Burger King has released a limited-time 'Second Generation Baby Body Burger,' a sumo-wrestler-class burger with 5 patties and 8 slices of cheese, totaling 1856kcal, so I tried it.

Burger King's ' Second Generation BABY BODY BURGER, ' a massive burger featuring five beef patties and eight slices of cheddar cheese, debuted on May 1st, 2026, as a limited-time menu item. With a total weight of 661g and a total calorie count of 1856kcal, it's said to be a sumo-wrestler-class burger, so I decided to try it myself to see just how impressive and delicious it really is.

The collaboration with the Japan Sumo Association is back! Introducing the new 'Second Generation Baby Body Burger,' a super-sized cheeseburger that's a 'Yokozuna-class' clash of meat and cheese, featuring five flame-grilled 100% beef patties and eight slices of cheddar cheese!

I brought it home.

This time, I ordered two of the second-generation Baby Body Burgers. I opted for a 'half-cut' version of one of them, where the burger is cut in half. Each second-generation Baby Body Burger comes with an official sticker from the Japan Sumo Association.

This is the second-generation Baby Body Burger. It has a substantial appearance with meat, cheese, and vegetables piled high.

After subtracting the weight of the plate, I weighed the Baby Body Burger and it came in at 663g. This definitely exceeds the advertised weight.

It contains five beef patties, eight slices of cheddar cheese, four slices of bacon, pickles, and onions, and is generously topped with ketchup and mustard.

This is what the cross-section of the half-cut portion looks like. The meat and cheese are piled high.

It was incredibly heavy and so thick that I could barely fit it all in my mouth even with my mouth wide open. Beef and cheese were piled high in every bite. The sauce was a simple ketchup and mustard, allowing me to fully enjoy the flavors of the beef and cheese. The onion and pickles did a great job, providing a refreshing contrast to the meat-heavy burger. It was a fun burger that made me want to devour the meat like I was in a sparring match.

The price for the second-generation Baby Body Burger is 2890 yen (tax included). It will only be available for a limited time from May 1st to May 28th, 2026, so if you're interested, be sure to go and try it soon.
