I can understand you being worried. The combination of him not eating, lying about it and feeling down does sound difficult to witness.
Unfortunately, you'll need to be careful that he doesn't perceive you as getting on his case and interfering with his autonomy. I would drop it for now as your encouraging him to eat could somehow become a reason for him not to, in a perverted way.
It does sound really trying though. Good luck.
