Go grocery shopping

Once you have planned your diet and meals, prepare a grocery list and go out and do some shopping. I usually prepare all my meals and grocery list on Sunday mornings. I usually hit the grocery store in the morning when nobody's there because I can't stand waiting around in a grocery line:(

When you plan your meals and groceries, you will A) Eat what you buy; And B) Save a whack of money on items you will never eat or use.

However, try and hit the grocery stores when it is convenient for your schedule. Also, get into the habit of going to the grocery stores on a consistent basis. This way, it gets much easier to do over time.
