Please, don't knock it till you try it OR at least do a little bit of research. Soylentarians are bombarded daily by the uninformed opinions of FoodBarbies and the like. At least do some research before you decide to tear down the idea.
I personally dislike official Soylent (own it, tried it, don't like it). With that said, i've been on 70% DIY Soylent for ~9 months now. I couldn't live without the stuff. While i may not like official Soylent, i am ever grateful. It's been a huge boon to my life.
Aside for that, in what way was this a huge boon to your life?
It also is worth noting that i meant meals, not calories specifically. When i eat "normal" food, i eat for taste - because DIY does get boring. So, it can range quite heavily in what i eat - but i generally don't hold back. I'm a thinner guy anyway, so i don't worry about calorie intake. I drink/eat soylent for the ease of use, stability in meal consumption (i used to skip a lot of meals), and a nice feeling bloodsugar level (i have not tested my bloodsugar, strictly speaking about how i feel).
edit: Oh, and the boon, as i mentioned before is.. well, all the benefits i listed above. Specifically stability in eating. I don't skip meals anymore - which is a big win for how i feel. Moreover, a good chunk of the meals i didn't skip in the past, were filled with horrible "just make hunger go away" type meals. I don't eat fast food, so it was usually just random junk in the house. Lots of cheese, usually hah.
But the plusses for Soylent are more time, more money, less hassle and more consistent nutrition.
Furthermore, this mix really leaves my bloodsugar level feeling amazing. I really have to eat balanced meals, or i am left feeling woozy/shaky. I am left feeling almost entirely neutral after DIY Soylent (this specific variety of course).
If anything, the only downside of it for me is the neutralness. Sometimes i am left a bit bored. Quite funny considering i started doing this because i had terrible eating habits due to time restrictions, and now i complain about having to fill time that would otherwise be left with food preparation and consumption hah.
As a sidenote and unforeseen benefit of both DIY and Soylent - they make amazing road foods. When i am driving somewhere far away, i always mix up a bottle of my DIY. And i always bring a pouch of Official with me, for the way back (and random times when you might be stuck without food). Official Soylent plus a bottle of water and a blender bottle is a pretty nice meal in a pinch. Even if you don't want to eat the stuff regularly, i'd recommend it to anyway for road meals.
I understand proprietary formulas wouldn't be made public, but they start off stating "Due to U.S. food regulations..." What food regulations would prevent ingredients being shared?
the only accurate way to determine your caloric maintenance would be to track your food intake while you remain weight stable, and then substitute that with an isocaloric amount of soylent.
They seem to gloss over this and blanket recommend 2000 cals per day
The FDA guidelines do not recommend any number of calories a day. The % DV is based on the recommended amounts for a 2,000 calorie diet, and there is a standard, required, footnote noting this and that actual DVs vary by calorie needs.
Soylent does not recommend any number of calories a day.
I also think the serving size fits into how I use the product. I usually go a couple days consuming only Soylent, and then have dinner one night and then back to only Soylent for a couple more days, and repeat. But either way, I usually only have a pint for each meal. So even if I have nothing but Soylent one day, I still only use 3/4 of a package. I never was able to drink an entire pouch in a day.
Top ingredients of Soylent:
High Oleic Sunflower Oil, Rice Protein, Oat Flour, Isomaltulose
Top ingredients of ensure:
Water, Corn Maltodextrin, >>>>Sugar<<<<
Have you compared the two nutritionally speaking? If so, what led you to believe they were so similar?
To me the differences are striking - unbelievably so. So much, that you come off as a troll. Please inform me otherwise.
does soylent recommend a blanket amount of product to everyone per day, with no variation in individual metabolism?
or do the have some kind of induction period where they figure out your maintenance caloric intake and then give you enough soylent to satisfy your caloric needs?
edit to add a source (many more are on the forums):
> Then, a bit before midnight, I got a pair of e-mails from two of the folks at Soylent, one from founder Rob Rhinehart and one from customer service vice president Julio Miles. "We encourage Soylent beta testers to decide how much Soylent they require in a day," he said. Rhinehart had a similar message. They both tell me that I don't have to actually eat the entire bag of Soylent.
lentil: 180 g
rice: 180 g
banana: 120 g
olive oil: 20 g
egg: 112 g
milk: 99 g
dry roasted peanuts: 50 g
cost : $1.70
carbs : 200 g
fats : 56 g
protein : 175 g
Those two numbers translate into $50/person/week and $37.5/person/week.
I wanted to try out Soylent for a breakfast replacement, but was also turned off by the price. Edit: Also the delay! Wow, 4-5 months
I should point out, here, that the IOM's recommendation is controversial, and that many would consider 1.64g sodium per day to still be inadequate. (Luckily, getting sodium elsewhere is easy.)
I'm glad Julia Child isn't alive to see this product.
