When we don’t know something we tend to assume it must resemble something we experience – empirical evidence. This led Aristotle to give a faulty law of motion which Newton corrected when he found new evidence and Einstein, in turn, made some more adjustments.
Some time ago we though it was calories in, calories out because energy is conserved. While energy is conserved, the body reacts differently to different foods and even to when they are ingested. Many popular diets cut a substantial amount of weight in a short time and then fizzle out and the weight comes back. Often this is dismissed as a short term loss of water. Humans don’t have water tanks so where do we store the extra water? In fat!
Fats and oils are organic compounds that, like carbohydrates, are composed of the elements carbon (C), hydrogen (H), and oxygen (O), arranged to form molecules.

FAT = x CO2 + y H2O + other stuff
I don’t know the details but a recent article I read commented that camels can drink up to 100 liters of water at a time and store it in the hump (dromedaries) or humps (camels) on their backs in the form of fat. Bears don’t store fat for the water but for the energy to last out the Winter as do other mammals for other times of scarcity. Fat, a multipurpose warehouse for life.
I go for long walks in Portugal, my favorite way to do tourism. I take along a small bottle of water (33cc) and most of the time I barely use it, mostly just to wet my mouth. During the walk I seldom have more than a coupe of beers (70cc). I sweat a lot and urinate during the walk. Where is all that water coming from? The only other source is fat.
Sweating is a human adaptation…
Sweating helped our ancestors hunt on the African savannah. Since most mammals don’t sweat (dogs pant) they cannot sustain long distance running, they need to rest. By chasing them for hours these animals become easy prey for human hunters with longer endurance.
Based on the above I concluded that if we exercise long enough, several hours a day, then exercise does lead to fat loss and weight loss. Of course, exercising several hours a day is not practical for most modern humans unless it’s part of their job.
Another discovery was that during these walks I don’t get hungry. After a breakfast between 7 to 8 am I tend not to eat until very late in the afternoon or early evening on days when I walk. On non walk days I get hungry as usual. The body also uses the fat to generate glucose to power the walks and with sufficient blood glucose the body does not feel hungry.
Isn’t fat (the right kind and amount of fat) wonderful?

Spooky action at a distance
Einstein showed that gravity was not a direct attractive force between masses as Newton proposed but the curvature of space-time induced by mass. With billions of galaxies, stars, and other massive and minute bits and pieces space must have a truly complex and evolving curvature. No wonder there is no solution to the three body problem…
Surely gravity IS spooky action at a distance and it has little or nothing to do with rolling dice, just chaos theory.
