Though all three – Food Pyramid, MyPlate, and MyThali are based on NIN (National Institute of Nutrition) guidelines, the difference between each is how and what they represent.
The Food Pyramid and MyPlate show you the portions of each food group in their raw form that you need to consume every day. While MyThali portions out all your meals by dividing each food group in fixed cooked quantities.
Taking away the confusion in planning your meals, the MyThali meal plans show you the right portions of all your food groups for each meal, to add up to give you the right Poshan.