Why not Soylent? Because it will kill you. It's pretty simple, I think. I am a big fan of Michael Pollan, and his main argument is that even nutritionists and doctors, people who dedicate thier lives to studying nutrition, can't answer lots of the more complex questions: "Eat carbs! No, wait, eat protein! No, eat whatever you want, just get enough vitamins! Fast! Eat constantly!" What are the chances that a single non-nutritionist got it right? I think exactly 0, and I'm not willing to prove that theory wrong using my own body.
Edit: ideal situation is where the human body naturally requires only 1-5 meals per week. Then I could easily see myself cooking a few gourmet meals. Alternative: be so filthy rich that you are either less busy or have a chef ready to cook for you any time of day.
One fantastic thing about a versioned product like Soylent is that it actually may make it possible to determine those answers empirically. Given the existence of a simple standardized diet that people are willing to eat exclusively outside of a laboratory setting, you could pay a bunch of volunteers to eat soylent you provide which either has or hasn't been modified to include different amounts of vitamins, different amounts of carbs or whatever.
> I'm not willing to prove that theory wrong using my own body.
Fortunately you can't stop other people from experimenting in just that way. The world is full of people who eat odd restricted diets and live reasonably long, healthy lives. There's no reason to let the best be the enemy of the good. Start with something that's just barely "good enough" and iterate on it until you really have something.
Did you ever explain why Soylent will kill you?
Everything kills you. Oxygen, water, sugar, protein. You have about a billion heartbeats before your heart gets too tired. The goal is to find the right balance of things you eat, do, don't do, etc so that you maximize your useful lifespan. I am sure that Soylent kills you faster than a balanced diet, because (a) it's processed (b) not diverse enough and (c) uses subpar ingredients. It is the whole meal equivalent of hot dogs: techincially has fats, proteins, carbs, micronutrients, but eat enough of them and you will suffer.
Besides, Soylent is not a new idea. Take a look at Ensure shakes. Would you drink those for the rest of your life? If not, then why drink basically the same type of stuff but with a different label? Because a software developer is selling it?
Edit: another idea for a convenient complete meal: McDonalds. Protein (burger), fats (fries), and carbs (soda). Blend it and you have Soylent 2.0.
Completely agree with you about nutrition angle.
On the other hand, when I do manage to make breakfast, I feel like a million bucks!
I like food quite a bit, but i just don't cook often enough or well enough to eat healthy and regularly. So, i found a solution that works really well for me.
Of course, if i had lots of money and a personal cook, i wouldn't drink soylent. I would gladly eat normal food, all the time and on time.
As others in this thread have said - Soylent for breakfast and lunch but real food for dinner sounds pretty good, actually.
I honestly don't understand the appeal of an unproven and difficult to source food product, but I would appreciate hearing your thoughts.
I'd add balanced, certainly more so than fast food and microwave meals.
I bought a month's worth. I only eat it for dinner around 4 - 5 times a week, meaning it will last me 3 months. My time is worth a lot to me, and I would much rather spend the free time I have after work doing things I love to do than things I don't (which include cooking).
I am a bit of a foodie. I love good good, I love going out to dinner, I love trying new restaurants, and I love eating with friends. Soylent does not affect this in any way, because I don't eat out or eat with friends every night of the week.
Side note: People look at the cost of Soylent and don't factor in the cost of the time it takes to gather ingredients and prepare / clean up meals, which is pretty short sighted in my opinion. This cost is not insignificant.
I generally agree, I crave "real" food immensely when I'm eating Soylent a majority of the time, but...
I have pretty severe TMJ and everything I have to chew increases the overall pain that I feel, and it's not temporary pain, it's persistent pain that is actually distracting.
Drinking Soylent helps alleviate this to some degree, to the extent that I'm willing to make a trade off.
I barely managed to swallow the grittiness of the mixture after following their instructions and shaking up my first batch a few months ago. I even put it in my vitamix on high for a while and it still tasted like undisolved powders sitting in the bottom of a jug of water.
I ended up throwing out the remainder of the first mixture, and the rest of my week's supply has been sitting in storage ever since.
Apparently there is a secondary market out there where dissapointed early adopters can sell their soylent to others, which speaks volumes about it's quality/taste/texture... that people who waited over a year for delivery can't even finish the stuff and want to pawn it off to somebody else. 
Why you think Ensure is something you can live off of, is beyond me.
Three servings of 670 vs. four servings of 500-- I don't see exactly what this changes.
Sort of the opposite tactic of most companies who try to squeeze serving sizes to meet certain nutritional milestones despite having no basis in real-life usage of the product. I'm looking at you Pop-Tarts! No body eats one tart at a time.
...But then again, I don't eat an awful lot, and that's why I was originally interested in the "revised serving size"-- I'm wondering what other Soylent drinkers do if their caloric input is usually (far) less than 2000 cal/day.
And dip it in milk or chocolate syrup.
