15 Things That Slow Your Metabolism

Metabolism, a crucial bodily process, converts food into energy. Many factors can slow this process, affecting health and energy levels, making calorie-burning harder.

Lack of Sleep

Good quality sleep is essential for a healthy metabolism. Insufficient sleep disrupts hormone regulation, leading to increased insulin resistance and slowed metabolism.

Skipping Meals

Skipping meals may slow your metabolism as your body enters 'starvation mode,' conserving energy due to uncertainty of when it will receive more fuel.


Hydration is crucial for an efficient metabolism. Water is vital for cellular processes in your body, and when dehydrated, these processes and your overall metabolic rate slow down.

Lack of Physical Activity

Sedentary lifestyles cause a decline in activity levels. Regular exercise increases muscle mass, boosting metabolism, and helps burn more calories, even at rest.


Aging naturally impacts metabolic rate, leading to a decrease in lean muscle mass and increased body fat. This shift in body composition reduces daily calorie burn.

Hormone Imbalance

Hormones, especially thyroid ones, critical for metabolism. Any imbalance can slow down metabolism as these regulate food conversion into energy.


Chronic stress boosts cortisol levels, leads to insulin resistance, fat accumulation, slows metabolism, causes emotional eating, and weight gain.


Certain drugs like antidepressants, steroids, or birth control can alter metabolism. Consult your healthcare provider for changes in metabolism during medication.

Underlying Health Conditions

Health conditions like hypothyroidism and PCOS can slow metabolism, leading to weight gain. Proper treatment can improve metabolism.

Low-Calorie Diets

Cutting calories is crucial for weight loss, but drastically reducing intake can slow your metabolism. Insufficient calories can trigger 'starvation mode', conserving energy.

Caffeine Intake

Caffeine boosts metabolism temporarily, but overuse may result in dependency and a reduced metabolic rate. Sugary caffeinated drinks can cause weight gain and slow metabolism.

Alcohol Consumption

Alcohol contains empty calories providing no nutritional value. Excessive consumption interrupts the body's fat-burning process, causing weight gain and slow metabolism.

Sea Salt Consumption

Sea salt, often marketed as a healthier alternative to table salt, contains less iodine, essential for thyroid function and metabolism. Iodine deficiency can slow down metabolism.


Genetics partially influence your metabolic rate. Though some may inherit a slower metabolism, healthy lifestyle changes can improve your metabolism.

Hot Room Temperature

Extended stays in warm rooms may slow metabolism as the body uses less energy to regulate temperature. Keeping a comfortable room temperature can enhance metabolism.
