( Energy Kitchen )

If you’ve made a New Year’s resolution to get in shape, it’s all about diet and exercise. But relatively speaking, getting yourself on a treadmill or an elliptical for 45 minutes is the easy part; avoiding the fast-food lunches, happy hours and Chipotle splurges is what makes dropping pounds a real challenge.

So now, here’s Energy Kitchen, which opened today at 1901 L St. NW. The New York import, which is the brainchild of the guy who co-founded Vitaminwater, Mike Repole, promises to let you continue eating all the fast food you crave without piling on calories. Nothing on the menu has more than 500 calories. “Fast food, not fat food,” goes the slogan.

Without having tasted anything on it, the menu appears to offer promise for those who would proritize Five Guys over the five food groups. There’s actual meat in the burgers! Choose from bison, sirloin, turkey, chicken or veggie, with toppings like turkey bacon and fat-free cheddar cheese (we’ll skip that, thanks). Energy Kitchen’s bacon cheddar burger tips the scales at a reported 490 calories (compared to 630 calories for a Little Bacon Cheeseburger at Five Guys). You can even order fries — baked, of course — for an extra 190 calories.

Energy Kitchen also serves breakfast, wraps, smoothies and frozen yogurt. It’s open Monday-Friday from 8 a.m. to 9 p.m. and Saturday from 8 a.m. to 4 p.m.
