4 Clinical Trials for Various Conditions
The purpose of this study is to test the hypothesis that the disruption of the "normal" (three meals a day) eating pattern and prolonged overnight fasting caused by skipping breakfast: i) alters the expression of specific clock genes and clock gene targets involved in regulating adipose tissue lipolysis (breakdown or destruction); ii) increases basal adipose tissue lipolytic (breakdown) activity and plasma free fatty acid (FFA) concentrations; iii) reduces skeletal muscle insulin sensitivity; and iv) increases daylong plasma glucose, FFA, and insulin concentrations. The investigator will do this by studying healthy, lean persons either randomized to consume either 3 standard meals per day or omit breakfast and consume 2 meals per day without changing daily calorie intake (skipping breakfast group).
75 overweight, habitual 'breakfast-skipping' adolescents will complete the following long-term, randomized controlled trial. Participants will be randomly assigned to the following breakfast treatments: 350 kcal high protein breakfasts containing 30 g protein (primarily from lean beef), 35 g carbohydrates, and 10 g fat; 350 kcal normal protein breakfasts containing 10 g protein, 55 g carbohydrates, and 10 g fat; or will continue to skip breakfast. The following outcomes will be assessed during baseline and 4-month (post-intervention): body weight \& body composition; waist circumference; daily food intake; 24-h free-living glycemic control; and pre and post-prandial satiety. In addition, body weight and free-living breakfast intake (quantity, quality, and type) will also be assessed at 2-month follow-up
The purpose of this study is to examine the effects of breakfast skipping (SKIP) vs. the consumption of a high protein solid (HP-S) breakfast vs. the consumption of a high protein beverage (HP-B) breakfast on daily appetite control, food cravings, food intake, and sleep quality in young adults.
The purpose of this study is to assess whether the daily addition of a protein-rich breakfast leads to beneficial changes in appetite control, food intake regulation,and cognitive function in overweight \& obese 'breakfast skipping' young women.
