Can your body live without sugar?

Yes, your body can survive and even thrive without added sugars, as it can create its own necessary fuel (glucose) from complex carbohydrates, proteins, and fats, but it needs some form of sugar (glucose) to function, primarily for the brain, which it can get from whole foods like fruits and vegetables. Going without added sugar is possible and beneficial, leading to better energy and clarity, but it's about balance, not necessarily complete elimination of all sugar (including natural sugars).
