AbstractCounseling efforts to improve self management are dominant components of any effective treatment plan. For people with diabetes mellitus to achieve optimal glycaemic control, motivation to perform self management like dietary and lifestyle related aspects is important. The researcher has determined whether or not counseling based interventions are clinically effective for improving glycaemic control of type 2 Diabetes Mellitus. The studies have been included research papers were based on dietary counseling based intervention. The current study has included 23 Randomized Control Trials (RTCs), while 16 were group based approaches while 7 were individual based approaches. All trials were effective in improving glycaemic control and reported statistically significant improvements in glycated hemoglobin test (HbA1c) levels through diet counseling based intervention. Regarding the counseling method, individualized counseling was more effective. Combining diet, exercise, and psychosocial intervention is more effective than dietary counseling alone. Studies have shown that a repetitive and long term dietary counseling intervention that offers follow up management was more effective than a short term counseling intervention.
