"that the body was "too complex" to be governed by mere physics." The body is too complex to be governed by "mere physics", because it uses control systems that regulate the intake process. I can eat three times more than a friend of mine, and incorporate to my body way less than my friend, because bacteria and virus in my intestines are completely different from hers. Also my body is different. A calorie of fat has nothing to do with a calorie of sucrose or glucose. "Mere physics" of burning something at 1000C and measuring the thermal output is completely different from the "real physics"of metabolizing substances in a 20 different steps chain process, where every step could be inhibited or excited by cell control systems.

As I say elsewhere, all this is by the by; all that matters is net calorie balance and all that's needed is to compare inputs (diet, exercise) with outputs (weight, appearance). Your friend no more needs to know about your gut flora than you need to know about my insulin sensitivity.

I doubt that you can eat three times more than your friend. In fact, that is impossible. Please provide us with some real numbers and data.

  If I may generalise most offensively, people in prosperous societies have basically no freaking idea how much they are eating (or not eating, as the case may be). Eg: http://www.ncbi.nlm.nih.gov/pubmed/7869932 http://www.ncbi.nlm.nih.gov/pubmed/7869932 http://www.ncbi.nlm.nih.gov/pubmed/2082216 http://www.ncbi.nlm.nih.gov/pubmed/2082216 I remember talking to a (rake-thin) cousin of mine about this when we went to dinner one night. "I eat as much as anyone", he protested. Later in the evening, noticed that while I had finished the chips that came with our dinners, he had not.
