There may be a relationship between people who become addicted to caffeine in coffee and other hot drinks because they are really experiencing the body heat from those who consume higher levels of fat. This would include most all people in colder climates. People living in warmer climates need not consume high levels of fat.
If we are experiencing history connected with the Little Ice Age or history from those people who live in colder climates we may be eating higher levels of fat because they are directed to do so and this may be harming our bodies.
The other thing I wanted to mention is that higher body temperatures do produce heat shock proteins which will cause chaperones to kick in and unfold proteins. This will cause one to appear bloated or mushy as I refer to it if this goes on too long. In warmer temperatures consuming lots of cold fluids such as water, is important. Glycerol itself can lower the body temperature without increasing fatty acid storage. I’m not sure about raising blood pressure with natural glycerol from fats.
