12 Proven Strategies to Prevent Insulin Spikes and Enhance Your Health

Consider your body an example of a busy city, and the blood glucose levels as traffic. These blood sugar levels usually increase and fall. The amount it rises and mitigates significantly impacts your metabolic health. Smaller spikes are fine, but significant fluctuations may impact our lives in the short and long run. These insulin spikes may affect everyone’s health and metabolism, so it’s crucial to keep that in mind as we discuss this topic.

Even people with diabetes or prediabetes, in particular, need to know how to control these spikes and what causes them so that they do not damage their bodies.

Let’s first get the basics of what insulin spikes are.

What are Insulin Spikes?

Insulin spikes are a temporary rise in blood sugar levels following a meal (a postprandial spike), mainly if the meal consists of carbohydrates.

In healthy people, they are a natural element of the metabolic process that helps to maintain blood sugar levels effectively. The body’s capacity to react swiftly to these increases by changing insulin levels aids in the maintenance of a healthy blood sugar range.  This spike usually resolves itself before the body’s insulin begins its immediate action to reduce the surge.

These spikes may be more visible and prolonged for those with type 1 diabetes who are unable to manufacture insulin on their own.

Here’s a table summarizing normal blood sugar levels in most people, both fasting and after meals:

Condition Blood Sugar Level (mg/dL)
Fasting (Normal Range) 82 – 110
After Meals (Peak Level) ~140 or slightly more
Normal Blood Glucose ~90

The International Diabetes Federation suggests that glucose levels remain below 140 mg/dL after meals.

The precise moment when blood sugar levels rise might differ from one individual to another and from one meal to another. But on average, the post-meal peaks happen about an hour and 15 minutes after a meal.

The table below highlights how insulin spikes after eating differ significantly between normal individuals and those with diabetes, reflecting the underlying differences in insulin production, sensitivity, and the body’s ability to manage blood glucose levels.

Group Insulin Spikes After Eating
Normal Individuals Sharp but controlled spikes; quick return to baseline as glucose is absorbed and utilized.
Individuals with Type 1 Diabetes Dependent on administered insulin timing and dose. Variability in control is common.
Individuals with Type 2 Diabetes Muted or delayed spikes; prolonged return to baseline due to insulin resistance.

What Causes Insulin Spikes? 2605212 377113 PBTP94 52

Here are some common causes of insulin spikes:

  • High-sugar meals: The most common cause of high sugar levels is spikes in insulin levels, and quick rises in blood glucose levels may occur after consuming sugary meals and drinks, including sodas, sweets, and desserts.
  • A large portion of meals: Consuming large meals, mainly those rich in carbohydrates and sugars, can induce notable insulin spikes as the body attempts to regulate the abrupt surge of glucose.
  • Skipping breakfast: A study involving 22 type 2 diabetes patients found that skipping breakfast can lead to higher blood sugar levels throughout the day.
  • Sedentary lifestyle: Inactivity changes insulin sensitivity, increasing insulin needs for glucose uptake by cells. According to research, blood sugar levels rise after three days of reduced or no exercise in healthy, ordinarily active individuals.
  • High stress levels: Blood glucose levels might rise due to stress hormones, which increase insulin secretion. Stress increases our “fight or flight” hormone, cortisol. An increase in cortisol levels reduces insulin sensitivity.
  • Medication side effects: Blood sugar levels might increase with some medications. Some examples of such drugs include antidepressants, diuretics, corticosteroids, and some blood pressure medications.
  • Regular artificial sweetener intake: Diet sodas, coffee, and tea all include zero-calorie artificial sweeteners, but research shows that they may raise blood sugar levels and make insulin resistance and steady-state glucose tolerance even worse.
  • Less sleep: Not getting enough sleep can cause insulin spikes, as a bulk of research supports it.

If you have diabetes, you are at a higher risk of having a blood sugar spike than people without diabetes.


