Fun fact I came upon this week while reading a book unrelated to weight loss.
The origin of the abbreviation 'lb.' for pound comes from the Latin words 'libra pondo', which is the word for balancing scales, and pounds weight. We however just use the abbreviation 'lb.' for libra and don't have an abbreviation for pound.
Libra is also a word that is both singular and plural, so adding a 's' to the end, such as 'lbs.' is incorrect... It is still just lb... whether we lose 1 lb., or 4 lb.
I'm a nerd so this is fun information.
