A typical protein bar is 220 kcal, with 20 g of protein, 22 g of carbs and 8 g of fat. That protein is the reason people buy them.

Calorie wise it's in the same area as a chocolate bar. The difference is what's inside, and the protein keeps you full for longer.

It's handy after the gym or on a day when lunch didn't happen. It doesn't make a snack lower in calories, it makes it more filling.

Tips

  1. 1Have it instead of a snack, not as well as one.
  2. 2Keep one in your gym bag so you don't raid the vending machine after.
  3. 3Pick a bar you actually like, or it ends up as a second snack.

Where it comes from

The protein bar's ancestor has a link to space. Pillsbury food scientist Howard Bauman, whose team made the first solid food eaten by a NASA-astronaut in 1962, created Space Food Sticks in the late 1960s, a chewy snack rod with balanced protein, carbs and fat sold on the back of the Apollo missions. They are seen as the forerunner of today's energy and protein bars.
