Hi jenniges,
I think the suggestions that leyhdylan gave you are really good ones with
regards to food choices. If your family doctor is saying, I don't know what
to do about all that, perhaps you need a new doctor who will help you
better.
As you said, you have asthma problem. So it is better to follow these diet tips then you can expect the best result for weight loss.
•Eat lean proteins like fish and avoid red meat as much as possible.
•Make sure your major intake should be fruits and vegetables.
•Eat breakfast of complete carbohydrates and protein to set up your metabolism for the day.
•Between meals snacking is a good habit.
•Stay away from fatty foods and simple sugars.
