Blood sugar control isn’t just important for people with diabetes—it’s also key for heart health, energy levels, and preventing chronic diseases. But even if you eat well most of the time and steer clear of added sugar, some of your daily habits could be sabotaging your blood sugar without you even realizing it.
Here are eight sneaky habits that could be raising your blood sugar and what to do instead.
1. Starting Your Day with a Sugary Drink
That morning latte or energy drink might give you a quick boost, but it could also send your blood sugar soaring thanks to high amounts of added sugar.
For example:
• A grande White Chocolate Mocha from Starbucks has 46 grams (about 11.5 teaspoons) of added sugar.
• A 16-ounce Rockstar energy drink packs in 61 grams—nearly 15 teaspoons.
These drinks lack fiber and protein, which help stabilize blood sugar, and drinking them on an empty stomach can make the spike worse.
Tip: If you can’t give up your sweet morning drink, try cutting back on added sugars or pairing it with a high-fiber, high-protein breakfast.
2. Not Drinking Enough Water
Dehydration can raise your blood sugar. Low water intake increases hormones like vasopressin and cortisol, which affect blood sugar regulation.
Studies show that drinking more water can help reduce your risk of developing type 2 diabetes.
Tip: Sip water throughout the day—not just when you’re thirsty.
3. Constant Stress
Stress triggers the release of adrenaline and cortisol, which can cause your blood sugar to rise. Chronic stress can also make you feel hungrier and crave sugary foods.
Tip: Manage stress with calming activities like walking, meditation, or journaling.
4. Not Getting Enough Sleep
Poor sleep impacts blood sugar control. Research shows that sleep deprivation increases blood sugar swings and makes you crave sweets.
Tip: Aim for at least 7 hours of sleep each night. If you struggle with sleep, talk to a doctor or sleep specialist.
5. Sipping Sugary Drinks All Day
It’s not just your morning coffee—sodas, chocolate milk, and juice throughout the day can keep blood sugar levels elevated.
Regularly consuming sugary drinks is linked to a higher risk of type 2 diabetes and metabolic syndrome.
Tip: Limit sugary drinks and stick to water, unsweetened tea, or sparkling water most of the time.
6. Skimping on Protein and Fiber
Protein and fiber slow down digestion and help prevent blood sugar spikes after meals.
Think meal timing doesn’t matter? A 2020 study found that people with type 2 diabetes who ate protein and veggies before carbs had 40% lower post-meal blood sugar levels than those who ate carbs first.
Tip: Add protein (like chicken, eggs, or tofu) and fiber (like veggies or whole grains) to every meal or snack.
7. Sitting Too Much
Being sedentary increases the risk of health issues, including type 2 diabetes. But even short bursts of movement—like a 10-minute walk after dinner—can help manage blood sugar.
Tip: The CDC recommends 150 minutes of moderate-intensity exercise per week (or 75 minutes of vigorous activity), plus strength training at least two days a week.
8. Relying on Takeout and Fast Food
Fast food is often loaded with refined carbs, unhealthy fats, and excess calories—all of which can spike your blood sugar.
Studies show that cooking at home more often is linked to a lower risk of obesity and type 2 diabetes.
Tip: You don’t have to give up your favorite restaurants completely, but try cooking more meals at home using blood sugar-friendly ingredients like lean protein, healthy fats, and high-fiber carbs.
What to Do If Your Blood Sugar is High
If you suspect your blood sugar might be high, make an appointment with your healthcare provider. They can do a blood test to check your levels and offer personalized guidance.
If your blood sugar is elevated, they may recommend a plan that includes:
• Cutting back on added sugars and refined carbs
• Increasing physical activity
• Managing stress
• Improving sleep habits
Seemingly harmless habits—like skipping water, skipping workouts, or sipping a sugary latte—can have a bigger impact on your blood sugar than you might think.
But with a few simple changes, you can better balance your blood sugar and reduce your risk of diabetes and other health conditions.
