Hosted by cooking experts Harry Eastwood, Allison Fishman and Candice Kumai, food lovers everywhere learn exactly how to turn recipes for their favorite indulgences into healthy low-calorie dishes without sacrificing taste.

* House (8 pm/ET Fox)
So, is it just insomnia that's keeping House awake and Amber (Anne Dudek) in his life? He did fall asleep last week, yet she still won't go away. Look for this situation to build to season-climax proportions. (The finale is next week.) After all, you know what happened to the hot doc on that ABC medical show who had dead-guy hallucinations. Meanwhile, the House-Cuddy thing could heat up, but will Cameron-Chase cool down? As for tonight's patient, she's a ballerina whose skin is falling off.
* Medium (9 pm/ET NBC)
Allison means business in a two-hour spellbinder tonight. (The conclusion airs next week.) Allison resigns from her post at the DA's office when she's lured by a fellow psychic (Tracy Pollan) to work at a vast and formidable corporation. The lavish, big-money corporate lifestyle enraptures Allison, yet she's also haunted by visions of a serial killer's murderous fury in Phoenix. Then there's her new boss (David Morse), a territorial company bigwig who forbids Allison from sharing her dreams with anyone else - including crimefighters Devalos and Scanlon. In DuBois family affairs, Ariel begins taking pills, hoping they'll block out her ghostly visions.
* Inside the Actors Studio (7 pm/ET Bravo)
After a three-month hiatus, James Lipton's enduring (and endearing) interview series returns with a conversation with Emmy-nominated comedian and actor Denis Leary. This Denis is no menace: The Massachusetts-born Leary kick-started his career in the early 1990s with a kinetic, chain-smoking stand-up act before advancing into filmdom, which included star turns in 1994's The Ref and 1996's Two If by Sea. Leary added fire to his career in 2004 by taking on the role of veteran firefighter Tommy Gavin in Rescue Me, a series that he cocreated.
* New York Goes to Work (10 pm/ET VH1)
This time it's not doctor, lawyer or Indian chief. How about ranch hand, baker or exterminator? Tiffany "New York" Pollard, who has been a reality-TV fixture on VH1, will attempt whichever of those three occupations receives the most viewer votes in the series opener. If she's a success and impresses her new boss, there's a $10,000 bonus in it for her. But if she quits or fails, there's no bailout for her; she'll get nothing.
