Calculate Ideal Weight
What is Ideal Weight?
Ideal weight is an estimate of healthy body weight based on height and gender. Three main formulas are used: Devine (1974), Robinson (1983), and Miller (1983). Each uses different equations, so the average provides a more realistic range. These formulas were developed for drug dosing but are widely used in nutrition.
When to use Ideal Weight?
Use to set weight goals in nutrition plans, calculate caloric needs, adjust medication doses (especially in obese patients), and guide patients. Does not replace complete body composition assessment. Athletes and people with high muscle mass may have healthy weight above 'ideal'.
Limitations and Considerations
Does not consider body composition, muscle mass, bone structure, or fat distribution. Athletes, elderly, amputees, and children require differentiated assessment. Use together with BMI, waist circumference, body fat percentage, and complete clinical evaluation. Formulas were developed in specific populations (mainly Caucasian).
Frequently Asked Questions about Ideal Weight
Why do the three formulas give different results?
Each formula was developed in different populations and contexts. Devine (1974) was created for drug dosing, Robinson (1983) and Miller (1983) refined the equation. Differences reflect variations in studied samples. Therefore, the average of the three is more reliable than any one alone.
Should athletes use ideal weight?
With caution. Athletes, especially strength athletes, have above-average muscle mass, which increases weight without being fat. For them, body composition (body fat percentage, lean mass) is more important than absolute weight. Use bioimpedance, DEXA, or skinfold measurements.
Is ideal weight the same as healthy weight?
Not necessarily. Healthy weight is a broader range that considers body composition, fat distribution, metabolic health, and overall well-being. A person can be above 'ideal weight' and be metabolically healthy, or at 'ideal weight' and have sarcopenic obesity.
How to use ideal weight in diets?
Use as initial reference to calculate caloric needs (BMR, TDEE). If patient is far above ideal weight, use an intermediate weight (adjusted weight) to avoid underestimating calories. Monitor progress by body composition, not just scale weight.
