Yoda used to do that, years and years ago. I switched him to strictly canned
food, and he never throws up anymore. Unless he gets into Bootsie's food, who
eats Proplan Salmon & Rice in addition to canned. He throws it up every time.
It always comes back up as undigested kibble. I don't think wolfing it down, or
the amount he consumes,  has anything to do with it. I think, for some reason,
dry food just doesn't agree with him.

I'm left with the impression that the food he is being fed doesn't agree
with him, so he is avoiding it until he is starving.

Have you thought about adjusting his diet? Perhaps introduce him to tinned
food?

Perhaps leave some amount of kibble out for inbetween meal snacks, but feed
tinned the majority of the time?

This is how I feed and over the 3 years my cat has been with me, she has
only barfed twice - nothing to do with the food.

I would put the cat on a canned diet, preferably a high quality food like
Wellness or Felidae.  Dry food really isn't appropriate for a carnivore anyway.
It's actually healthier for your cat to be fed a mostly wet food diet.

When I have problems with cats, I try to view it as what I would do if
I had a little human.

With humans and food allergies, you limit the food to something fresh.
For example, only rice and lamb and then add 1 food per day.

With a cat, I often might make some fresh chicken, chicken that is
antibiotic free and free-ranged chicken, old-fashion chicken, unlike
that horrible penned up chickens. At least these chickens had a chance
to stretch before slaughter.

Now fresh chicken is not sufficient. So be careful, don't do this as a
long range thing unless you can supplement with vitamins and the right
minerals. But for a few days, you can see if pure, cooked chicken is
good. I just put it in a microwave with some water, so the chicken
becomes cooked and a wee bit stewed. Takes only a few minutes, and
it's quite tasty actually. I tend to steal it back from the cat so I
have to control myself.

I cook the chicken to make sure it's germ free. I know the cats can
eat germs but who knows after being indoors mostly. I use only meat
part, no bones. Not cooked bones ever, dangerous since they splinter
unlike raw bones probably.

It's also possible that your cat might have a tummy problem. Don't
know. A large number of humans, for example, have H. pylori which
mimics ulcers and can cause ulcers and cancer, but never get it
diagnosed or treated, except using stomach antiacids which just masks
the problem.

You might have to review this with your vet.

When I took care of a sick cat, I made for her some chicken livers for
high energy food that she loved. For short time, it's fine. Certainly
safer than cow livers which you find in most tinned foods. I figure
chicken livers are smaller so less polluted, but who knows.

I am not familiar with the hypoallergenic food you mentioned but
hopefully it is truly hypoallergenic. If not, you can try my method.
The only drawback is that it is labor intensive and probably far more
expensive.

Why? If I can't buy good quality chicken cheap enough to compete with
the tinned food, makes you wonder what crap they put in the best of
tinned or canned food?

One of my cats was adopted as a starving kitten, and apparently
has anxiety about an empty dish.  If I let the dish get empty,
he will gorge until he throws up.  He's 12 now, and I usually
make sure there is at least a little food in the dish, but if
it does get empty, he'll binge.

What's worked for me is to try to distract him while he's binging,
by talking to him and petting him.  That way he slows down some and
sometimes realizes he's had enough, before he eats so much that he
throws it up.

I can't imagine why your cat leaves the food all day and then binges,
though.  Does he do this with different foods, or just one you've been
using?
