How to Calculate

Understanding the link between calories and weight is key to fitness.

Pounds to Calories

Calories = Pounds × 3,500

Example: 2 lbs × 3500 = 7,000 kcal

Calories to Pounds

Pounds = Calories ÷ 3,500

Example: 1,750 kcal ÷ 3500 = 0.5 lbs

Weight Loss Science

Body fat is high-density storage for energy. 1 pound of adipose tissue (body fat) consists of approximately 87% pure fat.

  • 1 lb Fat ≈ 3,500 kcal deficit
  • Safe loss: 1-2 lbs per week
  • Muscle burns more at rest than fat
  • Hydration affects daily weight shifts
