The EFS is most effective when the first pills are before breakfast and before exercising.  This is because our metabolism tends to be slower in the morning. By taking the EFS on an empty stomach half an hour before breakfast, you will give your metabolic rate a moment to speed up, which in turn will help both your fat-burning process as well as keep you feeling full throughout the day. You might need that extra energy kick to run through a challenging workout, and taking the EFS before working out will help you burn more calories along the way this is why we suggest you take your second dose roughly 6 hours after your first.
