How to Count Calories to Lose Weight (Calorie Calculator for Weight Loss)

Calories and weight loss -

Keep reading to learn more about how to calculate your calorie deficit and how to reach it healthily. For most people, a calorie deficit of — is sufficient to lose 0. However, this needs to be re-evaluated constantly, especially as you lose weight. To calculate your calorie deficit, you will first need to calculate your maintenance calories.

These are the number of calories your body needs to support energy expenditure. You can use a calorie calculator, like the Body Weight Planner from the National Institutes of Health NIH.

It estimates your maintenance calories based on your weight, sex, age, height, and physical activity level. Your BMR is the minimum amount of calories your body needs to perform basic functions, such as breathing.

Combining your BMR and activity levels can help you estimate your maintenance calories. Below are two formulas to estimate your BMR, based on sex assigned at birth:. Once you have your BMR, you can then calculate your maintenance calories using the Harris-Benedict Formula :.

For a more precise number, track your calorie intake and weight for 10 days while maintaining the same level of daily activity. You can use a calorie tracking app to track your calories and weigh yourself daily.

For an accurate result:. Divide the total number of calories you consumed for 10 days by 10 to find your average daily calorie intake.

Then, subtract calories from this number to determine your new daily intake goal for weight loss. For example, if you find your maintenance calories to be 2, per day, your new daily calorie goal would be 1, As you lose weight, your maintenance calories will decrease over time.

It may change and slow down to meet your new calorie intake. This can make weight loss more difficult in the end. You can reach a calorie deficit by consuming fewer calories or increasing your physical activity levels — or both.

Creating a calorie deficit alongside being physically active may be a more sustainable, safe, and effective weight loss method. The Dietary Guidelines for Americans — suggest that a healthy dietary pattern is key for supporting your calorie needs and reducing your risk of some health conditions, such as cardiovascular disease and type 2 diabetes.

A well-balanced, nutritious diet may include:. Here are some tips that may also help you lower your caloric intake without having to count calories:. Weight loss is just one of the many benefits of getting regular physical activity.

The Physical Activity Guidelines for Americans recommend that adults do — minutes of moderate intensity exercise, or 75— minutes of vigorous intensity exercise, weekly.

Moderate intensity exercise may include brisk walking , light bicycling , and yoga , while vigorous intensity exercise may include jogging and fast bicycling. The guidelines also recommend that adults do muscle-strengthening activities involving their major muscle groups — including the back, shoulders, chest, arms, and legs — at least two days every week.

The Harris-Benedict Equation was one of the earliest equations used to calculate basal metabolic rate BMR , which is the amount of energy expended per day at rest. It was revised in to be more accurate and was used up until , when the Mifflin-St Jeor Equation was introduced.

The Mifflin-St Jeor Equation also calculates BMR, and has been shown to be more accurate than the revised Harris-Benedict Equation. The Katch-McArdle Formula is slightly different in that it calculates resting daily energy expenditure RDEE , which takes lean body mass into account, something that neither the Mifflin-St Jeor nor the Harris-Benedict Equation do.

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:. where: W is body weight in kg H is body height in cm A is age F is body fat in percentage. 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 manner 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 the 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. 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 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.

Try these 10 ways to cut calories every day. It is easier than you may think. Swap your snack. Many people reach for a snack or two in between meals. Snacking is fine as long as you choose options that will fill up with fewer calories.

The key is to have some healthy snacks ready when hunger hits. Instead of a 3-ounce 85 g bag of flavored tortilla chips calories , choose a cup mg of air-popped popcorn 31 calories , a cup mg of grapes and a low-fat cheese stick or a small apple and 12 almonds calories.

Choosing healthy snacks twice a day will easily save you calories. Cut one high-calorie treat. Try to remove one high-calorie food item each day. Whether it is a donut in the morning, a brownie or bag of chips at lunch, or chocolate cake after dinner, you will save to calories or more.

To burn another calories, take a minute brisk walk after lunch or dinner. Do not drink your calories. One ounce mL regular soda has about calories, and a ounce mL flavored latte can pack calories or more.

Even fruit smoothies have lots of calories, as many as in a ounce mL serving. A couple of sweet drinks a day can easily add up to calories or more. Choose water, plain or flavored, sparkling water, or black coffee or tea instead and save your calories for foods that will help you feel full.

Skip seconds. Taking a second helping can add up to unwanted calories. It is easy to keep filling your plate when you serve food family style on the table. Instead, fill your plate once and keep extras in the kitchen. Or, if you still do not feel satisfied, add a second helping of vegetables, fruit, or salad.

Make low calorie substitutions. Substitute lower-calorie options for some of your high-calorie favorites. For example, if a recipe calls for a cup mL of sour cream calories , use plain low-fat yogurt or Greek yogurt instead calories.

Ask for a doggie bag.
