Calorie counter for weight loss
Calorie Counter for Weight Loss
Losing fat is simple in theory and brutal in practice: eat fewer calories than you burn, consistently, for long enough. The hard part isn't the math — it's logging honestly every day without burning out.
WhispCal removes the friction. A 3-second voice or photo log, a calorie **range** instead of one rigid number, and a target that quietly adjusts as you lose weight. Here's how to make a deficit actually stick.
Set a deficit you can live with
The fastest path to failure is the most aggressive deficit. Crash diets strip muscle, tank your energy, and trigger the cravings that end them. Aim to lose around 0.5–1% of your bodyweight per week — fast enough to stay motivated, slow enough to keep the muscle that keeps your metabolism high.
In practice that's a deficit of roughly 300–500 calories a day for most people. Build it from your maintenance calories rather than chasing a scary-low number, and protect your protein — it's what tells your body to burn fat instead of muscle.
- Keep protein high — around 1.8–2.4g per kg of bodyweight to preserve muscle and stay full
- Don't go below your BMR — eating under what your organs need backfires
- Use a range, not a single number — WhispCal gives you a target band so a normal day isn't a 'failure'
- Weigh weekly, judge by the trend — daily scale swings are mostly water
Why your target should move as you do
Here's the trap every diet app misses: as you lose weight, you burn fewer calories. The deficit that worked at the start slowly shrinks to nothing, and progress stalls even though you're 'doing everything right.'
WhispCal's Autopilot watches your real weight trend and nudges your target down as you slim, so the deficit stays honest without you recalculating anything. Metabolic Zone IQ spots when your metabolism is adapting and flags it before a stall turns into a quit.
Log fast or you won't log at all
Every abandoned diet app dies the same way — the logging got tedious. Weighing food and hunting for database entries is a chore nobody sustains for months.
With WhispCal you just say *"chicken burrito bowl and a flat white"* and it's logged in three seconds, with your remaining calories updated instantly. Snap a photo of your plate or scan a barcode when that's faster. The whole point is that it's effortless enough to still be doing it in week twelve, which is where the results actually live. It's free, with Autopilot and unlimited logging on the $4.99/mo plan, on iOS and Android.
Frequently asked questions
How many calories should I eat to lose weight?
Start from your maintenance calories and subtract about 300–500 per day — enough for roughly 0.5kg of fat loss a week. Eating far less rarely speeds things up; it just costs you muscle and energy. WhispCal sets this target for you and adjusts it as you lose.
Do I have to count calories perfectly to lose weight?
No. Consistency beats precision. Logging most days within a sensible range drives the result — which is exactly why WhispCal gives you a target band instead of one rigid number you're doomed to miss.
Why has my weight loss stalled?
Usually your maintenance calories dropped as you lost weight, quietly erasing your deficit — or water retention is masking real fat loss. WhispCal's Autopilot lowers your target as you go, and judging by the weight trend over weeks rather than days fixes the rest.
Should I do cardio or just diet to lose weight?
Diet drives the fat loss; training (especially lifting) protects your muscle and keeps your metabolism up. You can lose weight on diet alone, but adding resistance training makes the result look and feel far better.
