My first hesitation came when I received an information package from a colleague that has become a Body By Vi promoter. It was this table which compared Body By Vi to some of the other drink supplements/meal replacement beverages that are out there. I was instantly appalled when I noticed that the Body By Vi nutrition information was listed in it's powdered form and being compared to products that have already been mixed (usually with a dairy product). This instantly made the Body By Vi look lower in calories and fat. Totally misleading.
Body By Vi also prides itself on using social marketing or what many people refer to as 'The Pyramid Scheme' technique for advertising their product. What that means is there is an incentive for convincing other people to jump on the product wagon. For every two people you convince to buy the product, you get your shakes free for a month. If you sell enough product, you can even win a BMW. What they don't tell you about the BMW is that you have to pay the lease on it and if you don't keep up your sale numbers, they take to car back (unless you want to buy the car back from them).
Their clinical research is also questionable. I haven't been able to find it since, but a fellow Registered Dietitian had found one of their websites that linked to their 'white papers' (their term for clinical research papers) that were the evidence for their product's effectiveness. Based on her review, the papers don't hold up much. The studies were poorly designed, biased (one of the lead researchers is from the Body By Vi Board) and some of the papers didn't even have anything to do with weight loss (some were on hearing loss).
All I'm suggesting is that you take this product with a grain of salt (well not an actual grain of salt). Between its lack of balanced nutrition and questionable marketing tactics this product gets a big thumbs down from this dietitian.
