If by liberal, you mean free, then I am liberal. The word is derived from the Latin 'liberos', meaning 'freed slave' [noun] or the mere act of 'freeing' someone. I am free from all political constraints (or otherwise).

However, I'm in excellent shape, do not eat McDonald's at all, and I work (A LOT). So I don't understand how or why you reasonably (key word) characterize all liberals thusly. You understand your claim contains mere pathos - no logos and lacking all ethos.
