Cholorophyll is a photoreceptor which is known for its contribution to the green pigmentation in plants. As such, it is found in green leafy vegetables, algae, wheat grass and herbs. This is the only proven connection between chlorophyll and weight loss in that the consumption of these whole foods will aid weight loss as they are rich in fiber and can increase metabolism. The consumption of chlorophyll in liquid form or as a supplement has not been proven to benefit those who wish to lose weight.

The use of chlorophyll as a supplement has been used to aid such conditions as bad breath and other body odors and more recently, to remove toxins from the liver. Some studies have indicated that chlorophyll supplements may reduce damage caused by radiation and chemical carcinogens. However, there is no evidence to support claims that supplements containing chlorophyll and weight loss are connected.

On the other hand, eating whole foods containing chlorophyll will benefit general health and may lead to a gradual weight loss if green vegetables are a part of a healthy eating plan. Spinach, parsley, beans and arugula are examples of vegetables which are high in dietary fiber. The consumption of foods high in fiber aids in curbing the appetite. It is also essential for ridding the body of toxins through waste removal and the enzymes contained in chlorophyll-rich foods help break down the fat molecules. When consumed as a whole food, there is a very positive relationship between chlorophyll and weight loss.

Liquid chlorophyll is a powerful antioxidant and it is claimed that it can reduce the risk of certain types of cancer as well as reduce inflammation. It is also claimed to increase the function of red blood cells which results in better transportation of oxygen around the body. These benefits would actually be better derived from whole foods which would also supply the body with the necessary fiber. As supplements are more concentrated, there can be some side effects such as stomach cramps, nausea, and diarrhea.

The current fashion for drinking liquid chlorophyll in the belief that it will aid weight loss may actually be harmful rather than beneficial. The plants used in the production of liquid chlorophyll may contain pesticides, heavy metals and other toxins. These elements can cause cancer, damage the nervous system or interrupt hormone function. Consume whole foods containing chlorophyll and weight loss is more likely if a sensible eating plan is followed.
