What Goes in Must Come Out

Kathy Kelly


Students devise a plan for modifying caloric intake and energy expenditure. Each week, they track information and record it in their journals. They use feedback to adjust their plans and then assess their progress.


The student writes text, notes, outlines, comments, and observations that demonstrate comprehension of content and experiences from a variety of media.

Demonstrates ability to research, conduct and evaluate a long term project or experiment.

The student describes the principles of training and conditioning for specific physical activities.

The student knows how to use a journal to document the benefits of participation in physical activity as part of an individual wellness plan.

The student understands the relationships between caloric intake and energy expenditure.

The student plans and participates in an individualized fitness program.

The student analyzes the results of fitness assessments to guide changes in a personal fitness program.

The student achieves and maintains appropriate cardiovascular fitness, flexibility, muscular strength, endurance, and body composition.


-Chart paper
-Tape measures


1. Set up chart and markers for discussion.

2. Gather health, fitness, and nutrition magazines, as well as books for reference.


Background Information:
Body composition is the proportion of muscle, bone, fat, and other tissue that make up a person's total weight. Lean body mass is the weight of the body minus the fat. Obesity is excessive body fat. Percent body fat is the percent of fat in the body. Weight maintenance requires that calorie input (food) equals calorie output (exercise). Good nutrition requires eating adequate amounts of protein, carbohydrates, fat, vitamins, minerals, and water. Protein, carbohydrates, and fat are the three nutrients that provide energy.

-Students devise a plan for modifying caloric intake and energy expenditure.
-Students document their caloric intake and energy expenditure over a period of six weeks.
-Students take measurements and record them in their journals on a weekly basis.

Authentic Context:
You notice that your clothes are fitting more tightly lately. When you step on the scale, you notice you’ve put on a few extra pounds. Devise a plan to modify your caloric intake and energy expenditure in order to lose the weight you have gained.

1. Discuss various terms and concepts related to weight management. See Custom 1 Field for background information.

2. With whole group, brainstorm ideas about the relationship between exercising and calories. Record responses on chart paper. Discuss ideas and clarify any misconceptions.

3. In groups of two, or individually, have students devise a plan to modify their caloric intake and energy expenditure. Circulate and provide feedback as students are doing this. Have students record their plans in their journals.

4. In their journals, students will monitor their body composition, caloric intake, and energy expenditure for six weeks. On a weekly basis, students will track
- the total caloric intake from food
- the total amount of energy expenditure and a list of exercises performed

5. Students take the following measurements and record them in their journals:
- upper right arm
- waist
- hips
- upper right thigh
- calf
Students will repeat measurements each week.

6. Collect the journals on a weekly basis. Provide positive feedback and suggestions.

7. At the end of six weeks, students compile a report that includes the criteria listed in the Assessment section.


Suggested Criteria for Report

The report includes
- a plan for modifying caloric intake and energy expenditure
- a rationale or justification for the plan
- beginning and ending body measurements
- a list of caloric intake for each week
- a list of energy expenditure for each week
- a list of activities and exercises that were performed each week
- an explanation or graphic organizer of the relationship between caloric intake and energy expenditure
- personal reflections on progress
- suggestions for ways implementation of the plan could be improved

Self Reflection:
What would I do differently next time I try to lose weight?


Have students follow the plan for a longer period of time in order to see better results.
