if men had ever been suspicious of all this vanity sizing. >> you know, it makes you think like you've worked so hard to lose weight and to be fit and they're telling you the wrong size. >> i'm hurt. i'm hurt. i mean, i honestly don't know. i think i would just try it on. >> well, i noticed that from one brand to another it's different. from one store to another it's different. >> they tell me i'm 31, it fits and it works, i'm 31. they tell me 32 and it fits and it works i'm fine with that too. >> reporter: these waist size white lies are no laughing matter. a report recently published in "the archives of internal medicine" show men with waist sizes of 47 inches or bigger have a greater risk of dying from a health-related issue. if you think your pants measure 42 to 47 inches you might want to take a tape measure with you the next time you go shopping.
