A caloric deficit (also known as calorie deficit, in British English calorific deficit) is any shortage in the number of calories consumed relative to the number of calories needed for maintenance of current body weight (energy homeostasis). A deficit can be created by decreasing calories consumed by lower food intake, such as by swapping high ...
In general, a gradual calorie deficit of 500 to 750 calories a day is considered safe and sustainable for most people, leading to a weight loss of about one to two pounds a week. Kateryna ...
He concluded that a 3500 calorie excess or deficit for a person meeting his assumptions, would lead to the gain or loss, respectively, of one pound of body weight. He noted that if the assumptions he made are not met, a deficit of 3500 calories would not necessarily equate to a pound of weight loss. [citation needed]
There also exist formulas for estimating body fat percentage from an individual's weight and girth measurements. For example, the U.S. Navy circumference method compares abdomen or waist and hips measurements to neck measurement and height and other sites claim to estimate one's body fat percentage by a conversion from the body mass index .
Here's how to figure out how many calories to eat to lose weight using the Mifflin-St. Jeor equation, a calorie deficit calculator, or by working with an RD.
Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity.As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another.

Set point theory can be construed as implying weight regulation in a wide or tight range around the set point, in a symmetric or in an asymmetric manner (i.e. treating weight gain and loss either the same or differently), and may apply to regulation of body fat levels specifically (in a multi-compartment model) or to overall body weight.
