Does Celsius Burn Fat? A Pro Athlete & Nutritionist Explains

Does Celsius burn fat, or is it just another unhealthy energy drink? 

Celsius drinks won’t help you burn fat if you consistently eat poorly and consume far more calories than you burn, but when paired with a healthy diet and exercise, their 200 mg of caffeine and 50 mg of EGCG per serving can support fat burning by boosting your metabolism, increasing fat oxidation, improving workout performance, and mildly suppressing appetite.

As a professional basketball player with a Master’s Degree in Nutrition Education and over fifteen years of experience optimizing my body composition for peak performance, I often use Celsius instead of pre-workout supplements or other energy drinks to have better workouts and maintain the body composition I need to succeed.

While it’s not a miracle fat burner, Celsius can help you burn fat by boosting energy, increasing calorie burn, and mildly suppressing appetite, if used strategically.

To quickly answer the main question: “Does Celsius actually burn fat?” Based on current research and personal results, the answer is yes, under the right conditions.

If you’re searching for a clean energy drink that can increase fat-burning potential, reduce cravings, and fit into a healthy lifestyle, Celsius drinks are a smart choice. 

However, as with any energy drink, moderation is key to avoiding potential side effects from high caffeine intake.

Additionally, for those with a busy lifestyle, I suggest Celsius On-the-Go packs as a convenient way to get these benefits.

What are Celsius Drinks and Why Do People Use Them for Fat Burning?

Celsius drinks are energy beverages designed to provide energy, increase metabolism, and support fat loss.

They contain a blend of ingredients like caffeine, green tea extract (EGCG), guarana, ginger, and B vitamins.

Each 12-oz can has 200 mg of caffeine and is marketed as a pre-workout or daily energy boost.

Unlike many traditional energy drinks, Celsius contains no artificial preservatives, colors, or flavors.

These drinks are especially popular among people looking for clean energy and potential fat-burning benefits.

Understanding the Fat Burning Process

Weight loss refers to a reduction in overall body weight, which can come from fat, muscle, water, or even glycogen stores.

For example, rapid weight loss on a low-carb diet is often due to water loss rather than actual fat reduction.

Fat burning, on the other hand, specifically refers to the process of oxidizing stored body fat for energy, often triggered by a calorie deficit, exercise, or metabolic stimulants like caffeine and EGCG.

You can lose weight without burning much fat, especially through crash dieting or dehydration.

However, true body recomposition requires preserving muscle and targeting fat loss through smart training, proper nutrition, and metabolism-boosting strategies.

So when asking “Does Celsius burn fat?”, the goal is not just to drop pounds, but to increase fat oxidation and preserve lean mass, which are two crucial components for sustainable results.

What Ingredients in Celsius Drinks Help You Burn Fat?

If you are wondering how does Celsius burn fat, you simply need to look at and understand its ingredients.

Several key ingredients in Celsius drinks contribute to fat burning by stimulating metabolism, increasing energy expenditure, and enhancing fat oxidation.

These compounds work synergistically to support weight loss, especially when combined with exercise and a calorie-controlled diet.

Caffeine

Caffeine is a well-known thermogenic compound that boosts your resting metabolic rate, increases lipolysis (fat breakdown), and improves workout performance.

It stimulates the central nervous system, allowing your body to burn more calories and fat, even at rest.

There is 200mg of caffeine in Celsius cans and packets and 270mg of caffeine in Celsius Essentials.

Green Tea Extract (with EGCG)

Celsius drinks contains 50 mg of EGCG (epigallocatechin gallate), the most active catechin in green tea.

Using green tea extract for weight loss is a popular approach because research indicates it increases fat oxidation during exercise, promotes thermogenesis, and may help regulate body weight by improving insulin sensitivity and reducing fat storage (Hodgson et al., 2013).

Guarana Extract

Guarana is a natural source of caffeine that delivers sustained energy and stimulates thermogenesis.

It may also reduce fatigue, helping you stay active longer and burn more calories throughout the day.

Ginger Root Extract

Ginger has mild thermogenic properties and may support digestion and metabolic function.

Some research suggests it can help control appetite and improve blood sugar regulation, both of which are important for fat loss (Khandouzi et al., 2015).

Chromium

Chromium supports insulin sensitivity and blood glucose control, which can help your body utilize carbohydrates more efficiently and reduce the likelihood of fat storage after meals (Havel, 2004).

While not a direct fat burner, it aids in metabolic health, which supports long-term weight management.

Taurine

Taurine contributes to cellular energy production and exercise performance (Kurtz et al., 2021).

Although it’s not directly linked to fat oxidation, taurine helps reduce fatigue and supports better training sessions, indirectly enhancing fat-burning potential.

How Does Celsius Burn Fat?

Celsius drinks contain a blend of natural fat burning ingredients like caffeine, green tea extract, guarana, and ginger, which work synergistically to boost your metabolic rate and promote fat-burning.

But, does Celsius actually burn fat?

Many athletes and fitness enthusiasts swear by it, and from my experience as a professional athlete, it’s clear that the right products can help maximize performance and results.

This unique combination provides not only an energy boost for your workouts but also improves your body’s ability to oxidize fat, making Celsius drinks one of the best energy drinks for weight loss.

Here are some of the reasons Celsius does burn fat and help with your weight loss goals:

Appetite Suppression & Calorie Control

Celsius’s appetite suppression effects stem primarily from its caffeine and green tea extract.

Caffeine, a natural stimulant, has been shown to reduce hunger signals temporarily by influencing hormones like ghrelin, which triggers hunger, and increasing catecholamines that curb appetite.

