Worked Calculation Example
A 30-year-old female weighing 65 kg (143.3 lbs) at 168 cm (5 ft 6 in) with moderate physical activity (exercise 3 to 5 sessions per week) calculating baseline daily expenditure and a 500 kcal deficit for gradual weight loss.
Mifflin-St Jeor Basal Metabolic Rate (BMR) = (10 × 65) + (6.25 × 168) - (5 × 30) - 161 = 650 + 1,050 - 150 - 161 = 1,389 kcal/day. Moderate physical activity multiplier = 1.55. Total Daily Energy Expenditure (TDEE) = 1,389 × 1.55 = 2,153 kcal/day. Applying a standard 500 kcal daily deficit yields an intake target of 1,653 kcal/day (~1,650 kcal/day) to support approximately 0.45 kg (~1 lb) of fat reduction per week.
The client maintains an intake target of 1,650 kcal/day, creating a controlled deficit that encourages fat mobilization while preserving metabolic rate and lean mass.
Frequently Asked Questions
Which formula does the embedded calorie calculator use?
The widget uses the clinically validated Mifflin-St Jeor equation to estimate Basal Metabolic Rate (BMR), followed by standard physical activity multipliers (1.2 to 1.9) to compute Total Daily Energy Expenditure (TDEE).
Can I adjust the default height of the embed iframe?
Yes. Use the height slider in the generator panel or modify the height attribute in the copied iframe tag (recommended between 520px and 680px depending on layout padding).
Does the calculator diagnose nutritional deficiencies or metabolic disease?
No. Caloric recommendations are statistical approximations based on standardized population equations. They do not diagnose metabolic conditions or substitute for personalized medical nutrition therapy.
