Calorie Deficit: 5 Mistakes to Avoid
Sets a daily calorie target for steady weight loss. The maths is not complicated, but a handful of errors come up again and again in this and related health & fitness calculations. Here is what to watch for.
Singapore's tropical climate means you lose more fluid through sweat, even when you are not exercising. Thirst, urine colour and how you feel are good guides, and needs rise during outdoor activity or heat waves.
Programmes such as the National Steps Challenge and the Healthy 365 app have made tracking activity common. Turning those numbers into distance, pace or calories helps set realistic goals for events like IPPT or a 10 km run.
1. Mixing units
Entering pounds or inches into a metric formula gives nonsense results.
2. Measuring inconsistently
Tape measurements change with posture and breathing; measure the same way each time.
3. Cutting calories too aggressively
Very large deficits are hard to sustain and can lead to muscle loss.
4. Relying on a single measurement
Weight and heart rate fluctuate daily; trends tell you more.
5. Treating estimates as exact
Formulas such as BMR or body fat are population estimates with real margins of error.
The correct method
1 kg of fat ≈ 7,700 kcal; daily deficit = weekly loss × 7,700 ÷ 7.
For example, with these inputs:
- Your TDEE (kcal): 2,200
- Target weight loss per week (kg): 0.5
the calculator returns:
- Daily calorie target: 1,650 kcal
- Daily deficit: 550 kcal
