1. She Worked With A Nutritionist

Her Nutritionist, Dr Philip Goglia, explained the importance of bridge meals and between meals snacking on healthy options. "The purpose of a bridge meal is to get to lunch so that you don't overeat lunch," Dr Goglia said. "You're using fat metabolism and that will be your bridge meal to get to dinner so that dinner is an appetite environment that will not allow you to crave carbs because you've already eaten… you're kind of full. You're not in low blood sugar."

2. She Connects Her Workouts To Her Character

When she got the Marvel role, Bri did a lot of strength training to connect with her character. "A huge part of [Captain Marvel] is her strength," Brie said. "I knew if I could go through that experience, I would get closer to her and I'd understand [her]."

3. She Believes Everything In Moderation

In moderation, fat and sugar don't always need to be bad. "The most recent science has shown that a little bit of fat and a little bit of simple sugar will actually increase intensity rate while you train early in the morning… and allow you to still continue to train and burn fat," Goglia said. "That really does start your engine for you."

4. She Does Resistance Training

Brie Larson works hard to strengthen and tone her muscles. She works her entire body through resistance training to also help improve endurance. "One strength training tip: Don't forget to breathe freely when you're lifting the weight. Most people think that they're breathing when they're doing strength training exercises, but they may be holding their breath. It's important to inhale and exhale fully between each repetition. The key is to avoid straining when holding your breath. You may find it helpful to exhale during the more strenuous phase of the exercise and inhale during the less strenuous phase," says the Mayo Clinic.

5. She Works On Her Balance

Brie Larson knows the importance of working on your balance, especially when training for a role like Captain Marvel. She stuck to a pretty strict diet majority of the time, but once in a while would allow herself a donut or a cookie. "We focus on a Mediterranean-style diet of eating for optimum heart health. The Mediterranean diet is abundant in fruits and vegetables, grains, fish, extra virgin olive oil, nuts, and seeds. Starting off with eating more meatless meals will definitely get you closer to heart health. Incorporating beans, legumes, any kind of nuts and seeds, and meatless products like tofu, tempeh, if you want to get adventurous into your diet a little more regularly. I generally say start with one meatless meal a week, replacing a meal of meat, ideally red meat, with a meatless meal," says Julia Zumpano RD, LD Preventive Cardiology, to the Cleveland Clinic.
