Hi yes I am a dietitian-and highly do recommend meeting with an RD who specializes in diabetes management
This actually a pretty good starting place. The trick is what a serving size is. For example-general rule of thumb 15 gm carb is 1/2 cup of something or one SMALL piece (Ie-a regular hamburger bun is at least TWO carb servings or 30+ grams of carb). The "wetter" the food the larger the serving-a cup of grapes vs 1/4-1/3 of a banana for same amount of carb.. This is a very very general rule but over the course of a day or even meal the carbs balance out.
Also-corn, potatoes, peas are considered "grains" or starchy vegetables-meaning they have carb content. Things like carrots, tomatoes, lettuce, do not have high carb content (despite what SM "health" experts tell you)-the sweetness of a carrot comes from the beta carotene NOT SUGAR.
I usually recommend picking one meal to start to "clean up"-if breakfast is a pot sized bowl of sugary cereal-let's get to a higher protein, less processed food and lower carb to start here.
For the record I do NOT advocate a super low carb especially for diabetics. Smart carb choices in lower amounts will result in a far healthier diet than "keto" that's filled with "keto" brownies etc. GOOD sources protein and fats are fine.
Oh-and for most people-most have no idea how many calories they drink during the day (not talking alcohol here but that counts too) but sodas, juices, "energy" drinks, specialty coffees, "smoothies" etc-just cutting this down and out can result in significant calorie reduction.
Also=GOOD FOR ANYONE who wants to improve their health-this is a lifelong journey, sometimes the path winds a bit off the "health" track but you can always find your way back if you choose. Choose better for THIS meal, and then the next "this meal". Start with changes you can sustain, smaller changes to build on.
As for exercise-yes regular activity is important-start with small things again-park the car at the furthest spot from door when shopping. set a timer for 5 minutes every hour you get up and move. Take the stairs (even if you only manage one flight at first). Find a group to walk with that will hold each other accountable. I found a youtube yoga class that I love-she does 10,15, 30, 60 minute classes for all levels-I LOVE her 10 minute beginner wake up yoga-and this does make a difference!
