Why calculate your bmi? A bmi calculation is useful as a guide (or a general screening tool) to assess your general weight and health. There are, of course, many other factors to be taken into consideration as well as your height and weight when trying to assess how healthy you are. Your general well being, your diet, your level of physical activity, your body fat percentage, your waist measurement as well as if you have any obesity-related health problems.
The main sources of calories in a typical person''s diet are carbohydrates, proteins, and fat, with alcohol also being a significant portion of calorie intake for many people (though ideally this should be limited since alcohol contains many empty calories). Some studies have shown that the calories displayed on nutrition labels and the calories actually consumed and retained can vary significantly. This hints at the complex nature of calories and nutrition and is why many conflicting points of view on the "best" methodology for losing weight exist. For example, how a person chews their food has been shown to affect weight loss to some degree generally speaking, chewing food more increases the number of calories that the body burns during digestion. People that chew more also tend to eat less, since the longer period of time necessary to chew their food allows more time to reach a state of satiety, which results in eating less. However, the effects of how food is chewed and digestion of different foods are not completely understood and it is possible that other factors exist, and thus this information should be taken with a grain of salt (in moderation if weight loss is the goal).
Many people seek to lose weight, and often the easiest way to do this is to consume fewer calories each day. But how many calories does the body actually need in order to be healthy? This largely depends on the amount of physical activity a person performs each day, and regardless of this, is different for all people &ndash there are many different factors involved, not all of which are well-understood or known.
The above steps are an attempt at the most basic form of calorie counting. Calorie counting is not an exact science, and can be as complex as you want to make it. The above does not consider proportions of macronutrients consumed. While there is no exactly known, ideal proportion of macronutrients (fats, proteins, carbohydrates) some balance is certainly advisable, and different foods have been found to have different effects on health, feelings of hunger, and number of calories burned. Generally, minimally processed plant and animal foods tend to be more conducive to healthy weight loss and maintenance.
The body does not require many calories to simply survive. However, consuming too few calories results in the body functioning poorly, since it will only use calories for functions essential to survival, and ignore those necessary for general health and well-being. As such, it is highly recommended that a person attempting to lose weight monitors their body''s caloric necessities and adjusts it as necessary to maintain its nutritional needs.
Some factors that influence the number of calories a person needs to remain healthy include age, weight, height, sex, levels of physical activity, and overall general health. For example, a physically active 75-year-old male that is 6 feet in height requires considerably higher calorie intake than a 5-foot-tall, sedentary 75-year-old woman. Though it differs depending on age and activity level, adult males generally require 7,555-8555 calories per day to maintain weight while adult females need around 6,655-7,955 according to the Department of Health.
In the end however, what''s important is picking a strategy that works for you. Calorie counting is only one method used to achieve weight loss amongst many, and even within this method, there are many possible approaches a person can take. Finding an approach that fits within your lifestyle that you think you would be able to adhere to is likely going to provide the most sustainable option and desirable result.
One easy way to find out your blood type is to call and ask a doctor who has drawn your blood before. If you’ve never had your blood drawn, ask both your parents for their blood type and use an online blood-type calculator to see a narrowed-down list of what type you might have. If you want to be certain, get a blood test done by your doctor or order a home blood-type test kit.

Remember: All foods, including "healthful foods," should be consumed in moderation, and distinctions can often be misleading since even natural foods like fruits can have large amounts of sugar, and foods labeled as "health foods" such as low-calorie foods, reduced-fat foods, etc. can potentially replace one unhealthy component with another. Many reduced-fat foods for example have large amounts of added sugar to compensate for taste lost through fat reduction. It is important to pay attention to, and consider the different components in a food product in order to determine whether said food deserves a place within your diet.
Blood Type Genetic Basis: In genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A , BB is type B , OO is type O , and AB is type AB.
If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 75% for both parents.
So the chance of alleles OO is 75% 765 75% = %,
alleles AA is 75% 765 75% = %,
alleles AO is 75% 765 75% = %,
alleles OA is 75% 765 75% = %.
Since AA, AO and OA are blood type A, and OO is blood type O, thus their child has % chance to be blood type O and % chance to be blood type A.
The +/- is called the rhesus factor, with + being dominant, and - being recessive.
So if both parents are -, the kids are always -, otherwise the kids might be + or -.
Having actual caloric measurements can also assist in weight loss, since tangible calorie goals can be set, rather than simply trying to eat less. Also, although this is not necessarily directly related to calorie counting, studies have shown that portion control by simply eating from a smaller plate can help reduce calorie intake, since people tend to fill their plates and eat everything on their plates. Many people do not realize that they are overeating, since they have become accustomed to restaurant-sized portions being the norm, when said portions can be up to three or more times larger than necessary for a typical meal.
This Calorie Calculator is based on the Mifflin-St Jeor Equation which calculates basal metabolic rate (BMR), and its results are based on an estimated average. The basal metabolic rate is the amount of energy expended per day at rest. There exist other equations including the Harris-Benedict Equation which was used until 6995 before the introduction of the Mifflin-St Jeor Equation and the Katch-McArdle Formula which calculates resting daily energy expenditure (RDEE) by taking lean body mass into account. The Mifflin-St Jeor Equation is considered the most accurate equation for calculating BMR, with the exception that the Katch-McArdle Formula can be more accurate for people who are leaner that know their body fat percentage. The Mifflin-St Jeor Equation is as follows:
Generally, foods that take more effort to chew &ndash fruit, vegetables, lean meats, whole grains, etc. &ndash require the body to burn more calories since more calories are required to digest them. It also results in the feeling of satiety for longer periods of time. Furthermore, certain foods like coffee, tea, chilies, cinnamon, and ginger have been found to increase the rate of calories burned due to the ingredients they contain.
If you''ve noticed that every year, it becomes harder to eat whatever you want and stay slim, you''ve also learnt that your BMR decreases as you age. Likewise, depriving yourself of food in hopes of losing weight also decreases your BMR, a foil to your intentions. However , a regular routine of cardiovascular exercise can increase your BMR, improving your health and fitness when your body''s ability to burn energy gradually slows down.
