I was 73, with a heart condition, beer gut, and overweight. I watch Dr. Gundry's video when he first introduced his Prebiotic product and while watching, the light came on because he made sense in a way that helped me understand what was wrong with my gut. So, tried the powder 30-day supply, lost weight, and gut in the first 3 weeks, never did finish the supply, but continued to lose weight and gut. Short story, went from 192 lbs and a 38 waist to 160 and a 32 waist in 4 months, once my system was corrected with the product. Did not alter my diet, but did eliminate foods he suggested.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
