Study summary

The first goal of the proposed study is to determine acute and long-term effects of mixed nuts (almonds, hazelnuts, pecans, pistachios, walnuts, and peanuts) on metabolic parameters and weight management. While numerous studies have shown the beneficial effects of nuts on promoting negative energy balance and weight loss, mechanistic studies exploring how the inclusion of nuts in the diet promotes a negative energy balance and weight loss have not been conducted. The second goal is to determine the mechanisms by which mixed nut consumption regulates of food intake and body weight.

What researchers measure

Primary outcomes

  1. Change of Satiety

    Hunger feeling (appetite) will be examined using visual analog scale (0-10): 0 least and 10 greatest

    Time frame: 0, 20, 40, 60, 90 and 120 minutes post snack consumption

  2. Change of glucose level

    Glucose level will be examined using glucose analysis

    Time frame: Baseline, 40 minutes post snack consumption, and 8 weeks and 16 weeks post daily consumption

  3. Change of insulin level

    Insulin level will be examined using an ELISA biochemical method

    Time frame: Baseline, 40 minutes post snack consumption, and 8 weeks and 16 weeks post daily consumption

  4. Change of cholesterol levels

    Cholesterol levels will be examined using a biochemical method

    Time frame: 8 weeks and 16 weeks post daily consumption

  5. Change of Lp(a)

    Lp(a) levels will be examined using an ELISA biochemical method

    Time frame: 8 weeks and 16 weeks post daily consumption

Secondary outcomes

  1. Change of microbiome

    Diversity of microbiome will be analyzed in fecal samples

    Time frame: 8 weeks and 16 weeks post daily consumption
