Advanced Ideal Body Weight & Health Analysis
This professional-grade health analysis tool goes beyond simple weight calculations. It integrates multiple clinical formulas used by nutritionists, physicians, and fitness professionals to provide a holistic view of your body composition and metabolic needs.
What is Adjusted Body Weight (AjBW)?
Adjusted Body Weight is a metric used primarily in clinical settings for individuals who are significantly overweight. Standard Ideal Body Weight formulas can underestimate the nutritional and medication needs of obese patients, while Actual Body Weight can overestimate them. AjBW provides a balanced middle ground for safer clinical interventions.
The Importance of Lean Body Mass (LBM)
Your Lean Body Mass represents everything in your body that isn’t fat—muscles, bones, organs, and water. Knowing your LBM is crucial for athletes and those on weight loss journeys, as it helps ensure that weight loss comes from fat stores rather than vital muscle tissue.
Understanding BMR vs. TDEE
Basal Metabolic Rate (BMR) is the number of calories your body burns at rest just to keep your organs functioning. Total Daily Energy Expenditure (TDEE) accounts for your BMR plus your physical activity. Understanding these numbers is the foundation of any successful weight management plan.
Why Waist-to-Height Ratio Matters
Recent research suggests that the Waist-to-Height Ratio (WHtR) is a more accurate predictor of cardiovascular risk than BMI. A healthy ratio is generally considered to be under 0.5, meaning your waist circumference should be less than half your height.
