Does Eating Cold Food Burn More Calories? The Truth Behind This Common Myth

Have you ever heard that eating cold food can help you burn more calories? Is there any science behind it? Metabolism is a complex process, but the role of temperature in metabolism is an interesting topic to explore. In this blog article, we delve into the science behind metabolism and explain how temperature affects it. We investigate whether eating cold food actually burns more calories and explore other factors affecting metabolism.

Does Eating Cold Food Burn More Calories?

Metabolism is the process by which your body converts food into energy. It’s the sum of all chemical reactions that take place in your body. When it comes to weight loss, many people are curious about whether eating cold foods can have a positive impact on their metabolism.

How Metabolism Works

Your metabolism is responsible for breaking down nutrients from food and turning them into usable energy for your body. This process involves two key steps: catabolism and anabolism.

  • Catabolism: This process involves breaking down larger molecules such as carbohydrates, proteins, and fats from the food you eat into smaller ones.
  • Anabolism: Once these small molecules have been broken down to their simplest form, they can be used to create new cells or tissues in your body.

Your basal metabolic rate (BMR) is the number of calories you burn at rest. Your BMR depends on a variety of factors, including age, sex, weight, height, and muscle mass.

The Effect of Temperature on Metabolism

Eating cold foods might cause a slight increase in metabolic rate because your body has to work harder to warm up the food to its core temperature. Studies suggest that this thermal effect of food may boost metabolism by up to 20%, but only temporarily.

This means that while eating cold or hot foods could affect your metabolism slightly throughout the day, it’s not going to make a significant difference long-term when it comes to weight loss or weight gain.

Can Cold Food Really Burn More Calories?

In conclusion; while some evidence suggests that there may be a slight boost in metabolism when eating cold foods, it’s not enough to make a significant difference in terms of weight loss or gain. However, incorporating cold food into your diet can still have other potential benefits such as aiding digestion and providing hydration.

The Science Behind Metabolism

Metabolism is the process by which our body converts food into energy for daily activities. It encompasses all the chemical reactions that occur within our cells, including breaking down food and synthesizing new molecules.

Metabolic rate

Metabolic rate refers to the speed at which our body carries out metabolic processes. It is influenced by a variety of factors such as age, gender, weight, height and activity level. Generally speaking, younger people tend to have faster metabolism due to higher muscle mass; men often have faster metabolism than women due to their tendency to carry more lean body mass. Likewise, those who lead an active lifestyle and have regular exercise routines usually possess a higher metabolic rate compared to sedentary individuals.

Factors that affect metabolism

  • Body composition:
  • The amount of muscle and fat in your body significantly affects metabolic rate – muscles burn calories more efficiently compared to fat tissues.

  • Aging:
  • The older we get, the slower our metabolism becomes due to loss of muscle mass and hormonal changes that occur with aging.

  • Heredity:
  • Sometimes your genes may predispose you to a slower or faster metabolism; however environmental factors play a big role too so it’s not all predetermined by genetics only.

  • Diet:
  • Your diet influences your metabolic rate too. Eating protein-rich foods boosts metabolism since digestion of proteins requires more energy than carbohydrates or fats do while skipping meals or eating unhealthy processed foods can slow down metabolism over time.

  • Hormones:
  • Hormonal imbalances like low levels of thyroid hormone can cause a slow metabolism, leading to weight gain and other health problems.

How food affects metabolism

The body needs a certain amount of energy to digest nutrients from foods consumed. This is called the thermic effect of food or TEF, which accounts for about 10% of daily calorie expenditure. Foods high in protein have a higher TEF percentage than carbohydrates or fats. Another crucial aspect that impacts metabolism is how much one eats -portion sizes matter- as well as meal frequency – people who eat smaller meals more frequently throughout the day oftentimes see an increase in their metabolic rate.

To maintain a healthy metabolism, focusing on good nutrition including getting enough macronutrients (proteins, fats & carbs) and micronutrients like vitamins and minerals while also incorporating regular physical activity into one’s routine is key.

The Role of Temperature in Metabolism

One critical aspect of metabolism is temperature regulation. Our bodies are finely tuned to maintain a core temperature, typically at around 98. 6 degrees Fahrenheit (37 degrees Celsius). Factors such as clothing, physical activity, and environmental conditions can impact our body’s ability to regulate temperature.

How the Body Regulates Temperature

  • The hypothalamus plays a vital role in regulating body temperature by sending signals to various parts of the body to release or conserve heat.
  • Sweating is one way that our bodies cool down as sweat evaporates from the skin, taking heat with it.
  • Shivering is another response intended to generate heat- muscles quickly contract and relax in an attempt to raise body temperature back up

The Effect of Temperature on Metabolism

The basal metabolic rate (BMR) is the amount of energy your body needs to function while resting or sleeping. It increases when your body tries to warm-up itself or compensates for cold temperatures because your metabolism gets faster while you burn more calories compared with just sitting still or exercising during moderate temperatures.

