Weight loss laxatives are a crude method of using laxatives to speed food through the digestive system. This is done with the intent of reducing calorie intake and consequent loss of weight. 

Of all purported weight loss supplements ingredients weight loss laxatives is definitely among the most baseless and uninformed. 

Laxatives are a preparation that could include oils, salts and fibers among other ingredients to encourage bowel movements. They are mainly used to treat constipation. They generally work in three main ways. 

One such a way is softening of stool by adding water and /or fat into the stool. This will increase the bulk of the stool and stimulate expulsion. Alternatively they lubricate the stool by adding fat to easily slide the stool through the intestines. Thirdly they are used to stimulate the colon’s nerve endings to induce expulsion.
