Luna Bar

Lower-calorie energy bar

  • Few calories from sugars
  • 170 to 190 calories per bar
  • 70 percent organic ingredients
  • Balanced carbs and protein
  • 3 to 5 grams of fiber per bar
  • Some don't like the crispy texture
  • Not as big as some bars, may not be as filling

The Luna Bar is marketed as a bar for women, with added vitamins and minerals chosen to meet women's nutritional needs. But judging from reviews, lots of men like them, too. Luna Bars have 8 to 9 grams of protein and 25 to 30 of carbohydrates; they're low in saturated fat and sugars. Those who've tried them on camping trips say they don't melt in the heat and can be eaten when frozen. Luna Bars are lighter, smaller and crunchier than top-rated Clif Bars (*Est. $1.25), and they also have fewer calories. If you like the idea of a bar with no processed ingredients and no additives, experts say Larabar (*Est. $1.35) makes the best-tasting whole food bars, though they cost a little more and don't have as much protein.

3. Prevention Magazine

Registered dietician Elizabeth Somer helps the authors identify seven energy bars, including Luna Bars, that are low in calories but provide enough carbohydrates to give you a quick energy boost. They also have enough protein to prevent an energy crash after the carbs have been burned. A poster linked to the article gives each bar's description, comments from testers, a list of its nutrients, and a list of the available flavors. Testers liked the Luna Bars; the review says they "loved the flavor variety" and found them "light, not dense, unlike most energy bars."
