Using Bmr And ‘daily Caloric Need’ To Gain Or Lose Body Weight

Tuesday, January 11th, 2011

Let me start off by briefly going over some very basic, fundamental information about the constituents of the foods that we eat and how our bodies are able to utilize the calories, carbohydrates, proteins, and fats that make up these foods.

All of the foods that we eat, including meats, vegetables and fruits are made up entirely of either one or more of the following 5 fundamental nutrients:

Proteins
Carbohydrates
Fats
Ethanol (Alcohol)
Vitamins & Dietary Minerals
Fiber

Of these 6 components, the first four in the list all contain calories.  Calories are basically the amount of energy stored within each of these nutrients.  Calories are needed by the human body to fuel metabolism.  Metabolism is the process responsible for turning food into the energy needed to support life.  The two basic metabolic pathways responsible for the conversion of calories to energy are the anabolic pathways and the catabolic pathways.   Catabolism refers to the set of metabolic pathways in which molecules are broken down into smaller units causing a small amount of energy to be released in the form of heat, while the remaining energy is used to drive the synthesis of an energy transport molecule called adenosine triphospate (ATP).  ATP is basically a molecular form of stored energy and allows the transfer of chemical energy from one metabolic process to another.  The metabolic processes that use ATP as an energy source also convert it back into its precursors allowing it to be recycled continuously.  The ATP, created during catabolism, is then available to fuel the processes within the other metabolic pathway - the anabolic pathway.  Anabolism is the set of metabolic pathways reponsible for the construction of new molecules from smaller units.  Anabolism is responsible for bone mineralization, cell differentiation and growth, and muscle growth.

Regulating calorie intake can affect both gaining body weight and losing body weight.  Generally consuming more calories than the amount used by the bodies’ current metabolic needs results in body weight gain.  Consuming fewer calories than the amount needed by the body to fuel its current metabolic needs results in weight loss.  For someone interested in attempting to either gain or lose weight it is very useful to know how many calories are needed, on average, to fuel the bodies current metabolic needs.  I will refer to this number as the ‘daily caloric need’.  To determine the ‘daily caloric need’ it is necessary to first ascertain what is called the BMR or ‘basal metabolic rate’.  The human body burns calories 24 hours a day, even during sleep.  The basal metabolic rate, which can be estimated by using the very simple formula you see below, is the number of calories the resting body would burn if absolutely no activity were performed in a 24 hour period.

Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) – ( 4.7 x age in years )

Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) – ( 6.8 x age in year )

Now that the BMR is known, applying an activity multiplier to this number will result in a fairly accurate estimate of the number of calories needed by the metabolism to fuel typiical activity level and basic metabolic processes.  Here I am using the Harris Benedict Formula.

To determine the ’daily caloric need’, multiply the BMR by the appropriate activity factor, as follows:

If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9

Now that the ’daily caloric need’ is known, it is very easy to figure out how many additional calories need to be consumed to gain weight or how many fewer calories need to be consumed to lose weight.  For the person trying to gain weight, suffiiciently increasing calorie consumption over the ‘daily caloric need’ will cause body weight gain.  A pound of body weight is roughly equal to 3500 calories, so if the goal is to gain one pound of body weight a week, 3500 excess calories should be consumed during the course of one week.  Take 3500 and divide by 7 (days in a week), and the resulting 500 is the number of extra calories that need to be consumed each day to reach this goal.  The composition of the food calories consumed, ie. the amounts of proteins, carbohydrates and fats, is also very important to promote lean muscular gain.  See the article, Eating: Lean, Muscular, Weight Gain.  While eating excess calories will invariably produce weight gain, it is important to remember that the goal is to gain ‘muscular’ weight, not to increase storage of body fat.  When using this method to gain weight it is highly recommended that considerably more intense exercise be performed to promote an increase in muscular weight.

