The name alone is a marketing and advertising move.
You may have seen Flush the Fat from several TV ads and colon cleanse infomercials that you know its spiel already. Flush the Fat Internal Flush claims to be able to make a huge difference in your weight after you're through with their product. Indeed, with a name that includes 'fat' and 'flush' in the same sentence, it seems that this is the answer to your weight problems.
However, if you look at the ingredients closely and if you listen to the infomercials, you'd see that most of this colon cleanse and detox weight loss product's ingredients are similar to those found in other brands. At best, what this product has is a more aggressive kind of branding and advertising that it paints itself more than it really is.
This is not to say that the product does not work. It does but honestly, it doesn't really deliver as much as it promises.
