Where does melted fat go when you lose weight? The surprising scientific answer
- •Research shows that about 84 percent of lost body fat is exhaled as carbon dioxide through the lungs.
- •The remaining 16 percent of fat turns into water and leaves the body through sweat, urine, and other fluids.
- •Excess energy from food is stored in fat cells as triglycerides, either beneath the skin or around internal organs.
- •Weight loss requires burning more energy than consumed, triggering the breakdown of stored fat through lipolysis.
- •Breathing faster does not cause weight loss; sustainable fat reduction depends on diet, exercise, and calorie management.
Key Questions Answered
