Area of Science:

  • Nutrition and Dietetics
  • Public Health
  • Behavioral Science

Background:

  • Weight control is a significant concern for U.S. adults, with substantial spending on related products and services.
  • National data on specific weight management practices are limited.
  • This study examines weight-loss and weight-maintenance behaviors in a representative U.S. adult population.

Purpose of the Study:

  • To describe the prevalence of weight control attempts among U.S. adults.
  • To identify specific weight-loss and weight-maintenance practices employed by U.S. adults.
  • To assess the alignment of these practices with recommended guidelines.

Main Methods:

  • Analysis of data from the 2001-2002 National Health and Nutrition Examination Survey (NHANES).

  • Inclusion of a nationally representative sample of U.S. adults aged 20 years and older (n=5027).
  • Focus on individuals who attempted to lose weight or maintain weight in the preceding 12 months.

    • Main Results:

    • Over half of U.S. adults (51%) attempted weight control in the past year.
    • Primary methods included reducing food intake (65% for weight loss, 52% for maintenance), exercising (61% vs. 46%), reducing fat intake (46% vs. 42%), and choosing lower-calorie foods (37% vs. 36%).
    • Fewer than 25% of adults combined caloric restriction with the recommended 300+ minutes of weekly physical activity.

    Conclusions:

    • Weight control is a widespread goal among U.S. adults.
    • Current weight management strategies often lack the recommended integration of dietary changes and sufficient physical activity.
    • There is a gap between common weight control practices and evidence-based recommendations.
