Celsius energy drinks can increase metabolism through thermogenic ingredients like caffeine and green tea extract.
The Science Behind Celsius and Metabolism
Celsius energy drinks have gained popularity for their promise to boost energy and enhance metabolism. But what does science say about this claim? The key to understanding how Celsius affects metabolism lies in its ingredients. Celsius contains caffeine, green tea extract, guarana, and other components known for their thermogenic properties—meaning they can raise the body’s heat production and calorie burning rate.
Caffeine is a well-documented stimulant that activates the central nervous system, increasing heart rate and metabolic rate. Green tea extract provides catechins, especially epigallocatechin gallate (EGCG), which have been shown to promote fat oxidation and slightly increase metabolic rate. Guarana adds an extra caffeine punch, amplifying these effects.
Together, these ingredients create a synergistic effect that can temporarily accelerate metabolism. However, the degree of this increase varies depending on individual factors such as tolerance to caffeine, body composition, and overall health.
How Much Does Celsius Actually Boost Metabolism?
Studies on similar thermogenic beverages suggest a modest increase in resting metabolic rate (RMR). For instance, research indicates that caffeine alone can raise RMR by approximately 3-11% over several hours post-consumption. When combined with green tea catechins, this effect might increase slightly.
Celsius claims their formula can boost metabolism by up to 12%, but independent studies specifically testing Celsius are limited. The actual metabolic boost likely falls somewhere between 5-12%, which translates to burning an extra 50-150 calories per day depending on baseline metabolism.
This boost sounds promising but keep in mind it’s temporary. The body often develops tolerance to stimulants like caffeine after repeated exposure, reducing the long-term metabolic impact.
Key Ingredients Driving Metabolic Acceleration in Celsius
Understanding the core components of Celsius helps clarify why it might accelerate metabolism. Here’s a breakdown of the primary ingredients responsible for its effects:
| Ingredient | Role in Metabolism | Typical Amount per Serving |
|---|---|---|
| Caffeine | Stimulates central nervous system; increases heart rate and calorie burn. | 200 mg |
| Green Tea Extract (EGCG) | Catechins enhance fat oxidation and thermogenesis. | 100 mg |
| Guarana Seed Extract | Adds natural caffeine; boosts energy and metabolism. | Sourced within proprietary blend (~50 mg caffeine equivalent) |
Caffeine is the star player here—200 mg per can is roughly equivalent to two cups of coffee. This amount is enough to stimulate alertness and elevate metabolic rate without typically causing jitters in most adults.
Green tea extract complements caffeine by promoting fat breakdown through its antioxidant compounds. Guarana adds an additional source of natural caffeine, enhancing overall stimulant effects.
The Thermogenic Effect Explained
Thermogenesis refers to heat production in the body during digestion or physical activity. Ingredients like caffeine and EGCG stimulate thermogenesis by activating the sympathetic nervous system. This leads to increased energy expenditure even at rest.
The rise in body temperature requires burning more calories, which over time could support weight management efforts if paired with healthy diet and exercise.
However, this effect isn’t permanent or massive—it’s more like a metabolic nudge rather than a drastic overhaul of your calorie-burning machinery.
The Role of Caffeine Tolerance in Metabolic Response
One important factor influencing whether Celsius accelerates metabolism effectively is your individual caffeine tolerance. People who regularly consume high amounts of caffeine may experience diminished metabolic boosts over time because their bodies adapt.
Tolerance means the same dose produces less stimulation as receptors become less sensitive. So if you’re used to drinking multiple cups of coffee daily or taking other caffeinated supplements, the impact from a single Celsius drink might be minimal.
Conversely, if you rarely consume caffeine, even one can could noticeably increase your alertness and calorie burn temporarily.
Caffeine Sensitivity Spectrum
- Low sensitivity: May experience strong effects including jitteriness or rapid heartbeat; higher metabolic boost initially but risk overstimulation.
- Moderate sensitivity: Balanced response with noticeable energy increase and mild metabolic acceleration.
- High tolerance: Minimal stimulation; reduced impact on metabolism due to receptor desensitization.
Knowing where you fall on this spectrum helps set realistic expectations for how much Celsius will accelerate your metabolism.
The Impact of Other Lifestyle Factors on Metabolism with Celsius
While Celsius contains ingredients that can speed up metabolism somewhat, lifestyle choices also play huge roles in determining your overall metabolic rate:
- Diet: Eating protein-rich meals increases thermic effect of food (TEF), enhancing calorie burn during digestion.
- Physical Activity: Regular exercise boosts muscle mass which raises basal metabolic rate (BMR).
- Sleep:
- Hydration:
Drinking Celsius won’t override poor lifestyle habits but may provide a temporary edge when combined with healthy behaviors.
The Synergy Between Celsius and Exercise
Taking Celsius before workouts might improve performance due to increased alertness from caffeine. Enhanced exercise intensity or duration burns more calories both during activity and afterward via excess post-exercise oxygen consumption (EPOC).
This synergy means that while Celsius alone offers modest metabolic acceleration, pairing it with physical activity maximizes overall calorie expenditure throughout the day.
The Safety Profile of Thermogenic Ingredients in Celsius
It’s essential to consider safety when consuming products designed to accelerate metabolism through stimulants. Although generally safe for healthy adults when consumed responsibly, some caveats exist:
- Caffeine Overdose Risk:
- Sensitivity Reactions:
- No Artificial Preservatives:
- No Sugar:
Moderation is key—stick to recommended serving sizes and avoid mixing with other stimulants like pre-workout supplements or high-caffeine coffees throughout the day.
Celsius vs Other Energy Drinks: A Healthier Choice?
Compared to traditional energy drinks packed with sugar and artificial additives, Celsius stands out as a cleaner option focused on natural ingredients that support metabolism without unnecessary extras.
This makes it attractive for fitness enthusiasts looking for an energy lift combined with potential fat-burning benefits without excess sugar calories that could derail weight management goals.

Frequently Asked Questions
Does Celsius accelerate metabolism through its ingredients?
Yes, Celsius contains thermogenic ingredients like caffeine, green tea extract, and guarana. These components work together to temporarily increase the body’s heat production and calorie burning, which can accelerate metabolism for a short period after consumption.
How much does Celsius accelerate metabolism compared to other drinks?
Celsius may boost resting metabolic rate by approximately 5-12%, which is slightly higher than many similar thermogenic beverages. This translates to burning an extra 50-150 calories per day, though individual results can vary based on factors like caffeine tolerance and body composition.
Is the metabolism acceleration from Celsius permanent?
The metabolic boost from Celsius is temporary. Over time, the body can develop tolerance to stimulants like caffeine, which reduces the long-term effect on metabolism. Regular use may diminish the drink’s ability to accelerate metabolism as effectively.
What role does caffeine in Celsius play in accelerating metabolism?
Caffeine stimulates the central nervous system, increasing heart rate and metabolic rate. In Celsius, the 200 mg of caffeine per serving helps raise calorie burn and temporarily speeds up metabolism through this stimulation.
Can green tea extract in Celsius accelerate metabolism on its own?
Green tea extract contains catechins like EGCG that promote fat oxidation and slightly increase metabolic rate. While effective on its own, in Celsius it works synergistically with caffeine and guarana to enhance overall metabolic acceleration.
The Bottom Line – Does Celsius Accelerate Metabolism?
