Time to Target Weight Formula:
From: | To: |
The Time to Target Weight Calculator estimates how long it will take to reach your goal weight based on your current calorie deficit or surplus. It uses the principle that 1 pound of body weight equals approximately 3500 calories.
The calculator uses the following equation:
Where:
Explanation: The equation calculates how many days it will take to reach your goal weight based on your current calorie deficit (when TDEE > Intake) or surplus (when Intake > TDEE).
Details: Knowing the estimated time to reach your goal helps with setting realistic expectations and maintaining motivation during weight loss or gain journeys.
Tips: For accurate results, use precise measurements of your weight and honest estimates of your TDEE and calorie intake. Remember that weight loss isn't always linear.
Q1: Why 3500 calories per pound?
A: This is a widely accepted estimate that 1 pound of body fat contains approximately 3500 calories of energy.
Q2: How accurate is this calculation?
A: It provides a rough estimate. Actual results may vary due to metabolic adaptation, water retention, and other factors.
Q3: What if my TDEE changes during my weight loss?
A: As you lose weight, your TDEE typically decreases. For long-term projections, you may need to recalculate periodically.
Q4: Can I use this for weight gain?
A: Yes, the same principle applies - just enter a goal weight higher than your current weight.
Q5: What's a healthy rate of weight loss?
A: Generally 1-2 pounds per week is considered safe and sustainable for most people.
