The book was written by Brad Pilon, best-known for his intermittent fasting research. Brad wrote a book called Eat Stop Eat that sold 250,000 copies, introducing thousands of people to intermittent fasting benefits.

In The Book on Heat, Brad discusses the connection between temperature and body weight, temperature and performance, and temperature and longevity, among other connections.

What Will You Learn in The Book on Heat?

The Book on Heat aims to make dieting easier by telling you how body temperature impacts weight loss. By manipulating your body temperature, you could accelerate weight loss results.

According to Brad’s research, body temperature is linked to dieting, growth hormone production, hunger hormone production, fat burning, and other areas.

Brad presents this information in no-nonsense language. He’s done his research, but The Book on Heat is written in a way that’s easy for anyone to understand. It explains the science supporting Brad’s claims, and then it explains how to use this information in your day-to-day diet.


Brad admits he was skeptical about body temperature and weight loss when he first started his research. In fact, he claims he was also skeptical about intermittent fasting before he wrote Eat Stop Eat. However, after doing the research, Brad believes there’s a close connection between body temperature and performance – and anyone can use this connection to accelerate weight loss results.

Things Affected by Body Temperature

Brad’s research proves that all of the following are impacted by body temperature:

  • Dieting and weight loss
  • Human growth hormone (HGH) production
  • Ghrelin (the hunger hormone) production
  • Leptin (another hunger and fat burning hormone) production
  • Muscle growth and exercise performance
  • Metabolism and energy
  • Inflammation response, cleansing, renewal, and more
  • And more

Brad explains all of these things and more in The Book on Heat. He explores how body temperature is connected to all of these things – and how you can use this information for your own health and wellness goals.

Topics Covered in The Book on Heat

The Book on Heat explains how body temperature impacts different parts of your health and wellness – from weight loss to athletic performance.

Some of the topics covered in The Book on Heat include:

How the temperature influences human metabolism

Why body temperature is “a driving force” in fat gain and fat loss

How exposure to the cold can blunt the fat loss effects of exercise

How a fast metabolism does not always lead to weight loss, and why it could lead to fat gain in some cases

How body temperature is linked to weight loss, hormone production, leptin, ghrelin, exercise performance, metabolism, energy, inflammation, cellular renewal, and more

How to implement body temperature exercises and therapies in your day-to-day life, from exercising in cold weather to spending time in saunas

Scientific Evidence for The Book on Heat

Brad cites 300 references across 70+ years of research in The Book on Heat. He’s done his work, and his claims are cited by professional research in peer-reviewed journals. You can check Brad’s research at his References page, which he publishes upfront.


There’s certainly a connection between body temperature and weight loss. In fact, there’s a connection between body temperature and most body processes. When you have a fever, it means your body is fighting an infection, for example.

Studies show that obese people have lower body temperatures than slimmer people. That’s because fat tends to be cooler than lean muscle. However, studies show that body temperature goes beyond fat and lean muscle mass: sedentary people tend to have lower interior temperatures than active people. In this 2009 study, researchers found that skinnier people had better metabolic efficiency than overweight people, which is why skinnier people tended to have higher body temperatures than overweight people.

Some weight-loss experts recommend exercising in cold air because it helps you lose weight. As explained by this 2014 article, exercising in cold air appears to use more energy than exercising in warmer temperatures. Your body needs to burn more calories to stay warm. It’s not a significant difference (you won’t burn twice as many calories, for example), but it could add up to large long-term gains.

Exercising in cold temperatures seems to help with a type of fat called brown fat particularly. Brown fat is particularly affected by cold. One study found that brown fat can account for up to 30% of the body’s energy budget. By exercising in cold temperatures, you’re forcing your brown fat to burn more energy than it would at room temperatures, which could accelerate weight loss results.

In fact, studies show you don’t even need to exercise in cold temperatures to enjoy these benefits: just sitting in a cold room could lead to increased fat burning. A group of researchers in Japan found regular exposure to mild cold (of around 62 degrees Fahrenheit) “may be a healthy and sustainable way to help people lose weight.” Similarly, researchers found that warm, cozy homes could be associated with weight gain. By keeping your home at a colder temperature, you could save on your energy bill and lose weight.

Body temperature isn’t just linked to weight loss: it’s also linked to disease. A fever is a temporary increase in your body temperature, often due to an illness. When you have a fever, it’s a sign that something out of the ordinary is going on inside your body. If your fever is 103 F (39.4 C) or higher, it’s a cause for concern. If you have a fever, you may experience sweating, chills, headache, muscle aches, loss of appetite, and other symptoms.

Certain disorders are linked with body temperature. A healthy human generates heat capable of raising body temperature by 1 degree Celsius per hour. However, some people have abnormally high or low body temperatures, which could be a sign of a serious illness. Some people struggle to keep their body at a normal temperature. They produce too much or too little heat, leading to health problems.

Brad also discusses the health benefits of saunas. Multiple studies have shown that saunas are linked with powerful health benefits – from circulation to weight loss. In this 2018 review study, researchers analyzed dozens of studies on saunas involving a total of 3,855 participants. Researchers concluded that regular dry sauna bathing “has potential health benefits.” Researchers found a connection between sauna usage and cardiovascular health, body weight, inflammation, cholesterol, stress markers, and other metrics. Sauna usage was linked with better overall health and wellness. When you sit in a sauna, you raise your body temperature, which is why Brad included sauna bathing in The Book on Heat.

Brad discusses all of this information and more in The Book on Heat, exploring how heat, weight loss, disease, and more are all interconnected.
