I'm not any kind scientist but from watching vids by Gary Taubes, Dr Lustig etc I have this idea in my head that the First Law of Thermodynamics applies to closed systems.
The human body would seem to me, to be leaky i.e. we lose heat, sweat, urine and poo. Maybe someone with more of a scientific mind can comment ?
The human body can run on carbs or ketones or both. At night, even if someone doesn't eat LCHF we can switch over to ketones while we sleep. Babies being breastfed are growing on ketones.
It's quite reasonable to say that what works for one person doesn't work for another. We have two types of genes, the hereditary ones and the environmentally- influenced ones so maybe everyone has an individual metabolic system in the same way that we have different fingerprints.
I have never counted calories and never been on a calorie controlled diet and I don't religiously count carbs either. I eat what we decide to make from the available food. Sometimes we don't feel like much, other times we'll eat more.
I tend to think that I do eat more calories though because I eat more high fat low carb low protein dairy than I used to. Just one tub of creme fraiche is 764 calories and 300ml of double cream is over 1317 calories. Yumm
Its not a closed system, so inefficiencies will exist.
I seem to be particularly efficient though, others aren't as unlucky as me, as it seems whatever energy source I use, income must be kept below my expenditure level.
I would guess the difficult bit to accept, is if you reduce your calorie intake, and further reduce it, and still never lose weight, if you extrapolate that to a zero calorie intake, or even down to an intake that would reasonably be well below that of the bodies resting energy expenditure, it would seem to suggest energy is being created.
I think, if there were people that could seem to produce energy from nothing, it would be a gene worth looking at more closely.
