Want to lose weight? Then there's no way around a little math. Here's how to subtract calories from your diet, adding up to gradual weight loss that lasts. Weight loss is a numbers game. The rule used to be that to lose 1 pound lb of fat, you needed to burn 3, fewer calories than you ate.
Studies show that 3, calories largely overestimates how much weight someone will lose as well as how much of that weight will be from fat. Researchers explain that much of the discrepancy is because the way the body expends energy called metabolism changes with weight fluctuations. Plus, as Dr. Foster notes, all of the weight lost comes from a combination of fat and lean tissue, which is mostly muscle. While multiple diet and exercise variables determine how much comes from fat versus muscle, caloric deficits never target fat exclusively.
To lose a pound, you need to have a good idea of how many calories you burn use for energy on an average day. According to the U. Department of Health and Human Services , the average adult woman expends roughly 1, to 2, calories per day, and the average adult man uses 2, to 3, calories per day.
The average adult woman is 5 feet 4 inches tall and weighs lbs, while the average man is 5 feet 10 inches tall and weighs lbs. Yet age, activity level, body size, and body composition all influence how many calories a person burns through each day.
To get a more accurate idea of your daily caloric requirements, you can turn to an online metabolic rate calculator. These determine basal metabolic rate BMR , which refers to the number of calories that the body burns every day for energy just to maintain basic biological functions.
When multiplied by an activity factor how much you move in a day , you get your daily metabolic rate, 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 , a registered dietitian nutritionist at LBS Nutrition in East Brunswick, New Jersey, and the author of Cooking Well Healthy Kids.
The not-so-simple part is that everyone burns a different amount of calories at rest, which you need to consider before figuring out how many calories you burn during a workout and then how many calories to eat.
This is why consulting with a dietitian or nutritionist can come in handy, since they are trained to help address your body's specific calorie needs. But without one, you can still estimate many calories you need each day and how much to burn when exercising.
It's important to keep a healthy mindset through this process. Exercising with the sole goal of "punishing" yourself for what you ate or to burn a ton of calories may motivate you temporarily, but the most sustainable motivation for exercise comes from something positive, like exercising to relieve stress or to have fun. Remember that exercise offers so many more benefits for your health and well-being than just weight loss or calorie burn.
With this in mind, keep reading below for guidance from a certified trainer, Brooke Taylor , on the best strategy for working out to reach your weight loss goals. 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 multiply your BMR by 7 and calorie intake by 7 you can adjust your calorie intake and workouts so that you're burning about 2, calories a week, which is the goal that Taylor gives most clients.
Calorie counts for exercise and activity will vary from person to person. Age, sex, body type, and size influence how many calories an individual will burn doing a physical activity.
In general, more intense or strenuous activity will burn more calories than lighter effort exercise. The following calorie counts are based on a pound person doing the following exercise or activity for 30 minutes:.
Anyone that wants to figure out how many calories they burn can input their statistics into a calorie calculator and find personalized results. Losing weight can be very tough to do.
