The correct spelling of lean + ness is <em>leanness</em>.
The suffix -ness is used to transform an adjective into a noun. It indicates a quality of something. In this case, the quality of being lean, not having much body fat:
<em>For baby's first foods it's important to check the </em><em>leanness</em><em> of the meat we give them.</em>
When adding the suffix -ness to the root word "lean", we keep its last N. There is no change in the spelling. In this way, <em>leannes</em>s is spelled with double N.
If the adjective is a two-syllable word ending in Y, when adding the suffix -ness we must change the Y for an I:
- happy: happiness
- lonely: loneliness
