Yesterday, we sat through a session for NBC's "The Biggest Loser," which was lots of talk about diet and exercise, followed immediately by a snack break.

Yes, there's more than one reason that press tour sometimes feels like a cruise to nowhere.

Now we're listening to the cast and crew of NBC's "Thick and Thin," a sitcom about a formerly fat girl (played by Jessica Capshaw, whom none of us can even imagine fat) whose still-heavy mother (Sharon Gless) and sister (Amy Halloran) are having nearly as much trouble adjusting as she is.

This leads to one of those endless discussions of weight and Hollywood that never seem to come up when we're actually confronted with the bonier specimens paraded before us day in and day out, and Gless, who looks as if she's actually lost a fair amount of weight since her early days on "Queer as Folk," tells about the "horrible" reaction in Hollywood to her weight gain after "Cagney & Lacey" left the air.

When she pointed out to her husband, producer Barney Rosenzweig, that she was no bigger than her former co-star, Tyne Daly, but was getting much more grief, she says he replied, "Honey, they can't forgive the blonde."
