People chasing body goals are mostly imagined sweating buckets on a treadmill while their stomachs growl. However, not everyone strives to shed pounds and trim waistlines. For some, the idea of gaining weight can be equally cherished and challenging. If you can relate, these special weight gain smoothies are all yours to shake up.

Do smoothies help you gain weight? Weight gain smoothies provide an effortless and effective way to increase your calorie consumption, which is crucial to bulk up. High-calorie smoothies can be high in micronutrients and minerals, too. Various fruits, greens, seeds, and syrups can help you in the process.

Best Weight Gain Smoothies

Should I Drink Smoothies to Gain Weight?

There are several reasons to look for a bulkier build. You may want to enhance your aesthetics, get stronger, or move into a new weight class for sport. Particular medical conditions also warrant diet changes to counter unintentional weight loss. Low body weight can compromise health – including cardiorespiratory fitness, mental sharpness, and immune response. 

Having smoothies for weight gain can help with these goals. You can control the taste, quantity, frequency, and nutritional value of each drink. Following are some other benefits to sip your way to a fuller figure.


The latest reviews of must-have home gym training equipment, apparel, and supplements that will enhance your performance and bring you new results.

1. High on Calories

Increasing daily calorie intake is a surefire recipe to gain weight. Aim for a surplus of 300-500 calories per day for a gradual and sustainable increase in total body mass and weight. Don’t think it’s a lot of snacks and meals. One of these high-calorie smoothies will likely be enough.

2. A Healthy Choice

A weight gain routine requires as much discipline as any other body composition goal. You can’t stuff cakes, pizzas, and soda drinks to the gills. Junk foods are a leading cause of belly fat. Include nutrients into your diet, not just empty calories, with the help of smoothies. 

3. Meal Replacement

Eating two or three large meals may make you feel full and satisfied for the day. But they may not supply as many calories as multiple smaller meals. In fact, studies have found that hunger and desire to eat increase with higher meal frequency. You can replace intermittent or post-workout snacks with weight gain shakes.

4. Quick and Easy

Last but not least, healthy weight gain smoothies allow you to hit your planned energy quota conveniently. You can enjoy them on the go or at your desk. You don’t have to sit for a lengthy meal. A typical recipe takes about five minutes to prep and even less to chug down.

Which Smoothie Is Best for Weight Gain?

Once you’ve settled on a dynamite combo of ingredients that tastes good and gentle, make sure it checks off the following criteria:

  • Over 400 calories per serving
  • A good distribution of macros
  • Full-fat milk, yogurt, nut butter
  • Fresh fruits and veggies
  • No added sweeteners or flavors

What Makes the Best Smoothie for Weight Gain?

There are three macronutrients: carbohydrates, fats, and proteins. You can customize the ratio in your high-calorie drinks for weight gain. 

  • Carbohydrates carry 4 calories per gram. They exist in the form of sugars, fiber, and starches. For highly active/athletic individuals, 45-65% of your calories should come from carbs. They’re abundant in milk, beans, fruits, and vegetables.
  • Proteins also have 4 calories per gram. They are critical for several bodily functions and are found in meat, eggs, and lentils, for example. The minimum recommended daily quantity is 0.8g/kg body weight.
  • Fats have the most calories at 9 per gram. Healthy fats should replace saturated ones to reduce CVD risk. Your fat intake can be the remainder of total daily calories after calculating protein and carbohydrate intake. You’ll find them plenty in oils, seeds, and avocado.

Top-Rated Smoothie Recipes for Weight Gain

We’ve selected these five weight gain smoothie recipes for you. Loaded with antioxidants and minerals, they boast strikingly different ingredient lists. You’ll surely love one or more.

1. Peanut Butter Choco Mix – High Carb Protein Smoothie

Prep Time: 5 min

Building a high-protein smoothie is possible with these whole ingredients. You won’t need a protein powder separately. Peanut butter is everyone’s favorite because of its unique texture, taste, and – more importantly – dozens of calories in a single spoon. We’ll use a banana and chestnuts for this one.

drinking supplement drink


  • 1 medium banana
  • 2 tbsp peanut butter
  • 2 tbsp unsweetened cocoa powder
  • 30g dried nuts (chestnuts, almond, etc.,)
  • 1 cup soy milk (or any other non-dairy milk to keep fats in check)


Mix all these ingredients in a blender until smooth. Throw a couple of ice cubes in the mix to do away with the slimy texture and make it more drinkable. Enjoy! Try to stock up on frozen bananas in a zip-top bag.

3. Green and Gut-Healthy – High Protein, High Fiber Smoothie

Prep Time: 10 min

Although we avoided animal-based items for the first two smoothie recipes for weight gain, this one too, is vegan and also green. We’ll use a combination of green fruits and veggies to spike prebiotics and dietary fiber. If you don’t want to get as much protein, toss out the powder.


