How To Calculate A Calorie Deficit For Weight Loss | Nutritionist Explains | Myprotein

We used the calculator’s daily calorie intake result to chart the number of calories one would need to cut to lose the same amount of weight. The results are presented in number of calories to lose one pound per week. The calculations are specifically for an average 5 feet 8 inches tall 30-year old male, assuming he wants to lose 10 lbs over 8 weeks without changing his current exercise routine equivalent to “light exercise”. The weight range in the graph is from 130 lbs to 300 lbs . The data below are just a case study and not a general recommendation.

You can clearly see why the 3,500 calories per week “rule” is not a good guide, at least in this particular instance since it applies only to a very narrow range of all possible cases – the graph is for a mildly obese person with the specified measurements. The range in this scenario spans from 1951 kCal to 4617 kCal to lose 1 lbs over 1 week: that’s 45% less calories to 32% more calories versus the “3,500 rule” in terms of reducing caloric input with the goal of reduction of body weight.

Using a tool like the above calorie reduction calculator allows you to get a much more precise estimate of how many calories you need to eat in order to lose weight.

How To Safely Lose Weight Using A Calorie Deficit

Although research shows the 500-calorie deficit rule may not be foolproof, it’s still the recommended guideline for losing weight among public health organizations such as the NIH, Academy of Nutrition and Dietetics, and the Mayo Clinic. And in order to lose weight with a calorie deficit, you need to maintain it over a longer period of time, says Joan Salge Blake, Ed.D., R.D.N., nutrition professor at Boston University and host of the nutrition and wellness podcast Spot On!. You can create and maintain a calorie deficit by:

  • Consuming fewer calories.
  • Increasing your daily physical activity without increasing your calorie intake.
  • A combination of both.
  • The truth is that both cutting back on calories in combination with being more active is typically the most successful way for folks to lose weight, says Salge Blake.

    A safe rate of weight loss is 1 to 2 pounds per week, according to the NIH. Anything quicker than that can potentially be dangerous and have health consequences quick weight loss increases demands on the body and can increase the risk of gall stones, malnutrition, electrolyte imbalance, and liver damage. If the rate of weight loss is quicker than 1 to 2 pounds per week , then it should be under the supervision of medical professionals.

    How Many Calories Should You Burn To Lose Weight

    If your goal is to lose weight and you’re tracking calories, then you have to burn more calories than you consume, creating a deficit. To do this, you should take into account your basal metabolic rate, which is the number of calories your body burns at rest. Then factor in how many calories you’re eating per day.

    Once you have the total calories you burn at rest and eat in a week you can adjust your calorie intake and workouts so that you’re burning about 2,000 calories a week, which is the goal that Taylor gives most clients.

    According to Taylor, aiming to lose 1-2 pounds each week is a healthy goal. One pound equals 3,500 calories, and you can split up how you create that deficit. She recommends burning 2,000 calories per week , and then trimming 1,500 calories a week from your diet, which breaks down to about 214 fewer calories per day.

    Common Mistakes When Cutting Calories

    • One of the most common mistakes is cutting too many calories at once. If you want to lose weight, you need to create a calorie deficit. But, if you cut too many calories, your body will go into starvation mode and actually hold onto weight.
    • Another common mistake is not getting enough protein when cutting calories. Protein is essential for weight loss because it helps to keep your metabolism going and helps to build muscle. Without enough protein, youll end up losing muscle mass instead of fat.
    • Another mistake people make when trying to cut calories is not eating enough healthy fats. Healthy fats are essential for weight loss as they help to keep you full and satisfied between meals.Plus, they help to boost your metabolism.
    • Finally, another common mistake people make when cutting calories is skipping meals or going too long without eating. This can actually lead to overeating later on as your body tries to make up for the lost calories. Its important to eat small, frequent meals throughout the day when trying to lose weight.

    What Is A Calorie

    In terms of the human body, a calorie is a measurement that denotes the amount of food with a specific energy-producing value. Essentially, this all means that the food and beverages you consume provide your body with energy, measured in terms of calories, to live.

    However, your body needs more than just calories to stay alive you also need nutrients including vitamins and minerals in order to keep your body functioning well.

    Increase Your Protein Intake


    To lose 100 pounds, increasing your protein intake is important.

    Diets higher in protein have been shown to boost your metabolism, curb your appetite, preserve muscle mass, and may reduce harmful belly fat (

    12 ).