An individual’s specific set of symptoms during a blood sugar increase could include:

  • Frequent urination
  • Fatigue
  • Blurry vision
  • Dry mouth
  • Headache
  • Increased thirst

Effects of Blood Sugar Spikes

Short-term effects of blood sugar spikes include fatigue, headache, increased thirst, and blurred vision. However, it’s the long-term consequences that are more concerning, as repeated spikes can lead to:

Hyperglycemia Vs. Insulin Spikes

Although hyperglycemia and increased insulin spikes are both symptoms of improper glucose metabolism, they are distinct. Some major differences are mentioned here.

Feature Raised Insulin Spikes Hyperglycemia
Definition A rapid increase in insulin levels in the bloodstream following food consumption. Chronically high blood sugar (glucose) levels that exceed the normal range.
Causes Consuming foods high in glycemic index leads to quick digestion and absorption of sugars. Insufficient insulin production (Type 1 diabetes), insulin resistance (Type 2 diabetes), stress, certain medications, poor management of diet or diabetes treatment.
Effects Can lead to increased fat storage, weight gain, and eventually insulin resistance. Can cause cardiovascular disease, nerve damage, kidney damage, vision problems, diabetic ketoacidosis (Type 1), or hyperosmolar hyperglycemic state (Type 2).

Treating Insulin Spikes In Diabetics

Measure your blood sugar levels if you’re experiencing any of the symptoms mentioned earlier. If it’s high, doing some activity, even if it’s only a 10- or 15-minute stroll, could help bring it down.

Check for ketones if the blood sugar level is above 240 mg/dL. High glucose levels can cause the body to burn stored fat for energy, producing ketones and acid. Exercising during high ketone levels can worsen blood sugar rises and potentially cause ketoacidosis, a potentially fatal illness. Home testing for ketones can be done using a glucose meter or urine test kit.

Avoid physical activity, and seek medical advice if ketones are detected. High glucose levels can cause the body to burn stored fat for energy, producing ketones and acid.

Monitor sugar levels

Regular monitoring of blood sugar levels is important for everyone, but especially for those who use insulin or other medications that directly impact blood sugar levels.

In order to keep blood glucose levels steady all day long, research shows that eating smaller, more frequent meals is better than eating fewer, larger meals.

Preventing Insulin Spikes

A visit to the emergency room isn’t always necessary when blood sugar levels rise. Preventing glucose spikes is the only foolproof method for keeping them to a minimum.

Your blood sugar levels may be reduced with some home treatments,

1. Take Note of When You Eat.

Being mindful of what you eat is essential. Some individuals have a smaller breakfast and two larger meals at noon and supper. Your blood sugar levels may rise suddenly if you do this. In its place, try eating a few small, well-balanced meals spread out throughout the day.

Also, it is suggested that insulin sensitivity is strongest in the morning and lowest at night. So, eating larger meals in the morning and early afternoon, when insulin levels are highest and glucose control is best, may be suitable for your metabolism.

Splitting your meal into two smaller portions is another option. Try eating half your supper around 5 p.m. and the other half a couple hours later instead of having a single dinner at 7 p.m.

2. Eating Order: Managing Glucose and Insulin

For those with diabetes or who are trying to improve their metabolic health, the order in which they eat may have a major influence on insulin spikes and the general control of blood glucose levels.

It has been shown that the order in which certain items are eaten at mealtimes may influence insulin levels and postprandial glucose levels in the blood.

Here’s how the sequence in which you eat might affect these results:

Starting with Fiber-Rich Vegetables and Proteins

Reduced post-meal blood glucose and insulin levels have been associated with starting meals with protein- and fiber-rich veggies rather than carbs. In other words, consuming carbohydrate-heavy meals causes blood sugar levels to increase more rapidly, so saving the carbs for last may be more effective.

This is because slower digestion and glucose absorption into the circulation are the outcomes of a diet high in fiber and protein. The gradual absorption of glucose and insulin helps to avoid dangerously high blood glucose and insulin levels.

