Bulking = Permanent new fat cells?

[James432213]

I read that when you gain new weight you permanently gain new fat cells because your fat cells at that time have filled up and new ones need to be made. When you lose the weight the new fat cells you gained remain and can never be lost.

True!?

 

I did an unncessary  insane bulk last year probaly to like 20-25% bf, am I forever stuffed now?

Most importantly is there an visual appearance difference between some one lean at 10% bf  with a lot of fat cells and some one lean at 10% bf with little amount of fat cells?

 

I noticed when I cut my dimples on my face did not go away were they previously were absent at the same 'cutted' bf %....

No no no.

 

The number of fat cells in your body remains fairly constant throughout your whole life, regardless of your bodyfat percentage. New cells are created at a constant rate to replace the cells that die. The only difference is the size of each individual fat cell, which increases/decreases as you bulk/diet.

 

The same thing applies for muscle cells, which is why HGH can increase the maximum size limit as it promotes hyperplasmia, the creation of new muscle cells.

 

So no, you can't use the excuse that you bulked too hard and created too many fat cells for the reason that you can't resist eating ice cream at night when everyone else is asleep.

A fair amount of recent research suggests that rapid or extreme fat gain as an adult will increase your number of fat cells. I dont think it's an accepted fact yet though as some research may be conflicting. 

 

I did a quick squiz and there are a couple from 2010 or later. 

This is humans:

Not sure what else is out there.

One other school of thought that's worth mentioning...

Whether or not you create new fat cells, your body does seem to establish a "set point". So if you've been fat for a while, your body considers this normal, and for a while after you cut, it's keen to restore "normality". Conversely, if you're lean enough for long enough, it gets easier to keep yourself there.

At least, that's the theory.
