What “authority source” means
A source supports the equation, threshold, nutrient reference, or safety context. It does not turn a planning calculator into medical advice. LeanMetric labels custom behavior scores and convenience splits as planning heuristics, and labels search-intent variants as scenario adaptations.

| Workout Schedule Calculator Volume alone does not describe intensity, recovery, or exercise quality. | LM-WORKOUT-VOLUME-01 | Training days per week, Duration | Weekly training time = sessions per week x minutes per session. | Independent equation | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Zone 2 Cardio Calculator Medication, pregnancy, cardiovascular disease, and heat can change an appropriate range. | LM-HEARTRATE-TANAKA-01 | Age, Duration | Estimated maximum heart rate = 208 - 0.7 x age; planning range = 60-70% of estimated maximum. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| HIIT Calorie Calculator Adult planning estimate; terrain, technique, fitness, and devices vary. | LM-ACTIVITY-MET-01 | Current weight, Duration, Intensity | Calories = MET x 3.5 x body weight (kg) / 200 x minutes. Each activity has distinct Compendium-based intensity presets. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Swimming Calories Calculator Adult planning estimate; terrain, technique, fitness, and devices vary. | LM-ACTIVITY-MET-01 | Current weight, Duration, Intensity | Calories = MET x 3.5 x body weight (kg) / 200 x minutes. Each activity has distinct Compendium-based intensity presets. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Elliptical Calories Calculator Adult planning estimate; terrain, technique, fitness, and devices vary. | LM-ACTIVITY-MET-01 | Current weight, Duration, Intensity | Calories = MET x 3.5 x body weight (kg) / 200 x minutes. Each activity has distinct Compendium-based intensity presets. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Stairmaster Calories Calculator Adult planning estimate; terrain, technique, fitness, and devices vary. | LM-ACTIVITY-MET-01 | Current weight, Duration, Intensity | Calories = MET x 3.5 x body weight (kg) / 200 x minutes. Each activity has distinct Compendium-based intensity presets. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Daily Deficit to Weight Loss Calculator Educational linear estimate only; real long-term loss slows. | LM-ENERGY-CONVERT-01 | Daily calorie deficit | Weekly kg estimate = daily kcal deficit x 7 / 7,700; monthly and annual views multiply the weekly estimate. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Monthly Weight Loss Calculator Educational linear estimate only; real long-term loss slows. | LM-ENERGY-CONVERT-01 | Daily calorie deficit | Weekly kg estimate = daily kcal deficit x 7 / 7,700; monthly and annual views multiply the weekly estimate. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Yearly Weight Loss Calculator Educational linear estimate only; real long-term loss slows. | LM-ENERGY-CONVERT-01 | Daily calorie deficit | Weekly kg estimate = daily kcal deficit x 7 / 7,700; monthly and annual views multiply the weekly estimate. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Recipe Calories per Serving Calculator Accuracy depends on complete ingredients and consistent finished portions. | LM-RECIPE-SERVING-01 | Recipe total calories, Servings | Calories per serving = complete recipe calories / number of equal servings. | Independent equation | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Calorie Density Calculator Compare foods in the same cooked/raw state as their nutrition data. | LM-FOOD-DENSITY-01 | Calories in the food amount, Food weight | Energy density = total calories / food weight (g) x 100; kJ/100 g is also displayed. | Independent equation | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Protein Cost Calculator Use one currency and comparable edible portions; price is not a nutrition-quality score. | LM-PROTEIN-COST-01 | Food cost in your currency, Protein | Cost per 25 g protein = item cost / protein grams x 25. | Independent equation | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Step Goal Progression Calculator No universal 10,000-step requirement; pain and recovery take priority. | LM-STEPS-PROGRESSION-01 | Current daily steps, Tracking period | Target = current daily baseline + 500 steps per week, capped at 15,000 steps/day. | Planning heuristic | Automated: formula dispatch, input presence, Metric/US units, render, canonical | |
| Weight Maintenance Range Calculator Non-pregnant adults; activity factors are planning estimates. | LM-ENERGY-TDEE-01 | Current weight, Height, Age, Sex used by the formula, Activity level | BMR uses Mifflin-St Jeor; estimated maintenance = BMR x selected activity factor. A +/-100 kcal range reflects normal estimation uncertainty. | Shared evidence model | Automated: formula dispatch, input presence, Metric/US units, render, canonical |
