Irony Open Response for Junk Food Heaven

The irony shown by Bryson is that he thinks he wants to eat and live junk food but when he finally gets it, he regrets buying all of it. He was convincing his wife to buy junk food because he is living in America and he wants to try all the junk food while she was buying only healthy food. He was too excited when he saw all the junk food in the store and all he thought about was junk food. He got so much of it and his wife insisted that he could only buy it if he ate every last bit of it. He wanted all the junk food and when he got it, he realized that he didn't want it anymore.
