How Many Calories Are in a Piece of Paper?

Calories are a measure of the energy content in food. When counting calories for weight loss or maintenance, most people only consider the calories they consume through eating and drinking. But have you ever wondered if other things around us contain calories too? What about something as innocuous as a piece of paper?

Paper Contains Very Few Calories

The answer may surprise you - paper does contain calories! However, the amount is negligible. Let's take a look at why:

Paper is made from cellulose fibers that come from trees and plants. Cellulose is a complex carbohydrate, and like other carbs, it does provide calories. However, cellulose fibers cannot be broken down or digested by the human body.

That means the calories in paper are not bioavailable to us. So even though paper contains caloric energy, our bodies cannot access or utilize those calories. From a food calorie and nutrition standpoint, we can effectively say there are no calories in paper.

Calculating the Calorie Content in Paper

While we cannot digest or use the calories in paper, we can still calculate an estimated calorie amount out of curiosity.

Most copy paper contains about 5 calories per sheet. This is based on the fiber content and the energetic potential contained within those fibers. While precise amounts can vary slightly depending on the paper quality, size, thickness, and pulp source, 5 calories per sheet of 8.5 x 11 inch paper is a reasonable estimate.

So if you had a whole pack of 500 sheets of copy paper, it would contain about 2,500 calories worth of raw cellulose energy. But again - the human body is unable to extract or assimilate those calories for energy needs.

Calorie Differences Between Raw and Processed Plant Foods

To understand why the calories in paper are inaccessible, it helps to compare how calories in whole raw plants differ from processed plant foods.

For example, a raw potato with skin contains starches and complex carbs that our bodies cannot fully breakdown. But when that potato is cooked, the heat breaks down the rigid cellulose structures. This makes nutrients more bioavailable and digestible to extract calories.

Paper production also uses heat, pressure, and mechanical processing to break down wood into pulp. However, the pulp is then reconstituted into sheets of fiber. Our bodies do not have the enzymes needed to further breakdown those rigid cellulose fibers back into a digestible, calorie-containing form.

Calorie Changes During Paper Recycling

What happens to the calorie content when paper gets recycled? As it turns out, recycling has little effect on the calories in paper.

Recycled paper pulp has already undergone mechanical and chemical processing. Further recycling maintains the cellulose fibers in that rigid, indigestible form. So recycled paper will contain the same negligible calories that cannot be extracted by the human body.

Counting Calories in Paper for Weight Loss

When tracking your food intake and calories for weight loss or maintenance goals, you can rest easy knowing paper contains no usable calories.

Here are some reasons why the calories in paper should not be factored into your intake calculations:

• Paper calories cannot be digested or absorbed by the human body
• The calorie content in paper is negligible and inconsequential for weight management
• Your body derives zero energy or nutrients from eating paper
• Tracking paper calories would be inaccurate and counterproductive

The bottom line - don't worry about counting calories in paper products. Focus your calorie tracking efforts on the foods and beverages you actually consume. This will provide the most accurate guide for reaching your diet goals through mindful calorie balance.
