Metabolism and Diabetes – How the Body Handles Fuel

Skip a meal and feel foggy an hour later? That's your body's fuel-management system sending an urgent signal. This episode explains what metabolism actually means, how insulin and glucagon work as opposing hormones to keep blood glucose steady, and how type 1 and type 2 diabetes each disrupt that system in genuinely different ways, without blame or oversimplification. This is general science information, not medical advice. You'll come away understanding what glucose does for the body, how insulin and glucagon act like a thermostat for blood sugar, the real biological difference between type 1 and type 2 diabetes, how blood glucose monitoring and insulin therapy actually work today, and why "slow metabolism" is a much more modest effect than popular language suggests.
