Everything on the label refers to one serving, not automatically the entire package.

If a bag contains:

• 2 servings 
• and label says 220 calories 

Then eating the whole bag =

The same rule applies to:

• fat grams 
• carbs 
• protein 
• sugar 
• sodium 

Unless the package is listed as 1 serving, the label is not for the whole container.

Know How Calories Are Created

Calories come from the three main macronutrients:

• Fat = 9 calories per gram 
• Protein = 4 calories per gram 
• Carbohydrates = 4 calories per gram 

This helps you understand what the food is mostly made of.

If a serving contains:

• 10g fat 
• 20g carbs 
• 15g protein 

Calories would be approximately:

• Fat: 10 × 9 = 90 
• Carbs: 20 × 4 = 80 
• Protein: 15 × 4 = 60 

 (Labels may vary slightly due to rounding.)

Fiber Is a Carb, But It Behaves Differently

Fiber is listed under total carbohydrates, but your body does not digest and absorb fiber the same way it does sugars or starches.

That means fiber often has a smaller impact on blood sugar and usable calories.

Because of this, many people look at:

Formula:

Example:

• Total carbs = 25g 
• Fiber = 8g 

This can be useful for blood sugar control, appetite control, or lower-carb eating plans.
