Caloric needs for weight loss -

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 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 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.

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 plateau 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, but the body wouldn't adapt and compensate for a 2,calorie diet. This also allows 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 five lower calorie days.

The second schedule increases and reduces calories gradually. In either case, the total weekly calorie consumption is the same. In the end, regardless of 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 unless supervised by doctors. As such, it is highly recommended that a person attempting to lose weight monitors their body's caloric necessities and adjusts them 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. There is lots of advice out there on how to cut calories.

We've found one of the clearest and widely agreed-to sources of information is from the Centers for Disease Control CDC , the official health organization of the United States.

Start with their article on Cutting Calories. Starting an exercise program is simpler, but there are still some useful guidelines. Try the CDC's Physical Activity for a Healthy Weight. While losing weight involves many variables that change from person to person, there is still a core science that can be the basis behind planning a weight loss strategy.

The widely-accepted science behind the weight loss calculator is:. When your body burns fat, 84 percent of it turns to carbon dioxide that your lungs exhale out of your body. The remaining 16 percent becomes water that you either secrete through your skin via sweat, or excrete via urine.

The water weight you lose while dieting is released in the form of glycogen. Low glucose levels in the blood during dieting can cause the release of some of your needed glucose.

This glucose is primarily stored in the liver and the muscles. Each gram of glycogen is bound to three or four grams of water and you excrete your glycogen during the initial stages of dieting, causing temporary weight loss.

Your body fat percentage is another metric you can use to determine your ideal weight. You shouldn't base your overall health on your weight alone. Calculating your body fat content can help you determine your weight because it accounts for your muscle mass.

To achieve healthy and sustainable weight loss, you should not lose more than two lbs of fat per week. Taking this into account, the average person would have to reach a caloric deficit of 1, calories per week.

You should consider your BMR when trying to decide your total caloric intake. If you lose more than 2 lbs per week, you are likely losing predominantly water weight. Your goal should be to lose lbs per week.

It is not useful for highly fit people who won't be using this calculator anyway. It is also not useful for very tall people. Use the color coding as a guideline for evaluating your body weight. Don't use it as a medical diagnosis. This is a reduction compared to your estimated nominal calorie consumption, meaning the amount of calories you consume while staying the same weight.

If you are currently gaining weight, you need to reduce your calories even further. Keeping track of how many calories you consume is not easy. WebMD has a good food calorie list. Powered by Shopify.
