When you no longer have love-handles, but arm-rests.

When you have to bend over backwards to get off the couch.

When you have to turn sideways to get through the bathroom door. *all of these apply to me lol*

I actually got found out by my mom...that made for some awkward conversation. When she figured out that I was a gainer that made it even more awkward. She did almost the exact thing that your dad did, suggested mental help. But in the end she seems to have accepted it, and the fact that I haven't gained any large amount of weight since then helps too.

So I guess what I'm saying is just chill for a little while and you father may forget about it as the bigger issues come along.

In all likelyhood you wouldn't gain that much weight a day. When you really overload on calories your body actually throws a lot of them away because it can't process that much. But drinking a bunch of those would definately kickstart your gaining.
