Whether you’re new to making smoothies or looking for ways to modify your existing recipes to aid in weight gain, this guide and collection of recipes will help.

The Science Behind Weight Gain

At its core, weight gain is a simple equation: consume more calories than your body burns. However, the sources of these calories matter. Protein, carbohydrates, and fats all play a critical role in gaining weight.

Proteins are the building blocks of our muscles, and consuming sufficient amounts is essential, especially if you’re engaging in strength training.

Carbohydrates provide the energy our body needs to function and carry out daily activities. Finally, fats play a crucial role in hormone production and can be a dense source of calories.

In the context of smoothies, fruits provide natural sugars (carbohydrates) and important micronutrients. When combined with other high-protein or high-fat ingredients, these smoothies can become a balanced addition to support healthy weight gain.

Best Fruits for Weight Gain Smoothies

When it comes to weight gain, not all fruits are created equal. Some fruits are higher in calories and nutrients than others, making them an ideal choice for weight gain smoothies.

  • Bananas: Bananas are rich in carbohydrates and potassium. Their creamy texture also help enhances the smoothie’s consistency.
  • Avocados: Avocados are a rich source of healthy fats and an array of vitamins including C, E, K, and B-6. They are calorie-dense and add a rich and creamy texture to your smoothie.
  • Mangoes: A popular choice among high-calorie fruits, mangoes contribute significantly to the caloric content of your smoothie. They also come packed with essential vitamins and minerals like vitamin C, A, and potassium.
  • Berries: Although berries like strawberries, blueberries, and raspberries are not as calorie-dense as other fruits on this list, they still make an excellent addition to smoothies due to their high antioxidant and vitamin content.
  • Coconut: Coconuts are a great source of healthy fats and are calorically dense, making them beneficial for weight gain. The natural sweetness and creamy texture of coconut can also significantly enhance the richness of your smoothie.

Other Ingredients for Weight Gain Smoothies

While fruits are a great start, there are other ingredients that will give your weight gain smoothie an extra calorie boost.

  • Nut Butters: Almond butter, cashew butter, and peanut butter are all good sources of healthy fats and protein. They can significantly increase the caloric density of your smoothie.
  • Protein Powder: If you’re struggling to get enough protein in your diet, consider adding a scoop of your favorite protein powder to your smoothie. There are various types available, including whey, soy, casein and plant-based proteins.
  • Yogurt: Full-fat Greek yogurt is a fantastic source of protein, calcium, and probiotics. It can help improve the texture of your smoothie.
  • Seeds: Flax seeds, chia seeds, and hemp seeds are rich in healthy fats, fiber, and protein. They’re a great addition to any smoothie as they are not overpowering.
  • Oats: Oats are an excellent source of complex carbs and fiber. They also provide long-lasting energy when used in a pre-workout smoothie.

Healthy weight gain involves more than just increasing your caloric intake. The quality of the food you eat is just as important, if not more so.

Your goal should be to gain weight in a manner that enhances your health, not compromises it.

That’s where fruit smoothies come into the picture. They are a delicious and nutritious way to add extra calories to your diet.

Moreover, they are easily customizable, allowing you to incorporate various nutrient-rich ingredients that support weight gain and overall health.

Remember, the goal is not just to gain weight but to nourish your body with essential vitamins, minerals, proteins, and healthy fats. This is important for your overall well-being and energy levels.

Making and consuming smoothies can be a fun and effective strategy for weight gain. Here are some tips to maximize their effectiveness:

  • Use Full-Fat Products: When adding dairy or plant-based alternatives, opt for full-fat versions to boost the caloric content.
  • Post-Workout Smoothies: Consuming your smoothie after workouts can be beneficial. Your body is in recovery mode and can use the nutrients more efficiently, promoting muscle growth and recovery.
  • Smoothies as Supplements: Smoothies should not replace your meals but be consumed in addition to your regular diet. They are a great way to supplement your calorie intake.
  • Get Creative: Mix and match different fruits, nut butters, seeds, and other high-calorie ingredients to keep things interesting and cater to your taste preferences.

Frequently Asked Questions (FAQs)

Can I gain weight by just drinking fruit smoothies?

While smoothies can contribute to weight gain, they should not be the sole strategy. It’s essential to maintain a balanced diet and regular exercise routine.

How many smoothies should I drink a day to gain weight?

This depends on your individual caloric needs. Start with one smoothie a day or every second day as an addition to your meals, then adjust based on your progress and nutritional needs.

Are homemade smoothies better than store-bought ones for weight gain?

Typically, yes. Homemade smoothies allow you to control the ingredients and their quantities, making it easier to tailor the nutritional profile to your needs.

Store-bought smoothies can often contain added refined sugars or preservatives, which don’t tend to align with healthy weight gain.

What’s the best time of day to drink high-calorie fruit smoothies?

There’s not a definitive best time, as it largely depends on your lifestyle and routine. However, having a smoothie after your workout is great time as your body is primed to absorb nutrients for muscle repair and growth.


Gaining weight in a healthy way is just as important as losing weight, and fruit smoothies can be an excellent tool in your weight gain journey.

By combining high-calorie fruits with other nutrient-rich ingredients, you can create delicious, balanced smoothies that can help you reach your weight gain goals.

Remember to consume these smoothies in addition to your regular meals, opt for full-fat products, and enjoy your smoothies post-workout to maximize nutrient absorption. Happy blending!
