The Men's Health website has a great section called Eat This, Not That. It's very heavy on promoting the book of that name, but has some good information and is worth a look around.
It contains better choices and options at fast food/sit-down restaurants and grocery stores. What really caught my attention was the fact it's not cutesy and improbable suggestions like "order a salad instead of a burger!" but realistic swaps.
For example, the Krispy Kreme Original Glazed Doughnut has 200 calories versus Dunkin' Donuts Glazed Cake Donut at 330.
The section is expansive, so clicking one of the four tabs at the top (Restaurants, Groceries, etc.) leads you to at least 4 or 5 tabs.
Here's the link.
