Effects of the Administered Time of Meal on the Treatment of Overweight and Obesity

Clinical Study Randomized of the Effects of the Administered Time of Meal on the Treatment of Overweight and Obesity

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 110 (estimated)
• Sponsor: Hospital de Clinicas de Porto Alegre · Academic / Other
• Sex: All
• Age: 20 Years – 59 Years
• Healthy volunteers: Not accepted

Summary

Objectives: To evaluate the impact of the meal time administered on the body weight of adult individuals of both sexes, being overweight and obese. Experimental design: randomized controlled trial. Place of research: Hospital de Clínicas de Porto Alegre, Porto Alegre, RS, Brazil. Materials and methods: Anthropometric data, blood pressure, waist diameter will be measured; venous blood samples will be collected and stored for glucose, total cholesterol, triglycerides, HDL-cholesterol, urea, creatinine and ALT in serum. Intervention: Wait at least 20 minutes after finishing the first portion of meals, previously considered sufficient by the individual before serving again. The control group will also serve the dish the same way, but you can serve additional portion without waiting. Measurements: P values less than 0.05 will be considered statistically significant. Expected results: Weight loss, decrease in anthropometric markers and risk factors for cardiovascular diseases.

Detailed description

Introduction: The increasing rates of overweight and obesity in the world population have worried health professionals about their quality and life expectancy. Intervention methods such as weight management programs can promote eating behaviors more suited to the energy needs of these individuals. Objectives: To evaluate the impact of the meal time administered on the body weight of adult individuals of both sexes, overweight and obese. Experimental design: randomized controlled trial. Place of research: Hospital de Clínicas de Porto Alegre, Porto Alegre, RS, Brazil. Participants: Adults of both sexes. Materials and methods: Individuals will be invited to participate and will receive a free and informed consent form. If they agree, anthropometric data, blood pressure, waist diameter will be measured; venous blood samples will be collected and stored for glucose, total cholesterol, triglycerides, HDL-cholesterol, urea, creatinine and ALT in serum. Intervention: Wait at least 20 minutes after finishing the first portion of meals, previously considered sufficient by the individual before serving again. The control group will also serve the dish the same way, but you can serve additional portion without waiting. Measurements: The Kolmogorov-Smirnoff tests will be used to evaluate the distribution of continuous variables, and Student's t test, Mann-Whitney, and chi-square test, when appropriate. Values of p less than 0.05 will be considered statistically significant. Expected results: Adults randomized to receive the intervention will gain weight loss, decrease in anthropometric markers and risk factors for cardiovascular diseases. Project cost / benefit: Low cost and risk study that will contribute to the development of actions and programs related to the reduction of risk factors due to overweight and disease prevention.
