has anyone ever done a liver cleanse?

im by no means a medical professional, but i do research extensively into things im interested in, from what i know regarding the liver, because it processes and filters the blood constantly, it is a very susceptable to biological "sludge" build up, this can interfere with your liver's natural fat processing and metaboliszing capabilities, a sluggish liver may compromise your weight loss efforts simply from being clogged by fat cells, especially when you are an overweight person. Thus, it is beleived that by cleansing the liver, evacuating the years of build up debris and other harmful things found in our blood, our livers will function more efficiently, processing and metabolizing fat quicker/better. The cleanse is nothing synthetic, i have read many variations of a liver cleanse, some including castor oil and lemon water for a certain amount of time, others are more realistic and less dramatic, such as what im doing, im simply eating raw vegetables and fruit, (sometimes in smoothie form) with 3 litres of water daily for three days, the idea is to give your liver a rest, im not interested in going more extreme than that for a cleanse especially when the theory is not universally supported
