For many Americans, money is not a topic that's openly talked about. Some are so willing to avoid the uncomfortable discussion that they'd prefer another much-maligned subject: Their weight.

In its 2017 Money Matters report, investing app Acorns surveyed more than 3,000 Americans between the ages of 18 and 44. When asked, "Would you rather talk about how much you weigh or how much you have in savings?" 68 percent chose their weight.
