500g low-fat yogurt with a scoop of muesli.

Yogurt is dairy and since most cows now are the bastardized ones that only produce omega 6 and aren't even grass fed, you are eating a less healthy food. Muesli is grains mixed often with brown sugar, dried fruits, all of which are not really that healthy. Plain rolled oats are one of the healthiest grains, but all grains are basically not good or should only be consumed in moderation. Fruit should be consumed fresh. Sugar should never be eaten.
