Does the Camera Really Add Ten Pounds?

Being a crazy Friends series fan(I mean, I know most of us are) When I watched the series for like the nth time, I had this doubt. This scene.

So in this scene, Monica says that the camera adds 10 pounds to the weight. Do they really? 

Well, when I googled the same, I had loads of answers which says that It does. The camera does add pounds(not ten pounds, exactly! ) but it does. 

According to a famous photographer, when he tried taking a picture of a model with different lenses, he had different outputs. The different lenses did add and reduce the weight to the model's face. Here is the GIF added to show how the different lenses gave different output.

It is because of the change in the distance of the object and the camera lens which some call as focal length. 

From the GIF, it is seen that 20mm lens made the face to look thinner while 200mm lens worked exact opposite to 20mm lens and somewhere like around 50mm, is the equal-to-perfect" output. 

The photographer says that it is merely the perception and exposure to exact light and lens will help us to capture a perfect image.

Most of the times, we would have felt that we look thinner in the mirror than in the photograph. It is because our brain recognizes things which we see through two eyes while the camera has one lens to capture the image. This makes the difference. 

This video from the "Scishow" gives a more clear view about the topic.
