Ehdot
Yksityiskohtainen kuvaus
This will be a crossover study with 2 experiments. Subjects will follow a reduced energy weight loss diet of 1,200-1,500 kcal adjusted to each individual's body weight for totally 2 weeks in each experiment. They will come to the clinic from day 1 to day 7 and consume egg breakfast (EB) for 5 days under our supervision. Then on weekends during this period they will continue this breakfast at home based on our advice. The next week they will have cereal breakfast (CB) and the process is similar to that in the first week.
The 1st experiment will test the satiety from egg breakfast (EB) and following energy intake in both lunch and dinner, compared with CB (cereal breakfast). Lunch and dinner will be offered on 2 test days during each week. Anthropometric and body composition measurements, blood pressure, blood draw, satiety questionnaire, as well as energy intake will also be collected in the 2 test days and compared between 2 breakfast groups.
The 2nd one is to test whether EB will help in resisting the intake of foods considered tempting, but detrimental to weight loss efforts, compared with CB. The process is similar to experiment 1 except no blood draw, no dinner offered. Instead, a tempting food after lunch will be offered.

Kokeellinen: Egg Breakfast (EB)
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. |
Breakfast is considered as high quality protein diet, but has similar weight, energy, and macronutrients as the active comparator.
The details are as follows: weight 291 g,energy 400 kcal, energy density 1.37 kcal/g, carbohydrate 42.9%, fat 35.6%, protein 19.8%, protein digestibility corrected amino acid score (PDCAAS) 100, leucine 1.77 g, glycemic load 24, fiber 1.0 g.
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 will include portion control, macronutrient distribution, snacking, eating out, cooking and grocery shopping, as well as behavioral strategies including self-monitoring, motivational interviewing, goal setting, and problem solving.
Participants will have a 1200-1500kcals diet based on each individual's body weight during the study.

Active Comparator: Cereal Breakfast (CB)
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. |
