Approaches to
Weight Loss
• Low Calorie Diet
• Track eating, and reduce portion size and/or ingredients
to limit calories
• Meal Replacement
• Replace one or two meals with low calorie options
• If the total calorie of the plans are equivalent, results
should be similar, but…

Self-monitoring
• All behavior regulation begins with self-monitoring
• Do we actively avoid monitoring?
• Is food set-up not to monitor?
• People eat as much as in on their plate
• People eat more as food is easier to reach (M&M’s)
• Meal replacement simplifies monitoring
• Are we monitoring the right factor?
• Eating behavior
• Weight loss
• How we look in a black dress

Comparisons
• Behavior cannot be understood without consideration
to some standard
• What is our standard?
• Magazine cover models
• Friends and co-workers
• High school weight
• How easy is to compare?
• Tracking calories vs did I eat more than my replacement
meal?

Affective Response
• Successful comparison leads to positive feelings
• This provides motivation to continue
• Failure to meet standard leads to negative feelings
• This provides motivation to change
• Speed with which we move toward or away dictates the strength of
those feelings
• How fast do I expect?
• Challenges:
• Behavior can lead to negative feelings
• Does the replacement taste good?
• Am I embarrassed to eat a salad at work?
• Am I eating enough not to feel hungry?
• Can result in excessive negative feelings and reproach
• Respond with a vow to never diet again!

Behavior Change
• We respond with a change in behavior so as to reduce
the negative mood
• We continue the behavior to maintain a positive mood
• This is independent of our goal
• There are other ways to modify mood
• The behavior we change depends upon the what we
are monitoring
• Can we just dress better?
What is our motivation?
What do we monitor?

We must establish complimentary goals to keep this spinning

Norms
Competing or
Complimentary goals
• Goals are established and monitored to compliment
the primary source of motivation
• Diet and exercise are monitored to support weight loss
• Meals are replaced to reduce calories
• Other goals exist that may compete with the primary
source of motivation
• How do I want to be perceived at a party?
• How much do the replacement meals cost?
• If we are aware of these interaction we are better able
to regulate
Take Home
• If you want to change a behavior
• Focus on behaviors that can be monitored and maintained
• Select an accurate standard for comparison
• Recognize that change is slow
• Who is happy losing 12lbs in a 6 weeks?
• Stay focused on your ultimate goal – not the frustration that
you will feel from time to time
• Do not let one loss turn into two
