Lean? I’d rather be Healthy!

I was talking to a friend the other day about Lean and Six Sigma and all that – and I felt I did not know the word “lean” – so I looked it up on synonym.com and this is what I found for the adjective:

Synonyms (Grouped by Similarity of Meaning) of adj lean

And this got me thinking….How is it that we ascribe so many negative connotations to a single idea – anorexic, anorecticbony, cadaverous, emaciated, gaunt, haggard, pinched, skeletal, wasteddeep-eyed, hollow-eyed, sunken-eyedgangling, gangly, unprofitable……etc. etc.
Isn’t it time for a new word to describe what is, essentially, keeping an organisation healthy?  All better ideas for words and terms gratefully received!