    In one study, women with excess weight whose diet comprised 30% protein lost 11 pounds over 12 weeks, without restricting their calorie intake .

    Moreover, a higher protein diet may help prevent weight regain. For instance, a study found that consuming supplemental protein, which resulted in a diet comprising 18% protein compared with 15% in another study group, prevented weight regain by as much as 50% .

    Choosing healthy foods, such as meats, seafood, eggs, nuts, seeds, and legumes in favor of other foods is a great way to increase your protein intake.


    Increasing your protein intake may help you lose weight by boosting your metabolism, curbing your appetite, and reducing belly fat.

    Nutrient Deficits And Weariness May Result From Calorie Deficits

    Regularly consuming fewer calories than your body needs might make you feel fatigued and make it harder for you to get all the nutrients you need each day.

    For instance, calorie-restricted diets cannot provide enough amounts of iron, folate, or vitamin B12. It may lead to extreme fatigue and anemia.

    Cut Down On Refined Carbs

    Refined carbs undergo extensive processing, reducing the amount of fiber and micronutrients in the final product.

    These foods spike blood sugar levels, increase hunger, and are associated with increased body weight and belly fat .

    Therefore, its best to limit refined carbs like white bread, pasta, and prepackaged foods. Opt for whole-grain products like oats, brown rice, quinoa, buckwheat, and barley instead.

    How You Lose Weight

    Reducing your calorie intake along with increasing your activity level is the most effective way to lose weight. When your body is in a calorie deficit meaning you’re consuming fewer calories than you expend each day it stops storing fat and starts burning excess stores for energy. Generally speaking, 1 pound of fat is equal to 3,500 calories. Theoretically, as soon as you create a 3,500-calorie deficit, you will lose 1 pound. So if you created a daily deficit of 500 calories per day, you would lose 1 pound in the first week.

    What Is A Calorie Deficit And How Do You Calculate It For Weight Loss

    Creating a calorie deficit â where you burn more calories than you eat â can help you lose weight. And calculating your calorie deficit can help you determine how many calories to eat and burn every day to accomplish your weight-loss goals.

    A caloric deficit is created by eating less, moving more or a combination of both.

    Doing The Math With A Bmr Calculator To Make Weight Loss Work For You

    To lose a pound, you need to have a good idea of how many calories you burn on an average day. According to the U.S. Department of Health and Human Services, the average adult woman expends roughly 1,600 to 2,400 calories per day, and the average adult man uses 2,000 to 3,000 calories per day. Yet age, activity level, body size, and body composition all influence how many calories a person burns through each day.

    Once you know your current daily caloric requirement, you can create your own formula for losing weight. Simply put, as long as you are eating fewer calories than that number, or you increase your daily caloric burn with exercise, you will lose weight, explains Audra Wilson, RD, CSCS, a bariatric dietitian and strength and conditioning specialist at the Northwestern Medicine Metabolic Health and Surgical Weight Loss Center at Delnor Hospital in Geneva, Illinois.

    For example, you might eat 500 fewer calories, work off 500 more calories through exercise, or do any combination of the two actions to achieve a deficit of 500 calories. For example, you might choose to eat 250 calories fewer than your daily caloric requirement and then do a workout that burns another 250 calories, she says.

    In terms of the 3,500-calorie rule, that would mean that if you achieve that 500-calorie deficit at the end of each day, you would lose 1 lb of fat in seven days. Unfortunately, that equation tends to oversimplify and overestimate losses, so dont expect to lose that much that fast.

    Ways To Achieve A Calorie Deficit

    You can achieve a calorie deficit by consuming fewer calories or increasing your physical activity levels or both.

    That said, it may be easier and more sustainable to create a calorie deficit through diet rather than exercise alone, as you may not have the time, energy, or motivation to exercise daily. Plus, exercise doesnt burn as many calories as many people believe .

    In other words, it may be easier to eat 500 fewer calories each day than to burn this number of calories through exercise. Nonetheless, its still recommended to engage in muscle-strengthening and aerobic exercises for their beneficial effects on overall health .

    The Physical Activity Guidelines for Americans from the Department of Health and Human Services recommend that adults do 150300 minutes of moderate-intensity exercise, or 75150 minutes of vigorous-intensity exercise, weekly .

