This is one of my fantasies. I've done some shakes, but just as shakes.

Being fat is something I love. I love being soft and squishy to the point that I get really horny-- so my squish turns me on, and I want more. It's a lovely way to love myself

I actually just have My Fitness Pal. It let's you set a weight goal, a target change per week, calories needed per day, etc. It doesn't check all the feedism boxes, but it's pretty handy.

My partner is about 40 pounds heavier than me, and I think it's so fucking hot. When I told her I like fat people, she decided she didn't need to diet anymore.

Last Podcast on the Left lol

40 flat. I actually got weighed today at the doctor lol

These are great points, especially for people who don't like to focus on numbers. A lot of people (like me) love seeing the numbers go up, but for others it's the growth, adaptations, outgrowing, etc., and the numbers distract from that or make it less enjoyable.

I would also suggest there is an attitude difference between the body types, as well. A BBW/BHM gained weight and doesn't really want to grow any more because of their lifestyle but they still feel sexy and don't really want to increase activity. An SSBBW/SSBHM might be someone who feels much more attractive and happy the larger they get, although they have hard limits they won't exceed. A USSBBW/USSBHM wouldn't be a person who either has a medical condition or is part of the feedism community and has either grown to the point they are significantly limited in daily activities and likely would not be able to change if they wanted to (which they don't).

So yeah, I think mindset matters, too.

I don't know if there's an actual source out there, but I've always heard that BBW is anywhere from 140 to 350, SSBBW is 350 to 600, and USSBBW is 600+. What's now, there's the 400/500/600/700/800/900 clubs, where the person has reached that weight. That one comes from Dimensions magazine back in the stone age, I think. At least, that's always been where I've seen people comfortable taking the title.

Otherwise, it's realistically whatever you decide it means. A person could say that their waist measurement is 68" and they are an SSBBW, and they weigh 300 pounds. That measurement would certainly be in line with other SSBBWs and SSBHMs despite the weight being lower.

So to answer the question... it depends.

Just south of Provo, Utah

I started gaining intentionally when I was 19 and moved into my own place. Went from 200 to 225 in just a few months (working as a pizza guy helped). I got into an abusive marriage and slowly grew to 315, but it started to get really bad and I went down to around 250. A few months after my divorce, I started gaining again and got up to ~350. Since then, my physical activity at work became so intense that I went down to about 270 but I've gotten back a few pounds so far.

I'm currently working on a master's degree and my chosen field would allow me to work either in an office or from home. So intentional gains would be much easier.
