Summary
Resting metabolic rate (RMR) in women with anorexia nervosa increased during refeeding, but standard formulas and fat-free mass (FFM) are unreliable for predicting caloric needs. Body dissatisfaction requires further attention in treatment.
Area of Science:
- Metabolism and Nutrition
- Psychiatry and Psychology
- Eating Disorders
Background:
- Anorexia nervosa (AN) is a severe psychiatric disorder characterized by distorted body image and restricted eating.
- Refeeding is a critical phase in AN treatment, requiring careful management of metabolic and psychological adjustments.
Purpose of the Study:
- To investigate resting metabolic rate (RMR) and psychological changes during refeeding in women with AN.
- To assess the accuracy of standard predictive equations and fat-free mass (FFM) for caloric needs during refeeding.
Main Methods:
- 10 women with AN in a partial hospitalization program were studied.
- RMR was measured using the MedGem Analyzer.
- Psychological status was assessed using validated questionnaires (EAT-26, EDI-2, BSI, Mizes Anorectic Cognitions).
Main Results:
- Admission RMRs were lower than predicted by the Harris-Benedict equation.
- RMR per pound of FFM increased significantly throughout treatment.
- Psychological measures, including depression and eating disorder cognitions, improved significantly, but body dissatisfaction did not.
Conclusions:
- Standard formulas and FFM are insufficient for predicting caloric needs during AN refeeding.
- Admission BMI is a relevant factor for estimating caloric requirements.
- Improving body dissatisfaction should be a greater focus in AN refeeding programs.

01:28Anorexia Nervosa
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

01:30Bulimia Nervosa
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
01:23Binge Eating Disorders
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
01:24Metabolic States of the Body: Fasting and Starvation
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
01:18Metabolic States of the Body: The Postabsorptive State
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

01:30Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
