The Restaurant Dieter was harsh on Darden Restaurant Group and Michelle Obama recently. The chain announced some pretty modest efforts to make its menus healthier, but from the purple prose, you’d have thought Darden conquered obesity.

Now comes the news that the chain — which operates Olive Garden, Red Lobster and others — is suffering financially. One of the reasons cited is commodity costs. Here’s hoping it gives the chain incentive to rein in some of the enormous and calorie-laden portions it serves.
