Key Determinants of Weight Loss Trajectory Across Different Periods of a Behavioral Weight Loss Intervention.

ABSTRACT:

Objective

This longitudinal study aims to identify the key factors influencing the weight loss trajectory during a 24-week intervention and their relevance at different stages of the treatment.

Methods

We studied 1252 participants (age 18-65 years) of a cognitive behavioral program to lose weight. Body weight was measured weekly, and a range of variables at baseline and throughout the treatment period were assessed. Linear regression analyses were conducted to understand the factors involved in the weight loss trajectory across three treatment periods (0-6, 7-12, 13-24 weeks).

Results

The rate of weight loss progressively decreased from the 1st to the 3rd period (770-198 g/week). During the 1st period, the recent history of the individual, including baseline metabolic
