Patterns of Weight Change in a Commercial Weight Loss Program

Area of Science:

• Obesity research
• Behavioral science
• Health outcomes

Background:

• Weight management programs aim to help individuals achieve and maintain a healthy weight.
• Understanding factors influencing weight loss success and long-term maintenance is crucial for public health.
• Individual variability in weight loss trajectories necessitates the study of distinct weight change patterns.

Purpose of the Study:

• To investigate factors associated with weight loss and maintenance in a commercial program.
• To identify and characterize individual patterns of weight change following an initial weight loss period.
• To determine the impact of early weight loss achievement on longer-term weight management outcomes.

Main Methods:

• Secondary analysis of pre-post data from 8769 participants in a commercial weight management program.
• Multiple regression analyses were used to assess the association between program engagement and weight change.
• ANOVA and Pearson chi-square tests were employed to identify distinct weight change patterns and participant characteristics.

Main Results:

• Participants lost an average of 8.53 kg (-8.61%), with greater loss linked to higher appointment frequency and spending.
• Five distinct weight change patterns were identified, ranging from stable loss to significant regain.
• Achieving early weight loss (>5% in 2 months) was significantly associated with greater final weight loss.

Conclusions:

• Weight management success is influenced by program engagement, particularly health coaching attendance.
• Recognizing and understanding different weight change patterns can inform personalized weight management strategies.
• Early success in weight loss is a strong predictor of better long-term weight management outcomes.
