Gaining

I would Love Your expert opinion on a theory of mine fatapple
Let's say we have two identical twin women with hourglass shapes. They are both instructed to gain 50 lbs starting at 5'3" and 120. One of them has to gain the weight as quickly as possible with regular stuffings and daily calorie intakes of at least 6000 calories minimum. She is trying to gain the weight in under four months.
The other has to go much more slowly. At the rate of a non -intentional gainer. She is to attempt to gain the weight in 18 months and her shortest allowable time is one year.
I feel that the slow gainer would tend to get a very even distribution of weight. Buttocks. Thighs. Breasts. Belly arms.
And I think that the faster the quick gainer accomplishes the task the more weight would be concentrated in the Belly and Love handles while certainly growing some in the other areas as well.
Am I completely wrong about this?

Rate can have an effect on distribution. But that's usually more of a case of visceral vs. subcutaneous.

Some foods are associated with certain areas of the body. But I don't really believe that makes much of a difference.

No. It's purely a Theory.I just think that a very fast gain tends to go more to the belly because I think bellies take on fat quicker than other body parts.And since so few people gain intentionally.And even many intentional gainers aren't that proficient at high speed gaining.I might Never be able to prove it .

And if I had the resources I would love to test out my Twins theory.
