NCT02497859

Brief Summary

The experiments in this study will assess if while following a reduced energy diet, eating a breakfast with higher protein quality will enhance weight loss compared to another breakfast with lower protein quality, but matched for energy density and macronutrient composition.

Outcome Measures

Primary Outcomes (8)

  • Change in subjective hunger questionnaire (Visual Analog Scale)

    Change in scores (arbitrary units AU) from 30 minutes prior to breakfast consumption to 240 minutes post consumption.

  • Change in serum satiety and hunger hormones

    Concentrations of ghrelin, GLP1, PYY 3-36, insulin, and serum glucose will be determined. This is only for experiment 1.

    Change (AU) from 30 minutes prior to breakfast consumption to 240 minutes post consumption.

  • Energy intake (kcal) during ad libitum lunch

    This is for experiment 1.

    Test day 7 (30 minutes for buffet).

  • Energy intake (kcal) during ad libitum lunch

    This is for experiment 1.

    Test day 14 (30 minutes for buffet).

  • Energy intake (kcal) during ad libitum dinner

    This is for experiment 1.

    Test day 7 (30 minutes for buffet).

  • Energy intake (kcal) during ad libitum dinner

    This is for experiment 1.

    Test day 14 (30 minutes for buffet).

  • Energy intake (kcal) during ad libitum lunch

    This is for experiment 2. Chocolate brownies will be added to the test lunch.

    Test day 7 (30 minutes for buffet).

  • Energy intake (kcal) during ad libitum lunch

    This is for experiment 2. Chocolate brownies will be added to the test lunch.

    Test day 14 (30 minutes for buffet).

Secondary Outcomes (7)

  • Change in body weight in kilograms

    Change in kilograms from baseline to test day 7.

  • Change in body weight in kilograms

    Change in kilograms from test day 7 to test day 14.

  • Change in waist and hip circumference in centimeters

    Change in centimeters from baseline to test day 7.

  • Change in waist and hip circumference in centimeters

    Change in centimeters from test day 7 to test day 14.

  • Change in blood pressure (mm Hg)

    Change in mm Hg from baseline to test day 7.

  • +2 more secondary outcomes

Study Arms (2)

Egg Breakfast (EB)

EXPERIMENTAL

The EB will receive the following breakfast: 2 scrambled eggs, 120 mL skim milk, 2 slices of Mrs. Bairds® Extra Thin White Bread, 5 g of butter, and 18 g of Smuckers® Strawberry Jam.

Behavioral: Egg Breakfast (EB)Behavioral: Weight Loss CounselingBehavioral: Weight Loss Diet

Cereal Breakfast (CB)

ACTIVE COMPARATOR

The CB will receive the following breakfast: 1.5 cups of Special K® Ready-to-Eat Original Cereal, 200 ml Silk® Original Soymilk, 1 slice of Nature's Own® Double Fiber Wheat Bread, 13 g of butter, and 10 g of Smuckers® Sugar-Free Strawberry Jam.

Behavioral: Cereal Breakfast (CB)Behavioral: Weight Loss CounselingBehavioral: Weight Loss Diet

Interventions

The EB will receive a breakfast of higher quality protein, but similar in macronutrient and energy density than the active comparator. The EB will have the following energy density, macronutrient composition, and protein score: weight 291 g,energy 400 kcal, energy density 1.37 kcal/g, carbohydrate 42.9%, fat 35.5%, protein 19.8%, protein digestibility corrected amino acid score (PDCAAS) 100, leucine 1.77 g, glycemic load 24, fiber 1.0 g.

Egg Breakfast (EB)

The CB will receive a breakfast of lower quality protein, but similar in macronutrient and energy density than the experimental treatment. The CB will have the following energy density, macronutrient composition, and protein score: weight 293 g, energy 398 kcal, energy density 1.3 kcal/g, carbohydrate 44.8%, fat 35.4%, protein 19.8%, protein digestibility corrected amino acid score (PDCAAS) 42, leucine 0.48 g, glycemic load 30.8, fiber 4.4 g.

Cereal Breakfast (CB)

Weight loss counseling will be administered by a Registered Dietitian and will utilize information and materials derived from the Evidence Analysis Library (EAL) of the Academy of Nutrition and Dietetics (AND). Topics including portion control, macronutrient distribution, snacking, eating out, cooking and grocery shopping, will be discussed. Self-monitoring, motivational interviewing, goal setting, and problem solving will be the behavioral strategies used during counseling.

Cereal Breakfast (CB)Egg Breakfast (EB)

Energy intake for study duration will be prescribed at 1,200-1,500 kcals adjusted for each individual's body weight.
