Here's a small diet tip from none other than mega popstar Beyonce: Skip the drive-thrus. The sensational singer was recently quoted as saying, "I love all the greasy stuff even though I know it's not good for me. I have to be very careful for months on end about what I eat. And then suddenly I will have a moment of weakness and have junk food. I just try and whiz straight past the drive-thrus now because it can be so dangerous."

Maybe too many visits to the drive-thru is the reason she resorted to the lemon juice diet a while ago? Regardless, this is good advice -- drive-thrus are way too convenient and way too unhealthy. Keeping your fast food indulgences to a minimum is an effective, easy and inexpensive way to keep the numbers on the scale down.
