NCT00622050

Brief Summary

The specific objectives of this project are to:

  1. 1.Investigate the effects of reducing TV viewing time on energy intake, eating behavior, and energy expenditure in overweight or obese adult subjects, thus providing a basis for evaluating if reducing TV viewing time might be a useful adjunct therapy in obesity prevention and treatment
  2. 2.Analyze the types of foods eaten in conjunction with TV viewing
  3. 3.Determine if there is an association between location of TV and BMI.

Study Arms (2)

1

EXPERIMENTAL

This arm will be experiencing the same protocol as the control group, only their TV viewing time will be reduced. The TV viewing time reduction is the experimental intervention.

Behavioral: TV viewing reduction

Control

ACTIVE COMPARATOR

The control group will be experiencing the exact protocol; only their TV viewing time will not be reduced.

Behavioral: No TV viewing reduction

Interventions

No TV viewing reductionBEHAVIORAL

In the control group, no intervention will be acted upon. This group will receive the exact same protocol as the intervention group, but with observation only.

Control
TV viewing reductionBEHAVIORAL

In the experimental arm, TV viewing time will be reduced for half of the study protocol time (3-4 weeks of a 6-8 week protocol).
