A thread on Gab provided these pictures. They certainly made me think! Click either image for a larger view.
The sheer volume of fat, compared to the same weight of muscle, illustrates why it's so hard to shed fat. Also, one now understands why one's weight seems to remain stable when exercising, rather than dropping. One is replacing fat mass with muscle mass, so that even as one loses inches, one's muscles weigh more through being better developed.
Not pretty images, but they certainly explain a lot!
