Elliot says, "You're fat" when weighing his alien friend in E.T., the Extra-Terrestrial. How much does E.T. weigh?

In E.T., the Extra -Terrestrial (1982), the weigh for E.T is shown to be 35 pounds. There is a specific scene where the following happens:

E.T.: [steps on a bathroom scale, it reads 35 pounds]

Elliott: 35 pounds? You're fat!

E.T. is a scientist. He’s physically weaker and smaller than a human, but has superior mental faculties. He’s also able to move objects with his mind alone.

Empathy allows E.T. to feel the emotions of others in his group while Broadcast Empath lets his group know his feelings. At one point, E.T. watched a scene from the Quiet Man and Elliot re-enacted in real-life what was seen on-screen.

When E.T. drank beer at home, Elliot burped at school and showed signs of being drunk. Another time Elliot screams for no apparent reason and when asked what was wrong he said, “I don’t know…something scary”.

Also, when E.T. gets captured by heroic government forces, it looks like he tries to kill Elliott through their symbiotic link purely out of spite. E.T. history at being a good friend on the surface is not too great. So he is accordingly getting fat.
