Everyone is different so that is a hard question to answer.

I found I could feel new fat in my underarms and inner thighs first.

I am so happy for you.
Encouraging is a good thing when done with love.

I tried the feeder angle and really wasn't into having someone force me to eat.
So basically was never into the feederism thing but do support those that wish to indulge in it.

I hope all goes well with this endeavor.

I was an active gainer for years and stayed around 325lbs for a few years then my long term BF moved out west.
I was bummed to say the least and that is probably when the eating disorders began.
At least thats what my Dr thinks.
Life is good so I don't let it bother me these days

Oh not to worry.
I'm a big eater anyway and don't care if I gain when a binging spell hits.
I enjoy being fat and made the choice to be this way years ago.

I deal with compulsive over eating disorder and I have spells where I eat constantly/ binge eat.
Weight gain always happens a month later of course.
I had a binge eating spell early this year but haven't had one lately.
My weight fluctuates all the time.

No reason not to at least try to stay flexible and be fat at the same time.

Exercise and stretch/ stay active.
You can gain weight and not be sedentary.
I walk each evening or walk horses for about 30 mins.
I'm fat and flabby so deff not toned LOL
