Shorter duration bonds have less interest rate risk than longer duration bonds. Investors and fund managers that are concerned about interest rates rising will reduce the duration of their portfolio by selling bonds that have higher durations and buying those that have shorter durations. You can buy broadly diversified ones that cover the whole bond market, or just government or corporate bonds. Another way to look at it is, a bond is a loan that has been carved up into smaller pieces that many investors can own — the same way the ownership of a company is carved up into shares. For most investors a diversified bond ETF would be the best choice.
The American Journal of Clinical Nutrition in 2004 published a systematic review of meta-analyses and clinical trials on dietary supplements for weight loss by complementary medicine researchers at the Universities of Exeter and Plymouth. None of the over-the-counter weight loss aids worked, including garcinia cambogia. Late in 2010 the peer-reviewed Journal of Obesity published a meta-analysis of studies testing the garcinia as a weight loss aid.
