I mix in the Luna and the Slim-Fast Meal Replacement bars just to shake it up with the Lites sometimes. They Slim-Fast are about 30 calories higher so if I use one of those I up the water and toss on a few extra crunches to the work-out.
The South Beach Diet bars have pretty much the same nutrionals as the LA Lite beverages, I'm now going to start tossing one of those in every so often. On sale they can be $3 for six bars--a big savings over the Lites.
