Current UFC bantamweight champion Ronda Rousey is one of the most dangerous women on the planet.
The MMA star is currently ranked as the number four pound for pound fighter in the world.
She is currently undefeated and is yet to go the distance in the UFC, and she looks as close to unbeatable as you're likely to get.
In order to stay on top of her game Rousey maintains a strict diet and high intensity training regime, here's the 10 essential foods she relies on to stay on top.
Water
Water is obviously essential for any athlete to maintain high levels of fitness but finding the right balance can sometimes be difficult.
The recommended water intake for most people is two litres per day but Rousey is made to drink up to eight litres by her dietician to maintain her hydration.
Coffee
One day we hear it's bad for us the next day it's good, it's hard to know what the benefits of drinking coffee really are but Rousey drinks it every morning as a stimulant prior to her morning training.
Chicken
Ronda opts for chicken over turkey for her main source of protein. However she's not chowing down on chicken wings and goujons.
The UFC champion ejoys free range grilled chicken as she finds it easy to monitor calorie levels.
Coconut Oil
