Gaining

This really is just about motivation (as someone stated before in a comment).

You are able to lose the weight. Even if you get really fat. It just takes a lot of work and effort, you need to take up new healthy habits and exercise (depending on how much you wanna lose and in how much time, this can vary). But yes, it is possible.

I would like to add also , the older you get the harder it is to lose (metabolism) Even if you were motivated to lose the weight, you would still be flabby from the stretched loose skin.

I'll echo what others said. It gets harder as you gain more. I think thats partly because of how your lifestyle changes.
You get used to eating and laying around.
It takes a lot of effort to change that around.

I would be concerned about all the extra skin flopping around if weight loss was extreme.

Remember, that your weight is different from your fat. When you gain, once you gain a certain amount, your fat cells get "full" and your body makes more fat cells.

When you lose, the fat cells get smaller, but you do not lose any of them. In a sense you remain "fatter" even as you lose weight. You will always have to limit calories and/or burn extra calories in some combination to avoid gaining the weight back because your body wants to restore all those shrunken fat cells to normal size.

So in a certain sense, getting fatter is a one way street and your body considers any lose of weight starvation because those fat cells are shrunken.

The exception is within the "normal size" range of the fat cells. Your weight can vary quite a bit, especially if you are fat, maybe +/-10% or something, while keeping your fat cells in the normal range.

But there aren't ways to destroy fat cells? I am sure that such a thing does exist

liposuction and other surgical procedures actually remove fat cells. Other than that, fat cells are forever.

“Fat cells are forever”. That very much appeals to me submissively.

Depending on how far you go tbh. The fatter you get, the more difficult to impossible it becomes.

Other than that its very much hard work.

There is quite a few posts on here so I am not sure if any of this has been mentioned.

1. If you gain enough weight and Fat it will be tougher to lose it.

2. Re gain is very easy and quick once you have gained a certain decent amount of weight.

3. You create a new set point for your weight.
(wouldn't weigh more than 190 Lbs. then it was 210 lbs. then 230 lbs. etc. etc. your body never goes as low and if it does it climbs back up really fast to the new set point)

4. I know someone mentioned you get used to the lifestyle and laziness that comes along with gaining and not denying yourself. You allow yourself more things in excess than you would have done....and it makes you feel relaxed and happy. Also Muscle memory can relate to stomach stretched memory.

5. If you have the desire or kink to gain intentionally in the first place .....you will probably like it and be on the path to increase time and time again even if you lose a little for a bit.
