I want to become a gainer in the next month and gain about 10-12 lbs as an experiment. But I have doubts about all this. If I will have desire to be thin again? Feedee's lifestyle is very addictive, isn't it?
There was an earlier thread here that was titled something like "warning fat may be permanent."
If you were once super skinny, I don't think that will ever happen again. I looked at your profile and you listed your weight as 171. If you try to gain 10-15 lbs, I doubt you'd look that different and it might be a good amount to try.
After a certain point, it would likely be hard to keep the weight off without a dedicated effort as well as eating much less.
Even individuals featured on "My 600 lb Life" (who often have serious problems and aren't happy with the situation) who get the surgery, are typically still overweight/technically obese even afterward, but are never skinny again. All of them still end up being at least 200-250ish lbs. But it's usually a significant improvement in their lives so they are typically satisfied with the results.
I suspect that once you get over 200, it may be hard to get below that again. The lower the weight, the harder it is to lose. But if you get to that point, I suspect you have to at least like it somewhat.
As others have said in replies, others have succeeded in losing 50+ lbs, and it might be possible, but it's not clear where they started from and where they ended up. 350 -> 300, or even 450 -> 300 is going to be much easier than 250 -> 200, which would be easier than 200 -> 150.
I obviously don't recommend the last one (200 -> 150) and not just because I'm an FA.
