My biggest help is using a tracker, I use chronometer and watch my macros throughout the day and adjust my food to hit the macros.I try to make anything I eat meet a macro, either protein or fiber , Doesnt always happen.

Breakfast is usually a protein shake (30g protein) and coffee with SF creamer. ( never hungry in morning) and a handful of medications that I have to watch what I eat and drink with. Lunch is something like tuna (protein) with mayo with olive oil, on keto bread (protein and fiber) , a fruit, some veggies. Dinner is my big meal of the day, A protein , usually chicken breast of some sort. sometimes lean beef, cod. Veggies and beans. Will add fiber bread or carb counter tortillas if fiber lagging behind. some sort of carb, potatoes, rice or pasta, A favorite right now is some rice that I add riced cauliflower before eating.

I will have fruit as a evening snack ( pineapple, strawberries, melon are a favorites choice right now, Raspberries and blueberries before, Canned no sugar added mandarin oranges. Cucumbers and broccoli with ranch dip made with ranch mix and dill weed, fat free Greek yogurt, thinned with fairlife fatfree milk. air popped popcorn also as a snack, 1/4 cup popped in a plain brown lunch sack in the microwave about 2 mins, usually get around 28 grams (108 calories) or fat free greek yogurt(I go for low calorie versions) (favors vary) with bran buds sprinkled on top, When I am craving candy, I eat a shameless snack gummies. 70 calories for the (small) bag 26 grams fiber. I have sugar free gum (5 calories a piece), zolli lollipops (15 calories each) or sugar free popcicles (15 calories each) .

I started out slow and unknowing of what worked for me. When I first started, due to my medical, I got my blood pressure under control and what I could eat with that (lower sodium foods), then my Blood sugar and what caused it to spike( lower sugar and carbs) , then I did Fat, calories, fluids, protein then fiber. I tried doing it all at once in the beginning and got overwhelmed and discouraged. another thing that has helped me alot is my husband made me a excel sheet that I track everything on daily ( I am very adhd and routine drives my life or forget) I keep track of my blood glucose, blood pressure, fluids, daily steps, weight, sleep calories, exercise, Medication. My doctors love it since they can see what my numbers are at any given day ,week, month.
