We outline how to gain weight healthily, with expert tips for men, women, and people with fast metabolisms who find it hard to reach a healthy weight.

Overview to underweight problems

A slim physique is often genetic. “Poor feed converters” can eat a lot without gaining weight, because their body does not store the energy it has absorbed in the form of calories in fat deposits, but uses it directly and converts it into heat.

Many underweight people want to know how to gain weight healthily. But the first rule is that it should not be too fast and should be achieved through nutrition and healthy eating. Half a kilo to a kilo per week is the recommendation for how to gain weight healthily – the same applies to those who want to lose weight, by the way. Patience is important: The body is not a machine: it can happen that, despite efforts, nothing happens on the scales for a few weeks.

How to gain weight healthily: Dangers of being underweight

Underweight people are more prone to infections and recover more slowly from illness. Often they are not resilient, tired and irritable. Long-term underweight can result in osteoporosis or hormonal changes, among other things. Girls and women who are severely underweight may have no menstrual period.

If the body is optimally supplied with nutrients through food, a slight underweight does not have to be a problem. However, those affected usually still suffer from their physical appearance.

How to gain weight healthily: how to know if you are underweight?

To assess body weight and thus underweight as well as overweight or ideal weight, doctors and nutritionists calculate the body mass index (BMI).

According to the World Health Organization (WHO), you are underweight if your body mass index (BMI) is below 18.5. From the age of 65, the limit is 22. There are separate values ​​for children and young people, depending on age and gender. To calculate your body mass index, you need your height and weight.

Formula: BMI (kg / m²) = body weight [kg] / body size x body size [m²]
This means: BMI = (weight in kg) divided by (height in meters times height in meters)

With the BMI calculator you can quickly find out whether your body weight is within the normal range.

While a BMI of less than 18.5 is considered to be underweight, this does not have to be a cause for concern in the case of minor shortfalls. A health survey by the Robert Koch Institute from 2014/2015 showed: 1.8 percent of the adults questioned were underweight according to their own information. Women were affected significantly more often than men.

However, if the underweight is below 17.5, World Health Organization speaks of pronounced underweight, which not only puts a strain on the psyche.

Being underweight is often associated with nutritional deficiencies, which can have serious health consequences. If the body lacks energy in the form of carbohydrates , protein, fat, vitamins and important minerals such as calcium and magnesium, this can cause the following symptoms:

  • decreased performance
  • slight irritability
  • Exhaustion
  • weakened immune system due to the breakdown of muscles, adipose tissue and metabolically active cells

  • Cardiac arrhythmias up to heart failure due to electrolyte deficiency
  • Muscle weakness
  • Circulatory disorders and the resulting dizziness
  • frequent freezing
  • dull, dry hair
  • dry skin and skin diseases
  • hormonal changes (lack of menstruation up to infertility is possible)
  • Stunted growth in children and adolescents

How to gain weight healthily: Causes of being underweight

There are people who, for genetic reasons, can eat as much as they want – but not gain weight. The reason for this lies in a very active metabolism: The calorie requirement of the “bad feed converters” is on average 300 to 400 calories higher than that of people who are among the “good feed converters” and tend to gain weight quickly. In addition to congenital underweight, there are other reasons for too few pounds on the scales:

  • Lack of appetite, for example due to stress, hectic rush, grief or grief
  • Diseases such as hyperthyroidism , chronic inflammatory bowel diseases such as Crohn ‘s disease or ulcerative colitis, metabolic disorders

How to gain weight healthily: the right foods to choose


The goal for underweight people should be to gain through a balanced diet — the most intelligent method for how to gain weight fast for skinny people — and for this you need to know which food to gain weight with in a healthy manner. Eating high in calories without filling up too quickly is the method, but with the right foods, and to keep an eye on how many calories to gain weight.

So keep in mind how many calories to gain a pound: 3,500 … but also don’t assume this means just eating high calorie and fatty foods. That’s not the healthy path. Under no circumstances should you randomly cram fatty foods or sweets into yourself. With a healthy nutrition plan you supply your body with all the important nutrients and still increase your overall weight. Make sure to consume foods that are high in energy density. These include foods high in carbohydrates like pasta, rice, and potatoes.

The basis for how to gain weight healthily is a wholesome diet with many nutrient-rich foods such as fruit, vegetables, whole grain products, milk and dairy products.

Your diet should contain plenty of vitamins, trace elements and minerals, such as fruits and vegetables. Increase your fat intake, for example with high-quality vegetable oils such as olive and sunflower oil or fish, so that the body does not rely on its own fat stores for energy.

High calorie and healthy foods

Give full fat products priority over light variants. You can enjoy cheese, yoghurt and cream with full fat content. Fish is a great source of fat and cold water fish such as salmon, mackerel and herring in particular contain valuable omega-3 fatty acids. Caution should be exercised with other animal fats. Too much meat and sausage are not necessarily healthy for our bodies. But you don’t have to resist a good steak or the Sunday roast. We also recommend potatoes with butter, pasta with minced meat or cream sauce and whole grain products in general. If you don’t want to do without your beloved salad, enrich it with grains, cheese cubes, oil, avocado and pickled tomatoes.

