Why You Crave Sugar (And What It Means for Your Health)

Have you ever wondered why you crave sugar even when your blood sugar is already high? It happens more often than most people realize, and it usually comes down to what your insulin is (or isn’t) doing.

The Patient Who Couldn’t Shake His Cravings

A patient came into the clinic recently, worried about his hemoglobin A1c, which is a long-term measure of blood sugar. His numbers were double what they should have been. He was eating well, doing what he thought was right, yet the cravings would not let up; he felt stuck.

“I want patients to understand that a sugar craving isn’t a lack of willpower. It’s your body telling you it can’t get fuel into the cells the way it needs to, and once you fix that, the cravings quiet down on their own.” Dr. Dan Timmerman

What Insulin is Actually Supposed to Do

Here is the part that surprised him: when your reading is high, that sugar is sitting in the bloodstream, not inside your cells, where it can actually be used for energy. Insulin is the hormone that unlocks the door and lets sugar move from the blood into the cell. When that process works well, your body gets the fuel it needs, and the cravings settle down.

When Insulin Resistance Takes Over

Insulin resistance is what happens when that door stops opening properly. The receptors get overwhelmed from too much sugar and too much insulin, so they start tuning it out (a bit like a parent who has heard one too many requests and just needs a quiet weekend to reset). The cells stay hungry, the brain keeps signalling for more sugar, and the cycle continues.

Three Small Habits That Make a Real Difference

The good news is that a few small, consistent habits can start to turn this around. Aim for roughly 30 to 40 grams of protein at each meal; protein slows the glucose spike and keeps you from crashing an hour or two later. Try a short walk after eating, since muscle contraction pulls glucose into the cells without relying so heavily on insulin. And consider a gentle intermittent fasting window, starting with 12 to 14 hours overnight, to give those insulin receptors a chance to recover.

Why This Matters Beyond Your Blood Sugar Number

This is not just about avoiding a diabetes diagnosis or a prescription. Chronically high blood sugar and insulin drive systemic inflammation, which shows up as joint pain, faster aging, and, yes, changes we can actually see on spinal x-rays. As a Winnipeg Chiropractor, Dr. Dan sees patients in their thirties whose spines look twenty years older on imaging, and inflammation is often part of that story.
