1. What is the 1lb a Week Weight Loss Formula?

The "Lose 1lb a Week" formula calculates the daily calorie intake needed to achieve a weight loss of approximately 1 pound per week, based on your Total Daily Energy Expenditure (TDEE).

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( \text{TDEE} \) — Total Daily Energy Expenditure (kcal/day)
• \( 3500 \) — Calories in 1 pound of body fat
• \( 7 \) — Days in a week

Explanation: To lose 1 pound per week, you need a daily deficit of 500 calories (3500 calories ÷ 7 days).

3. Importance of Calorie Deficit

Details: Creating a consistent calorie deficit is the most scientifically validated approach to weight loss. This calculator helps establish a moderate, sustainable deficit for healthy weight loss.

4. Using the Calculator

Tips: Enter your TDEE in kcal/day. For accurate results, use a recent TDEE calculation that accounts for your activity level. The result shows your recommended daily calorie intake for 1lb/week weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Is 1lb/week a safe weight loss rate?
A: Yes, 1-2 pounds per week is generally considered a safe and sustainable rate of weight loss.

Q2: What if I want to lose weight faster?
A: You can increase the deficit, but don't go below 1200 kcal/day for women or 1500 kcal/day for men without medical supervision.

Q3: Why 3500 calories per pound?
A: This is the estimated energy contained in 1 pound of body fat, though individual variations exist.

Q4: Should I adjust my intake as I lose weight?
A: Yes, as you lose weight your TDEE decreases, so you should recalculate periodically.

Q5: What about macronutrients?
A: While calorie deficit determines weight loss, proper macronutrient balance is important for health and satiety.
