![]() Unfortunately, that equation tends to oversimplify - and overestimate - losses, so don’t expect to drop that much that fast. In terms of the 3,500-calorie rule, that means that if you achieve that 500-calorie deficit at the end of each day, you will lose 1 lb of fat in seven days. 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. 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.įor example, you might eat 500 fewer calories, work off 500 more calories through exercise, or do any combination of the two to achieve a deficit of 500 calories. Once you know your current daily caloric requirement, you can create your own formula for losing weight. But, while accurate, these calculators require you to have a tool like calipers (the “fat pinchers” your doctor may use) or a smart scale that estimates your body composition. Some BMR calculators allow you to enter your body fat versus lean mass, a percentage that accounts for a large amount of the variations between any two people’s basal metabolic rates. This is an estimate of how many calories you actually burn in 24 hours - and how many calories you need to eat every day just to keep your weight constant, says Sari Greaves, RDN, of LBS Nutrition in East Brunswick, New Jersey, and the author of Cooking Well Healthy Kids. When multiplied by an activity factor (how much you move in a day), you get your daily metabolic rate. ![]() It’s based on your height, weight, age, and sex, according to .uk. These determine basal metabolic rate ( BMR), which refers to the number of calories the body burns every day for energy just to maintain basic biological functions. To get a more accurate idea of your daily caloric requirements, you can turn to an online metabolic rate calculator. For American men, the average height is 5 feet 9 inches and average weight is 199.8 lb.) Ultimately, age, activity level, body size, and body composition all influence how many calories a person burns throughout each day. (The Centers for Disease Control and Prevention reports that the average height of an adult American woman is 5 feet 3.5 inches, and their average weight is 170.8 lb. According to the Dietary Guidelines for Americans 2020–2025, the average adult woman expends roughly 1,600 to 2,400 calories per day, while the average adult man expends 2,000 to 3,000. To lose a pound, you need to have a good idea of how many calories you burn - that is, use for energy - on an average day. Doing the Math With a BMR Calculator to Make Weight Loss Work for You ![]() “You can lose weight eating 1,200 calories of anything but in order to be healthy, the kinds of calories you eat matter.” Foster advises choosing more foods that are high in protein, unsaturated fats, and fiber - and fewer that contain lots of saturated fat and added sugars. It’s also important to look at the overall nutritional value of a food, rather than calories alone, especially when on a weight loss journey, says Foster. So, when a company or program claims to help with fat loss, that’s a fallacy. While multiple diet and exercise variables determine how much comes from fat versus muscle, caloric deficits never target fat exclusively. ![]() Foster notes, all of the lost weight comes from a combination of fat and lean tissue, which is mostly muscle. Researchers explain that much of the discrepancy is because the way body expends energy (called metabolism) changes with weight fluctuations. Studies show that eliminating 3,500 calories largely overestimates how much weight someone will lose, as well as how much of that weight will be from fat.
