Determine exact body fat loss or gain equivalent for any caloric deficit or surplus.
Human adipose tissue (stored body fat) is not 100% pure lipid. It consists of approximately 87% triglyceride fat, alongside cellular water, connective protein structures, and minerals. Because pure fat provides 9 calories per gram (4,082 kcal/lb), the energy density of human adipose tissue is calculated as:
453.59237 g/lb × 87% lipid × 9 kcal/g ≈ 3,500 kcal/lb
