Ruben Meerman, PhD, thought about this frequently during his own weight loss transformation. Dr. Meerman became intrigued with the biochemistry of weight loss after he lost 15 kilograms/33 pounds.
Many doctors, personal trainers, researchers, and dieticians believe that the fat you lose is converted into energy or heat in your body. However, this is far from true.
Dr. Meerman and Dr. Brown, a professor at UNSW School of Biotechnology and Biomolecular Sciences, had a paper published in the British Medical Journal that examined where fat really goes.
According to their paper, if you follow the atoms in 10 kilograms/22 pounds of fat, 8.4 of these kilograms/pounds are exhaled from carbon dioxide through your lungs. The remaining kilograms/pounds become water, which can be excreted from sweat, breath, tears, or bodily fluids.
Dr. Meerman shares his personal experience with weight loss, as well as why he decided to look into the puzzling question, 'When you lose weight, where does your fat go?"
Ruben Meerman, PhD, studied physics at the Queensland University of Technology. He graduated in 1993 and worked at Laserdyne Technologies Pty Ltd on the Gold Coast designing and manufacturing thin film, multilayer optical coatings and using physical vapour deposition (evaporative and electron beam) techniques for gas and solid state laser applications.
