Calorie & macro tracking for a cut
How to Track Calories While Cutting
A cut isn't just weight loss — it's surgical. The goal is to strip fat while defending every gram of the muscle you spent months building. That demands a sharper deficit, ruthless protein, and a tracker you'll actually keep up with.
WhispCal handles the precision so you can focus on training hard and eating to a plan that holds your muscle in place.
Aggressive deficit, muscle-sparing execution
A cut usually runs a slightly steeper deficit than general weight loss — often 20–25% below maintenance — to lean out on a timeline. The risk is obvious: the harder you cut, the more muscle is on the chopping block. Three things keep the muscle and let go of the fat.
- Protein at the top end — 2.0–2.4g per kg of bodyweight, the most important variable on a cut
- Keep lifting heavy — train near your usual loads; that's the signal to keep the muscle
- Don't crash too fast — past ~1% bodyweight loss per week, muscle loss accelerates sharply
- Hold carbs as high as the deficit allows — they fuel the heavy training that protects muscle
Watch for metabolic adaptation
Cuts stall, and it's rarely a willpower problem. As you diet, your body burns less to defend itself — metabolic adaptation — and a fixed deficit slowly evaporates. Most people respond by slashing calories further, which only deepens the adaptation and bleeds more muscle.
WhispCal's Metabolic Zone IQ tracks this adaptation directly, so you can see when your burn is dropping and respond with a planned diet break instead of a panic cut. Autopilot trims your target as your weight falls, keeping the deficit real without the spiral.
Tracking has to survive a hungry brain
Late in a cut, willpower is thin and any friction is fatal to your logging streak. The apps that demand you weigh everything and search a database get abandoned exactly when precision matters most.
WhispCal logs a meal in 3 seconds by voice, photo, or barcode and keeps your protein and remaining calories live, so staying on plan takes almost no mental energy — the energy you don't have to spare on a cut. Free to start, Autopilot and Metabolic Zone IQ on the $4.99/mo plan, iOS and Android.
Frequently asked questions
What's the difference between cutting and weight loss?
They're closely related, but a cut specifically aims to lose fat while keeping muscle — usually after building it. It runs a sharper deficit with very high protein and continued heavy training, where general weight loss just targets the scale going down.
How much protein should I eat while cutting?
Push to the top of the range — about 2.0–2.4g per kilogram of bodyweight. Protein is the single biggest lever for keeping muscle in a deficit, and it's also the most filling macro, which makes the cut easier to endure.
How fast should I cut?
Aim for around 0.5–1% of bodyweight per week. Faster cuts strip muscle and crush training performance. If you have time, a slower cut preserves more muscle and is far easier to sustain.
Why has my cut stalled?
Metabolic adaptation is the usual culprit — your maintenance calories dropped as you leaned out, erasing the deficit. WhispCal's Metabolic Zone IQ flags this, and Autopilot lowers your target so you don't have to keep guessing.
