Understanding Weight Loss Timeline

This calculator estimates how long it will take to reach your goal weight based on the principle that 1 kilogram (2.2 pounds) of body fat contains approximately 7,700 calories.

By maintaining a consistent calorie deficit, you can predict with reasonable accuracy how long your weight loss journey will take. However, keep in mind that weight loss is rarely linear due to various factors:

  • Water retention fluctuations
  • Changes in muscle mass
  • Metabolic adaptation
  • Hormonal changes
  • Variations in activity levels

For sustainable weight loss, most experts recommend a moderate deficit that leads to losing 0.5-1 kg (1-2 lbs) per week. Faster weight loss may be harder to maintain long-term.

Choosing Your Calorie Deficit

Mild (250 calories/day)
Slow but very sustainable weight loss. Approximately 0.25 kg (0.5 lb) per week.
Moderate (500 calories/day)
Balanced approach. Approximately 0.5 kg (1 lb) per week. Recommended for most people.
Substantial (750 calories/day)
Faster results. Approximately 0.75 kg (1.5 lbs) per week. May be more challenging to maintain.
Aggressive (1000 calories/day)
Rapid weight loss. Approximately 1 kg (2 lbs) per week. Not recommended for everyone.
