I think about you've to eat rice or bread is not difference.
Foods consisting of carbohydrate can be slowly/hard to metabolism on body==
If the metabolism more slowly, it's mean absorbing the compounds will increase in your body.
Some foods like Rice, bread, mealt are consist of carbohydrate.
My advice about weight loss that you will start for low-carb eating.
And doing exercise everyday.Fitness or going for swim ..
The important point that you need to eat right and workout
but' i think you can do it
