Gourmet comes from Old French grommes “valet” (1352) of disputed origin. It either comes from the English grom¹ “young boy” (1225) and later “valet“(1297) (hence groom), or from gourm “gorge”, but lexicographer Alain Rey does not believe in the latter.

In the Middle Ages a gourmet was a valet in charge of wine transportation. It then (1458) evolved into a wine connoisseur and later (18th century) into a food connoisseur.

So, no sign of food in the etymology of gourmet.

¹ Of uncertain etymology. The OED says it could come from Old English groma, related to “grow”, or from Old French gromet !

Gourmet comes from Old French grommes “valet”.

But “Gourmand” means “he likes to eat” and especially “he likes to eat a lot”

“Gourmet” means “he likes to eat” and especially “he likes to eats fine dining, and searchs delicacy and refinement”, but this evolution comes from an influence of two words “un gourmand” and “un met”.

“Un mets” is a fine dining but, etymologically, this isn’t this “met” in “gourmet”.