The Difference Between Brown Fat and White Fat

  • White fat: stores energy for later use whereas brown fat burns calories through thermogenesis which generates heat due to its higher concentration of mitochondria compared with white fat.
  • Brown fat acts like an internal heater allowing us not only better handle colder environments but also can help decrease obesity risk factors by speeding up metabolism.

    How Brown Fat Affects Metabolism

    Brown adipose tissue has been found to be activated when exposed to colder temperatures. The fat, which is more common in babies or children, but can be stimulated later on life as well by being regularly exposed to a cooler environment which usually leads to the burning of calories and an increase in metabolism.

    Therefore, maintaining a body temperature through internal and external factors can affect your overall metabolism by changing basal metabolic rates and increasing energy use through brown adipose tissue activation.

    The Relationship Between Cold Food and Metabolism

    How Cold Food Affects Metabolism

    Cold food, such as ice cream or smoothies, can have a temporary effect on metabolism due to the thermic effect of food. This means that the body uses extra energy to digest and absorb the nutrients from these foods, which can increase metabolic rate for a short period.

    However, this effect is relatively small in comparison to other factors that impact metabolism such as age, gender, genetics, and physical activity level.

    The Truth About The Myth of Cold Food and Metabolism

    There is a common myth that consuming cold food will slow down metabolism or cause weight gain. However, this is not scientifically accurate. It’s important to understand that weight loss occurs when there is a calorie deficit – meaning you burn more calories than you consume – regardless of whether those calories come from hot or cold foods.

    A healthy diet should consist of a variety of nutrient-dense whole foods including fruits, vegetables, lean proteins, and healthy fats – both hot or cold options can be included within these guidelines.

    The Role Of Thermogenesis In Weight Loss

    If your goal is weight loss, it’s important to create a calorie deficit through either reducing caloric intake or increasing physical activity- preferably with an equal mix of both. While thermogenesis (the increase in metabolic rate after eating) plays a small role in this effort via cold food consumption above what exists naturally in various types of ingestibles. However adding increased daily exercises routine like walking 30 minutes daily could produce more noticeable result as well staying away from high-calorie processed foods could be beneficial too.
    It’s important to keep focus on longer-term habit building rather than short-term fads.

    In summary, consuming cold foods does have a small effect on metabolism due to the thermic effect of food. However, this effect is relatively minor compared to other factors that impact metabolic rate. It’s important to prioritize a balanced and healthy diet rather than focusing solely on temperature preference of your food. Ultimately, weight loss comes down to creating a sustainable calorie deficit through healthy eating habits and physical activity alone or both in combination which could be done without any pre-request into ways specificity of partaking them

    Other Factors Affecting Metabolism

    Metabolism is influenced by many factors, aside from age and genetics. These are some of the notable ones:

    The Importance of Sleep

    Sleep deprivation can have a negative impact on your metabolism. Studies show that people who sleep less than 6 hours per night tend to have a slower metabolism, which may lead to weight gain. Lack of sleep affects hormones such as ghrelin and leptin that regulate appetite and energy expenditure. When you don’t get enough rest, your body produces more ghrelin (the hunger hormone) while decreasing levels of leptin (which suppresses appetite).

    The Effect of Stress on Metabolism

    Chronic stress can affect your metabolism in different ways. One possibility is that it stimulates the production of cortisol, known as the “stress hormone. ” High levels of cortisol can trigger changes in insulin sensitivity and blood sugar regulation, which may contribute to weight gain or metabolic disorders like diabetes.

    In addition to this metabolic effect, stress can also cause behavioral changes that impact food choices and physical activity level. Many people turn to unhealthy foods as a form of coping with stress; this type of emotional eating can disrupt overall calorie balance and further worsen metabolism.

    The Role of Exercise in Metabolism

    Daily physical activity has been linked with numerous health benefits beyond just burning calories; exercise can improve insulin sensitivity, lipid profile, muscle mass/strength, cardiovascular fitness among others.

    Aerobic training particularly increases oxygen consumption – which contributes significantly to post-exercise increased metabolic rate, especially when performed at higher intensities.  

    • Tip:   Regular exercise doesn’t have mean only high-intensity workout. There are different types of exercise that can suit you best based on your preference & lifestyle, ultimately accomplishing the same goal.


    In conclusion, while there are some studies that suggest eating cold food may boost your calorie-burning capacity slightly, the overall impact on weight loss is negligible. Factors like regular exercise, proper sleep, and a balanced diet still play crucial roles in improving your metabolism.


    1. Can drinking cold water also help with burning calories?

    Yes, drinking icy-cold water or beverages might make your body work harder to warm up which increases metabolic rate leading to caloric increase

    2. Does spicy food affect our metabolism?

    Yes, spicy foods stimulate thermogenesis – heat production inside the body – causing an increase in metabolic rate

    3. Is it better to eat few large meals or many small ones for good metabolism?

    It’s better for metabolism if you spread your calorie intake throughout the day by consuming smaller portions at regular intervals as this will help keep your metabolic rate steady and avoid spikes or dips which could undermine its efficiency
