I’m guilty: I snooped around Jillian Michaels’ dressing room. I was left alone for a few minutes while she filmed part of her new show, Sweat Inc., and I spied something far too tempting to ignore: her stash of snacks.After all, the fitness entrepreneur, 41, is a powerhouse, and I wanted to know what fuel she’s putting in her machine. Her snacks include organic brown rice crackers; dry roasted, salted almonds; and root vegetable chips.And, boy, does Jillian need to keep her energy up. In addition to this show, which debuts on Spike TV this month, she’s shooting an E! channel docuseries, Just Jillian, that captures her life at work and at home with her partner, Heidi Rhoades, and their two kids, Lukensia, 5, and Phoenix, 3, set to air in January. She’s also busy writing a new book for mothers-to-be, Hot Mom, Healthy Baby, and has just launched a fresh-food line called Slim Soul (in select supermarkets). And that’s on top of the Impact fitness wear she created for Kmart. Jillian is still in full exercise garb because she’s just finished a workout on camera—but despite the name of her show, she isn’t breaking a sweat. “I take better care of my body now than I did at 20,” Jillian says as we walk across set to grab lunch. “I got kids. I’m like, ‘I need to be around for a while!'”RELATED: Where to Buy the Cool Clothes Jillian Michaels Is Wearing in Our October IssueBack in her dressing room, she sits cross-legged on the floor.

I have grass-fed beef once a week, and farmed shrimp and ocean-caught salmon, and sometimes some sole or tuna. I’m looking at the planet and really starting to see how our food policy and food practices are destroying the world. Even grass-fed beef is so bad for the planet. And we’re fishing out the oceans.Do you cook at home?We’re terrible cooks! Well, Heidi is a good cook, but she doesn’t have a ton of time. I am a terrible chef, so I hate to admit this, but one of the things we do is have a couple of restaurants that feed us—literally. The more I work out, the more carbs I need. I stopped eating sugar in December. Carbs, yes, but straight sugar, no.Is there one food rule you think we should all follow?I don’t believe in all or nothing.

There’s a scientific explanation for why it’s like that: “Since oil glands are mostly under hormonal control, they can become less active as your body changes over time,” says Dr. Francis. Turning up the heat on your dryer or curling iron only adds to the parching problem.TREAT ITRestore your hair’s natural lipids with a weekly fix such as Kérastase Paris Resistance Masque Therapiste ($34; amazon.com), which packs hydrating plant sap plus peptides and amino acids to strengthen abused follicles.STYLE ITCoat damp hair with a thermal protectant that hasceramides; they bind to hair and reduce breakage, found a study in the International Journal of Cosmetic Science.

With daily use, you can expect results in as early as 12 weeks. Also FDA-approved to spur hair growth: low-level red-light laser therapy.
