OK just eat what you like don't feel you have to pig out on junk food to get fat.
Pigging out on junk food gave me indigestion something awful and caused me to break out with acne.
There are lots of decisions to make along the way and adjustments to foods that will help you gain weight.
Heavy cream, Ice cream are good choices.

You have to make a commitment to yourself if you really want to get fatter same as you would to work out going to a gym to lose weight.
It takes time and hard work so don't have the idea that gaining weight is easy because it isn't.
As you start eating larger amounts of food or increase caloric intake with less physical activity your metabolism will start to adjust and start storing fat.
Where it goes is up to your body.

Basically its the luck of the draw.
If you gain a lot in the belly over time it will drop due to its weight and gravity then if you gain more you might wind up with a double belly.
I can tell when I gain a bit because my arms start to rub under my arm pits or my thighs rub more on the insides.

This sounds like its going to be a fun thread.
Wish I had a story to share.

Shred you can't predict how and where your gain will be.

Used to go there 15 years ago but not recently.

I would say you are unsure about what you really want.
Confused ? No I think you know what you want but too bound by society to act on it.
Actually gaining weight takes a bunch of effort on your part its not easy at all.
I do wish to welcome you to FF its nice to have you with us.

Everybody is different so no way to say how much weight you will gain or how fast.
Your metabolism makes a huge difference with all of it.

Thanks John.

Doing excessive drinking caused me to suffer from alcoholism eventually.
Add heroin addiction to that it about killed me.
Party but be smart about it is all I can say.