  • 1 cup/30g baby spinach
  • 1 medium celery stalk
  • 1 medium Granny Smith apple
  • ½ medium banana
  • ¼ avocado, pitted and sliced
  • 1 scoop/50g of plant-based protein powder (optional)

4. Oats Energy Blast – High Carb Breakfast Smoothie

Prep Time: 5 minutes

Oats are crazy nutritious, containing carbs, fibers, fats, and proteins along with loads of vitamins and minerals. The protein – avenin – is similar to wheat gluten. But oats are safe for gluten intolerant people. This simple four-ingredient recipe qualifies for weight gain shakes of maximum calories.

preparing for workout


  • 100g rolled oats/oatmeal
  • 1 large banana
  • ½ cup/100ml whole milk
  • 24 whole kernels of almonds
  • 1 cup water


Oats and almonds drive the calorie and carbs count, whereas banana (being a fruit) makes it a smoothie. Water will thin out the mixture. Pulse the blender to break up the nuts before blending everything.

5. Pink Berry Shake – High Fat Protein Smoothie

If you’re looking for rich-flavored smoothies to gain weight besides peanut butter recipes, you can’t do better than this strawberry shake. Turn everyday into a cheat day with tasty weight gain smoothies, like this one. Try to limit high-fat shakes to one glass a day.

  • ½ cup strawberry ice-cream

Why Is It Better to Make Smoothies Yourself?

Building high-calorie smoothies for weight gain at home is a good and fun idea. First of all, there are no strict rules. You can influence the recipe, composition, and frequency according to your needs. Some very effective and clean pre-made formulas are on the market, but the search can be long and annoying. Homemade high-calorie shakes for weight gain don’t take much time to prepare. You can down it within a few minutes and be on your way.

1. Tips for Making the Best Smoothies for Weight Gain Yourself

  1. You only need a blender and a curated selection of energy-filled ingredients at your hand. Ensure the bulk of calories are coming from carbohydrates. Hit the USDA database to get nutritional facts of any item.
  2. Protein is a must for smoothies. A higher intake range of up to 2g/kg is advised for bodybuilding. Feel free to rely on whey or vegan protein powder. Supplements can enhance muscle mass and performance.
  3. There are always alternatives. Peanut butter can be swapped with other nut butter. Also, non-dairy milks are almost perfect substitutes for each other. Use flax, chia, or pumpkin seeds if hemp seeds aren’t available.

Our Recommended Weight Gainer – Transparent Labs Mass Gainer

tl mass gainer

Transparent Labs Mass Gainer is an exceptional Protein Series formula to gain weight. It’s a complete package to mix with a pint of milk to get about 750 calories. You’ll get at least 50g of whey-based protein and 100g of carbohydrates.

The difference is due to vanilla and chocolate flavors. Both carry no artificial additives. Fats are balanced at 18% DV. However, the milk will increase the fat content. Fill two scoops for one serving. There are fifteen servings in a tub, each setting you back over $5. It’s expensive but effective.

Our Recommended Protein Powder – Future Kind Vegan Protein Powder

promix protein

Future Kind Vegan Protein Powder is your best bet for protein-enriched weight gain smoothies. Its chocolate flavor contains hemp and pea proteins, ideally complementing each other in structure and taste as well. Unfortunately, you won’t have more flavors to try. Hemp isolate is a complete source of protein, unlike most plant-based options. It has a light scoop of 30g, costing $2 each. It brings a whopping 20g of protein and 120 calories to top off your smoothies. The 67% protein content by weight is impressive for a vegan formula.


How Can a Skinny Person Gain Weight Fast?

A skinny person can eat nutrient-rich, high-calorie meals more frequently throughout the day. Trying shakes and smoothies for weight gain helps spike calorie intake. Target a surplus of about 500. Don’t ignore strength training. It’ll ensure that lean muscles account for weight changes, not fat. However, long-term overfeeding increases fat mass. Therefore, aim for clean bulking.

Are Berry Smoothies Good for Weight Gain?

Berries are a good source of antioxidants, fiber, potassium, and vitamin C. They’re a low-fat, low-carb choice. They’re also low in calories. A typical one-cup serving is about 80 calories, depending on the type of berry. Moreover, they taste good. Many weight gain smoothie recipes will benefit from these sweet and small fruits. 

Which Fruit Is Best for Weight Gain?

Many tasty fruits out there can assist you on your weight gain journey. Bananas, avocados, mangoes, and dates are some excellent examples.  

Does Banana Help in Weight Gain?

It certainly can! A medium-sized banana supplies 105 calories, 27g carbs, and 1g fat. It also carries multiple antioxidants and phytonutrients for healthy bodily functions. It goes with every shake and helps create a smooth and creamy texture.


High-calorie smoothies can do wonders for your bulking plans. They can effortlessly raise your daily intake of calories and nutrients, assisting a healthy weight gain over time. We hope you liked these recipes for weight gain smoothies and try one or two. Coincide shakes timing with your meals, such as breakfast, lunch, or before bedtime. Make sure to keep up with regular strength training to promote lean, fat-free mass over time.
