With your background in zoology and your current Master's in nutrition, you have a strong foundation for a PhD in nutrition.

There are two main types of exams you might consider for PhD programs in India.

• UGC NET (National Eligibility Test): This exam is conducted by the UGC (University Grants Commission) for eligibility as a college or university Assistant Professor. While not strictly a requirement for PhD programs, qualifying UGC NET demonstrates your research potential and makes you eligible for fellowships.

• CSIR-UGC NET: Conducted by the Council of Scientific and Industrial Research (CSIR), this exam is similar to UGC NET but focuses on science streams. Qualifying can make you eligible for research fellowships from CSIR labs.
