Caffeine is the most widely used stimulant in the world. You’d be hard pressed to find an effective weight loss supplement that did not contain this ingredient because it is effective in boosting metabolism. You traditionally consume caffeine in drinks and foods. The most common drinks that contain caffeine are coffee, soft drinks and energy drinks.
There is clinical research support for caffeine’s use in weight loss. Caffeine has been shown to positive effect metabolism, athletic performance, cognitive function and mood.
Metabolism – Caffeine is best consumed with green tea extract for weight loss
Athletic Performance – When taken 60 minutes before exercise, caffeine-containing drinks can boost exercise performance. In clinical studies, users noticed increased time performing resistance exercises with caffeine intake.
Cognitive Function – According to PubMed, a division of the National Institutes of Health, caffeine can improve reasoning skills, concentration and focus.
Mood – Clinical studies into the psychopharmacological effects of caffeine showed improved mood with 100 mg of caffeine intake. The results took between 30 and 60 minutes to peak.
There are some side effects associated with caffeine, but only with excessive intake or extreme sensitivity. If you are sensitive to caffeine you should skip your morning coffee and caffeinated soft drinks when taking a caffeine-laced supplement. Do not exceed the recommended dosage of any supplement that contains caffeine to reduce the chance of negative side effects.
The majority of caffeine users report increased energy, the side effect that dieters are looking for. The increase in metabolism and mood are just a welcomed benefit.
