Some people assume that products labeled natural are safe. The U.S. Department of Health and Human Services, however, reports that natural weight loss products are not all safe. In the past, herbal products containing ephedra caused health problems for some users, even leading to death. Rather than risk health complications, people should discuss the safety of natural weight loss products with a doctor before using them.
Weight Loss Teas
Weight loss teas may help dieters fulfill their hydration requirements and lose slightly more weight than with dieting alone. Green tea is touted for its purported ability to increase the metabolism. The chemical epigallocatechin gallate, EGCG, is thought to be responsible for these effects. According to the American Journal of Clinical Nutrition, green tea promotes fat oxidation. Other weight loss teas have natural ingredients that promote bowel movements and claim to detoxify for greater results.
Herbal Supplements
Although herbal supplements are not magic bullets for weight loss, some have a stimulant effect that gives dieters an edge. However, risks often exist with these supplements. MayoClinic.com reports that certain chemicals in bitter orange capsules---syneprhine and octopamine---are similar to those in epehdra and may therefore have similar negative effects like increased heart rate and blood pressure.
Apple Cider Vinegar
Sometimes marketed as a fat-burner and appetite suppressant, apple cider vinegar--a light brown liquid--is a natural product derived from fermenting apple juice. Other versions of the product are available in tablet form. Rumors of the products effectiveness at burning fat may have been sparked after a popular book: "Folk Medicine: A Vermont Doctor's Guide to Good Health," written by D.C. Jarvis, M.D., was published in 1958. Research proving the product's efficacy is lacking, however. MayoClinic.com reports that, due to the highly acidic nature of apple cider vinegar, it may cause throat irritation with repeated use. It may also interact with some medications or supplements.
