How to calculate calories in Protein bar
Multiply the calories per 100 g by your portion weight, then divide by 100. For the reference 60 g portion, the calculation is:
350 × 60 ÷ 100 ≈ 210 kcal
Reference portion: bar (60 g). This is an example amount, not a recommended portion. Weigh your food when possible: a cup, slice or piece can vary in size.
