If your blood sugar has been creeping higher, you may think you need to completely change your life. You probably don’t.
Some of the most effective ways to improve blood sugar are surprisingly simple. A short walk after dinner. Lifting weights a couple of times a week. Eating more fiber. Getting enough sleep.
None of these is a magic cure. But when you put several of them together and practice them consistently, they can make a meaningful difference.
Here are seven habits worth working on.
1. Move After You Eat
One of my favorite blood sugar habits is also one of the easiest: Take a 10-minute walk after a meal.
When you eat carbohydrates, they are broken down into glucose, which enters your bloodstream. Your body releases insulin to help move that glucose out of the blood and into your cells.
But something interesting happens when you start moving. Your working muscles can take up more glucose from the bloodstream. That means a little activity after eating can help reduce the rise in blood sugar that normally occurs after a meal.
You don’t have to walk fast. Walk around your neighborhood. Walk through the grocery store. Walk your dog. If the weather is bad, walk around your house. Even breaking up long periods of sitting with a few minutes of movement can help.
Try this: Start with a 10-minute walk after your largest meal.
2. Give Your Muscles a Reason to Stay Strong
Muscle isn’t just important for helping you lift groceries or get out of a chair. It is also one of your body’s most important places for handling glucose.
Think of your muscles as a large storage and work site for glucose. When you use your muscles regularly, they become better at taking glucose from your bloodstream and using it for energy.
Unfortunately, we tend to lose muscle as we get older, especially if we aren’t doing resistance exercise.
That’s one reason I recommend strength training as we age.
You don’t need to become a bodybuilder. Resistance bands, dumbbells, weight machines, or body-weight exercises can all work. Exercises such as squats to a chair, wall push-ups, rows, and resistance-band exercises are good places to start.
For many adults, resistance exercise two or more days each week is a reasonable goal.
3. Eat More Fiber
Fiber is one of the most underappreciated tools for metabolic health.
Unlike many other carbohydrates, fiber isn’t rapidly broken down into glucose. Fiber-rich foods can slow digestion and help reduce rapid rises in blood sugar after meals.
Good sources include:
- Vegetables
- Beans and lentils
- Berries and other whole fruits
- Oatmeal and other whole grains
- Nuts and seeds
Fiber also helps you feel full, supports healthy digestion, and may help with cholesterol.
Instead of obsessing over eliminating carbohydrates, start by improving the quality of the carbohydrates you eat. An apple and a glass of apple juice both come from apples. But your body doesn’t necessarily handle them the same way. The whole apple gives you fiber and takes longer to eat and digest.
4. Include Protein With Your Meals
Protein is especially important as we get older because it helps us maintain muscle. And remember: muscle helps manage glucose.
Protein can also make meals more satisfying and may help reduce the temptation to snack on highly refined carbohydrates later.
Good choices include fish, poultry, eggs, Greek yogurt, cottage cheese, beans, lentils, tofu, and other minimally processed protein foods.
Try building meals around a simple formula: Protein + vegetables or fruit + a high-fiber carbohydrate.
Breakfast might be Greek yogurt, berries, and nuts.
Lunch might be chicken, vegetables, and beans.
Dinner could be fish, roasted vegetables, and a small serving of brown rice.
It doesn’t have to be complicated.
5. Protect Your Sleep
Sleep probably isn’t the first thing you think about when you think about blood sugar. But it matters.
Poor or insufficient sleep can affect hormones involved in appetite and metabolism and can make the body less responsive to insulin.
It can also make healthy choices harder.
After a terrible night’s sleep, how many people wake up excited to exercise and eat broccoli? Probably not many.
Most adults should aim for roughly seven or more hours of sleep a night, although individual needs vary.
Try keeping a regular bedtime, limiting late-night alcohol, keeping your bedroom cool and dark, and putting electronic devices away before bed.
And if you snore loudly, stop breathing during sleep, or remain unusually sleepy during the day, talk with your healthcare professional about possible sleep apnea.
6. Work Toward a Healthier Weight—If You Need To
Not everyone with elevated blood sugar needs to lose weight.
But for people carrying excess body fat, particularly around the abdomen, modest weight loss can improve insulin sensitivity and blood sugar control.
And you don’t necessarily need a dramatic transformation. Even relatively modest weight loss can produce health benefits in people with overweight or obesity.
Instead of chasing a crash diet, focus on habits you can maintain: Eat mostly minimally processed foods. Watch portion sizes. Get enough protein and fiber. Exercise regularly. And don’t drink many of your calories.
The goal isn’t simply to weigh less. The goal is to improve your health while maintaining as much muscle as possible.
That’s another reason resistance training is so important.
7. Cut Back on Highly Refined Carbohydrates and Sugary Drinks
You don’t need to declare war on carbohydrates. But some carbohydrates are much easier to overconsume than others.
Sugary drinks are a good example. Regular soda, sweet tea, many energy drinks, and some specialty coffee drinks can deliver large amounts of sugar very quickly without making you feel particularly full.
Highly refined foods such as candy, pastries, many sugary cereals, and some snack foods can have a similar problem.
You don’t have to swear them off forever. Start by asking: What could I replace rather than simply remove?
Replace soda with water or unsweetened sparkling water. Replace a pastry with Greek yogurt and berries. Replace some refined grains with beans, vegetables, or whole grains.
Small substitutions made repeatedly can add up.
Dr. Mike’s Take
When people learn their blood sugar is elevated, they sometimes feel as though they need to fix everything immediately.
I would rather see you pick two habits you can actually maintain.
Start walking for 10 minutes after dinner. Add resistance training twice a week. Replace one sugary drink each day. Add vegetables or beans to lunch.
Then build from there.
Your blood sugar doesn’t respond to what you do perfectly for seven days.
It responds to what you repeatedly do for months and years.
One important caution: If you have diabetes and take insulin or medications that can cause low blood sugar, changes in your diet and exercise routine can sometimes change your glucose levels significantly. Talk with your healthcare team about how to exercise safely and whether your medication needs adjustment.
Bottom Line
You can’t control every factor that affects your blood sugar. Age, genetics, medications, and certain medical conditions all matter.
But your daily habits matter too.
Move after meals. Strengthen your muscles. Eat more fiber and adequate protein. Protect your sleep. Work toward a healthy weight when appropriate. And replace some highly refined carbohydrates and sugary drinks with better choices.
You don’t have to do everything tomorrow.
Pick one habit. Practice it. Then add another.
That’s how lasting change usually begins.
