Talk to General Physician on Diabetes/Heart Disease

My parents in law both have health problems and both have now had a triple bypass for their heart. Are there any businesses in Lahore that supply pre packaged meals for special diets where we could order for a week & have it delivered. As all the kids live outside, we know they will continue to cook unhealthy food (laden with salt and unbalanced carbs) and buy high cholesterol food from the bazaar.
