Calorie Intake And Weight Loss Calculator For Women

Weight Loss Formula:

\[ \text{Daily intake} = \text{TDEE} - \text{deficit} \] \[ \text{Weight loss} = \frac{\text{deficit} \times \text{days}}{3500} \]

1. What is This Calculator For?

This calculator helps women estimate their daily calorie intake for weight loss based on their Total Daily Energy Expenditure (TDEE) and a chosen calorie deficit. It also projects expected weight loss over a specified time period.

2. How Does the Calculator Work?

The calculator uses these formulas:

\[ \text{BMR} = 655 + (4.35 \times \text{weight in lbs}) + (4.7 \times \text{height in inches}) - (4.7 \times \text{age}) \] \[ \text{TDEE} = \text{BMR} \times \text{activity factor} \] \[ \text{Daily intake} = \text{TDEE} - \text{deficit} \] \[ \text{Weight loss} = \frac{\text{deficit} \times \text{days}}{3500} \]

Where:

BMR — Basal Metabolic Rate (calories burned at rest)
TDEE — Total Daily Energy Expenditure (calories burned including activity)
3500 kcal ≈ 1 lb of body weight

3. Understanding the Results

BMR: The calories your body needs at complete rest.
TDEE: Your total daily calorie expenditure based on activity level.
Daily Intake: Recommended calories for your weight loss goal.
Weight Loss: Projected weight loss over the specified period.

4. Using the Calculator

Tips: For accurate results, measure your weight in the morning before eating. Choose an activity level that matches your typical week. A deficit of 500 kcal/day typically results in about 1 lb of weight loss per week.

5. Frequently Asked Questions (FAQ)

Q1: What's a safe calorie deficit?
A: Generally 250-1000 kcal/day deficit is safe, resulting in 0.5-2 lbs weight loss per week.

Q2: Why isn't my weight loss linear?
A: Water retention, hormonal changes, and other factors can cause fluctuations.

Q3: Should I eat back exercise calories?
A: The TDEE already accounts for your activity level - don't eat extra for exercise unless you're very active.

Q4: How often should I recalculate?
A: Recalculate every 10-15 lbs lost or if your activity level changes significantly.

Q5: Why women-specific calculation?
A: Women typically have lower BMR than men due to body composition differences.
