Oct 16,  · The average, moderately active woman between the ages of 26–50 needs to eat about 2, calories per day to maintain her weight and 1, calories per day to lose 1 pound Estimated Reading Time: 6 mins. To lose weight -- It used to be recommended that to lose a pound per week you would need to decrease total calories by a day. Now researchers believe weight loss is a slower process and that a.

The Calorie Calculator can be used to estimate the number of calories a person needs to consume each day. This calculator can also provide some simple what is the daily calorie intake to lose weight for gaining or losing weight.

The following converter can be used to convert between Calories and other common food energy units. This Calorie Calculator is based on several equations, and the results of the calculator are based on an estimated average. The Harris-Benedict Equation was one of the earliest equations used to calculate basal metabolic rate BMRwhich is the amount of energy expended per day at rest. It was revised in to be more accurate and was used up untilwhen the Mifflin-St Jeor Equation was introduced.

Of these equations, 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 and know their body fat percentage.

The three equations used by the calculator are listed below:. The value obtained from these equations is the estimated number of calories a person can consume in a day to maintain their body-weight, assuming they remain at rest. This value is multiplied by an activity factor generally 1. As such, in order to lose 1 pound per week, it is recommended that calories be shaved off the estimate of calories necessary for weight maintenance per day. For example, if a person has an estimated allotment of 2, calories per day to maintain body-weight, consuming 2, calories per day for one week would theoretically result in 3, calories or 1 pound lost during the period.

It is important to remember that proper diet and exercise is largely accepted as the best way to lose weight.

It is inadvisable to lower calorie intake by more than 1, calories per day, as losing more than 2 pounds per week can be unhealthy, and can result in the opposite effect in the near future by reducing metabolism. Losing more than 2 pounds a week will likely involve muscle loss, which in turn lowers BMR, since more muscle mass results in higher BMR.

Excessive weight loss can also be due to dehydration, which is unhealthy. Furthermore, particularly when exercising in conjunction with dieting, maintaining a good diet is important, since the body needs to be able to support its metabolic processes and replenish itself.

Depriving the body of the nutrients it requires as part of heavily unhealthy diets can have serious detrimental effects, and weight lost in this how to add refrigerant oil to car has been shown in some studies to be unsustainable, since the weight is often regained in the form of fat putting the participant in a worse state than when beginning the diet.

As such, in addition to monitoring calorie intake, it is important to maintain levels of fiber intake as well as other nutritional necessities to balance the needs of the body. Calorie counting with the intent of losing weight, on its simplest levels, can be broken down into a few general steps:. 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 how to heal burn wounds have been found to have different effects on health, feelings of how to publish with frontpage, and number of calories burned.

Generally, minimally processed plant and animal foods tend to be more conducive to healthy weight loss and maintenance. There are many approaches to weight loss and there is no set ideal method that works for all people, which is why so many different diets and exercise regimens exist.

While some methods are more effective for each individual person, not all weight loss methods are equivalent, and studies suggest that some approaches are healthier than others. That being said, one of the most commonly effective weight loss methods is counting calories.

In its most basic form, calories consumed minus calories expended will result in weight gain if the result is positive, or weight loss if the result is negative. However, this is far from a comprehensive picture, and many other factors play a role in affecting healthy, sustainable weight loss. For example, there exist conflicting studies addressing whether or not the type of calories or foods consumed, or how they are consumed, affects weight loss.

Studies have shown that foods that require a person to chew more and are more difficult to digest result in the body burning more calories, sometimes referred to as the thermic effect of food. While the increase in burned calories may be marginal, foods that are more difficult to digest such as vegetables generally tend to be healthier and provide more nutrients for fewer calories than many processed foods.

Consistent with the view that in regards to weight loss, only net calories are important and not their source, there exist cases such as the Twinkie diet, where a person that solely counted calories while eating a variety of cake snacks managed to lose 27 pounds over two months. As effective as this can be, it is certainly not suggested. While the participant did not seem to suffer any noticeable health detriments in this particular case, there are other less measurable factors that should be considered such as long-term effects of such a diet on potential for developing cancers, heart disease, and diabetes.

However, ignoring efficiency and health, sustained, significant reduction of caloric intake or increase of physical activity should result in weight loss, and counting calories can be an effective way to achieve this sole result. Aside from being one viable method for facilitating weight loss, calorie counting has other somewhat less quantifiable advantages including helping to increase nutritional awareness.

Many people are completely unaware of, or grossly underestimate their daily caloric intake. Counting calories can help raise an awareness of different types of foods, the number of calories they contain, and how these calories have a different effect on a person's feelings of satiety.

Once a person has a better understanding of how many calories are actually in that bag of chips that they can so easily inhale within minutes, how much of their daily caloric intake it consumes, and how little the chips do to satiate their hunger, portion control and avoidance of foods with empty calories tends to become easier.

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 how to delete google account 2012 to fill their plates and eat everything on their plates.

Many people do not realize that they are overeating, since what love will make you do have become accustomed to restaurant-sized what to wear in thailand in february being the norm, when said portions can be up to three or more times larger than necessary for a typical meal.

Once a link is made between the amount of exercise that some snack equates to, many people find abstaining from that bag of chips to be the preferred option rather than performing an equivalent amount of exercise — which can lead to healthier eating habits. 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. Zigzag calorie cycling is a weight loss approach that aims to counteract the human body's natural adaptive tendencies.

