Standard BMI Categories

What each calculatoractually tells you.

What it shows: Your weight relative to your height: the most common first check of an adult's weight.
How it's calculated: Weight (kg) divided by height (m) squared. WHO categories: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obesity.
Keep in mind: BMI can't tell muscle from fat. It gives a poor picture for athletes, during pregnancy, and for children and teenagers, who are measured against growth charts instead.

What it shows: The energy your body uses at complete rest, just for vital functions such as breathing and circulation.
How it's calculated: The Mifflin–St Jeor equation: 10 × weight (kg) + 6.25 × height (cm) − 5 × age, plus 5 for men or minus 161 for women.
Keep in mind: It's an estimate. Body composition (how much muscle you carry), illness and some medicines can push your real metabolism higher or lower.

What it shows: All the calories you burn in a day, including daily activity and exercise.
How it's calculated: BMR multiplied by an activity factor: 1.2 sedentary, 1.375 lightly active, 1.55 moderately active, 1.725 very active and 1.9 extremely active.
Keep in mind: How accurate this is depends above all on choosing the right activity level.

What it shows: The daily calories at which your current weight stays roughly the same.
How it's calculated: Equal to your TDEE: eat this much, and the energy you take in roughly matches what you burn.
Keep in mind: Day-to-day weight swings with water and food in the body, so judge whether it's stable by the average over a few weeks.

What it shows: A suggested daily calorie target for losing weight gradually, at the pace you choose.
How it's calculated: Your TDEE minus 250, 500 or 1,000 kcal, for roughly 0.25, 0.5 or 1 kg a week, assuming a kilogram of body fat holds about 7,700 kcal.
Keep in mind: Real weight loss is rarely a straight line, and a lighter body burns fewer calories. Large deficits are best done under a dietitian's supervision.

What it shows: A suggested daily calorie target for gaining weight gradually.
How it's calculated: Your TDEE plus 250, 500 or 1,000 kcal, for roughly 0.25, 0.5 or 1 kg a week.
Keep in mind: Whether the weight you gain is muscle or fat depends on what you eat and how you train, not just on calories.
