Herbal remedies and supplements
Chemists and health food stores have shelves dedicated to weight loss supplements, but just because something is labelled as ‘natural’ doesn’t always mean that it’s safe. Many supplements are of limited effectiveness and some contain ingredients that may be harmful.
Fruit based supplements such as papaya are generally considered to be safe to use, although whether they work is ‘debatable’ according to experts. Garcinia cambogia extract is considered safe but not particularly effective. A 2011 review that looked at 12 studies on garcinia cambogia found that taking it led to a loss of about two pounds over a period of four weeks .
Raspberry Ketones are another popular natural weight loss supplement. Researchers have found no evidence so far that they have any effect on weight in humans, although large doses do seem to lead to weight loss in rats.
Green coffee bean extract does seem to have a modest effect. A review of three separate studies found that people taking it lost 5.4 more pounds than people who took a placebo pill. It’s likely that the effects are due to the caffeine in the supplements.
Although most diet pills you can buy over the counter or online are relatively safe, some supplements can be dangerous.
