Impact of providing walnut samples in a lifestyle intervention for weight loss: a secondary analysis of the HealthTrack trial

Journal Article


Abstract


  • Background: Being more specific about individual food choices may be advantageous for weight

    loss. Including a healthy food (e.g. walnuts) may help to expose effects.

    Objective: To examine the impact of including walnuts in diets for weight loss.

    Design: Secondary analysis of the HealthTrack lifestyle intervention trial. Overweight and obese

    participants were randomized to: usual care (C), interdisciplinary intervention including individualized

    dietary advice (I), or interdisciplinary intervention including 30 g walnuts/day (IW).

    Changes in body weight, energy intake, intake of key foods, physical activity, and mental health

    over three and 12 months were explored.

    Results: A total of 293 participants completed the intensive three-month study period, and 175

    had data available at 12 months. The IW group achieved the greatest weight loss at three

    months. IW reported significant improvements in healthy food choices, and decreased intakes

    of discretionary foods/beverages, compared to C. Weight loss remained greatest in IW at 12

    months.

    Discussion: Significant effects were seen after three months, with the IW group achieving greater

    weight loss and more favorable changes in food choices.

    Conclusions: Including 30 grams walnuts/day in an individualized diet produced weight loss and

    positive changes in food choice.