For someone trying to lose weight, the same basic principles apply.  3500 calories is roughly equal to one pound of body tissue so therefore, limiting calorie consumption to 3500 below the ‘daily caloric need’ in one week should produce weight loss close to one pound a week.  That’s 3500 divided by 7, giving a result of 500.  So, 500 fewer calories than baseline (calculated above), need to be consumed each day to reach the goal for the week.   Here again, the composition of the food calories eaten during this time is very important.  See the article, Eating: Lose Weight & Retain Muscle.  Unfortunately reducing calories can also negatively affect the metabolic rate, slowing it down, and limiti the amount of weight that can be lost.  To compensate for the slowing metabolism, an additional 30 to 45 minutes of cardio-vascular exercise, added to the daily exercise routine, will help stimulate metabolism and increases the number of total calories burned.   At a body-weight of 175 lbs., 30 minutes of cardio exercise will burn between 300-500 calories.   This increases the total daily caloric deficit to 800-1000 calories and the weekly deficit to 5600-7000.  At 7000, that’s going to be very close to 2 pounds of body-weight lost each week.

Now it’s important to remember that this is merely a guideline and many, many other factors can, and will produce great variation among the individual results realized through the use of this approach.  Genetic factors, general health, a prior history of exercise experience and poor diet or nutrition can all contribute to a decrease in the effectiveness of this technique.  It truly is not possible to emphasize enough the importance of consuming good high quality protein, adequate amounts of long chain complex carbohydrates and at least some omega-3 fatty acids, particularly while attempting to either lose or gain weight.  More about this later.

Generic Drugs Are Need Of Time

Thursday, May 13th, 2010

Everybody knows that economic recession is hitting the world badly and thus every one wants to save their money in whatever way possible. One most essential thing that every one needs is the medicine, whatever it may be to survive and fight back the disease, we always need medicines. But, nowadays ever medicines have become so expensive. So many people tend to avoid them and land up in a big problem than before. Right now the demand for the high quality, low costs drugs is very more. The good news is that we have an option of the generic drugs available that are high in quality and low in price. The only need is to understand and not to believe in myths like generic drugs are or inferior quality. Generic drugs are the cheapest available option of the branded drugs in the market and show the same effects like the generic drugs. The most important thing is that generic drugs are approved by the FDA and WHO.

The financial income of the people is greatly affected because of the financial crises. All the markets are sinking because they are suffering too much lose. But, humans can not live without the medications if they have the ill health. Thus, to all these men generic drugs could be a best option to save the money. Reasons for the cheap price of the generic drug are— the cost of production of generic drug is very less as compared with the original brand name companies, no investment is done for the research on generic drug as the research is already conducted by the brand name manufacturer, clinical trials are not conducted by the generic drug manufacturer because they are previously conducted by the brand name manufacturer, and no cost is involved in the advertising and marketing of the generic drug because they get the benefit of the advertising and marketing done by the original drug manufacturer. Thus, generic drug allows the manufacturer to earn lots of profits.

Generic drugs not only save the money of the customers but also save the investment of the government in the pharmaceutical sector. US govt. has saved about 1 Billion dollars because of the generic drugs in the year 2007-08. Insurers are also very beneficial due to the use of the generic drugs. Insurance companies are asking the doctors to follow the step therapy that means doctors should first prescribe the generic drugs and if these drugs fail to produce the required effect then they should prescribe the more expensive brand-name drugs. FDA is sending pamphlets to the big pharmacy chain in US to promote the generic drugs. FDA is even asking these pharmacies to promote the sale of generic drugs. FDA says that all drugs must work well and be safe. FDA makes sure that before approving that generic drugs are of high quality, strong, pure, and stable as their respective brand-name drugs.

Generic drugs are allowed to be sold in the market only after they satisfy the following criteria:

•    Generic drug should have the same ingredient as the original drug.
•    Generic drug must be identical or bioequivalent to the original drug.
•    The pharmacokinetic and pharmacodynamic properties of the generic drugs should be similar to the original drugs.
•    Generic drugs should be similar in strength in comparison with the original brand name drug.
•    The side-effects of the generic drug are less or more than the original brand name drug.

