This research aims to find an effective dietary intervention among the Pakistani population. According to WHO, diabetes is on the rise in developing countries; the current prevalence among the Pakistani population is 11.2% which is expected to increase in the coming years which is in line with the similar documented trend in neighboring south Asian countries.3,11 Since, ethnic south Asians carry a greater risk for developing T2D at a younger age and along with the complications associated with diabetes due to its chronicity, this poses a significant threat and an increased disease burden on the health care system.11

This will be the first trial conducted on determining the efficacy of caloric restriction in a subset of Pakistani population. There is limited inconsistent data on the efficacy of time-restricted feeding, however, this will help elucidate if it does lead to positive effects on the bio-health markers. One of the major hurdles in caloric restriction is patient compliance, therefore, one of the intervention group will be used to determine if TRF with caloric restriction helps improve the patient's compliance and produces significant results. If such an intervention is effective in inducing weight loss it can also be applied for other overweight patients. Eventually, it will help in countering the rising obesity in the region.

The ultimate purpose of the knowledge obtained is to find a patient friendly, novel and therapeutic dietary intervention which will help in limiting the rise in T2D patients. It'll help in introducing an effective lifestyle intervention to promote health, which will reduce the dependence on pharmacological therapies, as well as, in the long-term reduce burden on the health care system.

The information obtained can provide framework for new guidelines in helping the patients to lose weight, which can be utilized by the government to increase general awareness which will help prevent diseases linked to obesity. In light of the randomized controlled trial, the primary health physicians can educate and increase awareness regarding the different dietary interventions the patients can utilize which will help increase the number of options for the patients. Social media platforms can be utilized due to their extended outreach for the transmission of accurate information to the general population.
