They have found that some obese people have certain bacteria in their intestines that enables them to consume extra calories from things like
cellulose which normally do not contribute to human energy requirements. It is pretty rare, but in some extreme instances, this can lead a person to
be obese even when they only eat a normal amount of calories. Ultimately, energy consumption is based upon the production of ATP in the cells, so you
should be able to estimate how much a person is producing in ATP based upon the amount of oxygen they are consuming. If you could somehow measure the
level of CO2 in a person's exhalations throughout the course of a day, it should give you a spot on estimate of the number of calories they are
burning. If this number is higher than the number of calories they are consuming, then they should lose weight because the ultimate product of the
breaking down of sugars, starches, fats, cholesterol and protein is CO2 and if CO2 builds up in your system, you will perish.
