Six studies have been conducted on Celsius by U.S. accredited scientific research facilities according to strict scientific standards. Multiple studies have shown that drinking Celsius may result in burning calories and providing lasting energy and when drinking a great tasting Celsius 15 minutes before exercise, Celsius may reduce body fat while building lean muscle.†*
Studies show Celsius may have the ability to positively impact body composition when consumed 15 minutes prior to moderate exercise by reducing body fat while building lean muscle.†* Lean muscle is more metabolically active which means your body may burn calories more efficiently throughout the day.
Study 1 — 2005
Metabolic responses to the acute ingestion of two commercially available carbonated beverages
This research study, conducted with the Ohio Research Group of Exercise and Sports Nutrition, was a placebo-controlled, double-blind, cross study to compare the short term effects on metabolic rate of Celsius compared to a commercially available diet soda. The findings indicated that drinking 12oz of Celsius has thermogenic, or calorie-burning, properties where the diet soda did not.
Study 2 — 2007
Acute effects if ingestion a commercial thermogenic drink on changes in energy expenditure and markers of lipolysis
A second study was conducted in the Applied Biochemistry and Molecular Physiology Laboratory in the Department of Health and Exercise Science at the University of Oklahoma and was presented at the International Society of Sports Nutrition Annual Scientific Symposium held in Las Vegas. This research further validates the effects of Celsius on boosting calorie burning, by means of increasing metabolism. The university scientist reported that both male and female study participants consuming just one 12 ounce can of Celsius burned an average of 100 more calories than a placebo over a three-hour period.
“This second study confirms that Celsius burns calories, increases metabolism and provides an energy boost over a three hour period,” said Chad Kerksick, Ph.D., who served as Chief Researcher for the project at the University of Oklahoma. “Specifically, this study found that Celsius helped individuals burn an average of over 100 calories more than those participants consuming the placebo. Additionally, the new study found that participants who consumed only one serving of Celsius maintained a 65% greater level of calorie burning over a similar group of men and women that consumed a placebo.” Continuing, Dr. Kerksick said, “In my opinion by investing in additional research, Celsius, Inc. is building a conclusive body of research demonstrating clinical evidence of functionality for calorie-burning.”
Study 3 — 2007
Prolonged impact of ingesting a commercial thermogenic drink for a 28-day period
This third study was conducted at the Applied Biochemistry and Molecular Physiology Laboratory, Department of Health and Exercise Science at the University of Oklahoma. The study reviews the effects of daily consumption of a 12 oz can of Celsius over a 28 day period and determines its effect on metabolism as well as other important health markers. The results confirm that over the prolonged period, Celsius was shown to raise metabolism and burn an average of more than 100 calories per single serving throughout the entire study. It also shows that Celsius did not produce clinically significant changes for important health markers such as: lipid panel and fasting glucose, (triglycerides, total cholesterol, HDL, LDL, total cholesterol: HDL ratio, glucose), kidney enzymes, liver enzymes, complete blood count, resting heart rate, systolic or diastolic blood pressure during the study.
Study 4 — 2008
Pre-workout consumption of Celsius enhances the benefits of moderate exercise on body consumption and cardio-respiratory fitness
This study was conducted at the Applied Biochemistry and Molecular Physiology Laboratory, Department of Health and Exercise Science at the University of Oklahoma. The functional beverage Celsius® has recently been shown, after acute and chronic (28 days) consumption, to increase resting metabolism and serum blood markers of lipolysis in healthy, college-aged men and women. The purpose of this study was to examine the combined effects of a 10-week exercise program while consuming Celsius® on body composition and cardio-respiratory fitness changes in sedentary men and women. The results showed 93% more fat loss, 50% more muscle gain, 62% improved cardio fitness, and 32% increased endurance among the Celsius group compared to those drinking a placebo. “This study suggests that Celsius provides a significant, additive adaptation to the benefits of regular exercise,” stated Jeffrey R. Stout, Ph.D., who served as the Chief Researcher on the study, at the University of Oklahoma. “Specifically, consuming Celsius prior to exercise appears to augment ones’ training response to both aerobic and resistance (weight) training. Furthermore,” said Stout, “because we didn’t observe a statistically significant difference in strength between groups, but instead found significant improvements in body composition and cardiorespiratory fitness in those consuming the Celsius beverage, there appears to be preferential sequestering of fat for fuel, occurring both during exercise and while at rest. The same findings were previously reported out of Dr. Kerkisk’s lab.” Dr. Stout concluded by stating, “These are very interesting findings that, in my opinion, will set the tone for how people maximize their workouts. – Now it can be scientifically supported that, by consuming a pre-workout calorie burning beverage, a person can improve their response to exercise; however, these claims are unique to Celsius.”
