When insulin levels drop too low, the body can no longer efficiently move glucose from the bloodstream into cells for energy. As a result, it switches to burning fat instead.

This can happen in a few situations for people with diabetes:

- Not enough insulin – Without sufficient insulin, cells can't absorb glucose, so the body looks for another fuel source.
- Fasting or skipping meals – Going long periods without eating can trigger this switch.
- Poor blood sugar management – Persistently high blood sugar combined with low insulin availability can push the body toward fat burning. Burning fat for energy is a slower process than using glucose, which is why it can leave you feeling more fatigued. It also produces by-products called ketones.

If ketones build up too much in the bloodstream, it can lead to a serious condition called diabetic ketoacidosis (DKA). Symptoms of DKA include vomiting, stomach pain, confusion, and shortness of breath — and it requires immediate medical attention.

Keeping insulin levels properly managed is the key to helping the body use glucose efficiently as its primary fuel source.