You can use a few tricks to further increase the calorie content of your food: Mix the muesli with a little creme fraiche in the morning. You can refine your soup with cream. Enjoy pasta with lots of parmesan and don’t skimp on sandwiches with the camembert.

A few diet strategies can help underweight people who are otherwise healthy to bring the missing pounds back on the scales.

  • Keep a nutrition log for about a week and calculate your current daily energy intake (for example with our food calculator ). The goal is to increase this value by 500 kilocalories.
  • The easiest way to do this is to eat several small meals throughout the day. About five to six. Then you don’t even have to stuff yourself until you feel sick.
  • Increase your weight with healthy foods. If you only eat fatty French fries, you are doing yourself and your body a disservice. You need foods that provide energy (carbohydrates) and also contain vitamins , minerals and trace elements. Of course, you also have to increase your fat intake so that your body uses less of its own fat stores for energy.
  • There are plenty of high-calorie and healthy foods. A few examples: nuts, almonds, legumes, avocados, olives, dried fruits, bananas, whole wheat bread and whole wheat pasta. High-fat dairy products are also recommended, for example in the form of potatoes with sour cream, meatballs with cream quark, carrot and pea vegetables with butter, with a whole milk shake or whole milk yoghurt in between.
  • Treat yourself to fish twice a week – ideal for example: fatty salmon – and a dish with quality meat. With vegetable and salad side dishes, which you prepare with a high-quality vegetable oil. And nibble on a few shortbread biscuits or homemade cakes. You can always have one or two granola bars or fruit slices with you for a short break.
  • Arrange the food in an appetizing way. Quark with fresh strawberries from a porcelain bowl, garnished with a peppermint leaf, is more enjoyable to eat than a bland natural quark from a plastic cup.
  • Increase the calorie content of your food. For example, you can mix a little cream under the morning muesli. You can enrich your soup with creme fraiche or a good vegetable oil such as cold-pressed olive oil. Parmesan is served over the pasta and, for example, a thick slice of full-fat cheese on the sandwich.
  • Fruit juice also provides a lot of calories: A 250 milliliter glass of apple juice has 115 kilocalories, mainly due to the sugar it contains. Here, too, you can strike. For a change, you can use many types of fruit to prepare a delicious smoothie for in between.

Regular meals

  • Cheese cubes, olives, nuts, trail mix, cream yoghurts, muesli bars, yoghurt drinks, grains, bananas and dried fruit are ideal for nibbling between meals. You can also snack on a few shortbread cookies or treat yourself to a piece of cream cake at a family birthday without a guilty conscience.
  • Even high-quality vegetable oils, nuts , cream or crème fraiche increase the energy content of soups, stews, potatoes, vegetables, pasta or rice dishes.
  • Reach for foods with a high energy density : spreads such as nut butter and pesto and high-fat fish such as mackerel or salmon.
  • For milk, yoghurt and cheese, prefer the cream and cream variants .
  • The addition of sugar, syrup, honey, nuts or cream turns desserts into delicious calorie bombs.
  • The high-energy variant choose: instead watermelon prefer bananas or prunes and cream mixture of milk and cereal cook instead of just using milk with a.

Avoid diet and light products

  • Variety on the plate and several courses also stimulate the appetite.
  • It’s best to always have something to snack on in between, such as trail mix , nuts, dried fruit or chocolate.
  • High-calorie drinking food from the pharmacy or drugstore is available in many different flavors and promotes weight gain .

Exercise helps to gain weight

Exercise is just as important in gaining weight as it is in losing weight. So that the new pounds do not turn into fat deposits, you should exercise specifically.

Regular exercise such as walking, gymnastics , cycling or swimming is important so that not only fat but also metabolically active muscle mass is added . A positive side effect: exercise whets your appetite.

Yoga , Pilates or muscle training on fitness equipment are best . If you want to gain weight, these activities are even more effective than endurance sports such as swimming, jogging, cycling or walking.

But pay attention to what you eat. If you consume too much processed sugar, for example in candy or sweetened beverages, it can have a negative impact on your health.

For how to gain weight with fast metabolism, first try to increase your caloric intake by eating regularly, eating larger meals, and choosing foods with natural sugars like whole grains or fruits.

Some women desire a faster metabolism because they think that this will make them lose weight.

Our tip: Simply refine the plate of noodles with two tablespoons of oil – then it slips better and you also fill up on valuable calories. The protein requirement is easily met with the consumption of fresh fish , meat and dairy products.

The energy requirement of every person is very different and depends on various factors – such as the basal metabolic rate, Gender, age and physical activity.
