Transcript for Smartphone Users 'Instagramming' the Weight Off
I think I used it all up. Next up on the "gma heat inde index", can using instagram change the way you eat? According to a new study, looking at all those photos of food may actually, wait for it, make you less hungry. That's the word on the street. Abc's linsey davis has more on the so-called instagram diet. Reporter: Social media is changing the way we eat. I want to know what's the most likes? What will get me the most likes on instagram. Reporter: People are ordering based on the best say cheese moment. What they think will make for the best photo op. You heard that a picture is worth 1,000 words. Now, some say, it could just save you 1,000 calories. That's because according to a study of salty and alternatively sweet foods by brigham young university, it's possible that looking at too many snaps of food on instagram or pinterest can actually curb your appetite for those types of food. It is absolutely possible that looking at too much or a lot of a specific type of food could decrease your desire for that food. Reporter: But not everyone agrees. 30-year-old natasia johnson has more than 4,000 followers on her instagram page that she devotes to her love of sweets. It doesn't change my appetite. It probably makes me hungrier for food. Reporter: For johnson and many like her, posting pictures of food has become a bit of an obsession. I'm a little obsessed with instagram. I follow about 400 people. And it seems to not be enough. Every time my hand gets near the phone, instagram's the first thing I open. Reporter: But picture this. According to the study, you can't count on one or two pictures of chocolate cake to make the real cake in front of you seem any less palletible. But after seeing 60 pictures of sweet foods, you might be less likely to enjoy the real-life cake and possibly eat less of it. For "good morning america," linsey davis, abc news, new york. For more on what some are saying, the surprising new study, we turn to nutrition and wellness editor, dave zinczenko. You didn't bring any food. We're disapointed. That's right. The study says it doesn't make you hungry. We've been watching this piece for the last minute. And we're -- salivating. It's a little of a tough one to swallow because if you realize you have to, like, see 60 photos to hit sensory boredom. That's an overstimulation of your senses that lead you to not want to eat it anymore. And it has to be the food you're trying to avoid. So, that's -- brownies are not for me. This is becoming popular, posting food online. Everybody has to eat. Everybody loves food. And so, it's the one conversation piece that anybody can have. So, whether it's -- you're just talking about food, pure love of food or your interest in weight loss or you're trying to stay on top of the merging nutrition and wellness trend, it's easy to get into food. But it's not, again, as simple as you see a picture of an ice cream sandwich. So, you won't want an ice cream sandwich. You have to saturate, go beyond that point. The good news is that people want to take sexy shots of food. That means colorful foods. Nectarines, and lima beans and kale seems exotic. It tends to be healthier food. Looking at the pictures, you'reight. It's beautiful. I still want to eat that brownie. In many cases you're talking about gorgeous food shots. Professional stylists and photographers. So, it's easy to make it seem appetizing. When we try to make it at home, not so much. Thanks very much. Thank you. We have been blown away this
