1. Eat What Makes You Feel Good

Anne used to be a vegan. However, when she started shooting Interstellar and was forced to wear a 40-pound spacesuit on a daily basis, she changed her eating habits. "I just didn't feel good or healthy," she told Harper’s Bazaar, adding that she felt "not strong." One day she caved with a fresh piece of fish while in Iceland—"from a stream I could see from where I was sitting," she explained. The following day she "just felt better."

2. Put Down the Bottle

Anne confessed to Tatler in 2019 that she had quit drinking. “‘My issue is I just love it. So. Much. But the way I do it makes me unavailable for my son. My last hangover lasted for five days. I’d earned it: it was a day drinking session with friends that went into an evening birthday party with one of my drinking buddies. I will never be that person who can nurse a glass of wine throughout an entire evening,” she said.

3. Avoid Crash Diets

Anne is no stranger to crash diets. To prepare for her Academy Award winning role as Fantine in Les Miserables, she had to lose 25 pounds fast. Anne explained to PeopleTV's The Jess Cagle Interview that the weight loss put her in such a bad place couldn’t enjoy the trophy. "I was just not in a grounded place in my life," she said. "I never wanted to go on and on about it, but that weight loss was not a long-term good thing for my health, and it took a really long time to come back from it. In order to do the transformation to play Fantine, I'd lost a lot of weight in about two weeks. I lost an unhealthy amount of weight in a short amount of time, and I was still really sick because of it."

4. Exercise Moderately

Anne is not obsessed with exercise. "I'm not a natural wellness warrior,” she confessed to Shape. “I have friends who go to longevity conventions. They take crystal baths. For me, I try to make it to yoga three or four times a week. It's a different story when I'm working on a film, though. I work out with a trainer, and I do a lot of strength training and HIIT when I need to do that.”

5. Avoid Processed Food

Anne isn’t super strict about her diet but does stay away from one type of food. "With eating, my number-one thing is trying to buy food that doesn't come in packaging,” she told Shape about her diet. “Beyond that, I try not to eat red meat, and I try not to eat pork.”

6. Maintain Balance

Anne has a “low-key” approach to wellness. “The balancing [of my approach to keeping in shape] is important to me. My go-to for a lot of my life was to feel bad about myself, and I just don't want to do that anymore,” she told Shape.

7. Live in Gratitude

In the latest issue of Interview, Anne explains that living in gratitude is the key to happiness. “I mean, I’m human, I have moments. But like I said, when gratitude is an option, I’m going to choose that every time,” she explains. “It’s what I want. I don’t know if it’s that I’m at a point in my life, or that the world’s in a place where it is, but there are no guarantees, and I’ve lived long enough to know that the only thing we can count on is the present moment. I don’t want to give anything away to unnecessary drama or negativity. I’d rather just be present with these things that I love.”
