Is my body really sexy or I'm just being overly self obsessed? Diet suggestions would be really helpful.

I've started gym just 3 weeks ago and I'm not taking any kind of rich protein and vitamins source food. I'm eating 2-3 times a day (normal indian thali). Please suggest me a good beginner diet.
