Rob Kardashian -- All Signs Point to Dramatic Weight Loss (PHOTO)

Rob Kardashian not only looks like he's lost a lot of weight, there's a not-so-subtle message he seems to be telegraphing.

Rob posted this Saturday, presumably at a restaurant where he was eating a salad.

The phantom Kardashian has resurfaced this week after a long absence, and it's clear he's ready to show the progress he's made in the weight department. Rob's been working with trainer Gunnar Peterson, with the goal of losing 100 lbs.

The drink on the table's interesting ... could be an ice tea, but maybe a red bull and vodka or a margarita. Door number 1 would be the wisest choice.

Good luck Rob.
