Products that seem too good to be true typically leave me feeling cold, and Celsius is no exception. Hoping to be a super soft drink, the new beverage is being marketed with claims that you can burn 100 calories simply by guzzling one can of the carbonated stuff. The drink apparently boosts your metabolism and causes your body to burn more calories, creating a net-negative-calorie effect.
With enough caffeine to cover about two cups of coffee (one can has 200 milligrams), this beverage is not for the caffeine sensitive. Steve Haley, CEO of Celsius Holdings Inc., defends the product's calorie-burning claims by citing clinical studies paid for by his company and mentions the drink's vitamin components that he says counteract the effect of caffeine on buyers' bones.
There are still many unknowns about the effectiveness of Celsius, and I agree with one nutritionist who commented, "Exercise is a better way to jump-start your metabolism, and it's healthier as well." I prefer to drink metabolism-stimulating green tea for a natural, inexpensive way to benefit my health.
