Diet-induced Obesity: Pathophysiology, Consequences and Target Specific Therapeutic Strategies

Diet has emerged as a pivotal factor in the current time for diet-induced obesity (DIO). A diet overloaded with fats and carbohydrates and unhealthy dietary habits contribute to the development of DIO through several mechanisms. The prominent ones include the transition of normal gut microbiota to obese microbiota, under-expression of AMPK, and abnormally high levels of adipogenesis. DIO is the root of many diseases. The present review deals with various aspects of DIO and its target proteins that can be specifically used for its treatment. Also, the currently available treatment strategies have been explored. It was found that the expression of five proteins, namely, PPARγ, FTO, CDK4, 14-3-3 ζ protein, and Galectin-1, is upregulated in DIO. They can be used as potential targets for drug-designing studies. Thus, with these targets, the treatment strategy for DIO using natural bioactive compounds can be a safer alternative to medications and bariatric surgeries.
