Best Smoothies For Weight Gain

Are you one of those people who would like to gain some weight but often fail to do so? Simply because you do not manage to eat so much that you achieve a calorie surplus.

If this applies to you then here comes the solution. High calorie smoothies for weight gain are a little magic tool. Why this is so and which smoothies you have to drink, you will find out everything in this article. Have fun with it!

When should I drink smoothies for weight gain?

Being slightly underweight is sometimes simply a matter of disposition and need not cause any problems, provided the body receives all the nutrients it needs from the food.

But there are also people with low body weight who do not really feel comfortable in their bodies and would therefore like to gain some weight.

Lifestyle, eating habits and the way people deal with everyday stresses also have an influence on body weight. For example, Peter deliberately eats a low-calorie diet. Cathrin simply doesn't particularly enjoy food, and Daniel has a stressful job and therefore simply doesn't have time to eat enough.

Last but not least, age plays a role. Many people find it exhausting to prepare a healthy meal every day. In the case of older people, this is often accompanied by very specific obstacles: Dental problems, medications, a variety of illnesses and a declining sense of taste have a lasting impact on appetite.

Important Note!

If someone loses weight quickly, although he eats normally, feels weakened or other physical or psychological changes occur, then a doctor should be consulted in any case to clarify the cause.

However, if diseases such as those of the gastrointestinal tract or metabolism have been ruled out, the failure to gain weight is often genetic. For some people, the body is simply not designed for weight gain.

Underweight is at the same time always the expression of an energy deficit. This means that the body consumes more energy than it receives. The result: the body loses weight in order to cover its energy requirements.

Even people who do a lot of sports and workouts and are actually fit and healthy can be too slim, simply because they consume fewer calories than they burn with sports. High calorie smoothies for weight gain can help you to boost your energy.

At what point is one underweight?

Body measurements and the body mass index calculated from them are a good way of objectively assessing body weight.

According to the definition of the World Health Organization (WHO), people are considered underweight if their body mass index (BMI) is below 18.5.

Between the ages of 65 and 70, this limit rises to 20, after which a BMI below 22 is considered underweight.

BMI (kg/m²) = body weight [kg] / height x height [m²]

How skinny people gain weight fast?

To gain weight healthily and quickly, it is especially important to eat a lot of protein. A protein-rich diet helps to build muscle mass and not to build up undesirable fat deposits.

For healthy weight gain, you should eat about 1.5 - 2.2 grams of protein per kilogram of body weight per day. High calorie smoothies for weight gain are very suitable for this purpose and can help you to increase your weight quickly and easily.

These so-called weight gainers are useful for achieving a calorie surplus. Even for petite women who find it difficult to achieve a calorie surplus, gaining weight with protein shakes in combination with a healthy diet can be a successful and effective solution.

When you think of foods for gaining weight, fatty foods quickly come to mind. However, by doing so, you only gain weight in an unhealthy way. When you increase your weight the wrong way, you gain fat rather than muscle.

If you'd rather gain weight in the form of muscle, the best way to do that is with healthy food. Here are some foods for weight gain that are great to pair with smoothies:

  • Nuts & nut butters (peanut butter, almond butter, peanuts, walnuts, cashews, etc.)
  • Potatoes and starches (oats)
  • Healthy fats and oils (coconut oil, olive oil, avocados)
  • Full-fat yogurt, milk or natural alternatives like almond milk or oat milk


For healthy weight gain, do not reduce your normal diet of healthy foods and take the high calorie protein shakes in addition.

Which Fruits Should You Use In High Calorie Smoothies?

Fruits and vegetables are not only healthy, but sometimes very high in calories. Reach for avocados, bananas, soybeans and olives. They contain many unsaturated fatty acids, which the body urgently needs.

The right ingredients to make weight gainers yourself

Ideally, weight gainers consist of about 60 percent carbohydrates and 20 percent each protein and healthy fats.

Perfect ingredients are therefore oat or spelt flakes, honey, fruit, nut puree, nuts, coconut oil, high-quality oils, flax seeds or chia seeds, seeds such as sunflower seeds, and quark or whey protein. Tasty smoothy bowls can also be a great alternative where you can use many of the above ingredients. With some superfoods they are also more healthy.

As a base you should use milk. Milk not only provides extra calories, but also provides a creamier consistency. If you have to or want to avoid cow's milk, you can of course also take a natural milk substitute such as rice, almond or oat milk.

Here is a simple recipe from the family of protein smoothies for weight gain without protein powder:
