Had EDNOS but now its anorexia. Im still healthy wt (BMI 20.6). Thyroid hormones were fine on recent blood test.Does that mean my BMR isnt slowed yet?
It is complicated to calculate true BMR, as both overweight and underweight people can have a low BMR. Activity, body muscle/fat proportion, insulin and other hormonal factors all contribute and thyroid hormone is only one factor. When the body senses starvation, especially with a low BMI, basal metabolic rate will slow down to conserve calories, so keeping weight in the normal range is helpful.
