Don't feel bad about not noticing he was fat. It's not easy with birds... for one thing, nobody can tell by just looking and, for another, you need A LOT of experience to be able to tell by just feeling. People say 'feel the keel bone' but birds that have a lot of muscle from flying would feel quite plump on the chest while birds that don't fly can have a keel bone that sticks out and still be overweight!
Now, I don't know if your vet did a bile acids test on him but, if he/she didn't, I STRONGLY suggest you request one because when birds have globs of fat under the skin, they always have fatty nodules in their liver -and that means fatty liver disease (hepatic lipidosis). The thing with the usual avian biochemistry panel is that it doesn't have a single value that is liver specific and, the ones that 'cover' liver as well as other organs only measure liver disease when the liver is beginning to fail so you can have a bird with a liver working only at 25% and still show normal values. The ONLY test that measures liver function is the bile acids one and it's highly recommended it's done on any bird that has been on a bad diet for years because, and these are the great news, the liver is the only organ in the body that actually regenerates so, if you catch it in time, you can not only stop the damage but also reverse part of it. (If he is found to have liver malfunction, I can point you in the right direction for the natural supplements you can use to fix it).
Now, I assume that your vet told you to feed a measured amount of pellets as part of his diet -please correct me if I am wrong because the following is based on this assumption. The problem with feeding pellets to a bird that has an eating disorder (that constant eating and eating is a clear symptom of it -it usually happens to birds that were not weaned the right way) is that you will end up with a very unhappy bird. Pellets are grains that were ground up into a paste, dried and compressed so they not only have a long shelf life. But the 'side effect' is that you end up with a food that occupies a small space (think of dry sawdust versus wet sawdust) and this is the same small space it will occupy in the bird's crop because parrots don't have saliva in their beaks or in their crops (the moisture part comes later in their digestion process and that's also why I think that pellets are not the best dietary option -I can explain this further if you wish, just let me know). Because birds fill 'full' in their crop, feeding them a small amount of pellets would make them feel not sated.
I would recommend you consider gloop as the staple. Gloop is, same as pellets, whole grains but, unlike the ones in pellets, they are not dried and compressed, they are actually made plumper by infusing them with water as you cook them which is ideal for overweight birds (the higher the moisture, the bigger the volume, the smaller amount of carbs you need to ingest in order to feel full). I have taken in several overweight birds as well as ones with liver malfunction (I actually have three of them right now) and all of them have done wonderfully on gloop because it has all the necessary elements: low protein, almost no fat, high fiber, low complex carbs and no simple ones. And it's also a wonderful medium for supplements.
