    Predicting weight loss in obese women is possible using initial weight and adipose cell size. Higher initial adipose cell weight correlated with greater weight loss, while increased fat cell number predicted weight gain.

    Area of Science:

    • Obesity Research
    • Metabolic Studies
    • Nutritional Science

    Background:

    • Obesity is a complex metabolic condition requiring effective weight management strategies.
    • Understanding predictors of weight loss and regain is crucial for long-term treatment success.

    Purpose of the Study:

    • To develop a predictive model for body weight after 6 months of a controlled diet in obese women.
    • To investigate the relationship between initial anthropometric and cellular factors and subsequent weight change patterns.

    Main Methods:

    • Seventy-six obese female outpatients participated in a 1000 kcal controlled diet study.
    • Step-wise multiple regression analysis was used to predict 6-month body weight based on initial parameters.
    • Patients were categorized into weight loss, stable, and gain groups between months 6 and 12.

    Main Results:

    • A linear regression model accurately predicted 6-month body weight (y) using initial weight (x1) and adipose cell weight (x2): y = 9.75 + 0.87x1 - 8.41x2 (R² = 0.95).
    • Patients experiencing weight gain exhibited a significantly higher mean fat cell number.
    • Weight loss participants had a higher mean adipose cell weight compared to stable or weight-gaining groups.

    Conclusions:

    • Initial body weight and adipose cell characteristics are significant predictors of weight loss outcomes in obese women on a controlled diet.
    • Adipose cell size and number play distinct roles in weight maintenance and regain following dietary intervention.
