Calorie Needs Calculator – Weight Loss calculator inputs, explained

Each control below is a real variable in target kcal ≈ Mifflin-St Jeor BMR × activity, then a goal offset. If a unit is already printed, do not convert it again. The sample is a walkthrough, not a clinical target.

Sex

Sex switches the constant in Mifflin-St Jeor and similar equations. It is not a gender-identity questionnaire. The sample uses male. Overwrite it when your chart or scale does not look like the demo.

Age

Age is whole years for these adult formulas. Pediatric BMI uses a different CDC chart this page does not implement. The sample uses 30 years. Overwrite it when your chart or scale does not look like the demo.

Height

Height must match the unit on the label. Mixing cm and inches is the usual way BMI and BSA go off by a factor of two. The sample uses 170 cm. Overwrite it when your chart or scale does not look like the demo.

Weight

Weight is a scale weight, not a goal weight, unless the label says otherwise. The sample uses 70 kg. Overwrite it when your chart or scale does not look like the demo.

Activity factor

Activity factor is a multiplier, not a GPS track. 1.2 is sedentary; 1.55 is moderate. Inflating it is how TDEE looks like a buffet pass. The sample uses 1.55. Overwrite it when your chart or scale does not look like the demo.

How to calculate calorie needs calculator – weight loss (the formula)

On the Calorie Needs Calculator – Weight Loss, the engine applies target kcal ≈ Mifflin-St Jeor BMR × activity, then a goal offset to sex, age, height, weight. The slug is calorie-needs-calculator-weight-loss.

A 500 kcal deficit is a planning sketch. Rapid loss, pregnancy, eating disorders, and medical diets need a clinician, not this slider.

Two honest ways to break this formula: mix metric and imperial, or treat a percent as a decimal. Recalculate after you fix the unit. If the headline still looks absurd, this may be the wrong tool.

Who should use this Calorie Needs Calculator – Weight Loss calculator

This page is written for people setting a maintenance, loss, or gain calorie target who need a calorie needs calculator – weight loss number they can audit.

Run the sample, then your chart numbers. If both headlines look reasonable, you probably have the right identity.

Change only one field when you compare two days or two lab draws. Changing three things at once hides which input moved the result.
