Guide & Explanations
Expert Weight Loss Calculator: Plan Your Transformation
Weight loss is not just about willpower; it's about biological mathematics. Our calculator uses the most accurate formulas (Mifflin-St Jeor and Katch-McArdle) to provide a clear and realistic roadmap to your ideal weight.
How the calculation works
To lose weight, you must create a calorie deficit. Our tool first calculates your TDEE (Total Daily Energy Expenditure), which is the number of calories you burn each day based on your basal metabolic rate and activity level.
The pillars of your plan:
- Personalized Calorie Deficit: Based on your chosen pace (from 0.5lb to 2lbs per week), we calculate exactly how many calories you should consume.
- Macros Breakdown: Protein, Carbs, and Fats are adjusted according to your diet type (Ketogenic, High Protein, etc.) to help preserve muscle mass.
- Visual Projection: Visualize your weight curve over the coming months to stay motivated.
Safety First
Our calculator includes health alerts. If your goal requires a calorie intake below 1200 kcal (Women) or 1500 kcal (Men), a warning will appear. Losing weight too quickly can be counterproductive and harm your metabolism in the long run. Aim for a loss of 1 to 2 lbs per week for sustainable results.

Q: What is the recommended weekly weight loss?
R: For healthy and sustainable weight loss, it is generally recommended to aim for 1 to 2 lbs (0.5 to 1 kg) per week. Faster loss can lead to excessive muscle wasting and nutritional deficiencies.
Q: How many calories should I cut to lose weight?
R: It is estimated that a cumulative deficit of 3,500 calories is required to lose about 1 lb of fat. A daily deficit of 500 calories theoretically leads to a loss of 1 lb per week.
Q: Why has my weight loss stalled?
R: Metabolism adapts as you lose weight (you burn fewer calories because you weigh less). It may be necessary to re-evaluate your calorie needs or increase your physical activity.