Study 5 - 2009
Low-calorie thermogenic beverage and exercise improves body composition and lipid profile in overweight and obese women.
Our fifth study, conducted by the Applied Biochemistry & Molecular Physiology Laboratory of University of Oklahoma, combined Celsius with exercise. This 10-week placebo-controlled, randomized and blinded study was conducted on a total of 27 previously sedentary overweight and obese female subjects. Participants were randomly assigned into one of two groups: Group 1 consumed one serving of Celsius per day, and Group 2 consumed one serving of an identically flavored and labeled placebo beverage. Both groups participated in 10 weeks of combined aerobic and weight training, following the American College of Sports Medicine guidelines of training for previously sedentary adults. No changes were made to their diet. The results showed that consuming a single serving of Celsius prior to exercising may improve cardiovascular health and fitness and enhance the positive adaptations of exercise on body composition. According to the preliminary findings, subjects consuming a single serving of Celsius lost significantly more fat mass and gained significantly more muscle mass when compared to exercise alone - a 46% greater loss in fat, 27% greater gain in muscle mass, respectively.
The study also confirmed that subjects consuming Celsius significantly improved measures of cardiorespiratory fitness - 35% greater endurance performance with significant improvements to lipid profiles – total cholesterol decreases of 5 to 13% and bad LDL cholesterol 12 to 18%. Exercise alone had no effect on blood lipid levels. “Our data suggest that consuming a single serving of Celsius prior to working out may significantly enhance the positive adaptations of exercise on body composition and cardiovascular health and fitness in previously sedentary overweight women greater than exercise alone,” stated Jeffrey R. Stout, Ph.D., who served as the Chief Researcher of the study. He added, “These results are important due to the fact that these positive results were achieved in sedentary overweight women who are considered at risk for cardiovascular and many other diseases.”
Study 6 - 2010
Our latest study showing the improved physiological response to exercise in previously sedentary men.
The sixth study was presented at American College of Nutrition and published in the Journal of Strength and Conditioning Research. This study was conducted at The Human Performance Laboratory of the Department of Health and Exercise Science at the University of Oklahoma, who presented the results of the sixth scientific study of Celsius, showing that drinking Celsius fifteen minutes prior to moderate exercise may stimulate the fat burning mechanism in previously sedentary adult men that begin a moderate exercise regimen. The 10-week study of 37 college-age men consisted of 5 days a week of moderate exercise and compared participants who consumed one single 12 oz can of Celsius 15 minutes prior to moderate exercise, with participants who did moderate exercise only.
The Celsius group on average experienced the following benefits:
• 78% greater fat loss
• 114% greater decrease in percent body fat
• 79% greater endurance performance
• 32% greater resistance to fatigue (increased energy)
• 5.5 lbs of fat loss
Chief Researcher of the study, Jeffrey R. Stout, PhD., stated “What is extremely important is that the significant reduction in body fat we observed does not appear to be the result of any differences or restrictions in diet, but rather it appears to be the result of drinking Celsius. Additionally, Celsius proved to be significantly more effective than exercise alone at improving aerobic fitness, and the ability to delay the onset of fatigue. This research has validated that Celsius enhances the benefits of exercise and helps reduce body fat while building lean muscle, resulting in positive changes to positive changes to body composition.”
About the studies:
Celsius is committed to science and the above studies were conducted by independent laboratories that represent the country’s leading authorities on exercise science. They are part of ongoing research funded by Celsius to ensure the efficacy of our products. These studies pass the standard for independence in that they were reviewed by experts at scientific conferences and published in science journals.
†In a study of 60 healthy college-aged men and women, 100 calories represents the average calories burned over three hours for those participants consuming a single serving of Celsius®. Celsius® alone does not produce weight loss in the absence of a healthy diet and moderate exercise. Loss of fat mass, gain of muscle mass and improved endurance were benefits found for participants consuming a single serving of Celsius everyday and 15 minutes prior to exercise in a study using a 10-week moderate exercise program.
