That's what RDs have been and continue to be taught, and it's promulgated by the US Surgeon General and the Academy of Nutrition and Dietetics, and it's repeated in several nutrition textbooks. Over the course of one year, that would equal 52 lbs. Cut 500 calories per day and that's 1 lb per week. It's also a method for RDs to predict in advance who's most likely to succeed at losing those excess pounds longterm.Īsk any dietitian and he or she likely will say that cutting food intake by 3,500 calories results in a 1-lb loss. The hope is that using it will result in more realistic expectations for weight loss with fewer disappointments along the way, and help explain when and why weight-loss plateaus occur, even among seemingly dedicated dieters.Īlso in development is a personalized dynamic feedback control mechanism that clients can wear to monitor their progress and determine when it's time for reassessment with a dietitian. In an effort to better understand the weight-loss process, researchers have devised an ingenious way to more accurately predict the trajectory of weight loss for individuals via a mathematical formula. However, researchers say it's not that simple. We all know the weight-loss rules: eat more calories than you burn and you'll gain weight eat fewer calories than you burn and you'll lose weight. And, unfortunately, a large percentage of those who succeed at losing weight will gain it back over time. If you've counseled clients and patients for weight loss, you know that even the most diligent of dieters eventually will reach a weight-loss steady state, a plateau, a stumbling block that can be frustrating for them and dietitians alike. Researchers have developed new mathematical formulas RDs can use to more accurately predict the rate of weight loss in patients.
