There is a good reasoning for estimation and understanding of ideal personal weight issue because the outcome helps to determine whether the current weight is normal and identify possible deviations along with any risks related to personal health.
Usually an individual has a sense of optimal weight, with good energy levels, active lifestyle, and absence of physical discomforts.
In traditional long-held view, the optimal weight should stay at the level of personal weight of 18 year old age. Moreover, this marker should be maintained throughout one’s lifespan. Currently, this theory can hardly be seriously considered.
Furthermore, in case you do not keep your optimal weight over the 15 or 20 year period, there is no real sense of returning to that ideal. Each decade of life, the organism energy reserve is reduced by about 10%, which means about 5-6 kg. The initial calculation starts from ideal weight, and then current weight. Logically, the calculation should be based on personal ideal weight applied to your current age and lifestyle, not your 18-year old self.
Ideal body weight calculation formulas
The development of the body mass index (BMI) is the work of Adolphe Quetelet, Belgian statistician and sociologist. The scientist has greatly simplified the lives of those people who control their personal weight. However, BMI does not provide 100% accuracy in measurements, and thus should serve general investigatory purposes. For example, this tool is not suitable for athletes, because the weight of muscles is greater than the weight of fat. Furthermore, BMI calculation is not suitable for pregnant women and children.
It is worth mentioning that BMI index is typically higher in middle aged people than in younger and older age groups.
It is also considered that the average BMI index should be slightly below generally accepted standard normal weight, so that a person could have some room for improvement. However, this situation may work both ways. Thinking that personal weight exceeds normal index may cause low self-esteem, and sensitive individuals may fall into depression.
Insufficient body mass (BM), as well as excessive weight, may provoke health problems development. For example, the BM deficit in women may cause osteoporosis, irregular periods and fertility issues.
In case the calculated result indicates obesity weight range, this should not be the reason for panicking, please consider consulting your doctor. Even a slight weight loss will have a positive effect on the body and general state of health.
How to calculate ideal personal weight?
The most widely accepted method for ideal weight calculation is the Quetelet formula, known as BMI.
BMI measures the body mass (in kilograms) correlation to the square value of height (in meters).
Classification of obesity based on BMI (WHO, 1997).
|BMI: age 18-25||age 26-46||Weight|
|Below 17.5||Below 18.0||Underweight, with risk to health|
|17.5-19.5||18.0-20.0||Low underweight, no risk to health|
|23.0-27.4||26.0-27.9||Low excess weight|
|27.5-29.9||28.0-30.9||Class I obesity|
|30.0-34.9||31.0-35.9||Class II obesity|
|35.0-39.9||36.0-40.9||Class III obesity|
|40.0 and above||41.0 and above||Class IV obesity|
Example: The BMI of a woman with the height equal of 170 cm and weight of 72 kg, calculated as – 72 / 1,7 x 1,7 = 24,9. The presence of extra weight is obvious, however, obesity is not impending problem for this person. The best recommendation for a young woman would be to stop gaining additional weight, and to lose about 3-4 kilograms for optimal shape.
It is good to know that the ideal weight definition table provides the most accurate indications (168-188 for men and 154-174 for women).
For a shorter person the ideal weight equals 10% below optimum value index. The formula also varies for people who work on their fitness on a regular basis.
Ideal weight for men = (height in centimetres – 100) x 1,15.
Ideal weight for women = (height in centimetres – 110) x 1,15.
Example: Ideal weight for a woman with height of 170 cm, calculated as: (170 – 110) x 1,15 = 69 kg.
For many people this formula may remind the traditional approach based on ‘height minus 100’. This is actually the old formula improved to perfection. The previous version applied to models who exercise regularly; it did not take into consideration the body built, or individual’s age. For this reason, the formula did not apply to persons with large muscles or heavy bones, and women having remarkable body shapes, like thighs and breast areas. Therefore, the classic version of formula was upgraded to make it more realistic.
This formula was developed exceptionally to be used by women, it is not suitable for men.
Ideal weight for a woman = (height in centimeters – 100) – (height in centimeters – 150) / 2.
Example: Ideal weight for a woman, with the height of 165 сm, calculated as: (165 – 100) – (165 – 150) / 2 = 65 – 15/2 = 57,5. Thus, ideal weight is 57,5 kg!
At first sight, it may seem that this formula suggests really demanding weight standards, compared to the previous formula, and applies better to young 18 year-old females. However, it correlates with BMI indications and may work reliably. Please note that this calculation is not suitable for women taller than 175 cm.
Obesity treatment at clinic Virtus
In case your weight calculation results does not look promising and the visit to doctor concludes with obesity diagnosis, it is not the reason for paniking and getting upset. Today, many effective treatment modalities may be applied to resolve this problem condition.
The key principle in obesity treatment is comprehensive and individual approach to the therapy.
Treatment often involves experts in different areas of health – general physicians, nutritionists, endocrinologists, cardiologists as well as gynecologists. Doctors together with the patients define goals that may be realistically achieved during treatment process, provide mandatory long-term monitoring of patient’s condition, taking into consideration complete set of risk factors and secondary illnesses.
Patients go through mandatory examinations to evaluate the hormonal system, to identify levels of thyroid and pituitary hormones, and blood glucose.
Whenever necessary, the evaluation of internal organs may be performed in order to determine related effects of obesity on them.
Main tasks of obesity treatment:
- Prevention of body weight gain;
- Reduction of BMI index by 10-15% for a defined period (up to 6 months);
- Maintenance of accomplished goals for a long-term.
The last item on the list represents the most significant and difficult for implementatiion step on the way to the patient’s recovery. It requires a radical change of personal mindset, lifestyle and habits.
In addition to lifestyle changes that often fail to be sufficient, the doctor may recommend drug therapy, for extra support.
Nowadays conventional strategy implies non-medication therapy for obesity. This approach may also include nutritional therapy, physical exercises program, and behavioral therapy.
Surgical type of treatment is usually recommended to the patients with severe obesity (BMI above 35-50 kg), and only in case other methods applied do not lead to success. Surgery is also helpful to patients with sleep apnea, type 2 diabetes, hypertension and other diseases related to excessive weight.
Obesity treatment methods offered at the Virtus clinic:
- gastric banding – dividing in 2 parts of small stomach pouch and upper stomach with adjustable bands. Afterwards, a common injection regulates the size of junction between these 2 parts and related BM reduction;
- gastric bypass surgery – complete subcardial isolation using surgical stapler and connection to the distal small intestine;
- biliopancreatic diversion:
- Scopinaro modification – part of the stomach is resected, with distal part of the small intestine reconstruction for selective malabsorbtion of starch and fats.
- Hess-Marceau modification – part of the stomach is resected along its greater curve, keeping the pyloric, the ileum is connected to the upper part of duodenum.
Post-surgery effect provides significant reduction of body mass (up to 80%) with subsequent moderation of eating and food behaviors.
Selection of method depends on every specific case, with different outcomes depending on the applied method. For example, the gastric banding procedure may result in 60% loss of excessive weight, gastric bypass – about 70%, and biliopancreatic diversion – up to 75%. This is average data, while individual outcomes may vary.
Innovation in obesity treatment – temporary placement of intragastric balloon – BIB. This method is more effective than traditional non-medication treatment modalities, and safer than many surgical methods.
One of the main advantages is a long-term maintenance of achieved results. Being punctilious in following all doctor’s orders, you will forget any overweight problems.
The most intensive loss of body mass may be observed during the initial 6-months period after any type of treatment, with gradual slowing down later on. The average index for the weight loss period is 0.5-2 years. At that point in time, the patient typically accepts new models of food consumption and completes adaptation to the new diet.
