Frequently asked questions
- How do I calculate my BMI?
- BMI (Body Mass Index) is calculated by dividing your weight in kilograms by height in meters squared. Our BMI Calculator handles the conversion from pounds and inches, and shows where you fall on the BMI scale with health recommendations.
- How many calories do I need per day?
- Daily calorie needs depend on age, sex, weight, height, and activity level. Our Calorie Calculator uses the Mifflin-St Jeor equation to estimate your basal metabolic rate (BMR) and total daily energy expenditure (TDEE).
- What is a healthy body fat percentage?
- Healthy body fat ranges are 10-20% for men and 18-28% for women. Use our Body Fat Calculator to estimate your body fat percentage using measurements like waist, neck, and hip circumference.
- How do I calculate my ideal weight?
- Ideal weight depends on height, body frame, and sex. Our Ideal Weight Calculator uses multiple formulas (Devine, Robinson, Miller, Hamwi) to give you a healthy weight range based on your measurements.
- How much water should I drink daily?
- General guidelines suggest 8 cups (64 oz) daily, but needs vary by weight, activity, and climate. Our Water Intake Calculator provides personalized recommendations based on your body weight and activity level.
- What is BMR and how is it calculated?
- BMR (Basal Metabolic Rate) is the calories your body burns at rest. It is calculated using weight, height, age, and sex. Our Calorie Calculator computes BMR and multiplies by activity factors to estimate total daily needs.
- How do I track macros for weight loss?
- Macros (protein, carbs, fat) should be balanced for your goals. A common starting point is 40% carbs, 30% protein, 30% fat. Our Macro Calculator helps you determine optimal macro ratios and daily gram targets.
- What is a healthy resting heart rate?
- A normal resting heart rate for adults is 60-100 beats per minute. Athletes may have rates as low as 40 bpm. Lower resting heart rates generally indicate better cardiovascular fitness.
