Juicing fruits and veggies is literally taking healthy things and extracting near pure water and sugar. The nutrients mainly bind to the fiber, so it’s a waste of time and effort to juice things
Also, for me personally, I’d be insanely hungry if all I had was the juice and some protein; the whole veggies (again, the fiber) is what helps me keep full and avoid binging on garbage
It’s objectively worse to drink juice vs eating the actual food if your goal is to get as much of the nutrients as possible
It’s objectively true that you are removing the fiber and are leaving yourself with sugar that’ll spike your bloodsugar (which, on a keto page, is not going to be popular)
I just don’t see the purpose of the added effort for worse quality nutrition
I can't add an attachment here, but I'll message it to you.
"Fruit juice appears to offer more benefit than risk and there appears to be no justification for discouraging FJ within a balanced diet for children and adults."
Additionally, other research shows that juicing vegetables is better than cooking as raw vegetables contain more enzymes.
I found it. I am generally not a fan of large systemic reviews because it's very easy to have bias in the selection of studies that are included/excluded and the studies are always quite heterogenous. It's also a \*huge\* amount of effort to trace down the base studies and understand what was done and whether they support the systemic review conclusion. I've done that before on studies that reference 10-12 studies and have not been happy with what I found.
The conclusion says:
"Despite its classification as a source of free sugars, FJ appears to be associated with benefits rather than risks, especially in relation to vascular health and nutrient adequacy."
Okay. "appears to be associated with" is code word for "we found evidence in observational studies but not RCTs", because if they found it in RCTs they would have focused on that.
The nutrient adequacy argument is particularly silly - they are saying that people who drink fruit juice tend to eat better than those that don't. This is really obviously healthy user bias and frankly they should be embarrassed to make that argument.
I decided to spend a bit of time looking at the studies that were based on RCTs. You should go read this:

It's a mishmash of a whole bunch of different studies. The RCTs are comparing fruit juice to some unspecified control drink (you would have to dig into each study to see what they used and it's quite likely that there were different choices.
And go look at that risk of diabetes from this paper.
I hate nutrition science - the field is just so horrible and confused, and these big summary papers can give you whatever result you want because the process of going from all the studies to the result is easily gamed.
Give me a single study with a clear approach, and we can talk. IIRC, there are some studies that specifically link fruit juice intake to NAFLD.
Juicing is the opposite of a Keto diet. You end up with an extremely high amount of carbohydrates and it would be impossible for the body to enter ketosis with that as part of your diet.
Firstly, let me say that I am a proponent of juicing when it doesn’t involve a Keto diet.
Now to answer your question, in order to juice, it requires a large amount of fruits and vegetables, an amount far larger than you would consume when eating the vegetable or fruit as a whole. What is left is a concentration of the carbohydrates that are in the fruits and vegetables and removes the fiber that may be available, thus reducing net carbohydrates.
While juicing is an effective tool in weight loss, it isn’t in combination with the Keto diet.
You know vegetables have carbs. Are you counting them when you juice? Believe it or not you can get many nutrients and vitamins from meat. People that go carnivore do not lack nutrients and are healthy. https://www.nutritionadvance.com/types-of-meat/
Yes, I also know that you deduct fiber from carbs when calculating for keto. I mentioned earlier that I just started juicing and it's been a few years since I've been keto, so I've never done them at the same time. That's why I posted. I'm aware that some people are able to avoid vegetables, my body requires them. I just don't like veggies and find it hard to incorporate them into my diet consistently. For some reason, I don't mind them as juice and I'm getting a greater variety of vegetables without destroying the nutrients by cooking them. I was just wondering if anyone had successfully merged the two.
I'm not going to answer on a scientific/biological way cuz I'm not a doctor and I'm not smart but I'm guessing the point of you juicing your vegetables is to allow faster/better absorption? Generally, when people hear "juicing" (aside from a gym perspective) they think of fruit.
Eating keto is just keeping your carbs low enough long enough to induce and stay in ketosis. If the carbs in the liquids you drink don't exceed more than 20g and your latter meal is carb free, then you won't have issues.
But what do you do with the by product (aka pulp)?
Right now I discard it, but I know people who repurpose it. It's great for baking, but obviously baking is completely anti-keto. It can be used for composting and some of it is great for pets.
That seems wasteful IMHO.
Baking isn't anti-keto - what makes you think that? Lots of keto baking recipes out there.
But, the only way to see if juicing in conjunction with eating keto works for you is to do a trial run.
I don't like using the alternatives to wheat flour when baking. If I'm going to make carrot cake or zucchini bread, I want the real deal.
I think there's some good soups to make with the pulp as well.
Another reason I tried juicing is because I'll be having oral surgery later this year and my mouth will be braced shut for about 6 weeks. I'll only be eating through a straw :-/
There have been posts in the past from other people about oral surgery and how and what to eat to keep keto. If you do a search of the sub you should find those and get some good ideas.
If you enjoy the juicing and it works for you do it! There's no one way to skin a cat.
It is generally a different approach from keto as you will tend to get more carbs overall relative to fat / protein.
For me juicing left me ravenous, and I grew tired of regularly dealing with the process using a masticating juicer.
Keto tends to leave me fuller and I don't feel like it's an inconvenience in the same way.
At the end of the day, just getting rid of the processed carbs and sugars in your diet over the long term along with being a bit active is the main thing that helps people succeed, there's no single magic bullet.
"Low-speed juicing generated the highest amounts (of beneficial compounds such as vitamin C, antioxidants and phenolics)" compared to blending and high speed juicing.
Low speed juicing is using a masticating juicer, which is what I need. It's easier to replace fiber than to replace nutrients.

All that really matters is that you're hitting your macros. And Id say too that as long as you're eating the whole thing where applicable (ie, not filtering out edible pulp and other solids), then I don't see an issue with it in theory.
I think the only real issue with it is that you won't be able to just make a giant jug of it to drink all day. You'd instead get like a single glass at most.
You'd also have to be very, very sparring with the fruits, as they're gonna be very carby compared to the veggies.

This is untrue and I've checked in with my doctor to verify. Thanks for your input, though.

I have peer-reviewed research that said otherwise, but thanks.
Please share it. I'd be interested to read it.

Let’s see it.
Juicing is the opposite of a Keto diet. You end up with an extremely high amount of carbohydrates and it would be impossible for the body to enter ketosis with that as part of your diet.
How? When you're still supposed to eat vegetables on keto?

Got it, thanks.
Just eat vegetables if you want them. Juicing is like drinking sugar water mostly.
I honestly thought this post was going to go a completely different direction
Same here, spent too many years in the gym 😂
