Dairy Consumption for Weight Management
Trial Summary
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify whether you need to stop taking your current medications. However, if you are using any prescription or non-prescription drugs, herbal or nutritional supplements that might affect the study's outcome, you may be excluded from participating.
What data supports the effectiveness of the treatment Increasing Dairy intake for weight management?
Research suggests that consuming dairy foods may help with weight management, especially when combined with a moderate calorie-restricted diet. Studies indicate that higher dairy intake is linked to increased weight loss and maintenance of lean body tissue, possibly due to effects on fat breakdown and appetite regulation.12345
Is increasing dairy intake safe for weight management in humans?
Research on dairy consumption for weight management shows it is generally safe for humans, with studies indicating no significant adverse effects on body weight or fat gain. However, the effectiveness of dairy for weight management varies, and more research is needed to understand its full impact.12678
How does increasing dairy intake differ from other treatments for weight management?
Increasing dairy intake is unique because it focuses on incorporating more dairy foods into the diet, which may help with weight management by promoting fat loss and maintaining lean muscle during calorie restriction. This approach leverages the potential benefits of dairy components like calcium and whey protein, which may influence appetite regulation and fat metabolism, unlike other treatments that might focus solely on calorie reduction or exercise.127910
What is the purpose of this trial?
The goal of this study is to examine how regular dairy intake affects body weight, body composition, and metabolic health in overweight and prediabetic adolescents (ages 14-17) and older adults (ages 60-75) over a six-month period. We are inviting eligible individuals to participate in this study at the Nutrition Intervention Center, Department of Nutritional Sciences, University of Toronto, St. George campus. Participants will be randomly divided into two groups. The intervention (high-dairy) group will consume three servings of dairy per day (milk, yogurt, and cheese) before breakfast, lunch, and dinner. The control (low-dairy) group will continue their usual diet, keeping dairy intake less than one serving per day.Participants will have biweekly sessions with a registered dietitian to monitor their dietary intake and ensure compliance with their assigned group. In addition, they will visit the Nutrition Intervention Center at week 0, week 12, and week 24 for anthropometric and body composition assessments (weight, height, waist circumference, blood pressure, lean mass, fat mass), glycemic and metabolic markers (fasting blood glucose, insulin, HbA1c, lipid profiles in seniors, and appetite hormones in adolescents). Each assessment visit will take approximately 4 hours.Before each visit, you will be asked to fast for 12 hours overnight, maintain your usual diet and sleep patterns, and avoid exercise and alcohol consumption the day before. Your participation in this study will help us better understand the role of dairy in metabolic health and may contribute to improved dietary recommendations for adolescents and older adults. You will be compensated for your time and travel expenses.
