You’re back at your desk after lunch and you’re feeling raring to go, ready to take on any project, ready to...nap?

A whopping 72 percent of respondents to a recent Blimpie survey revealed they feel either more tired or the same after eating lunch, rather than becoming rejuvenated or more energetic after consuming their lunchtime meals.

One of the main problems: Americans aren’t eating the right kinds of foods for lunch. We don’t eat food that fuels our mental activity. And, if we’re not eating lunch that fuels our brain power, we’re not going to be working as efficiently as we could, or to the best of our abilities in the afternoon.

“People simply feel better when they have good food in their stomach. People think better and make fewer mistakes if they are filled with the right kinds of food,” said Tony Conza, Blimpie International founder and CEO.

There are several ways to make your lunchtime meal more of a power boost with very little effort. For example:

• Add a piece of fruit to your lunchtime routine.

• Include plenty of vegetables to any sandwich you may eat.

• When you’re eating a salad, be sure to add chicken or tuna — both great sources of protein.
