Sorry to hear you are diabetic, but am glad you are seeing a dietician.
The main things are to watch sugars, which are in the carbs and natural foods we eat.
There are many good books out there, I have "The Complete Food Counter" It gives you information on vertually any and every food, and foods eaten at restaurants/fastfood.

Most doctors and dieticians will tell you to average around 45 carbs per meal. Mine said less in AM and then I could have higher in the PM, but I think with new evidence that eating your larger meals in the morning and less as the day progresses.

Not only do you want to watch your carb intake but you need to get protien and not just empty carbs.
I like cottage cheese because of the low carb count and is high in protien, same with peanut butter.
So say you can have 45 carbs. Really look at your labels. and watch your natural fruits.

For instance 1 (one) fresh medium bananna has 28 carbs and if you have it with cereal like raisin bran has 46 carbs for 1 cup so 1/2 cup would be 23 carbs, then add your milk if you need sugar use a substatute like splenda. Fiber content is a great bonus.

I know this is overwhelming, but just watch your carbs. being aware of them is a first great start.
Cut down on pasta, white rice, sugar, firied foods. I only use extra virgin olive oil.
Cut sugar drinks use something like coke zero or any unsweetened drink. Some people like to drink those sweetened teas..those are so high in carbs and bad for you. (because of the sugars)
Green veggies are great. You do have to watch your intake of corn, peas and carrots (they have natural sugars) I metion this because some people eat a lot of these certain veggies and don't realize them harm.
Hope I was not to confusing, and helped some:)
Good Luck and God Bless

Oh yeah I wanted to warn you about items that say reduced fat or fat free. Don't think they are better for you, it can be a trap. Sometimes the carb count is higher on those than the regular.

Hi Viv, it's me Grannie from the smoking board, watch your Carbs until you can get to the Doc...his nurse should give you a diet plan to follow. You may want to pick up a copy of "The Calorie King" it tells you the calorie, fat and carbohydrate of foods.

I have porridge for my breakfast with some berries for 5 mornings a week I sprinkle splenda over the porridge then I have 2 poached eggs on 2 slices of rye bread toasted twice a week how is that for breakfast ?

watch white breads, pasta, potatoes and rice. keep track of portion controls, learn to read food labels and watch for carb (carbs are sugar) and fats, make sure to get enough protein...get some exercise on a daily schedule and you will do ok.

Sounds like an excellent breakfast!

As everyone else has mentioned it is key to watch portions sizes and to limit carbs, especially simple sugars.

It's also important to time your meals and snacks so that you there's no long intervals between meals. It's key to avoid dips and spikes in your glucose level.

You can't "fix" unhealthy eating and/or exercise habits all at once overnight. My nutritionist used to make weekly contracts with me to make no more than a half dozen SMALL and very specific changes a week. It's important not to think of this as a "diet" - it's a healthy way of life.
Best of luck!
