In general, there is nothing specifically wrong with quick oats as part of a
balanced diet. However, as I said in my reply, mofoe's diet is anything but balanced: it consists primarily of processed carbs. In large quantities, these may screw up hunger levels, energy levels and the fat storage processes of the body. Of course, of the carbs he eats, the oats are probably the most healthy because of the whole grains, fiber, vitamins, etc. Still, depending on the brand, there may be lots of added sugar or various artificial ingredients.
If you like oats, by all means keep eating them, but just check the label and try to find a brand that uses as few ingredients (especially artificial ones) as possible. Alternatives for oats depend entirely on taste, but some typical choices include eggs, cottage cheese, yogurt, bacon, nuts, nut butters, and fruit.
Every time I go back to look at this, I seem to find a different answer.
This article and
this article present a lot of the conflicting findings. In the end, I think it is far more important to ensure that your overall diet is solid through out the day then stress about the exact contents of your post workout meal. And if in doubt, just drink milk in large quantities and you'll be fine.
