Metabolic Age Calculator Online BMR Calculation Formula

Metabolic age is connected to calories consumed by metabolic system. It is directly dependent on BMR (Basal Metabolic Rate). BMR is amount of calories consumed by our metabolism when our body remains at rest. Its calculation is different for different genders. Here we have given the formula usually used to calculate BMR. Here can calculate you BMR after filling the details in the form given below.

Metabolic Age

Metabolic age is actually a comparison of BMR of people of similar age group. If you BMR falls in the range of average BMR of other age then your Metabolic Age will be that. So your metabolic age can be different from your actual age. To keep your Metabolic age below your actual age you need to control your weight. Weight is the only factor that you can control. Height and actual age can't be controlled by anybody. Our BMR increases till the age of 20 and then starts decreasing 100 Calorie per decade.

BMR (Basal Metabolic Rate)

The formula given below is known as Harris-Benedict formula, which was created in year 1919.
BMR for women = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age in years )
BMR for men = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) – ( 6.8 x age in year )

The above formulas are not used in modern calculations of BMR. Now we use a more accurate formula known as Mifflin - St Jeor formula, which was created in 1990. Mifflin - St Jeor formula is given below.
BMR for men = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
BMR for women = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

Metabolic Age Calculator

Metabolic Age is calculated by comparing your BMR with Average BMR of people with similar height of different age groups. If your BMR matches with a lower age group then your metabolic age is lower than your actual calender age. Lower metabolic age is considered healthy and increases your life expectancy. We tried to find a graph or chart so that you can match it to know your, but there no such thing available on net. The comparison differs according to your ethnicity as well. People living in US will have different BMR chart than those living in Asian continent.

Why Metabolic Age is not always accurate ?

Metabolic Age is calculating the BMR and then comparing it with average BMR of different age groups. But the truth is that BMR varies depending on your geographic location, lifestyle, body type, activity level and various other unknown factors. It is nearly impossible to calculate metabolic age of every person on earth using the same BMR chart. As we read about some researches of BMR on wikipedia, we found that in a research two different person with same lean body mass of 43 kg when obeserved in a test-lab reported BMRs of 1075 kcal/day and 1790 kcal/day. The difference in BMRs of those two test subjects was equivalent to running 10km. So if you want to calculate your real BMR or Metabolic Age then is better to visit a reputed medical facility.

20% Humans have hole in their Heart - Patent Foramen Ovale (PFO)

Foramen Ovale is a medical condition found in most of the newly born babies. In this medical condition there is a hole between the upper chamber of heart (i.e. right and left auricle). It is a common phenomena in babies. But this hole is closed automatically within a few weeks after birth. But one in every five person is not so lucky and his/her Foramen Ovale remain open. This medical condition is called Patent Foramen Ovale (PFO), also known as Atrial septal defect.

What happens to our body due to Patent Foramen Ovale (PFO) ?
Our right auricle contains the deoxygenated blood while left auricle contains the oxygenated blood. The hole between these two chambers of heart mixes the pure blood with impure blood. The same blood is then sent to different body parts and the same mixed blood is sent to lungs to get oxygenated. No major symptoms can be noticed of this medical condition in childhood. But as the person reaches 30's some symptoms become visible. These symptoms are:

  • Shortness of breath
  • Getting tired soon
  • Swelling in legs anf feet
  • heart palpitations
  • heart murmurs

These symptoms vary from person to person. Symptoms are more clear in people with large PFO hole, while people with small hole might never feel any symptom.
 Note: In very rare cases if a baby have both PFO and some other heart condition then blue tint may appear on skin while crying or passing stool.

Health Risks related to Patent Foramen Ovale (PFO)

  • A person suffering from PFO may live a healthy life, but chances of getting a stroke attack is more compared to a person with no PFO. 
  • In our last article betterhealthfacts.com discussed the effect of Air bubble getting injected into veins, which can cause problem is a person suffering from PFO. 
  • In some researches migraine is found connected to PFO. Those who have got their PFO corrected through surgery reported reduction in migraine.

Why do newly born babies have Foramen Ovale ?
When the arteries and veins develop in a baby inside the womb of her mother it needs blood supply. The hole (Foramen Ovale) provides more blood instantly to the heart to pump into these newly developed arteries. This Foramen Ovale does not cause any harm to baby as at that time lungs of mother are oxygenating the blood for baby. Baby's own lungs don't oxygenate the blood as baby can't breathe in the womb. As the baby is born the Foramen Ovale closes itself within a few weeks.

Patent Foramen Ovale (PFO) Diagnosis
It can be done using ECG (echocardiogram) through a bubble test performed with saline water. The doctor checks it through ECG machine if the bubble passes between two upper chambers of heart.

Patent Foramen Ovale (PFO) Treatment
PFO can be closed through surgery. There are more than 20% chances that you have got a PFO in your heart. But you don't need to go for surgery unless your doctor tell you that your PFO is causing some trouble in your body. What happens in the surgery is visible in the gif image provided here.
