What Is a Calorie Deficit?
A calorie deficit is when you burn more calories than you eat in a day, which can help you lose system of weights, according to the Centers for Disease Control and Prevention ( CDC ). You can create a calorie deficit by eating fewer calories in your diet, exercising more or a combination of both .

What Calorie Deficit Is Needed for Weight Loss?
precisely how many calories you should eat per day to maintain your weight unit varies based on your historic period, arouse and natural process levels. But in general, the 2020-2025 Dietary Guidelines for Americans recommends people assigned female at parentage ( AFAB ) eat 1,600 to 2,000 calories and people assigned male at birth ( AMAB ) eat 2,000 to 2,400 calories per day to maintain weight .
ad To lose weight unit at the safe and sustainable CDC -recommended pace of 1 to 2 pounds per week, the Mayo Clinic suggests cutting approximately 500 to 1,000 calories from that daily service line. Why ? You lose 1 pound when you burn about 3,500 more calories than you eat. hera ‘s how many calories to cut for your weight-loss goals :

- To lose 1 pound per week: Maintenance calories – 500 = Daily calorie goal
- To lose 2 pounds per week: Maintenance calories – 1,000 = Daily calorie goal
Warning
Your calorie intake should n’t dip below 1,200 per day if you ‘re AFAB or 1,500 per sidereal day if you ‘re AMAB unless under doctor ‘s orders, per Harvard Health Publishing. Anything less than that may deprive you of nutrients .
How to Calculate Your Calorie Deficit
There are a few ways you can calculate your calorie deficit for weight loss .
1. Use a Calorie-Tracking App
A diet- and fitness-tracking app like LIVESTRONG.com ‘s MyPlate is like a calorie deficit calculator in your pocket. here ‘s how to get started :
- Download the app onto your phone or other device.
- Fill out your height, weight, goal weight and activity level for an automatic daily caloric intake recommendation.
- Track your calorie intake by adding your foods and beverages (you can search MyPlate’s catalogue or scan the food or drink’s barcode).
- Track your calorie burn by entering your exercise sessions (you can search by activity or manually enter the amount of calories you burned).
2. Calculate Calorie Deficit Manually
You can besides manually calculate your daily thermal intake for weight loss. To do so, you first need to determine your basal metabolic rate ( BMR ) or resting metabolic rate ( RMR ), which are measures of how many calories your body needs at lie, per the american Council on Exercise ( ACE ) .
While BMR and RMR are alike, BMR is typically used in more controlled settings like a doctor ‘s function, whereas RMR may better represent how many calories your body needs at respite in everyday life, per ACE .
1. Find Your BMR or RMR
Calculate your BMR using the Mifflin-St. Jeor equation or Katch-McArdle equality :
- Mifflin-St. Jeor equation for people AFAB: (9.99 x weight in kg) + (6.25 x height in cm) – (4.92 x age) – 161
- Mifflin-St. Jeor equation for people AMAB: (9.99 x weight in kg) + (6.25 x height in cm) – (4.92 x age) + 5
- Katch-McArdle equation: 370 + (21.6 x lean body mass in kg). Lean body mass = total body weight in kg – weight from body fat in kg.
Calculate your RMR with the following equation :
- Cunningham Equation: 500 + (22 x lean body mass in kg)
2. Use Your BMR to Find Your TDEE
once you know your BMR or RMR, you can then factor in physical action to calculate your total daily energy expending ( TDEE ), which is the sum total of calories you burn every day, per ACE. Just multiply your BMR or RMR by the number below that best corresponds to your bodily process flat :
- Sedentary: 1.2
- Lightly active (exercise 1 to 3 times per week): 1.375
- Moderately active (exercise 3 to 5 times per week): 1.55
- Very active (hard exercise 6 to 7 times per week): 1.725
- Extremely active (hard daily exercise and a physical job): 1.9
3. Subtract Weight-Loss Calories
From there, subtract your day by day calorie deficit finish of 500 to 1,000 to calculate how many calories you should eat per day for weight passing.

Katch-McArdle equation | 370 + ( 21.6 ten 63.5 ) | 1,741.6 x 1.55 | 2,699.48 – 1,000 | 1,699.48 |

How to Achieve Your Calorie Deficit
now that you know how to calculate a calorie deficit, here are some tips to actually create that deficit to lose weight unit .
1. Eat Fewer Calories
Cutting back on your day by day food consumption can create a calorie deficit, per the Mayo Clinic. This does n’t necessarily mean drastically reducing how much you eat, though : In general, prioritizing alimentary whole foods like fruits, vegetables and solid grains over refined foods like packaged baked goods will help you naturally eat fewer calories .
The Mayo Clinic besides recommends trying these strategies :
- Reduce your portion sizes
- Limit or avoid high-calorie, low-nutrition foods like candy or soda
- Replace high-calorie snacks with lower-calorie substitutes, like crispy chickpeas instead of chips
2. Exercise More
You can besides supplement a deficit by burning calories through regular physical bodily process. The CDC recommends adults get at least 150 minutes of exert ( including cardio activities and lastingness coach ) each week .
If you ‘d like to keep chase of how many calories you burn during your exercise rather than trust on the bodily process multipliers listed above, cardio machines and calorie-tracking apps can normally estimate it for you. But if you ‘d like to do it yourself, there ‘s a formula to help .
Before crunching the numbers, depart by determining your affection rate with the help of a heart rate monitor or by placing your fingers on the side of your throat and counting how many times your heart beats in a minute. then use the watch equations :
- AFAB: [(-20.4022 + (0.4472 x heart rate in beats per minute) + (0.278 x weight in lbs) + (0.074 x age in years)] / 4.184. Then multiply your result by the number of minutes exercised
- AMAB: [(-55.0969 + (0.6309 x heart rate in beats per minute) + (0.438 x weight in lbs) + (0.2017 x age in years)] / 4.184. Then multiply your result by the number of minutes exercised
How to Determine How many Calories to Eat With exercise preferably than using the activity multiplier, you can factor the accurate number of calories you burned during exert into your daily thermal allowance with the postdate calculation :
- BMR + calories burned during exercise – calorie deficit goal = daily calorie allowance
For model, a person with a BMR of 2,000 calories a day who burns 300 calories from exert with a weight loss goal of 1 syrian pound per week has a daily caloric allowance of 1,800 calories ( 2,000 + 300 – 500 = 1,800 ) .
