Raspberry ketones and Hoodia have not yet benefited from human clinical studies, but both already have a history of use. Raspberry ketones affect the body’s metabolism by raising the core body temperature, and enhancing the breakdown of the body’s native fat deposits.
Raspberry ketones encourage movement and exercise by virtue of higher body temperature, and then allow for the efficient breakdown of fats as the body’s energy source.

Hoodia is a supplement that comes from a flowering plant native to Africa. It has long been used by bushmen as an appetite suppressant, providing them with energy for long hunting trips without them needing to consume food or water. However, Hoodia is also under threat of extinction due to overuse and over-export.
Raspberry ketones and Hoodia work differently, and are therefore difficult to compare in terms of their ability to encourage weight loss. When placed in the same weight loss supplement, however, raspberry ketones and Hoodia could work well together. Hoodia could prevent you from overeating, while raspberry ketones could encourage your body to use its existing fat stores as a source of energy."
