Nutritionist use an overweight person’s BMI to calculate the number of calories to cut from the diet. People with a BMI of 35 or greater are encouraged to reduce their daily calories by about 500 to 1,000 calories from their usual intakes. People with a BMI between 27 and 35 should reduce energy intake by 300 to 500 calories a day. This is calculated under the assumption that a 3,500-calorie deficit will consistently produce a pound of weight loss, such recommendations predict weight loss of 1 to 2 pounds per week while retaining lean tissue.

Furthermore, recent research suggests that the number of calories required to lose a pound of weight may increase as weight loss progresses. For some weeks or months, weight loss may proceed rapidly. Eventually, these factors may contribute to a slowdown in the rate of loss. This is because, metabolism may slow in response to a lower calorie intake and loss of metabolically active lean tissue, and less energy may be expended in physical activity as body weight diminishes.

In addition, the composition of weight loss itself may affect the rate of loss. Body weight lost early in dieting may be composed of a greater percentage of water and lean tissue, which contains fewer calories per pound, as compared with later losses that appear to be composed mostly of fat, which contains far more calories per pound. Therefore, dieters should expect a slowdown in weight loss as they progress past the initial phase.
