Japan is known for the longevity of its citizens, but recently there’s been a growing trend of obesity in the Land of the Rising Sun.

Thankfully, there’s a solution!

Enter the MXP Calorie Shaper Pants.

For a whopping $32, these shiny boxer briefs purport to aid in the burning of additional calories.

The secret (apparently) lies in their resin coating, which makes them stiff. This added stiffness provides resistance, leading to an increased number of calories burned.

For example, a 140-pound man walking 90 minutes per day can burn upwards of the equivalent of a half liter of beer a week.

Maybe they should bring the underwear stateside, given how utterly obese our country is. Recent statistics show that 35% of America is obese, while only 5% of Japan is.
