External Factors That Can Influence Your Basal Metabolism Rate

Do you often feel like you’re working against your own body? It can be frustrating when you’re trying to lose weight or maintain a healthy lifestyle, and it seems like no matter what you do, the number on the scale refuses to budge. Even if you try taking some pills that can help build muscle, it may not be effective. You may not realize it, but several external factors can influence your basal metabolic rate (BMR). In this post, you’ll learn some of the most common ones and how you can work to counteract their effects.

Physical Activity

People with active lifestyles tend to have higher BMRs because their bodies require more energy for daily activities and exercise. On the other hand, those who lead sedentary lives often have lower BMRs because their bodies don’t need as much energy. The good news is that increasing your physical activity can lead to a boost in BMR. Note that excessive exercise can actually have the opposite effect and lower your BMR. This often occurs when individuals engage in extreme or prolonged periods of intense training, causing their bodies to enter a state of stress and ultimately decrease metabolism as a survival mechanism.


When it comes to BMR, not all calories are created equal. The type of food you consume can have an impact on your BMR. A diet high in processed and refined foods can lead to weight gain and a decrease in metabolism. In contrast, a diet rich in lean proteins, healthy fats, and complex carbohydrates can aid in boosting metabolism. Additionally, the timing of your meals can also affect your BMR. Skipping meals or going for long periods without eating can cause your metabolism to slow down, while consistently fueling your body with regular meals can help maintain a higher metabolic rate.

Sudden Temperature Changes

Did you know that sudden temperature changes can also affect your BMR? Studies have shown that exposure to cold temperatures can increase metabolism, as the body must work harder to maintain its core temperature. On the other hand, being in a hot environment can decrease BMR as the body expends energy to cool itself down. One way to counteract this is by ensuring that you dress appropriately for the weather and maintain a comfortable temperature in your home or workspace.

Drugs and Medications

Stimulants such as caffeine or amphetamines can temporarily increase metabolism, while certain antidepressants and beta-blockers can slow it down. Talking to your doctor about any potential effects your medication may have on your metabolism before making any changes to your diet or exercise routine.

So what’s the takeaway? Your BMR is influenced by various external factors. Still, the good news is that many of them are within your control. Incorporating regular physical activity, maintaining a balanced diet, and being mindful of sudden temperature changes can all help boost your metabolism and support your overall health and well-being. Always consult your healthcare provider before making any significant changes to your lifestyle.
