Last updated on October 26, 2023

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!

1000-calorie smoothies for weight gain - featured.

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.

When to drink 1000-calorie smoothies

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.

Not before bedtime

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]

Type: journal article

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]

1000-calorie smoothies before workouts

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.

  • If you eat 1 hour before working out, eat 1 g of carbohydrates per kg of body weight;
  • 2 hours before working out: eat 2 g of carbohydrates per kg of body weight;
  • 3 hours before working out: eat 3 g of carbohydrates per kg of body weight;
  • 4 hours before working out: eat 4 g of carbohydrates per kg of body weight.[3]

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.

How to store

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.

Benefits of drinking 1000-calorie smoothies

Here are the benefits you get from drinking the five 1000-calorie smoothies on our list:

  • Gain weight easier because all of them increase your caloric intake and keep your appetite satisfied only for a short time;
  • Increase your energy levels because all of the smoothies are rich in carbohydrates;
  • Build muscle more effectively because all of the smoothies' protein contents range between 29 g and 64 g;
  • Improve your immunity because each of the smoothies has at least four sources of antioxidants;
  • Strengthen bones because all of them contain sources of calcium, the richest smoothie offering a whopping 89% of the daily recommended intake;
  • Support your heart's health because each smoothie contains at least two sources of potassium;
  • Improve your digestion because all of the smoothies are made with at least 3 sources of fiber.

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]

Published in: Journal of the Academy of Nutrition and Dietetics

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?
