Calorie Calculator To Lose Weight UK Pounds

Calorie Equation:

\[ Calories = (10 \times (weight_{lb} \times 0.4536) + 6.25 \times (height_{in} \times 2.54) - 5 \times age + gender_{factor}) \times activity_{factor} - 500 \]

1. What Is This Calorie Calculator?

This calculator estimates your daily calorie needs for weight loss based on the Mifflin-St Jeor equation, adjusted for UK measurements (pounds and inches) and including a 500 kcal deficit for weight loss.

2. How Does The Calculator Work?

The calculator uses the following equation:

\[ Calories = (10 \times (weight_{lb} \times 0.4536) + 6.25 \times (height_{in} \times 2.54) - 5 \times age + gender_{factor}) \times activity_{factor} - 500 \]

Where:

\( weight_{lb} \) — Weight in pounds
\( height_{in} \) — Height in inches
\( age \) — Age in years
\( gender_{factor} \) — 5 for men, -161 for women
\( activity_{factor} \) — Multiplier based on activity level

Explanation: The equation calculates your Basal Metabolic Rate (BMR), adjusts for activity level, then subtracts 500 kcal to create a weight loss deficit.

3. Importance Of Calorie Calculation

Details: Accurate calorie estimation is crucial for safe and effective weight loss. A 500 kcal daily deficit typically leads to about 1 lb (0.45 kg) of weight loss per week.

4. Using The Calculator

Tips: Enter your weight in pounds, height in inches, age in years, select gender and activity level. For best results, weigh yourself in the morning before eating.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500 kcal daily deficit creates about 1 lb/week weight loss, which is a safe and sustainable rate.

Q2: What if I want to lose weight faster?
A: We don't recommend deficits larger than 1000 kcal/day without medical supervision as this can lead to muscle loss and nutritional deficiencies.

Q3: How accurate is this calculator?
A: It provides a good estimate but individual variations exist. Adjust based on your actual weight loss results.

Q4: Should I eat back exercise calories?
A: The activity factor already accounts for exercise. Don't eat back calories burned through additional exercise if you want to maintain the deficit.

Q5: When should I recalculate my needs?
A: Recalculate every 10-15 lbs lost, as your calorie needs decrease with weight loss.
