When we put ourselves onto a diet, we are committing to the same thing everyday: planning for foods that we're allowed and not allowed to eat and exercise that must be done in order to feel good about ourselves. Eating a healthy diet is much different than being on a diet.
What I found when I used to diet was that, along with having all of my meals pre-arranged each day, the rest of my daily activities also became rigid. I began living a habitual life of predictability because I didn't want sporadic decisions to ruin my plan.
What I missed out on was the freedom of living in the moment and the liberation of making decisions as the day progresses. It started to feel like I was just biding time until I could get to that next meal, counting down the hours before I could eat again. It was a woman-made prison with unyielding bars manufactured by me.
My challenge to you is to do one thing today that breaks out of your routine. Try something new and let yourself freely experience it. Whether it's food and diet-related or something altogether different, go for it. And have fun!
