I want to use olive oil, to be on the healthy side, but I don't know what to mix with the olive oil to create an easily drinkable weight gain shake. I want to mask the taste of heavy fat, when the gain shake reaches around 50% fat content.
I also want to avoid lecithin, as there are some studies that indicated that lecithin is really bad and causes heart disease.

What have your experiences been? I would think that the same probably also applies to other vegetable oils.

I think this is very common. I used to be a feeder only, was afraid to gain, because I thought that no women were into this. Then I met a lot of them and I could tell they were real, many of them very attractive and then I started gaining and being also a feedee. I think everybody is a feedee and feeder at the same time, but might only act out one or the other. I know that when I'm a feedee, I have a part of me that is feeder that wants me to gain and balloon up, when I feed myself and make myself gain. I love to be in the position to give and receive at the same time, to be a feeder and feedee, so basically a mutual gainer. Unfortunately, these are really rare I found.

What a wonderful idea and dream, I have it also again and again. And it is hot that people are getting fatter and with that, appreciation might also change and fat hate and fat phobia might finally stop.
For me it has been very interesting, as I used to be thin and for years now have purposefully been fattened up and grown larger and large and am entering the realm of obesity, which feels so magical.

This world by the way, where everybody is fat and happy with it does exist:
Go to the BBW Bashes, preferably the large ones, I would recommend the one in Vegas, it is a whole week of living in a world where everybody is fat and loves it and dresses to please, to show off their curves. And for me it is like being around super models, it is so wonderful and inspiring to see so many incredibly fat men and women and that even at the pool side, see women that are 500 pounds, yet wear a bikini and know that they are sexy and beautiful. A total dream!

It is not really that easy, but a big mix of all kinds of foods will help and overeating of course, stretching the stomach to hold more, more calories to digest and fatten you up.
I have made great experiences with taking a small glass of olive oli every 8 h or so, not too much, around 25 ml to 50 ml, because the body cannot digest that much fat at once, but the little portions again and again has fattened me up.
I take the olive oil in the mouth really quick and then quickly flush it down with orange juice or something, so that the tongue cannot taste the pure fat, which normally is not pleasant.
You can also take cream, that is not pure fat, but tastes better. But there might be some health implications about the bad kind of animal fats that olive oil does not have.

I always write stories while I masturbate, I have written a huge number of very long feeding stories thanks to that and I noticed that with people reading them, the sexual energy comes out again and this is very exciting for both me and the readers, since I know that it does that.
I love to turn people on with it. Due to masturbating and being very horny during it, my stories are very sexual and I don't beat around the bush about what I write.

In them, and some seem to become more and more real, I fantasize about women gaining and fattening, but also me gaining and expanding. And the realism is that I'm currently gaining and that it feels wonderful to hold that fat belly and see how it is growing and expanding.

Oh wow, that sounds so sexy, getting huge heavy jiggly breasts with water balloons, simulating when your breasts get this large due to fattening, how hot is that? I love it!

I think that a lot of women do gain, but are terrified of the baby gain and want to lose it as fast as possible afterwards, due to societal pressure and the perception that getting fatter after a baby is not attractive.
I think the contrary is true: Gaining a little or a lot due to a baby and then keeping the weight, settling into the new role is very sexy and natural. Fat for me often stands for sex and sex leads to pregnancy and pregnancy is life, so fat is life, it is a life insurance for the bad times. It made a mother and her baby survive really bad times. This is from a long time ago, but we are still wired that way. Some of us can feel this and feel how sexy and attractive fat is and that is for both partners, because of course the same applied to the guy.

That would be very useful and others have implemented this already. Feabie has it. It is very relevant, especially since real life meetings, and the likelyhood of them happening is directly proportional to the distance. Now I know this is not so easy to retrofit on the existing website, but it would be really worth it.

That's a really great idea, I would love to buy one of these calendars. Would also promote the site.
Could of course be done in such a way that only people that want to participate and give pics for it.

Fat definitely creates fat. I have noticed that I got more interested and excited to put on more weight since I have gotten a little fat belly. And I know that it will speed up still, right now I'm just being fattened by my feeder these days and it feels so wonderful carrying a lot of fat in my gut and waiting for it to start making me balloon up with more fat.
For me it is like being seduced by the fat.
