Water vs. plant-based milk in smoothies: pros and cons

8 minute read

Batido con agua vs batido con bebida vegetal: textura y cremosidad

I understand: you're trying to take care of yourself, you buy a good vegan protein... and then the absurd doubt arrives at 7:40 in the morning with the shaker in your hand.
Should I use water? Plant-based milk? Does it matter?
And the typical thing: one day it fits perfectly, the next it's "meh," and you think the problem is the protein. Spoiler alert: often it isn't.

It's about choosing the base like you choose your coffee: some days you want a black coffee, and some days you want a cortado. It's the same with a smoothie.

Quick summary

  • Water : lighter, fewer calories, more "direct". Ideal for when you're in a hurry and after a workout.
  • Plant-based milk : creamier and more filling. Ideal if you want it to resemble a snack.
  • Digestion : If it feels heavy, try changing the base first (before blaming the protein).
  • Oats : the queen of creaminess (watch out for sugars).
  • Soy : usually provides more protein; not everyone tolerates it equally well.
  • Almond : light and smooth (if well formulated).
  • Winning shortcut : half water + half plant-based drink .

What really changes when you choose the base

Flavor: what you notice in the first sip

With water , the flavor is cleaner, more like what it is. That can be great if you don't want a dessert-like smoothie.
With plant-based milk , the flavor is rounded out: it usually seems sweeter and more pleasant, even using the same amount of protein.

Practical example: chocolate with water can be reminiscent of light cocoa; with oats it usually goes towards "chocolate milkshake" (without needing to add anything).

Texture and satiety: why it “feels like food” or not

It's not magic: it's texture.

  • With water , the smoothie is a drink.
  • With plant-based milk , it's approaching snack time.

And here's something important: many people say "protein doesn't satisfy my hunger"... when what's really happening is that they're making it too liquid. Like watery gazpacho: it's not the tomato's fault.

Digestion: When the problem isn't protein

If you sometimes find that your smoothie feels heavy, watch out for this: the base might be the culprit.
There are plant-based drinks with thickeners, with sugars, with mixtures that are great for some people and just okay for others.

If this happens to you, it's normal. It doesn't mean you're "doing something wrong." It's your body saying, "Not this way, not today."

(If you have a digestive condition or a specific medical condition, consult a professional.)

Calories: the detail that sneaks in unintentionally

Water provides virtually no nutritional value. Plant-based drinks, however, can.
Is it bad? No.
But if your idea was "I'll have a light smoothie" and you choose a sugary oat drink, you might have created a snack without realizing it.

The key is not to forbid yourself things: it's to know what you're doing .


Smoothie with water: when is it your best option

Post-workout and busy days

If you've been training and are then going to eat, or if you're short on time, water is the perfect solution:

  • mixes quickly
  • not cloying
  • easy entry

This is truly glorious: realistic health. What you can sustain.

Definition and “light” sensation

If you're in the cutting phase, or simply don't want to add calories with the shake, use water.
And if you're missing the "body" of your drink, try this trick before changing everything: less liquid + more ice . It's a game-changer.

If you find it hard to digest

For sensitive stomachs, starting with water is usually the most neutral option.
Then, if on an empty stomach it feels too "dry", you can go to the middle ground: half water + half soft plant-based drink .


Smoothie with plant-based milk: when is it really worth it?

If you want it to fill you up (without cooking)

There are days when a smoothie is your plan B because you just can't get through the day.
Here, the plant-based drink can turn "I'll have something quick" into "I'll hold out until lunch."

It's not glamour. It's strategy.

For a “well-rounded” flavor with vanilla/chocolate

If you're looking for something that will make you want to repeat the experience (this matters), the plant-based drink is usually better:

  • Vanilla : it's creamier and more "dessert-like"
  • Chocolate : rounder and less "watery"
  • Neutral : it depends; it's the most flexible

If you want to experiment with different flavors without the taste becoming unusual, a vegan protein with clean flavors (vanilla/chocolate/strawberry) gives you some flexibility. At Glorioso, you can find them to suit your needs.

To add energy in volume or long days

If you train hard or are in a bulking phase, a plant-based drink (especially oat or soy) can help you add energy without having to add solid food.

And yes: sometimes the healthiest thing is to eat more , not to cut back.


Which plant-based drink to choose (without falling into the trap of saying "any carton will do")

Oatmeal

  • For whom : anyone who wants creaminess and a "real milkshake".
  • Beware of : sugars and very sweet versions.

It goes especially well with chocolate and vanilla .

Soy

  • For whom : those who want a more "complete" base and have no tolerance problems.
  • Beware of : the taste (some brands taste very different).

It's a good option if you want to add more than just "liquid".

