One of the best ways to cut fat retention is by eating seaweed. I know that sounds gross. I grew up by the ocean and the thought is a little hard to imagine.
However Annie Chun has a product called Sesame Seaweed Snacks that sells for a less than three dollars that delivers 35% of the daily recommended amount of vitamin a and 8% vitamin c.
Seaweed contains alginate which has been shown to reduce the bodies ability to absorb fat by almost 75%. Sounds good to me and for the price definitely worth a try.
