Health philosophy: Find a way of life that is enjoyable and delicious that also supports good health. In being well, you create a good life in every way.

Food philosophy: Think of foods as being divided into three categories: Usually, sometimes, rarely. (Note: no never!) When I cook at home, I really try to focus on the usually foods, she says. Because I live in New York, when I go out, there are plenty of opportunities to get the sometimes and rarely!

Vitamins and supplements: She doesnt take any. If you want to take one as an insurance policy, thats fine, but the only way to assure youre going to get what you need is from food, she says. Im not against supplements, per se, but I also dont think theyre the answerand for the average healthy person, I dont think theyre necessary.

Motivational trick: Think of the payoff. Sometimes Im just not in the mood to cook. The key is knowing I have these quick recipes in my back pocket that frankly taste better than anything I can order in, and are healthier and cheaper, she says. So OK, the payoffs there. Then I turn up some music and I start drinking a little wine, and suddenly its not so bad its fun!

Favorite healthy meal: I hardly ever make the same thing twice! she admits. But a typical meal could be as simple as my honey mustard salmon, a quinoa pilaf and some kind of seasonal vegetable like crispy roasted Brussels sprouts or maybe some beautiful, ripe tomatoes with olive oil.

Secret weapon: Spices. Im always looking for that sweet spot where healthy and delicious meet, she says. Spices are great to experiment witheven a sprinkle of curry powder on your cauliflower before you roast it, or some smoked paprika on your eggs in the morning.

Favorite workout: Yoga once or twice a week, indoor or outdoor cycling, hiking. Sometimes Ill go for a run. Im maybe the slowest runner in the entire world80-year-old speed-walking women pass me! she says, laughing. But I dont care. Im out there doing it.

Favorite healthy snacks: While she tries not to eat much between meals, Ellie almost always has a little something at 4 p.m.: fruit with almonds or cheese; or a piece of chocolate. In the winter, lately Ive been into making hot cocoa with skim milk and real cocoa powder, a little bit of sugar, she says. If you make it with those pure ingredientsand not too sweetyoure getting so much nutrition and a really satisfying snack.
