Although some consider protein powders a convenient source of muscle-building proteins and a staple ingredient in smoothies, others trying to gain weight may prefer to make their blends without these powders, which can be expensive and don't fit everybody's dietary preferences.
Yet, it's getting harder and harder to find smoothie recipes that aren't made with some type of protein powder.
As proof, our research on Smoothie King, one of the world's largest smoothie chains, shows that 76% of the smoothies on their menu contain protein powder.
Therefore, smoothies without protein powder have become a minority.
But don't worry.
After reviewing our list of high-calorie smoothies, we selected 6 smoothie recipes that include a variety of natural sources of protein instead of protein powders. And the best thing? Since they don't contain protein powder, which tends to add a nutty taste if unflavored, all of these recipes taste delicious.
Let's explore the recipes, ranging from 445 to over 1000 calories and reaching up to 42 g of proteins.
This High-Calorie Banana Chocolate Kale Smoothie, resulted after we modified the ingredient quantities in one of the recipes shared by tennis champion Novak Djokovic, can help you gain weight and build muscle because it has over 400 calories and proteins coming mainly from almond butter.
In terms of flavor, the smoothie has a bittersweet but refreshing taste thanks to the crispness of the kale, a superfood, the bittersweet aroma of the chocolate syrup, and the sweet savor of bananas.

Another blend designed for weight gain and inspired by Novak Djokovic's diet is this High-Calorie Mango Banana Smoothie, which is rich in antioxidants, has 651 calories, and contains proteins coming from almond butter.
When it comes to its flavor, the smoothie has a balanced taste because the sweetness of the mango and the banana complements the tanginess of the kale.

The next step after picking your favorite powderless protein smoothie designed for weight gain is to schedule its consumption.
The best time for drinking this type of smoothie is anytime but not too close to your bedtime, workouts, or other high-protein meals.
Consume smoothies before your workouts (but not too close to them) to fuel your body or after your workouts to replenish lost energy and help your muscles recover and grow. Also, because they won't satisfy your appetite for too long, you can serve smoothies between meals to boost your caloric and protein intake.
Yet, since not all smoothies are created equal, you should schedule them according to their calories and macronutrients, as explained below.
First of all, you should split any smoothie that has too many proteins for your body weight into multiple servings.
According to a scientific review on daily protein distribution, the maximum number of proteins you can eat and process effectively in one sitting is 0.55 g per kg of body weight.[1]

Published in: Journal of the International Society of Sports Nutrition
For example, if you have 80 kg (176 lbs), you shouldn't eat more than 44 g of proteins in one sitting.
Therefore, before scheduling your next weight gain smoothie, look at its nutrition facts and see how many proteins it has. If it's bigger than the maximum number of proteins you can process effectively in one sitting (0.55 g * your body weight in kg), then split the smoothie into multiple servings scheduled across your day.
If you want to use smoothies as pre-workout fuel, you should follow some guidelines to not feel bloated during training.
According to evidence related to the best timing of pre-workout meals, you should drink your smoothie between 30 minutes and 2 hours before your workout to optimize your body's protein levels for building muscle.
But you should also pay attention to the number of carbs in your chosen smoothie. Although they're energizing, too many carbs are going to slow you down.
To calculate how many hours before your workouts you should drink your smoothie, whether it's a 1000-calorie smoothie or a smaller one, one idea is to follow the model recommended by Marie Dunford, PhD, RD, and J. Andrew Doyle in their book Nutrition for Sport and Exercise.

Here is the simplified formula:
Smoothie's total carbs ÷ Your body weight in kg
Just divide your smoothie's total carbohydrates by your body weight (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.
Also, you shouldn't plan your high-calorie smoothies before bedtime. This is because it will have negative effects on your sleep quality.
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.[3]

Since smoothies are generally based on fruits and/or vegetables, they are usually rich in carbohydrates, just as the recipes on our list. Therefore, you should avoid scheduling them in the 3 hours before it's time to hit the sack.
Another reason why you should avoid weight gain smoothies before going to bed is a better overall 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.[4]

We recommend drinking your smoothies right after blending them to enjoy their finest taste. However, in case you'd rather postpone them, you can safely store the smoothie in the fridge for about 24 hours in something like a shaker bottle or a jar.
When preparing homemade protein smoothies, you can replace protein powder with proteins coming from whole food ingredients, like these:
If you're looking to increase your body mass with other high-calorie liquids made without protein powder besides smoothies, you can find some tasty alternatives on our lists of calorie-dense shakes and weight-gain drinks.
