How to Use This

Hey, starting carb counting feels tricky at first.

Pick your food, set portions, add your personal ratios from your doctor. Hit calculate to see carbs and insulin needs right away. Test blood sugar before and after meals to fine-tune.

What if my meal mixes foods?

Run each item separately or use custom for totals. Factor in fats or proteins slowing carb absorption by checking sugar 2 hours later.

Daily Meal Ideas

Need quick 45g carb breakfasts?

Two slices toast (30g) + medium banana (27g). Or oatmeal cup (30g) + milk (12g). Pair with protein like eggs to steady sugar rise.

Lunch under 60g?

Half cup rice (22g) + chicken salad + apple (25g). Watch dressings adding hidden carbs.

Dinner balance?

Medium potato (26g) + beans half cup (20g) + veggies. Lean meat keeps it steady.

Type 2 needs this?
