Running can be a polarizing (两极分化的) subject. Most people fall into one of two camps: those who love running every morning, and those who would sooner do anything to avoid it. For most of my life, I was planted in the second camp.

I always hated running. I remembered entering a neighborhood 5K race with my dad at age 12; I also remembered that I came in last in the race, followed by only the police car driving patiently behind me. Three years later, I didn’t make the junior volleyball team because I couldn’t run a mile in under 10 minutes. Every time I ran, I felt as though failure — in some form or other — was the only possible result.

The summer after my freshman year, though, I took a job at a summer camp in Connecticut, where I got paid to be a kid again. I spent my days keeping an eye on different camp activities. When it came to exercise, running was my only choice. So, I made a promise myself: Every day, I would run for a while. By most runners’ standards, it wasn’t far; I guessed it was only about a mile. But I decided to do it every day, no matter how long it took. The exercise lasted for 61 days — the entire time I spent at camp that summer.

I started to feel better about myself. But to my great surprise, I learned to love running, too. I went from fearing the sport to loving it. I’ve finished seven marathons (马拉松赛跑) and more shorter races than I can remember, and now I am a running coach. These were the secrets I discovered to changing my way of looking at life.

I used to overeat. I’ve never been significantly overweight, so people are surprised to hear this. When you think of overeating, you think of someone who is above their natural weight range(范围), right? Well, I used to purposefully undereat as well. I was able to keep my weight within some control, but only through a lot of physical and mental pain.

Here’s a glimpse(一瞥)into my life as a first-year university student:

Friday: Go to a party and eat a lot of chips. Feel guilt and regret. Vow (发誓) to wake up and run an extra mile.

Saturday: Run 6 miles, come home and only eat a tiny breakfast. Eat like a bird for the rest of the day. Feel proud of myself.

Sunday: Study and snack on chocolate chips all day. Feel sick.

Monday: Head to class with no snack and no money so that I can’t buy any food. Feel hungry but full of willpower. Go home and overeat at dinner. Feel out of control.

My feelings were on a constant pendulum shift. I was proud and in control one moment, and then full of regret and out of control the next. It was exhausting.

As I studied nutrition and human anatomy(人体解剖学) in university，I started to learn just how amazing the human body is! The human body is an amazing, self-regulatory system. It knows precisely how much food it needs. When I learned this, my whole world changed. I stopped trying to manage my eating with willpower. Instead of trying to power through my hunger, I would provide my body with wholesome foods, so I would feel hungry less often.

This process definitely took some work and reflection, but after a while it became second nature. Eating has become a joyful experience, instead of a source of stress and worry in my life. All my eating is now guilt-free! I shamelessly eat unhealthy snacks without regret. Of course, the majority of my food intake does come from whole, healthy foods that are close to nature.
