MyPlate.food nutrition tools

Compute Body Mass Index and its weight classification from height and weight alone. Adults use the WHO cutoffs (underweight / normal / overweight / obese); for ages 2–19 pass age + sex and it uses the CDC BMI-for-age percentiles instead. Returns a canonical myplate.food URL and source citation.

Estimate body-fat % using the U.S. Navy circumference method, with a Deurenberg BMI-based cross-check and ACE category. Needs sex, age, height, weight and tape measurements of neck and waist (plus hip for women).

Run one of myplate.food's quick body-composition & fitness calculators and get its value plus the healthy band. Pick `metric` and pass that metric's fields: • waist-to-height — waist, height • waist-to-hip — waist, hip, sex • lean-body-mass — weight, height, sex • ffmi — weight, height, body_fat, se

Estimate daily calorie needs (IOM Estimated Energy Requirement) and return the USDA MyPlate food-group plan at that level — cups of fruit/vegetables/dairy, ounce-equivalents of grains/protein, plus weekly vegetable & protein subgroup targets and BMI. From age, sex, height, weight and activity (pregn

Use this when you want the whole energy picture in one call. Returns resting metabolic rate (Mifflin-St Jeor) and revised Harris-Benedict, total daily energy expenditure (TDEE) at every activity level, three weight-loss deficit tiers, macronutrient splits, protein targets and healthy-weight ranges.

Compute basal/resting metabolic rate — the calories your body burns at rest. Returns the headline Mifflin-St Jeor (1990) value plus the revised Harris-Benedict (Roza & Shizgal 1984) estimate for comparison. Needs age, sex, height and weight.

Use this when you need maintenance calories — the total daily energy expenditure. Mifflin-St Jeor resting metabolic rate scaled by a physical-activity multiplier; returns the TDEE at the given activity level plus a table across all four levels (sedentary → very-active). Needs age, sex, height, weigh

Use this when someone wants a weight-loss calorie target. Returns maintenance calories (TDEE) and three deficit tiers — mild (−250), standard (−500) and aggressive (−750 kcal/day) — each with the realistic weekly rate it buys, and a flag when a target dips below BMR. Needs age, sex, height, weight a

Split a daily calorie budget into protein, carbohydrate and fat grams across three presets (balanced, higher-protein, lower-carb), within the IOM acceptable macronutrient distribution ranges (protein 10–35%, carbs 45–65%, fat 20–35%). Pass `calories` directly, or a body profile (age, sex, height, we

Daily protein target in grams from body weight and activity level: the IOM RDA floor (0.8 g/kg) and an activity-scaled range up to the Academy of Nutrition and Dietetics / Dietitians of Canada / ACSM (2016) 1.2–2.0 g/kg athlete range. Needs age, sex, height, weight and activity.

Estimate ideal body weight from height and sex via four classic clinical formulas (Devine 1974, Robinson 1983, Miller 1983, Hamwi 1964), plus the healthy-BMI (18.5–24.9) weight band and current BMI for context. Needs age, sex, height, weight.

Protein target to preserve muscle during weight loss on a GLP-1 medication (Ozempic, Wegovy, Zepbound, Mounjaro): the 1.2–1.6 g/kg preservation range vs the 0.8 g/kg IOM RDA, a per-meal spread, and the DRI fiber Adequate Intake for age + sex. Needs weight, age and sex.

Daily energy requirement for the German/Austrian/Swiss (D-A-CH) DGE framework: resting energy via the Müller et al. (2004) equation the DGE uses, scaled by a PAL activity factor. Returns resting energy, the requirement at the chosen PAL, and a table at PAL 1.4 / 1.6 / 1.8. Needs sex, age and weight.

Return the full Dietary Reference Intakes table for a life stage — recommended intakes and tolerable upper limits for macronutrients, vitamins and minerals (IOM 2005/2006/2011, NASEM 2019), plus the Estimated Energy Requirement and BMI. Needs age, sex, height, weight (pregnancy/lactation optional; e
