Jerry had been using several weight loss supplements that were starting to lose their power and punch for him. It was as if these supplements were losing their effectiveness, due to him becoming immune to their results. This was probably because they were made up of mostly synthetic ingredients, and so Jerry purchased the acai berry diet, to see if it would do a better job for him. He was actually astounded at the difference the berries of acai made in his weight loss and health supplementation program. He now swears by the natural and empowering effects of the tiny berry of acai from South America.
