This method tends to provide the quickest results, but it is not for the faint of heart or for those who have little bird knowledge. Like the name suggests, this process requires that you stop feeding seeds entirely, and replace them with pellets and other foods. It also requires that you monitor your bird very closely to see that he is eating and not losing too much weight.

If you chose this method, you should have a gram scale to measure your bird's weight daily. Because a bird's metabolism is so fast, they lose weight very rapidly when they don't eat. Unlike a human or dog that can go days without sustenance and suffer little more than an aching belly, parrots deteriorate very rapidly without food. While it is true that most birds will let their willpower breakdown before they starve to death, this is not true of all birds (Budgies [common "parakeets"] and cockatiels tend to be among the most stubborn hookbills when it comes to food conversion). For this reason, an owner must closely observe their bird for signs of lethargy, illness and/or weight loss.
If you do not have a gram scale, and are going to try this conversion method, most avian veterinarians have one and will weigh your bird for you at no charge. When you take your parrot it for the physical exam which should precede any major food conversion, your avian vet can tell you how much weight your parrot can lose and still remain safe and healthy. In general, a bird cannot lose more than 10% of its body weight before risking dangerous results.
The Advantages: This method is very fast. For birds that are initially stubborn, but smart enough to not let themselves starve to death, this may yield the best results.
The Problems: There is a very good chance of severe weight loss here. Progress, food intake and weight loss must be carefully monitored. Any complicating factor such as an asymptomatic illness can have disastrous results (so a pre-conversion veterinary checkup is essential).
