简要总结
Proposed is a parallel-design randomized controlled trial to compare the effects of consuming two types of snacks on a daily basis for a 12-week period on health outcomes, diet quality, and self-reported satiety in a group of overweight adults. The types of snacks to be studied are KIND snack bars with almonds and typical American snack foods).
详细描述
Snacking has been implicated in the obesity epidemic, but judicious snacking can help control appetite and calorie intake and add nutrient-dense foods to the diet. The investigators hypothesize that snacking on nutrient-dense, highly satiating snack foods (i.e. KIND snacks with almonds) as compared to snacking on nutrient-dilute, energy-dense foods (i.e., conventional snack foods) will contribute to satiety, weight loss, and health improvements. The investigators further hypothesize that the benefits of healthful snacking are enhanced when portion is clearly defined and controlled by packaging. Finally, the investigators hypothesize that these effects will be seen even when study participants are given clear guidance about the calorie content of snack items, and how to make room for those calories in their diets.
Hypotheses:
- Snacking on nutrient-dense, highly satiating snack foods (i.e. KIND snacks with almonds) as compared to snacking on nutrient-dilute, energy-dense foods (i.e., conventional snack foods) will contribute to satiety, weight loss, and health improvements.
- The benefits of healthful snacking are enhanced when portion size is clearly defined and controlled by packaging.
- These effects will be seen even when study participants are given clear guidance about the calorie content of snack items, and how to make room for those calories in their diets.

研究组 & 干预措施
KIND Bar
Daily inclusion of KIND Bars with almonds as a primary ingredient as part of the participant's usual diet, with diet counseling to adjust for the calories from the KIND Bars. KIND Bars that we will use in the study will include: Dark Chocolate Chili Almond; Cranberry Almond; Almond Walnut Macadamia; Pomegranate Blueberry Pistachio; Nut Delight; Fruit and Nut Delight; Almond and Apricot; Blueberry Pecan and Fiber.
干预措施: KIND Bars (Dietary Supplement)
Typical American Snack
Daily inclusion of conventional snacks (as part of the participant's usual diet, with diet counseling to adjust for the calories from the snacks. The snacks will consist of cookies considered to be conventional snack foods that are nutrient-dilute (i.e. relatively low in nutrients) and energy-dense (i.e., relatively high in kcal). Examples of conventional snack foods will include: Nabisco Snackwell Creme Sandwich 1.7 oz pack, Nabisco Newtons Fig 2 oz pack, Nabisco Cips Ahoy! Chocolate Chip 1.4 oz pack, and Nabisco Oreo Double Stuff Chocolate 1.3 oz pack.
干预措施: Typical American Snack (Dietary Supplement)
