(CNN) -- Midway through Jason Dinant's fitness journey to get six-pack abs by June, the 27-year-old had a breakdown.



Halfway through his fitness goal,  Jason Dinant said he sees a four-pack gradually forming.



After months of eschewing junk food in favor of lean protein -- egg whites, chicken breast and vegetables -- he devoured pie. The slice came from Marie Callender's, drizzled with caramel, loaded with candied apples and layered with cream cheese.



Yes, it was delicious, Dinant said.



Then he got home and had a Tootsie Roll. Then, he ate a Klondike ice cream bar.



The breakdown came late February after months of following a lean diet. It also came with consequences.



"When I woke up the next day, I had a horrible stomach  ache," Dinant said. "My trainer said once you're on the diet, you can try to go back and have a day where you binge on bad food and it's going to give you a stomach ache."



Since January, CNNhealth has been following the progress of three iReport contributors as they strive to meet their New Year's diet and fitness goals.



One of them is Dinant, a Las Vegas, Nevada resident, who wanted to get a six-pack by summer in time for his 10-year high school reunion.  He also wants to show off a chiseled stomach on his blog called "Naked Boy News," where he stands shirtless to give "the naked truth about today's news."



The junk food breakdown came after almost two months of staying on a lean diet.  The self-described "candyaholic" often craved his favorite treats like York Peppermint patties, macaroons, Mounds bars and Coca Cola.



"The key to falling off the wagon is not to stay off the wagon," said Gregg Avedon, a certified fitness trainer and model whose chiseled six-pack has appeared on the cover of Men's Health magazine 18 times. "If you fall off the wagon for one day, the problem is it could lead to two days, three days, a week, then you fall off completely. Next thing you know, it leads to two weeks of binge eating."



Dinant has maintained his diet of 16 egg whites, one and a quarter-pound of meat, four cups of vegetables, potatoes and rice a day. He treats himself to one Tootsie Roll a day, and sometimes indulges in gelato.



Dinant's quest for six-pack abs -- which initially included 500 daily crunches  -- brought attention from his neighbors, an egg company that ships him 15 dozen eggs every two weeks and news media such as USA Today and his hometown newspaper, Las Vegas Review-Journal and blogs.



Some people left words of encouragement for Dinant's quest for tight abs, but others were less supportive. A picture compared him to a toothpick. Another one showed a kitten shooting a shirtless Dinant.



"A lot of people said, 'You need to put on a shirt,'" he said, so Dinant set up a Web site called putonashirt.com where he compiled the comments.



The hate mail comes "when they see a thin guy trying to be more fit. They're jealous," Dinant said. The negative comments add fuel to his fire.



"I've wanted to do this before and last year, I had the same resolution," Dinant said.  "I did it for two weeks and by January 15, it was time to move on. So I applied for iReport. I wanted people to follow it, so I'm motivated to do it.  So many people are watching, so mentally, I have to do it. I put my mind to it. I have to do it." Watch Dinant's video



Dinant doesn't have a six-pack yet.



"You can see four," he said.  "It's more defined. The middle two are coming in. I need a tan. I'm so white it's
