I agree that a meter is a good thing. How am I doing ? A meter tells you how you are doing.
Here is a list of some of the dangerous things to eat.
Chicken is great, but when they put breading on it, the breading itself is a carb. We count the carbs by estimating the amount of the breading.
French fries are delicious, but we try to eat small portions of them, because potatoes are carbs. If I eat some fries, I do not eat the hamburger bun, rather I eat the burger and it's accoutrements with a knife and fork. Put the bread on your napkin.
Shrimp are fun, but when they dip it in batter, we have to count the carbs in the batter. And sauces in restaurants are full of sugar. Be careful.
Cokes and Pepsis have loads of sugar in them. Stick to the diet versions of those drinks.
A sandwich for lunch is almost always accompanied by potato chips. Either eat the bread or eat the chips. Do not eat both. A lot of the time, it is a compromise.
Some people use Campbell soups as a base for casseroles or pot pies. The label on the back is for one serving. There are 2.5 serving per can. All those soups have a lot of carbs.
Pancakes are bread. They are full of carbs. The maple syrup is full of sugar. I'm sorry that I have to be the one to tell you to avoid these dangerous foods.
Pumpkin pie is the worst. The crust is full of carbs and the sweet potato is full of carbs. Cakes and pies and pastries are danger traps.
Apples are great, but an apple pie has added sugar. Peaches are delicious, but cobblers have sugar added. Oatmeal with mulled cherries and cream are delicious, but we must count the carbs in the oats and the sugar in the cherries. Small portions may be the idea here.
Mexican restaurants are difficult. Chips and flour tortillas and beans and rice. We have to count all these carbs, because our numbers (the amount of glucose in our blood) skyrockets in a Mexican restaurant.
Don't be afraid to eat. Just eat intelligently. It is an adventure. We are pulling for you.
