Recently, the initial global review of contemporary medicines for weight loss suggest that the use of this medicines cannot be justified based on current evidences. The researchers found that few herbal and dietary supplements result in marginal weight loss compared to a placebo, they do not benefit the health. They are termed for more research into their long-term safety. The sale of these pills, powders, liquids which contain the plant or animal products have turned into the popularity.
On an annual basis, only about 20 percent of latest products are audited. This is done in order to make sure that they provide evidence to back their claims. In few of the countries, the main need is accept that these supplements contain levels of non-medicinal products.
The review of Erica Bessell , an author from the University of Sydney claims that unlike pharmaceutical drugs, clinical evidence for their safety and effectiveness is not required before they hit the market. She further states, “Our rigorous assessment of the best available evidence finds that there is insufficient evidence to recommend these supplements for weight loss. Even though most supplements appear safe for short-term consumption, they are not going to provide weight loss that is clinically meaningful. ”
In August 2018, the researchers have performed out a systematic review of all randomized trials comparing the effect of herbal supplements to placebos on weight loss. The data is being analyses from the 54 researches done. Notably, these studies involved 4,331 healthy overweight or obese adults aged 16 years or older. The weight loss of about 2.5kg can be considered clinically meaningful.
The herbal supplements that are involved in the analysis are green tea, garcinia cambogia, mangosteen, white kidney bean, ephedra, African mango, yerba mate, veld grape, licorice root and East Indian globe thistle. This analysis found that only one of these, the white kidney bean, results in a statistically, but not clinically, greater weight loss of 1.61kg than the placebo.
