Well - this probably fits with the "guidelines" the doctor gave:
1) High carb and low (30g or less per day) fat diet is usually the norm. Carbohydrates give energy. They're present in foods made from starches (complex carbohydrates) or sugars (simple carbohydrates). She should try to get most of her daily calories from complex carbohydrates found in fruits, grains, vegetables and legumes. If the diet guidelines the doctor gave do not include the amount of fat that is permissable - ASK HIM/HER how much fat to eat each day because some fat is essential! So, some lean protein would not be ruled out - but whole milk, butter, cheese probably would.
2) Eat more and smaller meals. The more you eat during a meal, the greater the amount of digestive juices your pancreas must produce. Instead of large meals, eat smaller, more frequent meals.
3) No alcohol or caffine (coffee, tea or cola drinks)
4) No nicotine - no smoking, dippin' or chewin'
You know what dietary guidelines the doctor gave - you'll just have to look for some recipes that fit those guidelines. But, basically, don't worry about carbs - just look for ways to reduce the fat in her diet.
Most doctors don't have a dietician or nutritionist on staff in their office (I've only know one - and she was his wife) ... so you might try calling your local hospital and asking to speak to the head dietician. Or - you can just "wing it" and do a Google search on low-fat recipes and see what you can come up with ... there's a bunch I am sure.
