Body Mass Index (BMI) is a number that is calculated based on your height and weight. The outcome indicates whether you are at a good weight, or maybe underweight, overweight or obese. The BMI is suitable for the 'average' person. Exceptation for example is someone who does bodybuilding.

How do you calculate the body mass index? BMI is calculated by the following formula. The weight is divided by the square of the length. As an example we can take a person having a weight of 70 kg and a length of 175 cm. The calculation is 70 divided by the multiplication of 175cm. The outcome ......

There is underweight if the index is less than 18.5. The recommended weight we find in values ​​between 18.6 and 24.9. There is obesity in values ​​between 25.0 and 29.9. If there is an index greater than 30, then we call this obesity.

This calculation applies to men, women and children. For the interpretation of the BMI for children it is important to realise that they have other outcome. For example a boy at 7 years old a healthy BMI lays between 14 and 18.

The body mass index is used as a screening tool to bring potential health concerns However, it is not a diagnostic instrument. Studies to determine whether someone is at health risk, should always be performed by a medical specialist.

HEALTHY BMI FOR WOMEN

 

A healthy BMI for women is between 18.5 and 25. You can make a calculation online, if the score is lower than 18.5 it is important to gain some weight. Is the score above 25 on the other hand? Then make sure you are more careful with what you eat or try to exercise more. If your score is above 30, it is important to drop out under supervision as soon as possible, as this is a dangerous situation.

BODY MASS INDEX (BMI) AND MEASUREMENT

If you really want to calculate whether you are underweight or overweight, it is important to include your waist circumference in your calculation. First determine your BMI score using the simple and fast calculation tool and then determine your waist circumference. You can read how to do this in a few steps in the next part. It is important to first know why this measurement is so important. The BMI shows the ratio between your weight and your height. Your belly size says a lot about the fat in your body. If you are overweight and have too large a belly circumference (so too much fat under the skin and around the organs), this increases your chance of developing cardiovascular disease. Fat in other areas, such as around the hips, is not nearly as dangerous and has little effect on the risk of developing a disease. It is therefore good to calculate the fat around your waist in addition to your BMI value.

MEASURE ABILITY FOR YOUR WOMAN

Because body fat around your stomach is detrimental to your health and it is good to check this regularly, we will show you in a few steps how you can easily calculate this yourself.

  • Grab a tape measure
  • Stand up straight
  • Bare your skin
  • Locate your bottom rib with your finger
  • Slowly slide your finger forward on a straight imaginary line
  • Stop about 2 cm above your belly button
  • Apply the ribbon nicely parallel to where you came out
  • Relax and exhale completely
  • Read the result at the end of the exhalation

It is an easy measurement that you can easily perform yourself at home. For a woman, the maximum allowed value is 80 centimeters. If your waist circumference is more than 80 cm, you run an increased risk of developing health problems. If your BMI is higher than 25, it is very important to take action. Note: the values are different for men; a man may have a waist circumference of maximum 94 cm.

EFFICIENTLY REDUCES YOUR BMI AND FAT PERCENTAGE

Scientific research has shown that there is a very strong link between the amount of belly fat and the risks of contracting diseases such as type 2 diabetes, arteriosclerosis, shortness of breath, joint inflammation, cardiovascular disease, some cancers and cerebral infarction. So if you measure your abdominal circumference at home and calculate your BMI via thecalculate.nl calculation tool and these indicate higher values ​​than the permitted maximum values, it is important that you consult a doctor to look for a solution together. Several solutions are possible. An adapted diet is the basis of every treatment. In combination with plenty of exercise, this can be an efficient solution. Finally, there are reliable and recognized drugs that can work in conjunction with an appropriate diet and exercise.

WHY IS BELLY FAT MORE DANGEROUS THAN OTHER FAT?

Fat can be stored in your body in two ways. It can settle around the organs or settle under the skin. The exact location of the fat determines the effect it will have on your body. Fat around the abdominal organs and in your abdominal cavity is more active than fat cells elsewhere in the body. The fat cells around the organs produce hormones that disrupt the metabolism and can also reduce the sensitivity of body cells to insulin. Fat on the hips will cause much less damage.

PREVENT OR REDUCE VISCERAL BELLY FAT

It is clear now that too much belly fat is bad for your health. What not many people know is that even with a normal body weight you can have too much belly fat and therefore run an increased risk of health problems. With the following steps you can get rid of or prevent belly fat. We do want to mention that there are a number of factors that you cannot do much about, such as your genes and hormonal changes during the transition. You can read the factors that you can do something about below.

