One of the major ways caffeine boosts fat loss is through its ability to bind to fat cells and enhance the removal of fat from them while inhibiting the storage of more fat. Caffeine also works to increase fat-burning during rest and exercise.

Green tea extract contains compounds known as catechins. One of them, called epigallocatechin gallate (EGCG), is responsible for the majority of green tea’s fat-burning effects. EGCG has the ability to inhibit an enzyme that breaks down norepinephrine, the neurotransmitter involved in regulating metabolic rate and fat-burning. By stopping the breakdown of norepinephrine, you can keep metabolism and fat-burning elevated for longer, especially when caffeine is used to free up fat from fat cells. Research studies confirm that green tea extract can significantly boost fat loss.

Combine them like this: Go with 200 to 400 mg of caffeine anhydrous with 500 to 1,000 mg of green tea extract standardized for EGCG in the morning and an hour before workouts. On rest days, take a second dose in the afternoon.
