Summary: Geeks Health is a trusted fitness and general health information source. One paramount weight management information regards the impact of body temperature on weight loss and detoxification. The human body temperature is easy to measure and says a lot about a person’s health. Further, our internal body temperature greatly affects how our body functions and how we ward off cravings. Here are a few ways the internal body temperature will affect body metabolism and ultimately affect weight loss. 

Determines your Metabolism Rate

In a recent review article, Geeks Health expert believe once you lose weight, your body’s metabolism drops significantly. This is one of the reasons dieting patients want to keep warm all the time. When the body’s metabolism is high, there is more weight loss due to increased fat burning, and once you achieve the right weight, the metabolism slows. Understanding your body temperature is a great way to help keep track of determining your metabolism response as you lose weight. 

High Temperatures

According to previous research, high core body temperatures tend to increase metabolism . The Clinical and Climatological Association report in 2019 indicates an increase in the temperature leads to an increased metabolic rate. Further, high metabolism rates also result from increased temperatures, which aid in fat-burning and ultimately lead to weight loss.  The reports further indicate that once there is a degree rise in your body temperature, the metabolism rate increases by 10-13 percent. This means you could add 100 to 130 per day if your regular diet consists of 200 calories daily. The human body temperature may account for up to 50 percent of energy expenditure.

Cool Temperatures

According to the report, cooler body temperature appears to lower metabolic rates. The reports note that when the temperature drops by 1 degree Celsius, there is a subsequent decrease in temperatures, which may expend 100 to 130 fewer calories each day.

Being cold helps you Lose weight

In separate research published by researchers at the University of Geneva, cold body temperatures affect the functioning of intestinal bacteria, which further causes a microbial shift. In this manner, the body can burn fat stores, improving glucose metabolism to help you lose weight.

The Internal Body Temperature Keeps Your Appetite in Check

When exposed to cold for a long time, thyroid hormones are released, raising the temperature and increasing the metabolic rate. Nonetheless, the appetite levels tend to flow with the temperature check, which means the lower your room is, the higher your appetite levels become. Appetite levels and temperature levels go hand in hand. We crave high-calorie and high-carbohydrate foods, which provide the body with instant heat to warm up.  During the cold seasons, like the winter, the cool temperatures lead to decreased serotonin levels, which causes seasonal depression. The cravings for carbs further compensate for the low temperatures and low serotonin. 

Body Temperature and Weight Loss

A recent study has found that a biological inability creates core body heat, which is linked to obesity. The research found evidence of diurnal thermogenic handicaps in obesity. According to the report, obese people have low internal temperatures. If they increase their body temperature levels, they will shed more weight. Further, obese people have a thick subcutaneous layer that provides insulation to heat loss. Losing weight for obese people is, therefore, challenging because of this increased heat dissipation. Due to the ADP, Adipose Tissue, it is harder for them to expend energy as heat. Scientifically, the brown adipose tissue produces heat by bringing triglycerides found in intracellular lipid droplets. The brown fat tissues have an interlinked set of compounds known as branched amino acids, BCAAs, that play an essential role in energy expenditure.

Body Temperature May Affect Weight Loss through Stress Levels

According to a recent study on mice and humans, stress significantly impacts body temperature. The results showed that stress induced hyperthermia. According to some further studies, long-term stress leads to a chronic rise in temperatures in the body, which affect weight loss and body metabolism. The temperature rise is because of the release of the adrenaline hormone that mediates the body’s fight or flight response. It further stimulates liver heat production, enhancing other adaptive changes. Notwithstanding, the study explains how stress may cause fever with no underlying illness and without an inflammatory process like an injury. In 2020, a study on rats showed that stress response affects the hypothalamus. The exact mechanism works for humans.


Body temperature is easy and fast to measure. You do not need any glucose meters or skin pricking. The body’s metabolic rate rises with rising body temperatures. Consequently, we burn more calories. More heat is generated, raising the body temperature and creating a positive feedback process. The metabolic rate may decrease by up to 7% for every degree drop in body temperature. For an average obese person, raising body temperatures by up to 4 degrees can burn more calories due to the rising temperature and two due to daily physical activities.
