Does playing video games cause weight gain?

I'm 15 and I started homeschooling, usually I would work on the computer for a few hours but after that I go straight to playing games on my ps3 like minecraft. Do you think that if I keep this up I could gain weight? (Also I have fast metabolism)

It can depending on your lifestyle on the amount of hours played and your diet. If you keep on track of these you should be fine however, do not follow and just game all day this will lead to major weight gain so keep on track you should be fine

Yes, it can. Not necessarily, but possibly.

If you are not getting enough fresh air and exercise and eating a healthy diet then it will cause weight gain

Decreased activity = less calories needed for fat gain
