Time To Target Formula:
From: | To: |
The Time To Target calculator estimates how long it will take to reach your weight goal based on your current weight, target weight, and daily calorie deficit.
The calculator uses the following equation:
Where:
Explanation: The equation calculates how many days it will take to lose the weight difference at your specified daily calorie deficit.
Details: A calorie deficit occurs when you consume fewer calories than you burn. This is the fundamental requirement for weight loss. The calculator helps you plan realistic timelines for your weight loss goals.
Tips: Enter your current weight and goal weight in pounds, and your planned daily calorie deficit. All values must be positive numbers.
Q1: Why 3500 calories per pound?
A: This is the commonly accepted estimate that one pound of body fat contains approximately 3500 calories of energy.
Q2: Is the calculation always accurate?
A: It provides an estimate. Actual results may vary due to metabolic adaptations, water weight fluctuations, and changes in body composition.
Q3: What's a safe calorie deficit?
A: Generally 500-1000 calories per day for 1-2 lbs weight loss per week. Extreme deficits can be unhealthy and counterproductive.
Q4: Should I recalculate as I lose weight?
A: Yes, as your weight changes, your maintenance calories will change, potentially affecting your actual deficit.
Q5: Does this account for plateaus?
A: No, the calculation assumes linear progress. Most people experience plateaus due to metabolic adaptation.
