A study testing water with glucose, water and whey protein and water with noncaloric sweetener in people with Obesity, run by University of Toronto at 1 site in Canada.
Trial summary
The investigators hypothesize that glucose and whey protein given 30 and 60 min before a pizza meal will exert different effects on food intake in adolescent children, and will depend on pubertal stage. Read more about this study

About this study
Official title: The Effect of Glucose, Whey Protein and Time to the Next Meal on Food Intake and Subjective Appetite in Normal Weight and Overweight/Obese Children
The investigators hypothesize that glucose and whey protein given 30 and 60 min before a pizza meal will exert different effects on food intake in adolescent children, and will depend on pubertal stage. Food intake will be measured at 30 and 60 min following a glucose(0.75 g of glucose/kg body weight), whey protein (0.75 g of glucose/kg body weight) or sweetened noncaloric beverage. Subjective appetite will be measured as well.

Food intake will be measured at 30 and 60 min following a glucose(0.75 g of glucose/kg body weight), whey protein (0.75 g of glucose/kg body weight) or sweetened noncaloric beverage.

Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Food intake (kcal) (time frame: 30 and 60 min after the treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
