Why Does My Fat Burner Make Me Hot?

Have you ever taken a fat burner and noticed you get a bit warm, start sweating bullets, or notice your heart rate increase slightly? Then you’ve just experienced thermogenesis firsthand. You’ve probably seen on your fat burner tub something like “Thermogenic blend”, but what causes thermogenesis? Does it actually translate to fat loss? Let's find out.

What’s Thermogenesis?

Thermogenesis is your body’s natural heat production. The fuel for this fire is calories. Pairing that with a calorie deficit, and hard training, you’ve got a one-way ticket to lean-ville.  When supplement companies found this out, they packed their fat burners with ingredients that amplify it. 

Caffeine: The King Of Thermogenesis

Caffeine is the champion of thermogenics, it’s in the majority of your fat burners for a reason. Stimulating the nervous system and kickstarting lipolysis, the breakdown of stored fat for energy. Studies say that depending on dosages and tolerances, it can boost metabolic rate by 3-11%. Plus, it has the added benefit of giving you a boost of energy.

One thing to look out for is your body adapting to caffeine over time, which can reduce its effects. If your fat burner has a heavy hit of caffeine, make sure you’re cycling it so that its thermogenic effects stay strong.

Capsaicin: Turning Up The Heat

Ever noticed that you get a bit sweaty when you’re eating spicy food? That’s capsaicin working its magic. Found in chilis and other spicy foods, this compound activates receptors that signal the body to produce heat. Research shows that capsaicin can increase the calories you burn at rest, as well as help burn fat. This makes it a powerful thermogenic in fat burners.

Unlike caffeine, you don’t build up a tolerance for capsaicin. It’s also been shown to reduce appetite. It’s a two-for-one deal! One thing to look out for is higher dosages can cause digestive discomfort.

Green Tea Extract: A Heated Sidekick

Green tea extract, specifically EGCG (epigallocatechin gallate), an antioxidant found in most teas, works with caffeine to enhance thermogenesis. This combo stops the breakdown of norepinephrine, a hormone that helps your body break down fat.

When by itself, the fat oxidation of green tea extract is relatively mild. However, when mixed with caffeine, green tea extract saw a 17% boost in fat oxidation. In most stim fat burners, you’ll see these two paired together.

Synephrine: The Safer Ephedrine Alternative?

If you go way back, you’ll probably see a few pre-workouts and fat burners with ephedrine, a powerful stimulant and metabolism booster. Due to multiple heart health issues that it caused, it was banned. Synepherine, found in bitter orange extract, has been found to mildly mimic those fat burning effects, without the risk of a heart attack.

Even though it has effects on its own, there’s some research that suggests synephrine is most effective when combined with other stimulants, like caffeine. This makes a heightened thermogenic effect, but be careful with dosages, as stacking stimulants can risk more side effects.

Do Thermogenics Work?

Putting it short: yes, but it isn’t going to do it magically. Thermogenics can boost the calories and fat you burn, but you can’t supplement your way out of a poor diet and lack of exercise. Treating thermogenics as an enhancement to your diet and training will make them shine the brightest. Remember to be safe with stimulants, and monitor your intake to mitigate side effects. Happy burning!
