Testing before then 2 hrs after every meal will help you decide how many carbs to eat without spiking your blood sugar too much.
I spent time thinking about the foods I'd miss the most and found low-carb substitutes for them, ce[ebrated the foods I'd been told to avoid which are good for me (cheese, eggs, olive oil dressings, etc.) and investigated foods I'd never eaten before.
I checked the carbs in everything!
It was hard work at first but now I rarely need to weigh anything apart from low-carb cake recipes.
