Patients who completed an intensive very-low-calorie diet (VLCD) program regained significant weight but maintained over 20% of lost weight long-term. Age positively impacted weight maintenance success in this study.

Area of Science:

  • Obesity research
  • Dietary interventions
  • Metabolic health

Background:

  • Intensive very-low-calorie diets (VLCDs) are used for significant weight loss.
  • Long-term weight maintenance after VLCDs remains a challenge.
  • Understanding factors influencing sustained weight loss is crucial.

Purpose of the Study:

  • To assess the long-term weight maintenance of patients after completing an intensive VLCD program.
  • To identify patterns of weight regain and stabilization post-VLCD.
  • To explore predictors of successful weight maintenance.

Main Methods:

  • Prospective study of patients who completed a 12-week VLCD program and lost at least 10 kg.
  • Follow-up weights collected over 2-7 years via clinic visits and self-report.

  • Statistical analyses, including multiple regression, to determine weight maintenance and influencing factors.

    • Main Results:

    • 112 subjects (72.7%) provided follow-up data after an average of 5.3 years.
    • Average initial BMI was 37.3 kg/m2; average weight loss was 29.7 kg.
    • Subjects regained an average of 73.4% of lost weight within three years, stabilizing thereafter.
    • Average maintained weight loss was 22.8% of initial loss.
    • At 5 years, 40% maintained a 5% weight loss; at 7 years, 25% maintained a 10% weight loss.
    • Older age was significantly associated with better weight maintenance.

    Conclusions:

    • Long-term weight maintenance after intensive VLCD programs shows improvement but requires ongoing intensive support.
    • A substantial percentage of lost weight is typically regained, though stabilization occurs.
    • Age is a positive predictor of successful long-term weight maintenance following VLCD interventions.
