Prevalence of type 2 diabetes mellitus has been increasing at an alarming level with nearly 101 million Indians living with diabetes in India as per latest ICMR-INDIAB report. With such a high incidence, only 7.7% of individuals with diabetes are found to achieve all three ABC target (HbA1c, blood pressure and LDL- cholesterol levels). This indicates that achievement of targets and adoption of healthy behaviors remains sub-optimal in India. 

In people with T2DM, blood glucose levels are usually higher in the morning than at other times of the day. Additionally, commonly consumed breakfast items in India like upma and poha are rich in simple carbohydrates and lack protein and fiber.

In a high carbohydrate consuming nation like India, meeting dietary protein requirements can be a challenge especially for vegetarians.

Increasing intake of dals/pulses in a vegetarian diet may not be an effective solution as a lot of people experience bloating and gas. Dairy products are also advised to be consumed in moderation since they are rich in calories and saturated fat. Even non-vegetarians struggle to meet their requirement as the consumption is strongly influenced by religion and cultural practices and so the frequency of consumption may not be sufficient enough to meet the daily protein requirements. To bridge this gap between the intake and requirement, Diabetes Specific Protein Supplement (DSPS) can be useful if dietary sources are not sufficient.

This study therefore aims to assess whether the post meal glycemic response with partial meal replacement using DSPS at breakfast is lower compared to an isocaloric control breakfast in individuals with type 2 diabetes mellitus.
