简要总结
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.
详细描述
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.

盲法说明
Participants will not be blinded, as they will be instructed to perform the intervention in the control of meal time. This is a limitation of the study design, however, it is expected to minimize the bias by not explaining to the participants what is expected by the intervention of the research. The researcher, who will measure the outcomes, will not know to which group the individual belongs.
