How to Calculate a Calorie Deficit<\/figcaption><\/figure>\nTo calculate a calorie deficit, you need to determine your calorie intake (BMR) and the calories burned in a day (TDEE) using the following formulas:<\/p>\n
Step 1: Calculate BMR (Basal Metabolic Rate)\u00a0<\/strong><\/p>\nBMR is the number of calories needed to maintain basic life-sustaining activities such as breathing, maintaining blood pressure, and digestion. Here, we use the Mifflin-St Jeor Equation:<\/p>\n
\nMen:<\/strong> BMR = 10W + 6.25H \u2013 5A + 5<\/li>\nWomen:<\/strong> BMR = 10W + 6.25H \u2013 5A \u2013 161<\/li>\n<\/ul>\nNote:<\/p>\n
\nW<\/strong> is body weight in kg<\/li>\nH<\/strong> is height in cm<\/li>\nA<\/strong> is age<\/li>\n<\/ul>\nStep 2: Calculate TDEE (Total Daily Energy Expenditure)<\/strong><\/p>\nTDEE is the total number of calories you burn in a day, based on the formula:<\/p>\n
\nTDEE = BMR x Activity Factor<\/li>\n<\/ul>\nActivity Factors:<\/p>\n
\nTDEE = BMR x 1.2 if you are sedentary or do not exercise<\/li>\n TDEE = BMR x 1.375 if you exercise lightly 1-3 days\/week<\/li>\n TDEE = BMR x 1.55 if you exercise moderately 3-5 days\/week<\/li>\n TDEE = BMR x 1.725 if you engage in heavy exercise 6-7 days\/week<\/li>\n TDEE = BMR x 1.9 if you exercise intensely twice a day<\/li>\n<\/ul>\nYou can calculate BMR and TDEE by entering your information on online calculators or tools available on websites like HelloBacsi.<\/p>\n
Step 3: Calculate the Calorie Deficit\u00a0<\/strong><\/p>\nCalorie Deficit = TDEE – BMR<\/p>\n
According to the American Heart Association, you can lose 0.45 kg (1 lb) in a week if you eat 500 calories less than your daily maintenance calories.<\/p>\n
For example: If your TDEE (calories burned) is 2,000 calories a day and your intake is 1,500 calories (a calorie deficit of 2,000 – 1,500 = 500 calories); consistently maintaining these figures for 7 days, you will lose 0.45 kg (1 lb).<\/p>\n
You can lose weight faster by increasing the intensity and duration of your workouts to burn more calories.<\/p>\n
3. Safe Calorie Deficit Levels Recommended by Experts\u00a0<\/strong><\/h2>\nExperts recommend starting with a calorie deficit of 200-300 calories and gradually increasing to 500-750 calories to allow the body to adapt gradually.<\/p>\nSafe Calorie Deficit Levels Recommended<\/figcaption><\/figure>\nAdditionally, it’s essential to ensure adequate calorie intake for energy and safe weight loss:<\/p>\n
\nWomen should aim for 1,200 to 1,500 calories per day for safe weight loss.<\/li>\n Men should aim for 1,500 to 1,800 calories per day for safe weight loss.<\/li>\n Overweight or obese adults should reduce total calorie intake by adopting various eating styles over 6 months to 2 years.<\/li>\n<\/ul>\n4. Who Should Not Follow a Calorie Deficit Diet\u00a0<\/strong><\/h2>\nWhile the benefits of a calorie deficit in weight loss are undeniable, some individuals with certain health conditions should not follow this diet without consulting a specialist:<\/p>\n
\nPeople with type 2 diabetes<\/strong>: A lack of calories can lead to dangerously low blood sugar levels.<\/li>\nKidney problems:<\/strong> Changes in water intake during calorie reduction can strain the kidneys.<\/li>\nHigh or low blood pressure:<\/strong> Hydration changes and reduced water intake can affect blood pressure.<\/li>\n<\/ul>\nIndividuals with these health issues should consult with medical professionals before adopting a calorie deficit diet.<\/p>\nWho Should Not Follow a Calorie Deficit Diet<\/figcaption><\/figure>\n5.