LOWER BMI AND BURN BELLY FAT:

Drink and eat little sugar

So-called healthy foods such as bread, fruit juice and fruit yoghurt also contain sugar. Research has shown that there is a link between high sugar intake and excess fat around the belly. Sugary drinks in particular are the culprits, as you will consume a large amount of sugar in a short time. In addition, you are much less saturated from liquid calories than calories from solid foods. So try to avoid regularly consuming sugary food and drinks.

Do not drink alcohol

Studies have shown that alcohol prevents fat burning and that excess calories are stored as belly fat. Hence the name "beer belly". If you drink more than 3 glasses of alcohol a day, you are 80% more likely to have too much belly fat than women who don't drink alcohol. Alcohol is unhealthy and large international research has recently shown that just one glass of alcohol a day is too much. It increases the risk of heart failure, stroke, high blood pressure and a tear in the aorta. All of this can be deadly.

Exercise enough (at least 30 minutes a day)

This is a piece of cake, because everyone knows that exercise burns calories. Unfortunately, people have become less active in recent decades, which is the cause of increased cases of obesity, including abdominal obesity. By exercising less or not, your weight and waist circumference will increase if you do not pay attention to your calorie intake. Hanging out on the couch and watching TV with a nice bag of chips and cola, it is great fun, but requires an active lifestyle in addition. Before you know it, your calorie intake is greater than the number of calories you burn through exercise.

Eat proteins

Getting enough protein is important to prevent weight gain. Why? Protein-rich food ensures satiety, which counteracts snacking and snacking, it speeds up digestion and leads to a lower calorie intake. Another good reason: the hormone that leads to more appetite and belly fat is less active when your protein intake is high.

Eat fiber

If you stabilize the hunger hormones and ensure a satiated feeling, you will not eat too much. By choosing food that contains a lot of fiber, you reduce the calorie intake. Watch out for processed carbohydrates, which have the opposite effect. You get less belly fat and a lower BMI by eating fiber-rich whole grains.

Get enough sleep

If you sleep poorly and too short, this can sometimes be one of the causes that you are too fat. Women who sleep 5 hours or less are 32% more likely to gain a lot of extra pounds in a few years. Therefore, ensure a good night's sleep!

TRANSITION CAN CAUSE HIGHER BMI

If you are a menopausal woman, you may have noticed that you have gained several kilos in a short time. Suddenly you can no longer eat everything you want and you start to have a tummy, even if it didn't bother you before. This is due to the hormone estrogen, which caused more subcutaneous fat around the hips and thighs during puberty, in preparation for a possible pregnancy. Around menopause there is a drop in levels of this hormone, which means that fat is stored around the abdomen, instead of around the thighs and hips. It may be genetically determined whether you suffer from this to a greater or lesser extent. It may also be because menopause starts later in life, causing more visceral fat to be stored in the abdomen. If you entered the menopause young, you may have less problems with it.

UNDERWEIGHT IN WOMEN: BMI TOO LOW

If you have a BMI that is too low, you are underweight; you weigh less than is good for your health and you may be malnourished. When do you have a low BMI and a small waist circumference? In adult women, this is with a BMI below 18.5 and a waist circumference less than 68 cm. Please note that other limits apply for people over 65 and for chronic lung diseases. If you fall under this group of women, a BMI of less than 20 for people over 65 and less than 21 for COPD patients have a BMI that is too low. A weight that is too low also entails health risks. For example, your immune system can deteriorate sharply and you can feel tired and listless. So try to gain weight. Use our accurate BMI meter at the top of this page to determine if you have lost too much weight. If your BMI is below the values ​​that are still healthy, see a doctor and determine together whether there is an eating disorder or another possible cause of your underweight.

BMI TABLE DOES NOT SAY EVERYTHING

By calculating your BMI yourself with our calculation tool, you can find the schedule for women in our BMI table. You see that your age and your height play a very important role. If you exercise a lot and you have a lot of muscle mass, we recommend that you have your BMI calculated in a professional way, because a muscular woman can be heavier because of the muscles, so that the table will show that you are overweight. It can also happen that you only lose 1 kilo from a healthy weight. If you fill in 1 kilo less with your weight, then you are suddenly in the right place. This can motivate you to exercise a little more and eat less calories, because you only need to lose 1 kilo.

Media nowadays generally give a misrepresentation of the perfect figure of women. It has now come so far, that the minimum healthy BMI value of 18.5 is considered by many women as the perfect body weight. Under the influence of the media, many women seek thereby to a body weight that is not healthy.

The problem is that your body can not function at such low values ​​completely. To be healthy, a woman should have a normal heart rate and blood pressure and that includes a healthy BMI value.

To determine the ideal weight, you need not to focus on the desire to be thin, but you have to concentrate on your health. The most healthy weight for you is perhaps not as thin as you would like.