Counting and restricting calories, as described above, is a viable method to lose weight, but over a period of time, it is possible for the body to adapt to the lower number of calories consumed. In cases where this happens, a how to get url from youtube in weight loss that can be difficult to surmount can result.

This is where zigzag calorie cycling can help, by not allowing the body to adapt to the lower calorie environment. Zigzag calorie cycling involves alternating the number of calories consumed on a given day. A person on a zigzag diet should have a combination of high-calorie and low-calorie days to meet the same overall weekly calorie target.

For example, if your target calorie intake is 14, calories per week, you could consume 2, calories three days a week, and 1, the other four days of the week, or you could consume 2, calories each day. In both cases, 14, calories would be consumed over the week, how to upload software to blog the body wouldn't adapt and compensate for a 2,calorie diet.

This also what is the daily calorie intake to lose weight a person more flexibility in their diet, allowing them to plan around occasions, such as work or family gatherings, where a person may consume more calories. Consuming a lower number of calories on other days can allow a person to enjoy these gatherings or even have a "cheat day" where they eat whatever they want without feeling guilty, since they can make up for the excess calories on their low-calorie days.

There is no concrete rule or study that dictates the most effective way to alternate or spread out calorie consumption. How to vary calorie intake is largely up to personal discretion.

Depending on a person's activity, it is generally recommended that the high-calorie and low-calorie days vary by approximately calories, where the high-calorie day is often the number of calories a person needs to consume to maintain their current weight. For a person with a higher activity level, the calorie difference should be larger.

The calculator presents two zigzag diet schedules. The first schedule has two higher calorie days, and 5 lower calorie days. The second schedule increase and reduces calories gradually. In either case, the total weekly calorie consumption is the same. In the end, regardless what method you choose to use when approaching weight loss, what's important is picking a strategy that works for you.

Calorie counting and zigzag calorie cycling are only two methods that are fairly interrelated used to achieve weight loss among many, and even within these methods, 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 and desirable result. 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 — there are many different factors involved, not all of which are well-understood or known. 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 year-old male that is 6 feet in height requires considerably higher calorie intake than a 5-foot-tall, sedentary year-old woman. Though it differs depending on age and activity level, adult males generally require 2, calories per day to maintain weight while adult females need around 1, according to the U.

S Department of Health. 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.

Harvard Health Publications suggests women get at least 1, calories and men get at least 1, calories a day how to apply for a va home improvement loan supervised by doctors. 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.

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.

Generally, foods that take more effort to chew — fruit, vegetables, lean meats, whole grains, etc. 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.

The "quality" of calories consumed is also important. There are different classifications of foods in terms of calories. This includes high-calorie foods, low-calorie foods, and empty calories.

Consistent with their naming, high-calorie foods are foods that are calorically dense, meaning that there are a high number of calories relative to serving size, while low-calorie foods have fewer calories relative to serving size.

Foods such as fat, oils, fried foods, and sugary foods are examples of high-calorie foods. Being a high-calorie food does not inherently mean that the food is unhealthy however how to make stuffed toys avocados, quinoa, nuts, and whole grains are all high-calorie foods that are considered healthful in moderation.

Low calorie foods include vegetables and certain fruits, among other things, while empty calories, such as those in added sugars and solid fats, are calories that contain few to no nutrients. Studies have shown that there is a measurable difference between consuming calories of carrots compared to calories of popcorn. As previously mentioned, this in part can be attributed to differences in how the foods are consumed and processed.

Carrots require far more chewing and can result in more calories burned during digestion.

Energy Requirements

For 2 pounds weight loss per week: In addition to the one pound rule, in-clude physical exercise for 45 minutes to 1 hour daily. For healthy living and weight maintenance: Keep your calorie intake the same daily. Focus on whole unprocessed foods, whole grains, good . For people with only a small amount of weight to lose, calories will be too much of a deficit. As a guide to minimum calorie intake, the American College of Sports Medicine (ACSM) recommends that calorie levels never drop below calories per day for women or calories per day for men. Even these calorie levels are quite low. Sep 11,  · Calories a Day Losing a pound requires burning an extra 3, calories. Since there are 7 days in a week, this would mean losing a pound a week would require a calorie daily deficit. How long would I have to ___ to burn calories?

Calorie Needs to lose weight There are approximately calories in a pound of stored body fat. So, if you create a calorie deficit through diet, exercise or a combination of both, you will lose one pound of body weight.

The calorie deficit can be achieved either by calorie-restriction alone, or by a combination of fewer calories in diet and more calories out exercise. This combination of diet and exercise is best for lasting weight loss. Indeed, sustained weight loss is difficult or impossible without increased regular exercise. If you want to lose fat, a useful guideline for lowering your calorie intake is to reduce your calories by at least , but not more than below your maintenance level.

For people with only a small amount of weight to lose, calories will be too much of a deficit. As a guide to minimum calorie intake, the American College of Sports Medicine ACSM recommends that calorie levels never drop below calories per day for women or calories per day for men.

Even these calorie levels are quite low. An alternative way of calculating a safe minimum calorie-intake level is by reference to your body weight or current body weight. You may increase this depending on your weight loss goals.
