Soylent and VERY high cholesterol?


I have familial hyperlipidemia, which has resulted in my having insanely high cholesterol (currently 388, and I am a 28 year old woman). I’ve been using Soylent for one meal per day for six months. I am getting to a point where I am desperate to lower my cholesterol as much as I possibly can without medication, and one of the ideas that’s crossed my mind is to try going 90-100% Soylent. Has anyone with stupidly high cholesterol like mine tried this? Or is anyone knowledgable on the topic and could speak to whether this would most likely help or hurt? Thank you! :smile:


Soylent is extremely low in cholesterol, so it should help more than any other diet possibly could. I don’t really know anything about hyperlipidemia though, so I could easily be missing something obvious. Needless to say, your doctor would know best.

EDIT: Yup, I was missing lots of stuff :expressionless:


Dietary cholesterol has little to no impact on blood cholesterol.

With that said Soylent is high in monounsaturated fat which studies show improve good cholesterol. The American Heart Association (AHA) recommends anyone looking to lower their bad cholesterol should keep their saturated fat to less than 5-6% of calories which Soylent is doing.

Of course there is the usual exercise, lose weight, moderate drinking.


Thanks. Yes, I’m aware that dietary cholesterol has low impact on blood cholesterol… that’s not quite what I was asking. There are other dietary changes a person can make that have been shown to help lower blood cholesterol (such as a low GI diet, for one example) so I was wondering whether, in general, anyone had thoughts on whether the makeup of Soylent would likely cause higher or lower blood cholesterol. Not all kinds of diets are created equal in this regard, even if calorically their contents are the same and alcohol is not involved.

So - your thought is that Soylent would lower it because of the monounsaturated fat? My “good cholesterol” by itself is within normal range, it’s my “bad” which is a nightmare.


The best way to lower cholesterol by a long stretch is exercise. If you do not feel you have the energy for it, Soylent may be the answer :smile: Better food leads to more energy which leads to exercise which leads to lower cholesterol.

I think the effects of Soylent alone on cholesterol depends alot on your previous diet. If you eat lots of sugar and trans fats, then yes - Soylent will be drastically better.


Well, I do exercise regularly, though it would be possible for me to do more. But you make a good point about the previous diet thing - I don’t eat a lot of trans fats, but I do think if I were eating less “regular food” (including desserts) I’d be cutting down on sugar. I do add some protein powder to my Soylent though, and that adds some sugar content too (I’ve tried quite a few other kinds with less sugar, and they all make for disgusting combinations!). I find that when I am not exercising regularly, Soylent is enough, but as long as I am, Soylent alone can’t keep me full, even if I’m having the same number of calories (i.e. more Soylent and no protein powder vs less Soylent and protein powder).


Being your hyperlipidemia is genetic in nature Soylent alone may not be the answer. A combination of approaches including medication, exercise and diet ( including Soylent) is the best approach.
My personal experience has been lowering of both my total cholesterol and LDL (bad) cholesterol while maintaining my HDL (good) cholesterol over the 2 years I’ve been drinking Soylent (I was part of beta phase so yes 2 years).
Given the risk of hyperlipidemia be sure to discuss with your healthcare provider. You should take a copy of the nutrition facts with you.


Well, I do recall a few people saying their cholesterol dropped quite a bit over some months while on 75-95% Soylent. There were before and after blood tests… somewhere on discourse.
To my memory, these people had drops in both bad and good choleterol… which was basically a bad thing, because their good cholesterol went below the recommened amount.


A couple:

Probably more around as well.


Please be careful writings this, horsfield. I know it’s the en vogue dietary advice, along with fat consumption not mattering. And from your writings I do know you’re quite well informed on science, diet, etc. But on this one area there is a lot of misunderstanding, even from many non-specialist doctors.

(I’m not a doctor disclaimer: I’m not a doctor. I do have a non-majority genetic variant that has caused me to look into some specific cholesterol research findings.)

The best, most concise explanation I can gather is that dietary cholesterol doesn’t matter… except when it does; like with carriers of one or 2 alleles of the ApoE4 gene (me). In this case, with perhaps 20% of the American population–it can vary widely within in various ethnicities and nationalities–the best dietary results seem to come from very low dietary cholesterol, saturated fat, and total fat, in that order of significance. Basically a vegan diet. I don’t follow that diet, but it’s becoming more and more convincing that’s what I should be doing to reduce my higher heart and Alzheimer’s disease risks. (I’m certainly open to discussing findings contrary to those; it’s a very confusing and under explored area.)

@kmbirkel’s cholesterol issues could be related to something like ApoE or a number of other things I know little about. So, I’m just saying a little caution is warranted in cases like this where some non-typical things might be foinf on. And @kmbirkel I’d urge you to consider seeing a cardiologist if you don’t feel your primary care physician is looking in depth to this issue. You’re young, but now’s the time to find out what’s going on so you have the best chance of lowering risks.


I’ve heard high doses of niacin can lower cholesterol.


This is a three-year old thread. My cholesterol levels are low, and I’ve been consuming a lot of Soylent for four years.
