A standard hard bar is about 118 calories; the chocolate-dipped ones run higher. On the energy-density scale, 471 kcal per 100 g puts granola bar at the very high end. Fiber is the standout at 5.3 g per 100 g, which slows a portion down more than the calorie count suggests.
A typical serving (1 bar, 25 g) has about 118 calories, and 100 g has 471 kcal. Calories scale with weight, so double the portion means double the number.
There are 10.1 g of protein in 100 g of granola bar, which works out to about 2.5 g per serving (1 bar). Treat it as an energy source rather than a protein source.
Sugar comes to 28.6 g per 100 g, so 1 bar (25 g) delivers roughly 7 g. That sugar is already counted inside the calorie figures on this page.
Every value on this page comes from USDA FoodData Central, entry 167542 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
