Suppose a portion of food is twice the amount service as listed on label how do you determine many calories are in person?

To determine the number of calories in a person who consumed a portion of food that is twice the amount of the serving listed on the label, you can follow these steps:

Identify the serving size listed on the food label. This is usually expressed in a specific unit of measurement, such as grams or ounces.

Multiply the serving size by 2 to determine the amount of food consumed.

Find the calorie content per serving listed on the food label. This information is usually provided in the nutrition facts panel.

Multiply the calorie content per serving by 2 to determine the total number of calories in the portion consumed.

For example, consider a food label that lists a serving size of 100 grams and a calorie content of 200 calories per serving. If a person consumes twice the amount of food (i.e., 200 grams), you can calculate the total number of calories as follows:

Serving size: 100 grams

Calories per serving: 200 calories

Amount consumed: 200 grams (100 grams x 2)

Total calories: 400 calories (200 calories x 2)

Therefore, the person consumed 400 calories from the portion of food that was twice the amount of the serving listed on the label.

Remember that this calculation assumes that the nutritional content of the food remains consistent throughout the entire portion consumed. If there are any variations in the nutritional content, the calorie count may vary accordingly.
