When a person loses weight, have you ever wondered where it goes?
This information came from the IDEA fitness journal this month –
a report featured in British Medical Journal featured a survey of 50 family doctors, dieticians and personal trainers, who were asked what they thought happened to fat once it had been ‘burned’. Most respondents believed that fat converts to energy or heat. Others thought fat becomes muscle or is eliminated from the body in faeces. According to scientists at the University of New South Wales in Australia, who have developed a formula to explain the process, fat mostly converts to carbon dioxide and exits the body in our breath. The remaining portion becomes water and leaves the body in the form of sweat, tears, urine and other bodily fluids. “Losing weight requires unlocking the carbon stored in fat cells” say the study authors.
Does that mean that the more fat we collectively lose, the more we are contributing to global greenhouse gases?
Perhaps we should all plant a tree for every kilogram of fat lost?
