Calorie intake and health -

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. For many people, the new year feels like a clean slate: It can be a time to ditch unwanted habits, like overeating or being sedentary.

For example, general guidelines recommend consuming 5 portions of fruit and vegetables a day, while limiting the total energy intake from free sugars and fats. Counting calories is not recommended for people with a history of disordered eating, as it can make symptoms worse.

To help work out how much calories a person requires per day, they can attempt to calculate their BMR. However, it can be very difficult to measure BMR outside of clinical settings. As a result, it is unlikely that a person could accurately calculate their BMR at home.

As a simpler alternative, people can try calculating their resting metabolic rate RMR. The RMR estimates the number of calories a person burns during a period of inactivity. One useful way of estimating RMR is the Mifflin-St. Jeor equation :. People can also calculate their RMR using an online calculator, such as the one provided by the American Council on Exercise ACE , here.

Calculating how many calories to consume to help aid weight loss will vary from person to person. It is important to consider different factors such as sex, age, and activity levels.
