What Really Happens When Blood Sugar Spikes — And Why It Matters

When you eat — especially foods high in refined carbs or sugar — your body breaks them down into glucose, which enters your bloodstream.

A blood sugar spike happens when glucose levels rise quickly after eating. In response, your pancreas releases insulin to move that sugar into your cells for energy or storage.

The problem? Repeated spikes can lead to insulin resistance, where your body stops responding effectively to insulin. This can push you toward pre-diabetes and type 2 diabetes.

You don’t need to cut out all carbs to prevent spikes — but choosing high-fibre foods, pairing carbs with protein or healthy fats, and moving after meals can make a big difference.

Understanding your body’s response is the first step toward balanced energy, reduced cravings, and better long-term health.
