A new study has found that increasing food intake can significantly boost resting metabolic rate (RMR) in patients with anorexia nervosa. According to the study, led by Dr. Lisa J. McCargar of the University of Alberta in Edmonton, Canada, RMR can increase by more than expected based on body mass gain alone.
Anorexia nervosa is defined by the restriction of nutrient intake relative to requirements, which leads to significantly low body weight. Patients with this eating disorder will have a fear of gaining weight along and a distorted body image with the inability to comprehend the seriousness of their condition.
The study, published in the Journal of Women’s Health, found that RMR increased by an average of 12% in patients with anorexia nervosa who participated in a nutritional repletion program. This is significantly higher than the 2-3% increase in RMR that would be expected based on body mass gain alone.
“Our findings suggest that increasing food intake can have a more profound effect on RMR than previously thought,” said Dr. McCargar.
“This has important implications for the treatment of anorexia nervosa, as well as for overall health and weight management.
Can Diet And Exercise Really Change Metabolism?
• Increased food intake boosts RMR in anorexia nervosa patients.
• Nutritional repletion programs show RMR increase.
• More RMR increase than expected with body mass gain.
• Dr. McCargar: Associate professor at University of Alberta.
• Study published in MedGenMed and Medscape Women’s Health eJournal.
• Increased food intake > expected RMR increase with weight gain.

Discussion:
Another notable person involved with the topic of resting metabolic rate (RMR) and its relationship to weight gain and weight loss is Dr. Barry S. McDonagh. Dr. McDonagh is a physician and nutritionist who has written extensively on the topic of RMR and its role in weight management. He has developed a program called the “RMR Diet,” which is based on the idea of increasing RMR through specific nutritional and exercise strategies.
Dr. McDonagh’s program focuses on the idea that RMR is a key factor in weight loss and weight gain, and that by increasing RMR, individuals can more easily achieve and maintain a healthy weight. He argues that traditional weight loss methods, such as calorie restriction and exercise, can actually decrease RMR, leading to a slower metabolism and a higher risk of weight gain.
In contrast, his program aims to increase RMR through the use of specific nutrients and exercises, which can help to boost metabolism and promote weight loss.
** It is important to eat healthy. Eat foods rich in vitamin, minerals and proteins. And avoid foods that contain a high amount of salt or sugar. Have a personal consultation with a healthcare professional before making significant changes to your diet.