Almond

  • For whom : someone looking for something soft and light.
  • Beware of : “almond” drinks that are really just flavored water.

With vanilla it usually works very well without making the shake too heavy.

Coconut

  • For whom : those who love coconut and want a dessert touch.
  • Beware of : it masks flavors, especially if you use neutral .

Rice and mixes

  • For whom : those who prioritize gentleness and tolerance.
  • Beware : some are less filling.

How to read the label in 10 seconds

Without obsessing over it:

  1. Check if it has added sugar
  2. Check if it has a lot of unusual ingredients (sometimes they're thickeners).
  3. Check if the first ingredient is water (almost always) and what comes next: it gives you clues about whether it will be thick or thin.

Goal-oriented guidance (fast and actionable)

Lose fat / Define

  • Base: water or light, sugar-free plant-based beverage
  • Satiety trick: less liquid + ice
  • If you fancy "something delicious": cinnamon or pure cocoa (if you tolerate it well)

Gain mass / perform better

  • Base: oats or soy
  • Tip: Take it when it really helps you (post-workout or as a snack), not out of obligation.

Sensitive digestion

  • Base: Start with water
  • If you find it difficult to drink on an empty stomach: half water + half rice/almond
  • Tip: Reduce the powder a little and increase it gradually (this avoids the "it made me feel terrible" feeling on day 1)

Smoothie “snack” for the office

  • Base: plant-based drink (oat/almond/soy according to taste)
  • Texture: thicker
  • Objective: to curb your hunger to "snack on anything"

If you need a shake that works both as a light meal and a snack, the Glorious chocolate/vanilla/strawberry combination allows you to adjust it with water or plant-based milk without changing your routine.

Common mistakes (the ones that ruin the shake)

  1. Choosing a very sweet plant-based drink and then "I don't understand why it makes me hungry" (appetite spikes in some people).
  2. Blaming the protein when it's the plant-based drink that's causing the problem .
  3. Make it too liquid and expect to feel full.
  4. Do not chill : it seems silly, but a lukewarm shake worsens the taste and feel.
  5. Changing foundation every day and not knowing what suits you? Do a mini 3-day "trial".

How to apply it today (actionable steps)

  1. Choose your intention : light or snack?
  2. Choose your base : water (light) / plant-based drink (snack) / half and half (balanced).
  3. Adjust texture : start with less liquid, you can always add more.

    Find your fixed combo (for busy days):

  • Chocolate + oatmeal (creamy)
  • Vanilla + almond (mild)
  • Neutral + water (versatile)

Try the same base for 3 days in a row and decide based on how you feel (digestion, hunger, energy).

Prepare your "emergency plan" : shaker + measured dose. When you're tired, being prepared is key.

Realistic micro-story: a typical afternoon at the office, you get home and snack while you make dinner. If your mid-afternoon smoothie left you hungry, it wasn't a lack of willpower: it was a snack that didn't sustain you. Switching from water to a mild plant-based milk (or half and half) sometimes solves the problem without changing anything else.


FAQ: Real Questions

1) What is better, a smoothie with water or a plant-based drink?
It depends on your goal: water for a light meal; plant-based milk for a creamy and filling one. If in doubt, go half and half.

2) Does the smoothie made with oat milk make you gain weight?
Not on its own. It provides more energy than water, so it's a matter of fitting it into your day (and your goal).

3) Which plant-based drink is "healthier"?
Choose one you tolerate well and that fits into your routine. In general, if you want to control your sugar intake, choose versions with no added sugar and a simple ingredient list.

4) Which base goes best with vanilla vegan protein?
Almond for a smooth texture; oat for a creamier texture. It becomes lighter with water.

5) What about with vegan chocolate protein?
Oats if you want a "smoothie"; water if you want light cocoa.

6) What does Neutral mix best with?
Use water if you want versatility; use a mild plant-based drink if you want a more pleasant touch without it being overpowering.

7) Can I use hot plant-based milk?
It's possible, but it usually changes the texture and flavor. If you do it, experiment as you go: sometimes it tastes strange with certain thickeners.

8) What do I do if the shake makes me bloated?
Try this: change the base, reduce the amount, avoid taking it on an empty stomach, and observe for 2–3 days. If the problem persists, consult a healthcare professional.


Conclusion

The choice isn't moral (water "good", plant-based drink "bad"). It's practical: do you want a light smoothie or one that sustains you?
Keep it simple: water for a quick daily routine, plant-based milk for a snack, half and half when you don't want to think.

If you want that flexibility without the hassle, check out Glorious vegan protein (vanilla, chocolate, neutral, and strawberry) and choose the flavor that best suits your usual routine. And if you'd like, subscribe to our newsletter/guide for simple shake ideas that actually work in real life.
