I would caution against feeding only pellets for any extended period of time. Pellets are like vitamins in the sense that they have concentrated amounts of all the nutrients that your parrot needs, but whether or not those nutrients are assimilated properly in your birds body is up for debate, not to mention, it would be just plain boring after a while- no different textures, flavours, or colours (unless they're the artificially coloured pellets). Some vitamins are water soluble and some are fat soluble, if you provide a variety of foods that contain both fat and water, the likelihood of proper nutrient assimilation increases. However, if you are concerned with weight and are not wanting to dilute your birds nutrition too much, just use fresh fruits and veggies that have a lower water content. Adding soaked, cooked beans can help add, fat protein and important minerals and vitamins too. I feed my bird meals with at least 15 different foods in them (including pellets) and he loves it! Of course, if your bird is not used to eating this way, it is probably best to ease him on to different foods. A bit of weight loss and/ or gain would be expected if your diet completely changed, But obviously it is best to monitor it more closely during this time. if your bird's weight levels out once he has been converted fully to a different diet, and it weighs slightly less than he did before, this may not necessarily be a bad thing, perhaps he was slightly overweight before?
Oh, to answer your question more directly, and of course this is just my opinion,
I would suggest feeding your bird the same amount of food he was getting before. So if he was being fed a big bowl of seeds, feed the same amount, just replace half of the seeds with a combination of fresh fruits and veggies, beans, grains, and pellets. after a little while start to decrease the amount of seed and then decrease the amount of overall food until you are feeding him just what he needs to eat. But if he is still underweight, don't rush decreasing his food amount too much.
Good luck with your little guy!
