Thanks for your advice Squire and Dawn. I have been eating a fair amount of white rice (normally twice a day) so I will reduce the quantities and try to convert to brown rice. I will also cut out the sugary snacks. I don't eat potatoes and I have only one slice of brown bread each day.
I don't want to lose weight, so I guess I should increase my intake of other foods such as meat, fish, eggs, nuts, etc, as per the low carb or paleo diets. Would these be the right foods to eat to maintain my weight?
Sorry if it seems a silly question. This is all a bit new to me.
