Quick Overview
Our five 1000-calorie smoothies are rich in proteins, can help you gain weight and muscle mass, and save you time.
In the recipes, we included some of the most frequently used ingredients in 1K smoothies, like oats, milk, or protein powder.
As proof of these smoothies' usefulness, research shows smoothies with 1000 calories are some of the most popular among high-calorie smoothies.
After all, one such smoothie can replace 1-2 average meals.
Let's find the best 1000-calorie smoothies for you and how you can add them to your diet!
If you feel smoothies with just a few hundred calories are insufficient for your caloric needs, it's time to step up your smoothie game by adding 1000-calorie smoothies to your diet.
Many people who want to buff up make this transition.
Personally, these "grand" smoothies are one of my main options on days when I don't have time to eat enough calories.
As further evidence, smoothies at the 1000-calorie mark are the most popular type of high-calorie smoothies among people looking to gain weight.
According to our research on worldwide Google data, 1000-calorie smoothies are almost twice (180%) as popular as 2000-calorie smoothies, and nearly eight times (762%) more desired than 500-calorie smoothies.
Yet, to make 1000-calorie smoothies optimized for gaining weight and/or building muscle, blend ingredients that will provide an adequate ratio of macronutrients (proteins, carbs, and fats).
To get that task off your back, we summoned our extensive experience in making high-calorie smoothies and dusted our guide for creating weight gain smoothies.
The result?
We came up with five 1000-calorie smoothie recipes. Let's explore each of them.
1003 calories
The 1000-Calorie Avocado Banana Smoothie has so many calories because it has avocados and bananas, two of the fresh fruits with the most calories, at its core.
In terms of macronutrients, this smoothie will load you with plenty of muscle-building proteins, energizing carbohydrates, and healthy fats, many of the latter coming from avocado and cashews.
If you're a vegan, you can make this smoothie dairy-free by replacing whey protein powder with a plant-based protein powder, like the ones made from rice or peas.
The smoothie has a banana taste that's tempered by avocado's more neutral flavor. You'll also feel some notes of coconut.

1033 calories
The nutrient-dense 1000-Calorie Chocolate Sunflower Seed Butter Smoothie is the smoothie with the most proteins on this list of "grand" smoothies tailored for weight gain. Most of the smoothie's protein content comes from rice protein powder, but the sunflower seed butter and the oats also contribute.
Besides, this vegan smoothie is low in fats and filled with energizing carbohydrates.
In terms of taste, banana and honey's sweetness merges with the bitter notes of cocoa and sunflower seed butter's earthy aroma.

Arguably the most delicious smoothie in our recipe round-up is this 1000-Calorie Tropical Smoothie. The best thing besides its flavor is its macronutrient profile.
This bulking smoothie has a tad bit over 40 g of protein, plenty of carbohydrates, and some healthy fats as well.
Regarding the smoothie's flavor, you will feel mango, pineapple, and banana aromas. Hey, it's called tropical for a reason.

If you love bananas, you will enjoy our High-Calorie Banana Smoothie, also known as the Gorilla Smoothie.
Although it has 989 calories, we can still consider it a 1000-calorie smoothie since it's only 11 calories away from the mark.
In terms of macronutrients, the smoothie is loaded with proteins and carbs while being low in fats.
Did we mention it's made without protein powder?
Flavor-wise, the smoothie has a strong banana flavor that's calmed down by subtle notes of oats and cashews.

This vegan High-Calorie Fruity Green Smoothie delivers 1032 calories and 29 g of protein despite the fact it's made without protein powder.
Moreover, this smoothie is loaded with healthy fats, vitamins, and minerals coming from the plethora of fruits, vegetables, seeds, and nuts found in its composition.
In terms of taste, the smoothie has a crisp flavor with subtle coconut nuances accompanied by earthy notes coming from seeds and high-calorie nuts and nut butters.
From Unfold community
If you are like one of our YouTube followers who "can't handle the texture" of bananas, replace bananas with 1 additional mango or about 300 g (10.6 oz) of pineapple.
Also, you can make the smoothie without bananas. You'll lose 210 calories, but hey, you still end up with a smoothie of 822 calories.
Overall, this vegan smoothie has received positive feedback from our followers. Over 49 people liked this recipe on YouTube and TikTok.

You can drink smoothies with 1000 calories most times of the day, but you should schedule them at least 3 hours before bedtime and not too close to the start of your workouts.
A Brazilian study exploring the food-sleep relationship suggests that "intake of high fat and carbohydrate foods" in the 3 hours preceding your bedtime makes it harder for you to fall asleep.[1]

The smoothies on this list are not high in fats but they have plenty of carbohydrates, so you should avoid scheduling your 1000-calorie smoothie of choice 3 hours before hitting the sheets.
Another reason why you should avoid 1K smoothies before sleeping is a better sleep.
American researchers studied the connection between bedtime eating or drinking and waking up at night. Their results show that eating or drinking further away from bedtime will make you wake up less often.[2]

If you want to use 1000-calorie smoothies as energy sources for your workouts without finding yourself bloated at the start of your training session, you should first do some simple math. This is what Marie Dunford, PhD, RD, and J. Andrew Doyle recommend in their book Nutrition for Sport and Exercise.

Now, don't get scared about the numbers above.
To find out how many hours before your workout you should drink your 1000-calorie smoothie, all you need to do is apply this formula:
Smoothie's total carbs ÷ Your bodyweight in kg
Just divide your smoothie's total carbohydrates by your bodyweight (in kilograms). If the result is closer to one, drink your smoothie 1 hour before your workout. If it's closer to two, drink it 2 hours before your workout. And so on.
We suggest drinking your 1000-calorie smoothies right after blending them to enjoy their best taste. Yet, in case 1000 calories are too many for you in one go, you can safely store the smoothie in the fridge for about 24 hours in something like a shaker bottle or a jar.
Here are the benefits you get from drinking the five 1000-calorie smoothies on our list:
In addition to the health benefits above, drinking 1000-calorie smoothies will save you time because they are easier to make than an equivalent meal.
Consider this...
The typical lunch or dinner meal for a woman, according to a study on the energy of ordered meals, has 570 calories. For men, the average meal would have 712 calories.[4]

Therefore, a 1000-calorie smoothie can replace almost 2 average meals for women, giving them around 175% more calories than their average meal. Then, it's no surprise that smoothies and shakes are one of the most effective foods for females who want to gain weight.
When it comes to men, a 1K smoothie provides 140% more calories than their typical meal.
More calories in less time. Sounds like a good deal, doesn't it?
