White bread once in a while ok la.. swap with whole wheat bread. Better eat rice all day rather than white bread.
For snacks, eat dense fibrous fruit for carbs as alternative.
Get some good fats in like nuts for snacks. Some cheese for them gainz.

you need good carbs. it is the excess calories that will make you fat, regardless the type of macro.

by not eating rice, indirectly you are eating at a calorie deficit, hence the weight loss.
