**3. Conclusions**

Although there is sufficient evidence on the beneficial effect of flavonoids in relation to the improvement in health status in metabolic diseases such as obesity, where flavonoids contribute to recover the lost balance due to the deregulation of lipogenesis and lipolysis, much remains to be done to clarify aspects such as the adequate concentrations suitable for use in drug design, the interactions between the different compounds present, as well as the modifications in the absorption of them depending on the changes in the health states. It is also necessary to deepen into the reaction mechanisms involved for a better management of these compounds according to each pathology.
