Fitness From the Ground Up: Expert answers to your health and wellness questions
Question: There are so many fat-burning products on the market -are they helpful or harmful?
Answer: There are numerous products on the market that contain thermogenic ingredients, or what most of us call “fat burners.” Ephedrine, yohimbine, green tea extract (EGCG), bitter orange (Synephrine) and even caffeine are examples and they basically work by stimulating the central nervous system.
This increases your “fight or flight” responses, indirectly providing energy and allowing you to process calories at a faster rate. Along with these supposed benefits, there are also side effects associated with these ingredients, including increased blood pressure, heart rate and respiratory rate. Another potential issue is the fact that, individually, they don’t have a real dramatic effect.