    Moderate-intensity exercise includes brisk walking and light bicycling, whereas examples of vigorous-intensity exercise are 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 .

    Engaging in muscle-strengthening activities will help your body prioritize the loss of body fat rather than muscle mass .

    Top 23 Weight Loss Tips For Women

    Diet and exercise may be key components of weight loss for women, but many other factors play a role.

    In fact, studies show that everything from sleep quality to stress levels can have a major impact on hunger, metabolism, body weight, and belly fat.

    Fortunately, making a few small changes in your daily routine can bring big benefits when it comes to weight loss.

    Here are the top 23 weight loss tips for women.

    These Three Changes Have Made My Weight

    Daily and Weekly Calorie Deficit Goal Planning For Weight Loss
  • I practiced mindful eating. Learning to eat to fulfill my hunger vs. eating to fulfill my emotions has allowed me to be intentional about reasonable portion sizes and to relearn my fullness cues. I no longer eat out of boredom or sadness, and I can comfortably leave food on my plate once I’m full.
  • I incorporated regular movement. Going from a very sedentary lifestyle to someone who’s regularly active has fundamentally changed my attitude, energy levels, and the shape of my body. By ensuring I move my body intentionally five to six days a week, I guarantee that my body grows stronger and my heart grows healthier.
  • I learned to have self-compassion. I accepted a long time ago that there is no perfect path to a healthy body. This empowers me to focus my energy on forgiving myself if I get off track and to rededicate myself to my wellness each and every day. Because I love myself and my body, I always aim for progress, not perfection.

    The More Weight You Lose The Slower Your Progress Will Be

    A comprehensive review of 90 studies found that the quicker you lose weight , the more your metabolic rate will drop.

    It’s also worth bearing in mind that your progress will likely slow the further you get down your fat loss journey.

    “It is important to know that your metabolism does drop from being in a calorie deficit, but it’s not inherently bad,” Syatt told Insider.

    “It’s just a normal human physiological response that as you’re losing weight, your body requires less energy in order to live. So your metabolism drops, you’re burning less, you’re using less energy.

    “That’s just normal in the same way that when you’re gaining weight, your metabolism is increasing, but you don’t want to add calories, you don’t want to eat more just to increase your metabolism because you’ll end up gaining weight.”

    Metabolic adaptation isn’t a problem to be “fixed,” it’s just what happens.

    However, you can keep your metabolism as high as possible by focusing on strength work and making sure you eat enough protein.

    “Resistance training to build and maintain muscle mass and adequate protein consumption can help offset some metabolic adaptation,” Storey-Gordon advised.

    An often-cited study compared three groups of people who were all put in a calorie deficit. One group was told to resistance train, the second to do cardio, and the third to do no exercise.

    Equally, researchsuggests that eating adequate protein can help keep your metabolism up when in a calorie deficit.

    Calorie Deficit To Lose Weight

    By maintaining a calorie deficit for the long term, you can lose weight. Now, you must be wondering how to be in a calorie deficit the answer is simple. There are only two ways to maintain a calorie deficit:

    • Eating fewer calories than what you burn and
    • Burning more calories than you eat.

    It is always recommended that you combine both of the above for healthy weight loss. To calculate how much calories you burn in different activities, check out the calories burned calculator.

    Remember that 1 pound of fat is about 3,500 calories. Hence, to lose 1 pound of fat, you need to create a calorie deficit of 3,500 calories.

    This means that to lose 1 pound per week, you should consume3500 / 7 = 500calories less than the number of calories your body needs per day.

    To lose weight without significantly affecting your energy levels, you should aim for a calorie deficit of 500 calories per day.

    How Many Calories Do You Need To Burn To Lose A Pound

    If you want to lose weight and reduce body fat, you need to use more calories than you consume, creating what’s called a calorie deficit. This is often accomplished by either reducing the calories you take in, increasing the calories you burn, or both. To lose a pound, you need to burn off the equivalent number of calories found in that pound.

    The common advice has long been that you need to burn 3,500 more calories than you eat to drop one pound. To do this in one week, then, you need to create a calorie deficit of 500 calories each day. However, research has demonstrated that losing weight is more complex than this basic calorie deficit formula suggests.

    If, for example, your maintenance calories were 2,000 per day, then 1200 is far too little. It entirely depends on your makeup.

    It would help if you used a calculator to determine this, as fixed numbers are not helpful.
