The stimulatory effects of sfRB on REE are mimicked by water + caffeine, indicating that the auxiliary ingredients do not influence this thermic effect. SfRB enhanced thermogenesis and marginally shifted RQ to favor carbohydrate oxidation. Water + caffeine had no effect on RQ relative to water + placebo. SfRB and water + caffeine both increased REE to the same degree (+4%). This amount of caffeine is roughly equivalent to the amount found in a typical cup of coffee, which contains around 95 mg of caffeine. Nutrition facts label and information for Energy drink, RED BULL, sugar free, with added caffeine, niacin, pantothenic acid, vitamins B6 and B12 - Per 100. For a brief background, calories are the amount of energy you get from consuming food or beverage. Nutrition Facts of Bang right off the packaging. REE and respiratory quotient (RQ) were measured in eight healthy young men by ventilated-hood indirect calorimetry for 30 min baseline and 2 h following ingestion of 355 ml of either: sfRB + placebo, water + 120 mg caffeine, or water + placebo, according to a randomized cross-over design. Red Bull Sugar Free is a popular energy drink that contains 80 mg of caffeine per 8.4 fl oz can. Just to highlight some details, Bang has zero-calories, zero-sugar, and zero-fat, while Red Bull contains 110 calories, 27 grams of sugar, and 28 grams of carbohydrates. Therefore, the metabolic impact of sugar-free Red Bull (sfRB) to a comparable amount of caffeine was compared. The sugar content in this product is zero. Despite not providing sugar, sugar-free Red Bull may still increase your risk of type 2 diabetes if consumed regularly, as it contains two artificial sweeteners aspartame and acesulfame K. They consumed it from natural sources like tea, coffee, cacao beans and cola nuts and appreciated its stimulating effects. One serving (250ml) of Red Bull Sugar Free provides 10 calories, 80mg of caffeine, and 27g of total carbohydrates. Sugar-free Red Bull is lower in calories and sugar but has the same amount of caffeine as regular Red Bull and therefore likely the same potential side effects. Yet little is known about the acute influence of these drinks, and specifically the role of the cocktail of non-caffeine ingredients, on resting energy expenditure (REE) and substrate oxidation. Caffeine was well known by ancient civilisations. By virtue of their bioactive ingredients (including caffeine, taurine, glucuronolactone, and B-group vitamins) and paucity of calories, sugar-free 'diet' versions of these drinks could be a useful aid for weight maintenance. Consumption of energy drinks is increasing amongst athletes and the general public.
