Hidden potential of tropical fruit waste components as a useful source of remedy for obesity.

The array of comorbidities that comes with obesity and the propelling surge of this disease globally today make the urgent need for treatment vital. Although promoting a healthy physical regimen and controlled diet to affected patients are the main bulk of present treatment, prescriptions of weight-loss medications have also been introduced to complement this treatment. However, the use of synthetic medications may produce adverse side effects and consequently affect the patient's quality of life. In view of these problems, the use of natural sources as alternative remedies has recently become very popular. Tropical fruit "waste components", namely, the seed, flower, leaf, peel, and part of the fruit, which are often discarded after consumption, have recently been studied and showed evidence suggesting their potential as promising future alternative sources of remedy. The high amounts of phytochemicals present in these components were believed to be responsible for the antiobesity effect observed experimentally. This review aims to introduce some of the recently discussed tropical fruit waste components that have been discovered to possess antiobesity effects. The major bioactive compounds of the respective fruit components identified and deduced to be responsible for the overall bioactivity will be evaluated. Following this, the subsequent need for the development of an effective processing or recycling technique required to effectively tap the maximum potential of these fruit parts will also be addressed.
