Energy & Fitness
Below, Dr. David Heber answers questions about Herbalife’s Energy & Fitness drinks.
Q: How do Herbalife’s Energy & Fitness drinks promote endurance?
A: The natural caffeine in Herbalife’s Energy & Fitness drinks promotes
the body’s release of fat from its fat cells.* This release of fat spares the
body from using all its carbohydrate stores too rapidly.* The carbohydrates
are stored in the muscles and liver as glycogen. By helping the body use its
carbohydrates more slowly while burning more fat, the caffeine in Liftoff ™
effervescent energy drink increases the amount of time that the body can
sustain intense exercise.*
Q: Professional cyclists and runners sometimes use caffeinated sports drinks
like Liftoff ™ before a race. How does caffeine benefit performance?
A: Caffeine improves performance in prolonged events such as cycling and
running by increasing the amount of fat released by the fat cells to be
burned as energy. In fact, during endurance exercise activities, like
running a marathon, the majority of energy used comes from body fat.
Q: How does N-R-G Nature’s Raw Guarana Tea influence energy?*
A: This natural source of caffeine works to increase mental alertness and
improve overall energy to help get you through the low points of your day.*
Not long ago, the National Academy of Sciences increased its recommendation
for the amount of time that individuals should spend on vigorous exercise
every day from 30 minutes to one hour. Herbalife’s Energy & Fitness drinks
can support your energy levels so you feel like you’re up to exercising
longer and more frequently.*
