Reducing your usual calorie intake by about 500 calories a day is still a recommended strategy for many people.
CALORIES TO LOSE WEIGHT SIMULATOR
The simulator uses your height, current weight, sex and goal weight to estimate how much you should eat and how much weight loss you can expect over time. Instead of basing your weight loss expectations on the 3500-calorie rule, use the National Institutes of Health’s free, online Body Weight Simulator to set more realistic goals. So you want to lose weight – now what? 1. The same decrease in calories leads to faster weight loss in men than women, and in younger adults than in older adults and individuals within these groups also differ. The other problem with the 3500 calorie rule is that it assumes that everyone responds to the same calorie cut with equal weight loss. This can be discouraging, but by setting realistic expectations, being patient and combining physical activity with eating less, you can be successful. If you continue to eat the same amount that helped you lose those first few pounds, your weight loss will naturally slow because your calorie deficit will get smaller as your weight goes down. What happens as you lose weight – even a pound or two – is that your body needs slightly fewer calories. This fits with what many people experience when they try to lose weight – losing the first couple of pounds may be easy, but sooner or later, weight loss plateaus. In addition, they found that weight loss slowed as the weeks progressed. In these studies, most participants lost much less weight than the 3500-calorie rule predicted. They looked at data from seven weight-loss studies where participants were closely monitored, often spending as long as 3 months in a research facility, 24 hours a day. Cutting 500 calories a day can lead to weight loss, but it may not be as much as that rule of thumb would predict.īack in 2013, researchers decided to test the 3500-calorie rule. You may still come across this advice, but new research has disproved this rule of thumb, known as the 3500-calorie rule. Put in practical terms, to drop a pound a week, you’d need to eat 500 calories less or burn 500 calories more per day. If you’ve ever tried to lose weight, you may have heard that a pound of fat equals 3500 calories.
