Weight loss often slows due to metabolic adaptation. The blue line shows what may happen if you increase your deficit later in the cut.
Weight Loss Calculator
This weight loss calculator estimates how long it will take to reach your target body fat based on your calorie deficit, body weight, and training frequency. Enter your current stats above to generate a personalised fat-loss forecast and timeline.
How does the calculator work?
Fat loss occurs when you consistently maintain a calorie deficit. Roughly 7700 calories correspond to one kilogram of body fat. This calculator estimates your maintenance calories, predicts your weekly weight loss, and generates a realistic timeline to reach your goal.
How fast can you lose weight safely?
Most people can safely lose around 0.5–1% of their body weight per week. Faster weight loss can increase the risk of muscle loss and metabolic slowdown. A moderate calorie deficit combined with resistance training usually produces the best long-term results.
Is this weight loss calculator accurate?
This calculator provides an estimate based on metabolic formulas and typical fat-loss patterns. Real results may vary depending on diet adherence, sleep, stress, and training intensity.
