Welcome to the forum! I am afraid that human food is not really good for parrots, either. Parrots need parrot food and, although seeds and nuts are OK for them, they cannot be free-fed -which is the most common mistake that people make.
I don't concentrate so much on the actual weight and more on the 'physical shape' the bird is in because birds are like people... one can talk about average weight but it really means nothing because muscle weighs more than fat so a bird can be at what is considered a good weight and still be unhealthy. I make sure they get a good fresh food diet, exercise and enrichement (because a bored bird will eat just to pass the time) and all of mine do great.
My 29 year old cockatoo (as well as all my birds) eats gloop and raw produce for breakfast and a measured amount of nuts and some seeds for dinner. He lives cage-free and has plenty of wood, cardboard and knotted rope for him to chew (more this time of the year as the days are getting shorter). He gets a multivitamin/mineral supplement twice a week and liver tonics and cleansers every day mixed in his food and water (and I would strongly suggest you do the same for yours because at his age and with obesity, it's a given he has been eating the wrong diet so it's extremely likely that he has liver malfunction already -did the vet do a bile acids test on him? If not, he should have).