The green tea extract, containing EGCG (epigallocatechin gallate), can also subtly support these effects, making it easier to avoid excessive snacking or overeating.

Although this suppression is generally mild and temporary, it can be beneficial for those aiming to reduce calorie intake without feeling deprived.

However, it’s important to remember that the appetite-suppressing effects of Celsius vary among individuals, and for best results, it should complement a well-planned diet rather than replace mindful eating habits.

Thermogenesis

The primary mechanism by which Celsius aids in weight loss is through thermogenesis, which is the process of raising your body’s internal temperature, which results in increased calorie burn.

Celsius contains 200 mg of caffeine per can and additional green tea extract which can significantly increase metabolic rate and fat oxidation.

This heightened thermogenic effect raises your metabolic rate, leading to greater calorie burn, even at rest (Hursel & Westerterp-Plantenga, 2010).

Caffeine also stimulates the central nervous system, enhancing energy and endurance during workouts, which helps improve fat oxidation and overall weight loss efforts.

For example, one study published in Nutrients demonstrated that caffeine not only boosts exercise performance but also increases the rate of fat oxidation during workouts, allowing for more effective fat burning​.

Additionally, a study published in The American Journal of Clinical Nutrition found that green tea extract, particularly its catechins, can increase fat oxidation both at rest and during exercise, leading to greater overall fat loss​.

Importantly, each can of Celsius is within the safe daily limit of caffeine for most adults, as long as total caffeine consumption from all sources does not exceed 400 mg per day.

While Celsius is generally safe to drink, it’s important to monitor your overall caffeine intake to avoid potential side effects like jitteriness or insomnia.

By consuming Celsius before your workout, you can maximize these thermogenic effects, leading to more efficient calorie burning and faster results.

Blood Sugar & Insulin Response Control

Celsius drinks also contain several vitamins and minerals that support metabolism, but chromium stands out for its role in blood sugar regulation.

Chromium improves insulin sensitivity, helping the body manage blood sugar levels more effectively.

By improving insulin function, chromium stabilizes blood glucose levels, reducing the chance of sudden spikes and crashes that can lead to fat storage and cravings.

While chromium doesn’t directly increase fat oxidation like caffeine or green tea extract, it supports metabolic health by optimizing nutrient use and helping maintain steady energy levels throughout the day, indirectly aiding weight management efforts.

Promoting Better Workouts

One of the most underrated ways Celsius supports fat loss is by improving workout performance, which is a key factor in maximizing calorie burn and improving body composition.

The 200 mg of caffeine per can increases alertness, reduces perceived effort, and boosts endurance, all of which help you train harder and longer.

Caffeine has been shown to improve performance in both aerobic and anaerobic activities, which directly contributes to greater fat oxidation and energy expenditure during exercise (Spriet, 2014).

Additionally, ingredients like guarana and taurine promote mental focus and reaction time, making workouts feel more dialed-in and productive.

From my own experience as a professional athlete, the mental clarity and sustained energy Celsius provides can help turn an average session into a fat-burning, muscle-sculpting workout.

Whether it’s lifting heavier, running farther, or just staying motivated through a demanding training session, Celsius gives you the edge to push your limits, and that’s where real fat burning happens.

By promoting better workouts, Celsius doesn’t just passively boost your metabolism; it activates your full potential to burn fat more efficiently through movement and effort.

How to Use Celsius Drinks to Burn Fat

Celsius drinks can be a powerful tool to help burn fat, but they should be integrated into a proper weight loss strategy for the best results.

Here are some tips on how to use Celsius to burn fat:

Daytime Consumption

Aiming for a moderate caloric deficit of around 500 calories per day is ideal for sustainable weight loss, allowing you to safely lose to 1–2 pounds per week without depriving your body of essential nutrients.

Extreme calorie cuts can actually slow metabolism and hinder fat-burning, making steady, moderate reductions more effective.

Celsius can support this approach by boosting energy and mildly curbing appetite, making it easier to maintain a calorie deficit without feeling overly hungry or fatigued.

Even on rest days, Celsius can help maintain an active metabolism.

Drinking it in the morning or early afternoon can provide a steady energy boost and increases thermogenesis, keeping your metabolism engaged throughout the day.

With each can containing 200 mg of caffeine, it’s best to limit intake to one or two cans daily to prevent side effects like jitters or sleep disturbances, ensuring you enjoy its benefits without discomfort.

For those needing guidance, following my diet plan for weight loss can further help sustain this deficit while building a healthy relationship with food.

Pre-Workout

Drinking Celsius before a workout is one of the best ways to use Celsius drinks to burn fat, because they increase fat oxidation during exercise, helping your body tap into stored fat as a fuel source.

To optimize these effects, consume Celsius about 15-20 minutes before your workout.

This timing allows the 200 mg of caffeine and other thermogenic ingredients to elevate your metabolism and energy levels as you start exercising, promoting greater calorie burn and improved performance.

On-the-Go Energy & Fat-Burning Support

For those with hectic schedules, Celsius On-the-Go packets, available on Amazon, are the perfect solution.

These portable packets can be easily carried in your bag and mixed with water whenever you need a metabolism-boosting drink, whether you’re at the gym, at work, or out and about.

If you prefer to buy in bulk, you can find large packs of Celsius cans at Costco or BJ’s Wholesale.

Otherwise, the on-the-go packets are convenient and cost-effective, making them ideal for regular users who want to maintain a steady supply.

By combining a balanced, nutrient-dense diet with Celsius’s fat-burning benefits, you can achieve sustainable weight loss and improve your overall fitness journey.
