Kate Mara‘s Diet


Mara switched to a vegan diet at age 30 and and credits it for her health, energy, and ripped physique. Her inspiration was the book The Beauty Detox Solution by Kimberly Snyder. She says she doesn’t miss meat, although giving up cheese was tough. She starts her day with a green smoothie and that sets the tone for healthy eating all day long. While she’s not a cook, she still fills up on natural, whole foods and takes a pass on the junk. Besides her health smoothies, she stays hydrated with plenty of water.

Kate Mara‘s Supplements

Vitamin B12

vitamin B12

Mara prefers to keep her private life private. She follows a vegan diet which makes getting enough of certain nutrients like vitamin B12 very important.


Vitamin D

vitamin D

Many people and not just vegans run low in vitamin D, crucial for strong bones, muscles and the immune system.




If you don’t eat dairy, getting enough calcium, essential for strong bones and the heart, can also be a challenge.


Omega 3s

Vegan omega-3s

Vegan omega-3s made from algae are a smart choice to obtain essential anti-inflammatory fatty acids.




Although many plants contain iron, it is difficult to absorb, and iron deficiency leads to fatigue and anemia.




Another key nutrient that is hard to get from plants is zinc.

Mara says she was very shy growing up, and acting allowed her to fake it until she made it.

It’s in the Contract

When I’m mad at my mom, I root for the Giants, and if I’m pissed at my dad, I root for the Steelers.
