Depending on how you define your lunchtime, believe it or not, it is actually now possible to have liposuction done in the amount of time a lot of people would take for their lunchtime break. So from the point of view of the time it takes to do the procedure, then yes, lipo can be performed in a lunch time.

This is largely due to the incredible advances that have been made with liposuction techniques as well as advances in liposuction technology and equipment.  These advances have lead to the development of entirely new liposuction procedures, namely Smartlipo and Vaser lipo.  Before, liposuction was considered to be a reasonably big surgical procedure.  Now, even though it is still a cosmetic surgery, it is considered to be a minor one.

When used on smaller pockets of fat, both Smartlipo and Vaser lipo can be performed using only local anesthesia.  This means you won't need a lengthy preparation time in the clinic; and you usually won't need an overnight hospital stay either.  If you opt for very light or no sedation at all (this is often possible with these advanced procedures), you can usually leave shortly after your lunchtime lipo procedure.

If you were expecting to return to work or to your normal activities straight after your procedure, this is Where the term Lunchtime Lipo could be said to be a myth.  You will need to go home and take it easy. After all, even though you were in and out of the liposuction clinic quite quickly, your body will need some time to recover from the procedure.

Areas usually considered suitable for lunchtime lipo are - double chin, abdomen, love handles, thighs, upper arms, back contouring, or even a combination of one or two of these areas.

So even though this procedure can be referred to as Lunchtime Lipo, I still wouldn't take that moniker literally.  You will still need to take it easy for a day or so after which you can slowly resume your normal activities.
