A safe calorie deficit is one you can maintain long enough to reach your goal, without compromising health, performance, or daily life.
Rules of thumb
- Aim for 0.5–1% of body weight lost per week.
- Keep protein high — typically 1.6–2.2 g per kg of body weight.
- Strength train at least twice a week to preserve muscle.
- Sleep 7–9 hours.
- Plan diet breaks every 8–12 weeks if cutting for a long stretch.