Generic drugs are manufactured in the world class units that are checked and then approved by the FDA. The safety of the generic drugs is not at all in doubt because no casualties till date are noted by the intake of the generic drugs. Thus even the pharmacy distributors believe in the generic drug manufacturer and thus the sale of generic drug increases. Customer is using generic drugs because of the cost benefits and he is enjoying the same effects that he used to get by the original branded drugs. Hence, we can conclude that generic drugs perfectly match the demand of time.

Sports Nutrition Products – A Marketing Invention Or A Real Need?

Thursday, April 1st, 2010

In 2003, it was reported that the total retail market for sports nutrition, the value reached $ 3. 1 billion. Beverages accounted for 63 percent of sales, according to a new report from Packaged Facts. However, these drinks have been marketed more for general nutrition, rather than sporting benefits. Packaged Facts has confirmed that physically active adults were able to use only 10 percent of sports drinks rather than the general adult population. Even if you are in sport, just your regular supply of larger quantities of water. You do not need a sports nutrition product. Right? Wrong. The need for recreation and sports nutrition products Records of Antiquities show that athletics is an integral part of human life earlier. Athletic life was originally designed for survival by collecting food or self-protection. Later, it became a contest of power, speed, agility and mental sharpness. Over time, these activities in what we now know how the various forms of exercise or sports development. Our ancestors, even understand the need for our body movement and other forms of physical activity. They instinctively know that to get in terms of health and develop their physical, they must have some activities. And this early, they understand the need for a special diet, the modern version, which is our sports nutrition products. the basic feeding habits of our ancestors Evidence of prehistoric human diet, the artifacts of food preparation such as milling, cooking can be seen, and finally cooking. These bits of information, we are informed, that the basic scheme of the early Greeks and Romans, for example, was a perfect combination of plant and animals. They ate more of a variety of cereals, vegetables, fruit (fresh and dried), and lots of wine (usually diluted with water to varying degrees). Ancient Greeks, “Main Source, is that goat meat. In Italy, there was pork products, especially bacon. Beef has been eaten occasionally, especially for victims in many temples. Milk and dairy products milk, and, perhaps, is a very popular food. Fish and poultry were also part of the normal diet. The small difference in these early humans in our modern diet is that olive oil was consumed in greater quantity of butter. The oil was also a major source of domestic lighting. Combined with good sports nutrition products, this system has a formula for thousands of years, is an ideal food for a modern sports-man. Our ancestors knew then that, although abundant in natural foods, there are several sources, improved nutrition fit lifestyle. sports nutrition products Fast forward in our modern context. It is important for athletes proper nutrition for maximum stability, optimal mobility, have stamina and improves overall performance. The foundation for a successful athletic program remember a good combination of a well thought-based Whole Foods (vegetables, fruits, whole grains and protein, the Greeks?) Supplemented by a special sports nutrition products and of course a good exercise therapy. It is true that commitment, and good training methods, and genetics are still the most important to the effectiveness of an athlete, the lack of an appropriate scheme in the absence of dietary supplements such as sports nutrition products related to the performance of athletes in all other forms of preventing the exercise. Without a good diet with sports nutrition products, pre-games and contests right combination can end disastrously. optimal nutrition can be achieved only by practice perfect food, combined with sports nutrition products as an important element. Only through sustained compliance with the right combination of diet and sports nutrition products that excellent performance is guaranteed. But it’s a start. It would be a while until we realized that a good body and healthy as possible, not only by eating foods, but by following a particular sport, combined with healthy eating, and of course products sports nutrition. We should learn from the ancient Greeks and Romans. With experience, they learned that integration can consume a regular exercise and a balanced diet results in a long and fruitful life.
