Acai berries are most known as a weight loss supplement, although they have a number of other benefits such as reducing the aging process and helping cell recovery. The weight loss properties of acai berry can be largely explained by the increased metabolic rate. It occurs because of the very large amount of antioxidants (substances, which prevent oxidative stress and cell damage) that acts as a therapeutic. It leads to faster fat breakdown, increases energy levels and fights fatigue. Combined, these effects make the process of losing weight faster and easier without any side effects.
