Breakfast Intake and Satiety Hormones

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.

Conditions

• Obesity

Interventions

BEHAVIORAL

Egg Breakfast (EB)

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.

BEHAVIORAL

Cereal Breakfast (CB)

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.

BEHAVIORAL

Weight Loss Counseling

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.

BEHAVIORAL

Weight Loss Diet

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