Celsius for Weight Loss: Does Celsius Help You Lose Weight?

I’ve used Celsius for weight loss for a couple of years, and I can confidently say that Celsius Drinks help you lose weight when used correctly!

I like to start my day with a Celsius drink and a fasted walk, which helps me burn fat and kickstart my metabolism.

The combination of caffeine and green tea extract in Celsius makes it one of the best energy drinks for weight loss, along with it being one of the healthiest energy drinks.

So, does Celsius actually burn fat? 

Technically, yes—its thermogenic ingredients (like green tea extract and caffeine) increase calorie burning, even without exercise.

However, real weight loss still depends on being in a calorie deficit.

If you’re following a healthy weight loss diet and staying active, drinking Celsius can help you lose weight more efficiently.

Especially if you drink Celsius before exercising, they can promote better fat metabolism, more energy for your workouts, and more weight loss

That said, I wouldn’t recommend drinking more than one Celsius per day—too much caffeine can have negative effects.

But if used correctly, Celsius is good for weight loss, especially when combined with exercise and a balanced diet.

So if you’re wondering does Celsius work for weight loss? My experience says yes!

How Celsius Drinks Claim to Support Weight Loss

Celsius promotes its drinks as “clinically proven” to accelerate metabolism and enhance fat burning.

The brand highlights that its formula includes thermogenic ingredients, which may increase calorie expenditure and promote fat oxidation.

Unlike traditional energy drinks that rely on excessive sugar and artificial additives, Celsius is sugar-free, low-calorie, and free from preservatives or artificial flavors—making it a seemingly better choice for those focused on fitness and health.

Key Features of Celsius Drinks

As I’ve written about before, I believe Celsius is one of the healthiest energy drinks.

Here is some general information on Celsius energy drinks:

• Zero Sugar – Helps avoid excess calorie intake and blood sugar spikes.
• 200-300mg Caffeine Per Can – There is a significant amount of caffeine in Celsius drinks, which supports energy levels, alertness, and metabolism.
• Proprietary MetaPlus® Blend – Includes thermogenic compounds like green tea extract, guarana seed extract, and ginger root.
• B Vitamins – Supports energy production and overall metabolic function.

Why Celsius Drinks Are Good for Weight Loss

The main argument for Celsius as a weight-loss aid is its thermogenic effect—the ability to increase calorie burning through heat production.

Research clearly indicates that some of its ingredients may contribute to increased energy expenditure and fat oxidation, especially when combined with an active lifestyle.

Caffeine & Metabolism Boosting

Celsius contains 200-270mg of caffeine, which is known to enhance thermogenesis and fat oxidation.

12oz Celsius cans contain and Celsius on-the-go packets contain 200mg of caffeine each, while Celsius Essentials cans contain 270mg of caffeine.

Studies show that caffeine increases resting energy expenditure (REE) by 3-11% and enhances fat breakdown (Astrup et al., 1990).

Additionally, caffeine can improve exercise performance, allowing individuals to work out harder and burn more calories.

Green Tea Extract (EGCG) for Fat Burning

Celsius includes green tea extract standardized to 15% EGCG (epigallocatechin gallate), a catechin known to enhance thermogenesis and fat oxidation.

Research suggests that EGCG combined with caffeine increases fat burning by up to 17% during moderate-intensity exercise (Venables et al., 2008).

Guarana & Ginger Root for Thermogenesis

• Guarana extract is another natural caffeine source in Celsius, which may enhance calorie burning and sustain energy levels.
• Ginger root extract has been studied for its potential to increase thermogenesis and improve digestion, aiding in metabolism regulation.

These ingredients work synergistically to promote energy expenditure, making Celsius a potential tool for increasing daily calorie burn.

Does Drinking Celsius Alone Lead to Weight Loss?

While Celsius drinks contain scientifically backed thermogenic ingredients, simply drinking them without adjusting diet and exercise habits will not lead to significant weight loss.

Weight loss occurs when caloric expenditure exceeds caloric intake, meaning that Celsius should be used as part of a balanced diet and active lifestyle rather than as a magic weight-loss solution.

1. Caloric Deficit is Essential – While Celsius can increase metabolism slightly, you must still burn more calories than you consume.
2. Diet Matters More – Avoiding high-calorie, processed foods and focusing on whole, nutrient-dense meals will have a more profound impact on fat loss.
3. Exercise Enhances Results – Combining Celsius with strength training and cardio workouts maximizes its potential thermogenic benefits.

Potential Downsides of Using Celsius for Weight Loss

Although Celsius is a healthier alternative to traditional energy drinks, it is essential to be mindful of potential drawbacks.

High Caffeine Content (200-300mg Per Can)

For individuals sensitive to caffeine, consuming Celsius may lead to jitters, rapid heart rate, or sleep disturbances. Drinking it too late in the day may also interfere with sleep quality, which is crucial for weight loss and muscle recovery.

Not a Substitute for a Healthy Lifestyle

While Celsius can provide an energy boost and minor metabolic increase, it is not a replacement for healthy eating, regular exercise, and proper hydration.

Possible Overreliance on Energy Drinks

Regularly consuming Celsius or other high-caffeine beverages to compensate for lack of sleep or poor diet can lead to burnout, adrenal fatigue, and dependency on stimulants.

Best Way to Use Celsius Drinks for Weight Loss

If you want to incorporate Celsius into your weight-loss strategy, here are the best ways to do it:

• Drink It Pre-Workout: The caffeine and thermogenic ingredients can enhance endurance and fat burning during exercise.
• Pair It With Strength Training & Cardio: Use the extra energy to push harder in the gym.
• Consume It in Moderation: Limit intake to one can per day to avoid excessive caffeine consumption.
• Hydrate Properly: Since Celsius is a diuretic (due to caffeine), drink plenty of water to stay hydrated.
• Follow a Balanced Diet: Prioritize whole foods, lean proteins, healthy fats, and fiber-rich carbohydrates.

Final Verdict: Is Celsius Good for Weight Loss?

Although some people even worry that Celsius drinks cause weight gain, they can be a useful tool for boosting energy, metabolism, and exercise performance, but they are not a shortcut to weight loss.

The combination of caffeine, EGCG, guarana, and ginger provides some thermogenic benefits, but Celsius alone will not cause significant fat loss without a proper diet and exercise routine.

If used correctly, Celsius can enhance workouts, support an active lifestyle, and help maintain energy levels, making it a practical choice for those seeking a healthier energy drink alternative.

However, individuals sensitive to caffeine or relying on it excessively should proceed with caution.
