Wendy Bumgardner is a certified marathon coach (RRCA) and an avid walker who keeps abreast of the latest research and information on walking for weight loss, fitness and sport. Her theory is that by replacing one 1.5 mile drive each day with a walk to and from a local destination, you can save the planet and lose weight.
Wendy recently reviewed popular diet energy drinks for Walking.About.com. Of the five most popular brands that she selected to review, one other had an enjoyable taste and gave her a ”temporary energy boost” but Celsius topped the list.
A couple of my walking buddies like having a Red Bull energy drink as they get near the end of a long endurance walk. But these expensive drinks aren't designed for endurance sports. For one thing, they are carbonated, so you can't pack them with you without causing a geyser when you open them. Instead, most are meant to appeal to youth to give a burst of energy from caffeine and caffeine-like substances. But I was tempted to try the diet versions – not when walking, but when facing a mind-numbing afternoon at work. My taste test definitely produced winners and spit-out losers.
Celsius touts itself as a negative-calorie drink. They have a MetaPlus blend of metabolism-boosters that include green tea extract, ginger extract, caffeine, gurana, B-vitamins, biotin, Vitamin C, calcium and chromium. What they don't have is sugar, aspartame, high fructose corn syrup, artificial colors, artificial flavors, or artificial preservatives. They have a variety of sparkling flavors and are about 10 calories per can. I didn't mind the cola flavor, but the other flavors had that off-taste you get with these energy drinks. Yes, I could feel the energy boost, which is the caffeine equivalent of two cups of coffee.
