I always had an idea of packing my lunch，but putting this healthy habit into practice was a different story.I always felt embarrassed when I saw my coworkers with their cute containers filled with fresh food that looked much more delicious than whatever I had grabbed out of necessity.

　　Sometimes，I would be inspired (激励) to have a productive Sunday afternoon when I would cook my favorite food or buy a ton of groceries that I would never finish.However，once Wednesday rolled around，I would be back on the street，trying to find out what sounded good to eat.Once I got into the habit of packing my lunch the night before and remembering it before I left the house，making this a daily habit became natural.Here's why you should try it，too.

　　At first，the idea of packing my lunch felt like a sacrifice (牺牲)，but since I started bringing healthy food to my office，I have not looked back.I'm able to bring foods that are rich in fiber and protein to make my brain full of energy as I write，and I am also clear of the ingredients that make my blood sugar rise quickly. It was the big kicker for me to keep this healthy habit.

　　Portion control (分份控制) has always been a big problem for me.If there is food on my plate，I'm going to eat it.By packing my own lunch，I'm easily able to manage portions and know my ingredient choices.Eating a cleaner and lighter lunch not only supports my general weight­loss goals，but also makes space for the occasional weeknight dinner that I can enjoy freely.

　　When developing my plan for 2016，I made a point to get real about the costs.I had no idea how much money I was spending on my lunch every week until I looked at my credit card statement.It's hard in downtown San Francisco to find something that is fresh，healthy and filling for under $10.That means $50 a week I could be saving.It's unbelievable!
