“Everything’s definitely a little bit snug,” perennial Nathan’s Famous hot dog eating champ Joey Chestnut summed it up Monday, a day after he shattered his own high mark by wolfing down a record-breaking 76 hot dogs and buns in Coney Island.

Still, Chestnut said, “I feel pretty good,” if not “a little bloated,” as he talked to The Post 24 hours after the live-audience return of the July 4 biggest show in competitive eating after going on a walk and relaxing with his girlfriend.

“Everything’s definitely a little bit snug. I was like, ‘Oh, I really don’t need this belt,” he said with a chuckle as he recalled getting dressed.

Chestnut, a California native who has won 14 Nathan’s hot dog eating competitions, said that he had “crazy dreams,” overnight when asked how he slept with a stomach bursting with beef and buns.

“I had crazy dreams. Like, ‘Inception’-style dreams,” he said, referring to the 2010 Christopher Nolan movie. “I sleep and I roll over and wake up, and I’m thirsty. It’s like I’m in a food coma, like everyone experiences for Thanksgiving, except times 10.”

But he predicted after he’d feel hungry again by Monday evening.

Chestnut said that while he felt “exhausted” after he dominated Sunday’s Nathan’s Hot Dog Eating Contest, and that the feeling a day after hoovering up 26 more dogs than his closest competitor is “not comfortable,” he kept his bowel movements relatively normal by drinking a lot of water and eating a spinach salad — and a yogurt.

“Fiber is really good for me right now,” he said, adding he has no appetite. “It keeps everything moving.”

“It’s a one-way road. All you have to do is keep hydrated, sleep and things are going to work out. Like any recovery period, it’s not comfortable.”

Similar to other competitors, the Major League Eating world No. 1 said he’s primed himself to feel less than 100 percent the day after major contests.

“I expect to be uncomfortable, and then I can accept it,” Chestnut said. “Like a football player, they know the next couple days after a game, they’re going to feel like garbage.

“I go in knowing that the two days after are going to be slow, I’m going to feel gross, I’m not going to have much of an appetite for anything, but I’m going to force myself to eat the greens.”

If he doesn’t eat after gobbling down dozens of dogs, Chestnut said he would experience lethargy and digestive unpleasantness for prolonged periods.

“I’m not a doctor, but I feel like I feel gross for longer,” he said. “It’s almost like I’m trying to keep everything moving, like a cleanse, and have my body get rid of it.

Chestnut, who lives in Indiana, told The Post he tends to digest hot dogs well, unlike sweets he’s speedily wolfed down such as Twinkies and donuts — foods he loves the taste of but his stomach disagrees with.

“There are some other foods that I’m not so lucky with, but hot dogs I have a high tolerance for,” he said. “It accepts them.”

By Wednesday, Chestnut said he’ll “feel pretty close to normal,” noting that he eats healthily and when he’s not training for competitions and takes daily vitamins and other supplements.

“I’ll probably start to get hungry tonight,” the full-time professional eater predicted. “I’ll still feel pretty lethargic and gross.”

He added, “It’s a lot of stuff that goes through my body, so my body is just working really hard to get rid of it.”
