"A recent study has shown the no. 1 fear for women dating online is that they're going to meet a serial killer. The no. 1 fear for men - that the woman they meet is going to be fat," the video's creators said.
And for the most part, it looks as if their experiment confirms that study.
As one date's agitation radiated, Sara couldn't help but ask him what was wrong.
"I'm sorry, you just seem really uncomfortable. Are you OK?" she asked.
"Yeah, no, I'm just a little agitated, when you expect something to be one way and then it's not," he replied heatedly.
As one man stood up, he said, "You look more ... voluptuous," and then asked, "Are you pregnant?"
Taken aback by some of these responses, Sara replied, "This is me. It's all about what's inside, I think," to which her date replied, "Some people see it that way. Some people don't."
Eventually, one by one, the men stood up and walked out on her. One man made the excuse that he had decided online dating isn't for him. Others were more blunt - one man left saying, "I really don't appreciate people lying to me."
Another got angry, saying, "It's very upsetting. I'm a little upset. I wasted gas and my time to come over here, and I can't do this," and then stormed off.
Other men lied to get out of the date, saying they're married or claiming they're going to the restroom and then not coming back.
Sara just smiled disbelievingly into the camera as each one walked out on her.
"You're the only one who stuck around"
There was only one man who stayed - he didn't radiate anger or discomfort during the date, but instead showed kindness. He was the only one who got to find out he was part of a social experiment and that his date was actually wearing makeup and a body suit.
"I have to tell you, you're the only one who stuck around, and was like, really sweet and really nice," Sara told her date.
We'd all like to think that the men we know and love would treat the women they meet with decency no matter what they look like. We hope the men in our lives have the kindness of the one date in this social experiment who stayed.
But in reality, many people experience fat-shaming every day.
Other than the obvious effects of fat-shaming - saddened and hurt feelings of those on the receiving end - scientific studies have proven serious health effects are involved as well.
One study shows that mental health issues are more common for those who have experienced weight discrimination; the risk of becoming depressed is nearly three times as high.
In addition to mental health, a new study found that women who experience fat-shaming are also at risk for physical health problems. The study concludes that overweight women who hear and believe negative messages about their bodies are at a greater risk for heart disease and diabetes than those who maintain a more positive body image.
"There is a misconception that sometimes a little bit of stigma is necessary to motivate people to lose weight," said lead author Rebecca Pearl, PhD, assistant professor of psychology in psychiatry at the University of Pennsylvania's Perelman School of Medicine. "But time and time again, research shows that this is just not the case."
The cliché that Sara quotes during the experiment, "It's what's on the inside that counts," has more truth and relevance than we sometimes realize. Hopefully social experiments and scientific studies like these help us realize the ugliness of fat-shaming and judging people because of their weight.
We can all learn a lesson from the one sweet date who not only didn't walk out on Sara, but showed her kindness and respect.
