Satiety
Conditions
Brief 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.
Interventions
