This one seems contradictory—eating normally (or even more) yet losing weight. But in undiagnosed or uncontrolled diabetes, it happens.
Without enough insulin to move glucose into your cells, your body starts burning fat and muscle for fuel instead. You're essentially starving at the cellular level while food passes through your system.
What to notice: Dropping pounds without trying, especially if you're eating enough. This is more common in type 1 diabetes but can occur in type 2 as well.

What to notice: Fatigue that interferes with daily life. Feeling wiped out after meals. Needing naps despite adequate sleep.
