I've found a few sites somewhat similar to this one but that offer menu plans. I don't tend to follow their plans per se, but I do find it incredibly helpful for healthy lo-cal menu ideas. It just helps to add some variety so I don't get stuck in the same rut. Boring/repetitive food is definitely my worst enemy when it comes to staying on plan. I do try to use spices, vinegar, lemons etc far more to add flavour but these sites have been rather useful in inspiring new things. it seems many you have to sign up for but alas here are a few i've run into:
the self challenge - very similar to glamour's challenge last year - has sample menus, food/exercise logs, forum etc.

LHJ/BHG - weight loss planner (has a ton of annoying popups):
My Weight-Loss Planner: Welcome
or My Weight-Loss Planner: Welcome

Changing shape has a few sample exercise and diet plans (it's a pay site to get in for more)here's one: online personal trainer - weight loss programs - fitness program training
Our brisbane.com - astralian site has a week of menus:
