### Activity Overview / Details

Students will work on the worksheet calculating grams to calories.  Teacher can use this activity to check understanding.  Correct as a class reteaching any area of concern.

Teacher will continue to make connection between calories consumed and weight as it relates to the percentage of each nutrient.

Here explain that not all calories are the same.  Calories as received from carbohydrates will be used first.  This energy will be burned first, followed by protein and fat.  Excess carbohydrates, protein and fat will be stored in the body as body fat.  Here is where we see weight gain if the energy stored is not burned.

Referring to the recommended daily calorie intake for teens tell students that each nutrient has a recommended percentage.

Recommended nutrient sources for calories

Carbohydrates                              45-65%   (both male and female)

Protiens                                          10-30%   (both male and female)

Fats                                                  25-35%   (both male and female)

Excess nutrients are stored as body fat if the amount recommended is exceeded on a daily basis.  Lack of exercise or activity can increase the amount of stored body fat.

Example will be given.

We have seen in our first worksheet that in problem #1, Sydney consumed 162 calories from fat.  The recommended percent of calories from fat is 25-35%.  This is more than the recommended amount.

The recommended calories from fat  for this meal is  71 calories.  The fat calories consumed were 162, more than 50%.

From this what conclusion can we draw?   Allow for students responses.
