Question

Water? Idk

In: 0

Answer 1

Human body is 70% water (irc and for sake of argument)

Example: you eat 1 kg of extra food, your body use it to make muscles&fat. It’s practically building a 1kg of water container. Hence that’s 4kg extra weight once you factor the water that fills it.

You need to burn your intake to preserve weight. If you eat more than you burn your body goes in “container building mode”
