Frequently Asked Questions
:question: Does toasting bread reduce calories?
Toasting removes water, concentrating calories per gram. However, it may lower glycemic impact by altering starch structure.
:question: How many white bread slices per day are safe?
Diabetics: ≤1 slice (15g net carbs)
Weight loss: ≤2 slices (154 kcal)
Active adults: ≤4 slices (with protein/fiber)
:question: Why does gluten-free bread have more calories?
Rice/potato starch replacements are calorie-dense and lack fiber. Always check labels.
