Weight gain comes from eating more calories than you use over time, not from one food. Rice is a normal staple for billions of people.
What matters
Portion size, what shares the plate (dal, vegetables, fish or eggs), and how active you are.
A simple plate
Half vegetables, a quarter rice, a quarter protein. Cooked and cooled rice, brown rice and extra fibre can help you feel full for longer. Values on this site are approximate.
