Eileen maintains that exercising fuels healthy eating. "It helps me in eating!!! That this is essential!!!!

Eileen loves soaking in hot water, either in a bath or hot tub, like she is in this phot. "With a landscape like this I don't have a favorite photo!!" she captioned it. How can baths do your body and mind good? They have been linked to better sleep and even found helpful to minimize anxiety and depression.

"Every day I eat very well. I eat a lot and try to make up for it by exercising and playing sports. I also try to balance my diet. For example, if I eat a lot at lunch, I try to eat a little less at dinner. But I never go without food, no matter what my weight is," Eileen told G1 about her diet. "I always ate a lot and still managed to win the Miss Colombia pageant."

Eileen also makes sure to hydrate. According to the U.S. National Academies of Sciences, Engineering, and Medicine men should drink about 15.5 cups (3.7 liters) of fluids a day and women about 11.5 cups (2.7 liters) of fluids.
