FASCINATING! To prevent diabetes, you don't actually have to change what you eat tonight. Just the order in which you do so.
Researchers at Kyoto University published a study this week in the journal Diabetes showing that taking a small amount of olive oil before eating carbohydrates, rather than during or after the meal, significantly reduced the early blood sugar spike that follows a carb-heavy meal. Even in mice with type 2 diabetes and severe insulin deficiency, olive oil taken first still blunted the blood sugar rise. The mechanism turned out to be more interesting than anyone expected, and the practical takeaway takes about 30 seconds to act on.
What the science actually shows
When olive oil reached the gut before carbohydrates, it triggered an early release of two hormones, glucagon and GLP-1, working together with the vagal nerve to slow gastric emptying. In plain terms: the stomach held onto its contents longer, which meant glucose entered the bloodstream more gradually rather than flooding in all at once. Mice that got oil first had significantly lower blood sugar 15 and 30 minutes after eating compared to those who got oil during or after the meal. The timing was the entire variable. Same food, same amount, completely different metabolic response based on what came first. The researchers specifically noted that this builds on existing clinical evidence suggesting that eating vegetables, protein, or fat before carbohydrates produces smaller blood sugar spikes, and that their study now provides a clear biological explanation for why the order matters.
Why blood sugar spikes matter for everyone, not just diabetics
Most people think about blood sugar as a diabetes concern. It isn't, or at least it shouldn't only be. Post-meal blood sugar spikes affect energy, hunger, mood, inflammatory markers, and over time contribute to insulin resistance that sets the stage for metabolic disease, weight gain, and cardiovascular risk years before a diabetes diagnosis ever comes. The afternoon energy crash most people experience after a carb-heavy lunch is largely a blood sugar spike and subsequent drop playing out in real time. Managing those spikes through how and what you eat is one of the most accessible metabolic health tools available, and this research adds a specific, practical piece to that picture. A tablespoon of olive oil or a handful of nuts before your bread, pasta, or rice changes what that meal does to your blood sugar in a measurable way.
What to actually do with this
The olive oil timing finding adds to a body of evidence around meal sequencing that is genuinely useful and costs nothing to implement. Eat your salad, vegetables, or a small amount of healthy fat first. Then your protein. Then your carbohydrates. A drizzle of olive oil on vegetables before the pasta arrives, a few bites of avocado before the rice, a small handful of almonds before the sandwich. None of this requires overhauling your diet, buying a supplement, or tracking anything. It is a sequencing strategy that takes seconds to implement and has a measurable effect on your metabolic response to every meal you eat for the rest of your life. For anyone on a GLP-1 medication, it works with the same hormonal pathway the medication targets, which means it amplifies rather than duplicates what the medication is already doing.
One small habit. Every meal. Every day. That compounds into something significant.

MyCare Clinic Pro Tip: If you are on a GLP-1 medication and still experiencing energy dips or hunger between doses, meal sequencing and the composition of what you eat before carbohydrates can make a meaningful difference to how steady your blood sugar stays through the day. Worth trying before adjusting your dose.
