Hormonal imbalances can significantly impact your basal metabolic rate. Hormones such as thyroxine, produced by the thyroid gland, play a vital role in regulating your metabolism. imbalances in these hormones can affect the rate at which your body utilizes energy. Conditions like hypothyroidism, characterized by an underactive thyroid, can slow down your metabolism, resulting in a lower basal metabolic rate. Conversely, conditions like hyperthyroidism, characterized by an overactive thyroid, can accelerate your metabolism and lead to a higher basal metabolic rate.

Note: It’s important to consult with a healthcare professional if you suspect any potential hormonal imbalances that may be affecting your metabolic rate.

In addition to body composition and hormonal factors, other variables such as age, gender, genetics, and environmental factors also contribute to your basal metabolic rate. These elements influence the efficiency at which your body converts food into energy, making it unique to each individual.
