Introduction

In addition to the submarine sandwich Subway offers, the chain also serves wraps and salad as well as baked goods and pastries including cookies, donuts and muffins.
 As we progress into the fast-paced life of the 21st century, where everything’s all about convenience, the experience of eating fast food is so routine, so ordinary, so commonly seen. These fast food giants mentioned above are “taking over” this fast-evolving world, as more and more people are eating fast food to the extent that it has become an vital part of our society. Most people know that fast food is not the healthiest choice when it comes to the wide variety of choices in the food world, but choose to eat it because of the speed, low prices, convenience and appeal to our taste buds that it offers. We hope to create greater awareness on the adverse effects of this popular culinary choice by using a fictional character in a made up scenario and showing the effects of consuming fast food on a regular basis on the weight of a healthy 14-year old girl who exercises 5 times a week, today.
