About this study

Official title: Does Higher Protein Quality Reduce Energy Intake When Following a Weight Loss Diet Plan? -- Nonpilot, Powered Crossover

The purpose of this study is to determine if, in presence of a reduced calorie diet, a breakfast containing high quality protein source (eggs) would be more effective in reducing hunger and increasing feeling of fullness compared to a breakfast containing a lower quality of protein, but equal energy density. A previous pilot study with the same endpoints yielded borderline significant results; this study has been powered based on that pilot to interrogate our hypotheses.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Egg breakfast (EB)Behavioural

    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 CounselingBehavioural

    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.

  • Weight Loss DietBehavioural

    Participants will have a 1200-1500kcals diet based on each individual's body weight during the study.

  • Cereal Breakfast (CB)Behavioural

    Breakfast is considered as low quality protein diet, but has similar weight, energy, and macronutrients as that in experimental group. The details are as follows: weight 293 g, energy 398 kcal, energy density 1.36 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

    This will be measured by questionnaire (VAS) and compared the changes between 2 test days (day 7 and day 14) in experiment 1\&2

    Measured: Change in scores (arbitrary units AUC) from 30 minutes before breakfast consumption to 240 minutes after the consumption on day 7 and day 14

  2. Change of objective satiety

    It is measured by GLP-1. This will be tested in experiment 1 and changes will be compared between 2 test days.

    Measured: Change in concentration (AUC) from 30 minutes before breakfast consumption to 180 minutes after the consumption on day 7 and day 14

  3. Change of objective satiety

    It is measured by PYY 3-36. This will be tested in experiment 1 and changes will be compared between 2 test days.

    Measured: Change in concentration (AUC) from 30 minutes before breakfast consumption to 180 minutes after the consumption on day 7 and day 14.

    Measured: Change in concentration (AUC) from 30 minutes before breakfast consumption to 180 minutes after the consumption on day 7 and day 14.

  5. Other change of hormone level

    It is measured by serum glucose. This will be tested in experiment 1 and changes will be compared between 2 test days.

    Measured: Change in concentration (AUC) from 30 minutes before breakfast consumption to 180 minutes after the consumption on day 7 and day 14.

  6. Other change of hormone level

    It is measured insulin levels. This will be tested in experiment 1 and changes will be compared between 2 test days.

    Measured: Change in concentration (AUC) from 30 minutes before breakfast consumption to 180 minutes after the consumption on day 7 and day 14.

  7. Energy intake (kcal) during ad libitum lunch

    Energy intake will be compared between 2 test days in experiment 1

    Measured: Test day 7 and day 14

  8. Energy intake (kcal) during ad libitum dinner

    Energy intake will be compared between 2 test days in experiment 1

    Measured: Test day 7 and day 14

  9. Energy intake (kcal) during ad libitum lunch

    Chocolate brownies will be added to the test lunch. Energy intake will be compared between 2 test days in experiment 2

    Measured: Test day 7 and day 14

Secondary outcomes (6)
  1. Change in body weight (kg)

    Body weight change from baseline to day 7, and change from day 7 to day 14 will be compared

    Measured: Day 0, day 7 and day 14

  2. Change in waist and hip circumference (cm)

    Waist and hip circumference change from baseline to day 7, and change from day 7 to day 14 will be compared

    Measured: Day 0, day 7 and day 14

  3. Change in blood pressure (mm Hg)

    BP change from baseline to day 7, and change from day 7 to day 14 will be compared

    Measured: Day 0, day 7 and day 14

  4. Change in fat mass and lean body mass percentage
