  • Protocol summary

    The aim of present study is to compare the effects of high protein versus high carbohydrate intake at evening meal on glycemic control, lipid profile and oxidative stress in patients with type 2 diabetes. This study is a randomized controlled trial (parallel design) with study duration of 10 weeks. One hundred and thirty five patients with type 2 diabetes mellitus who have hemoglobin A1c (HbA1c) less than or equal to 8% and do not take insulin or α glucosidase inhibitors will be recruited by convenience sampling. Then they will be randomly assigned into three groups of “standard evening meal”, “high protein evening meal” and “high carbohydrate evening meal” and receive their respective diets. In “standard evening meal” group; carbohydrate, protein and fat have a balanced distribution among meals while in “high carbohydrate evening meal” group 40-45% of daily carbohydrate intake and in “high protein evening meal” group, 40-45% of daily protein intake will be allocated to evening meal and bedtime snack. Participants with poor dietary adherence will be excluded from the study. Body weight and waist circumference will be measured before the intervention, at week 5 and at the end of the intervention. Furthermore fasting glucose, HbA1c, insulin, lipid profile and oxidative stress will be measured at the beginning and at the end of the intervention. Fasting glucose will be also measured at weeks 2 and 5.

    هدف از انجام این مطالعه مقایسه اثر مصرف بالای پروتئین با کربوهیدرات در وعده شام بر کنترل گلیسمک، پروفایل لیپیدی و استرس اکسیداتیو در بیماران مبتلا به دیابت نوع 2 می باشد. این مطالعه یک کار¬آزمایی کنترل شده تصادفی از نوع موازی با طول مدت مداخله 10 هفته می باشد. 135 فرد مبتلا به دیابت نوع 2 که هموگلوبین ای وان سی (HbA1c) کم تر مساوی 8 درصد داشته و انسولین و داروهای مهار کننده آلفا گلوکوزیداز مصرف نمی کنند بر اساس نمونه گیری آسان انتخاب خواهند گردید. سپس افراد به صورت تصادفی به 3 گروه دریافت کننده وعده شام استاندارد، با پروتئین بالا و با کربوهیدرات بالا تقسیم بندی می شوند و به هر یک از آن ها یک رژیم غذایی داده خواهد شد. در رژیم گروه دریافت کننده شام استاندارد؛ کربوهیدرات، پروتئین و چربی به میزان متعادلی بین وعده های غذایی توزیع خواهند شد در صورتی که در رژیم گروه دریافت کننده شام با پروتئین بالا، %45-40 پروتئین دریافتی روزانه و در گروه دریافت کننده شام با کربوهیدرات بالا، %45-40 کربوهیدرات دریافتی روزانه در وعده شام و میان وعده آخر شب گنجانده خواهند شد. افرادی که پایبندی ضعیفی به رژیم غذایی مربوطه داشته باشند از مطالعه خارج خواهند گردید. وزن بدن و دور کمر، قبل از مداخله، هفته 5 و بعد از مداخله اندازه گیری می گردند. قند ناشتا، HbA1c، انسولین، پروفایل لیپیدی و استرس اکسیداتیو نیز در ابتدا و انتهای مداخله اندازه گیری می شوند. قند ناشتا در هفته 2 و 5 نیز اندازه گیری خواهد شد.

    This is a 10-week single blinded, randomized controlled trial. Applying block randomization, the participants will randomly assigned to either of the following three groups: Standard evening meal, High carbohydrate evening meal and High protein evening meal. Sample size was calculated to be 30 in each group.

    The Participants will be followed for 10 weeks, during which they visit the specially designated clinic in Shiraz city at weeks 2, 5 and 10.Body weight and waist circumference will be measured before the intervention, at week 5 and at the end of the intervention. Furthermore fasting glucose, HbA1c, insulin, lipid profile and oxidative stress will be measured at the beginning and at the end of the intervention. Fasting glucose will be also measured at week 5. Participants will be unaware of random allocation into different groups.

Protocol summary

Study aim
The aim of present study is to compare the effects of high protein versus high carbohydrate intake at evening meal on glycemic control, lipid profile and oxidative stress in patients with type 2 diabetes.
Design
This is a 10-week single blinded, randomized controlled trial. Applying block randomization, the participants will randomly assigned to either of the following three groups: Standard evening meal, High carbohydrate evening meal and High protein evening meal. Sample size was calculated to be 30 in each group.
Settings and conduct
The Participants will be followed for 10 weeks, during which they visit the specially designated clinic in Shiraz city at weeks 2, 5 and 10.Body weight and waist circumference will be measured before the intervention, at week 5 and at the end of the intervention. Furthermore fasting glucose, HbA1c, insulin, lipid profile and oxidative stress will be measured at the beginning and at the end of the intervention. Fasting glucose will be also measured at week 5. Participants will be unaware of random allocation into different groups.
Participants/Inclusion and exclusion criteria
Inclusion criteria are having type 2 diabetes; diabetes duration of 1-15 years; age of 30-65 years old; HbA1c ≤ 8%; BMI 22-35 Kg/m2; not taking insulin or α glucosidase inhibitors; weight maintenance during past 3 month; not having heart, liver, kidney, thyroid, gastrointestinal and respiratory disorders or malignancies; not consuming alcohol; not being on special diets like vegan; not being pregnant or lactating.
Intervention groups
In Standard evening group, protein and carbohydrate are rather evenly distributed among meals. In High carbohydrate evening meal group, 40-45% of total carbohydrate intake is provided at dinner and evening snack. In High protein evening meal group, 40-45% of total protein intake is at dinner and evening snack.
