What are signs of slow metabolism?
Short answer: Common signs include unexplained weight gain or difficulty losing weight, persistent fatigue and cold intolerance, and symptoms such as dry skin, hair thinning, constipation, or slowed heart rate. These signs often reflect a lower resting metabolic rate due to factors like hypothyroidism, low muscle mass, caloric restriction, certain medications, or aging.
Explanation
Metabolism refers to the body’s rate of converting food and stored energy into useable fuel. A “slow” metabolism means resting energy expenditure is lower than expected for age, sex, and body composition. Medical causes (most commonly hypothyroidism), prolonged calorie deficit, reduced lean muscle, some medications (e.g., beta blockers, certain antidepressants), and aging can lower metabolic rate. Signs such as unexplained weight gain, fatigue, cold sensitivity, constipation, dry skin, hair loss, and irregular menstrual cycles are commonly reported. Objective assessment requires clinical evaluation and measurements like resting metabolic rate or thyroid function tests.
Tips
- See a healthcare provider for assessment and thyroid testing (TSH, free T4) if symptoms are new or severe.
- Increase protein intake and include regular resistance training to preserve or build lean muscle mass.
- Avoid excessive calorie restriction; very low-calorie diets can lower resting metabolic rate.
- Ensure adequate sleep and manage stress, as both affect hormones that influence metabolism.
- Review medications with your clinician that may impact metabolic rate and discuss alternatives if appropriate.
