The hard-hitting series “The Weight of the Nation” (HBO, 8 p.m.) concludes its two day event tonight, with some hopeful news about how kids took it upon themselves to improve the luches they receive at schools. The fried, fast-food style takeover of cafeterias has been caused by profit considerations — not nutrition or health.

There’s a two hour season finale for “Glee” (Fox, 8 p.m.) as well, combining both national competitions and graduation. With Sara Jessica Parker and Kate Hudson announced as show guest stars next season, the finale offers just Lindsay Lohan as a guest judge.

Incredibly, “Private Practice” (ABC, 10 p.m.) is returning for a new season following tonight’s finale.

A first season winner is also named tonight in the finale of “Fashion Star” (NBC, 10 p.m.). It’s between Ronnie Escalante, 32, of San Francisco and two New Yorkers, Kara Laricks, 38, and Nzimiro Oputa, 28. Because it’s done so well with its commercial tie-ins, the show will be back for a second season.

“Cougar Town” (ABC, 8 and 8:30 p.m.) won’t end its network life until the end of the month, but they are playing two new episodes tonight.

Rosie Pope returns for a second season as a “maternity concierge” on “Pregnant in Heels” (Bravo, 10 p.m.) where her excesses (and odd speech patterns) are exceeded only by those of her clueless clients.

They’re playing all five “Death Wish” (AMC, 8 p.m.) films this week on AMC.  Stop now.
