Can a diabetic go all day without eating?

No, a diabetic generally should not go all day without eating, as it's very risky and can cause dangerous hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), especially if taking insulin or other medications, and can lead to dehydration or even Diabetic Ketoacidosis (DKA) in Type 1 diabetes, requiring close medical supervision and adjustments to medication. Always consult your healthcare team before attempting fasting, as they'll help you safely manage medication, fluids, and blood sugar levels.
