What I've noticed is that people who stuff themselves to the point that they can't take a deep breath once a week or more usually can't stop gaining. I'm not saying that's the only "beyond return' point, but it's certainly one of them.

The numbers look right, but these formulas are pretty unreliable. People gain at different rates based on metabolism, digestive capacity, time of the month (from women anyway), activity levels. Calorie count is only part of the story.

Have you read "Deciding to Get Fat" on my site?

I actually wrote that! Thanks for the link.

I think those who are into the erotic aspect of gaining definitely have phases of being more into it or less into it.

Those who are more into gaining because it gives them a license to overeat are probably more consistent.

Well if you eat lots of fattening goodies and you date someone who doesn't usually eat like that, just being around all that food could easily cause them to gain.

I did help one woman with this issue: askdrfeeder.dyndns.org/letters.html#Amanda

As you point out, one can have mobility problems at any weight, but the risks increase as you get bigger.

Personally I wouldn't want anyone I cared about to get too big to get around easily. It's easy to cross the line, become immobile and not be able to lose the weight. Your bf's ex is not the only one this has happened to.

Say you're a feedee and your feeder is bringing over some snacks. Should he/she bring:

a. A quantity you can easily finish.

b. A quantity you can barely finish.

c. An amount you MIGHT be able to finish if you really push yourself.

d. More than you can finish.

I always wonder if some of the gaining web models are doing this irl. I mean, they're definitely getting paid to gain, but I wonder if some of them would rather not but need the money.
