What's the 'right' pace?

Losing: 0.5–1.0 % of body weight/week. Gaining: 0.25–0.5 %. Faster works — but it costs muscle or adds fat.

Why isn't my deficit shown as a % of TDEE?

Deliberate: pace (kg/week) is the cleaner lever. You'll find the TDEE relation in the cut calculator.

Is the kcal-per-kg math exact?

No, it's a rule of thumb. ~7,700 kcal/kg is the established approximation. Real progress moves around that value.

Watch the % view carefully. 0.5 kg/week can already be 'aggressive' at 55 kg.

Classification: moderate — recommended corridor

Explained

What this calculator does for you

A weekly rate of '0.5 kg' sounds comparable — but for a 50 kg person it's twice as aggressive as for a 100 kg person. That's why we also express it as a percentage of body weight.

The calculator shows the corresponding daily calorie delta (deficit or surplus) and whether your pace sits in the conservative, moderate or aggressive range.

That honest classification matters more than the number itself: aggressive pace means more muscle loss when cutting and more fat gain when bulking.

Science

Scientific background

Energy balance: Δkcal/day = rate × 7,700 / 7. It's a deficit for loss and a surplus for gain.

Current reviews recommend losing 0.5–1.0 % of body weight/week and gaining 0.25–0.5 % (or less for advanced athletes). Faster = worse fat-to-muscle ratio.

Percentage-based pacing is fairer than absolute kilos — it scales with your starting point.

Examples

Practical examples

80 kg, lose, 0.5 kg/week

Deficit ~550 kcal/day. 0.63 %/week — in the moderate corridor.

70 kg, gain, 0.5 kg/week

Surplus ~550 kcal/day. 0.71 %/week — above the lean range, expect noticeable fat gain.

Avoid these

Common mistakes

01Comparing pace in absolute kilos instead of % body weight.
02Choosing an aggressive pace without protecting muscle (lifting, protein).
03Impatience during gain phases — lean bulks take months.

Recommendations

Further recommendations

01Stay in the moderate corridor. Safe, plannable, sustainable.
02Plan strength training and sufficient protein in parallel.
03Judge progress across 3–4 week windows.
