Several factors come into play when determining whether you have a fast or slow metabolism. Your basal metabolic rate (BMR) is the amount of energy your body needs to survive and perform its daily functions. Your resting metabolic rate (RMR) is the actual number of calories your body burns while at rest. Knowing both will give you a better idea of your metabolic health.
Someone with a slow metabolism typically burns calories at a slower rate. This means more of their energy is stored than is used. Your general lifestyle, physical activity, sleep, and genetics will all impact your metabolism.
Not sure whether your metabolism is fast or slow? Consider these signs of a slow metabolism:
Weight gain that sticks. Since your body burns calories much slower with a slow metabolism, the nutrients and energy from the food you eat aren’t used as efficiently as someone with a fast metabolism. If you find that even when implementing a healthy diet and exercise routine you still gain weight that sticks, you may have a slower metabolism.
Blood sugar imbalance. Spikes and dips in your blood sugar levels can greatly impact your day-to-day life. Side effects include headaches, fatigue, mood swings, and craving sugary or processed high-carb foods, such as chips or cookies.
Hormone level imbalance. Some people are born with imbalanced hormone levels. Others may develop this over time as they age. If you’ve noticed a change in your skin or your hair is starting to thin, these may be signs of hormonal imbalance.
