The actress dishes on her new book and (very public) diet.
Valerie Bertinelli

6:45 a.m. Every morning is different, but I always turn on the coffeemaker and grab the newspaper crossword--I'm a puzzle junkie.

7:15 a.m. This morning, I drop off my boyfriend, Tom, for his flight to Arizona. I stop at Gelson's grocery store--I'm making spaghetti and meatballs for dinner tomorrow.

8:30 a.m. I wake my son, Wolfie, who's 17--he has school in the house because he's on tour with Van Halen, playing with his dad. I have a cup of coffee with whole--not skim--milk!

9 a.m. For breakfast, I have a Jenny Craig sandwich--an English muffin with Canadian bacon and eggs. I add fat-free cheese and mustard.

1 p.m. I squeeze in a workout on the elliptical and do jumps and abs.

2 p.m. I'm usually hungry after exercising so lunch is a Jenny Craig turkey burger for me and a grilled ham-and-cheese for Wolfie.

4 p.m. If I'm feeling snacky, I grab pretzels or apples and peanut butter. After three decades of dieting (and writing a book about it), I know what to do; it's about sticking with good habits. I hope women identify with my book, Losing It--And Gaining My Life Back One Pound at a Time ($26, Free Press), and say, "That happened to me."

7 p.m. For dinner, I make a big salad and Jenny Craig chicken carbonara while I watch The Office on TiVo.

11 p.m. Bed! I'm so exhausted at night that I can barely keep my eyes open long enough to wash my face.
