If you see this before you see the nurse, the question to ask her is how many carbohydrates a day are they basing his treatment on. Once you have that the best approach is to break it over 3 meals and 3 snacks
Example:
Breakfast 30 grams
morning snack 15 grams
Lunch 30 grams
afternoon snack 15 grams
dinner 30-45 grams
bedtime snack 15 grams
That would be for around 1200 calories a day with protein, veggies, etc added in so if they aren't doing weight reduction it would be higher, but gives you an idea. This was the plan the nutritionist gave me in 2003 when we laid out a weight loss plan, and when my mom, who had been a really diabetic for years, started to follow it - her levels became relatively steady.
But bottom line is to understand what his health care group has planned. The nice thing about this newer approach is that you can actually balance things a little better with the use of some packaged items - although the low sodium consideration is a bit of a problem there.
GOOD LUCK!
