signal to grow; protein is the material. Miss your protein and the surplus just makes you fatter. Aim for 1.6–2.2g per kilogram of bodyweight, spread across 3–4 meals of 30–50g so muscle protein synthesis stays topped up through the day.
This is where a tracker earns its keep. WhispCal keeps a running protein total all day, so you catch a 40g shortfall at 6pm — while there's still dinner to fix it — instead of discovering it tomorrow.
- Protein — 1.6–2.2g/kg, the engine of growth
- Carbs — your training fuel; keep them generous to lift hard and recover
- Fat — around 25% of calories for hormones, no need to go lower
Track the trend, not the day
Muscle is built slowly, so judge progress over weeks. If your weight isn't creeping up and your lifts aren't climbing, you're not in a real surplus — eat a little more. If the scale is jumping fast, you're gaining too much fat — ease off.
WhispCal's Autopilot reads your weight trend and adjusts your target to hold that slow, lean climb, so you don't have to recalculate every time the scale moves. Free to start, with full Autopilot on the $4.99/mo plan, iOS and Android.
Frequently asked questions
How many calories should I eat to build muscle?
Eat about 5–15% above your maintenance calories — roughly 200–400 extra per day for most people. That supports muscle growth while keeping fat gain minimal. Much more than that just adds fat you'll have to cut later.
How much protein do I need to gain muscle?
Aim for 1.6–2.2g of protein per kilogram of bodyweight per day, spread across several meals. Going much higher offers little extra benefit; the lower end already drives nearly all the muscle-building effect.
Can I build muscle without counting calories?
Beginners often can, especially when they're new to lifting. But to grow consistently without gaining excess fat, tracking a slight surplus and your protein makes it far more reliable — and with WhispCal it only takes seconds a meal.
Why am I not gaining muscle even though I'm eating a lot?
Either you're not actually in a surplus (your maintenance is higher than you think), your protein is too low, or your training isn't progressive. WhispCal confirms the first two by showing your real intake trend versus your weight.