A 2010 study found that 15 Type 2 diabetes patients who ate vegetables and white rice dishes first experienced a 20% lower peak blood glucose and a 30% decrease in blood insulin levels at the 30- and 60-minute mark.

In another 2019 Chinese study, optimal blood sugar levels were achieved by following this order: veggies, meat, and rice. A recent 2023 research also advocated this method to be very effective.

The insulin spike that results from eating carbohydrates is lessened if protein, fat, or fiber are consumed first, rather than all at once.

How does it work? 

The process of stomach emptying is slowed down by eating the vegetables first. When fiber-rich vegetables reach the small intestine, their viscosity increases, making it harder for sugars and starches to interact with digestive enzymes, further delaying their digestion and absorption.

If we decided to put this study into practice, we could have salads or vegetable soups as our first course, then lean proteins like chicken, fish, or tofu, and lastly, starchy vegetables or complete grains. In addition to assisting with insulin and blood glucose control, this method may increase satiety and food consumption in general.

Preloading Method

The preloading method, like food sequencing, lowers blood sugar levels after meals by deliberately arranging macronutrients. Yet, the intervals between portions in this method are somewhat greater.

A 2016 study found that consuming 40 grams of soy protein 30 minutes before a sugary beverage significantly reduced peak and cumulative blood glucose levels.

Another 2015 study found that consuming a mixed preload of fat and protein 30 minutes before drinking a sugary beverage reduced blood sugar significantly. People with type 2 diabetes saw the greatest benefit (49% lower insulin spike), while prediabetes experienced a moderate 37% reduction. Standard glucose tolerance saw a 32% reduction.

The standard recommendation is to have a dish of fat, protein, or fiber 30 minutes before a large meal; however, the interval between meals may be anything from 15 minutes to 2 hours.

But still, due to the change in habits required and the reduced likelihood of unintended weight gain, a “carbs last” strategy may be preferable to preloading.

Combining tips for maximum result

3. Opt for a balanced diet.

Adhere to a balanced diet and pay attention to the food’s quality.

Reduce processed foods, as they can increase glucose spikes and cause hunger. These meals ‘ high-calorie, fat, sugar, salt, and low fiber content break down rapidly, leading to blood sugar spikes. Other harmful substances in these items include cereals, granola bars, drinks, packaged snacks, and cooked dinners. It’s essential to avoid these unhealthy options.

4. Loose weight

Losing weight can also have a very profound effect on insulin spikes in both diabetics and healthy individuals. A study found that 35 obese participants who consumed 1,600 calories daily lost an average of 14.5 pounds over 12 weeks, and their blood sugar levels decreased by 14%.

In another study of individuals without diabetes, it was found that weight loss reduced the risk of developing type 2 diabetes by 58%.

5. Reduce Stressors.

If you have figured out that stress is the main cause of high sugar levels, then to relax, you can try exercising, meditating, or practicing deep breathing. Practicing yoga regularly is also a good choice. It is well acknowledged that yoga activities alleviate stress and prevent post-meal blood sugar rises.

6. Consider using Berberine

Berberine is a substance that has been used by the Chinese for centuries and has beneficial effects on lowering blood glucose levels. Evidence suggests it may be just as helpful as some medications for type 2 diabetes.

A study involving 116 type 2 diabetes patients found that berberine reduced post-meal blood sugar rises by 25% over three months.

Consuming berberine can be beneficial in reducing insulin spikes, but if you have any health issues or are on any medications, you should talk to your doctor before using it.

7. Use Spices

Fenugreek Seeds: A lesser-known benefit of fenugreek seeds is their reduced blood sugar levels. They have been found to alleviate glucose intolerance and reduce blood sugar levels, especially in people with diabetes. In another 2017 study, it was found that people who consumed fenugreek seeds had healthier glucose levels and fewer insulin spikes than those who didn’t.

So, there is no harm in trying it; you can toss them into baked items or brew them in tea.

Cinamon: Like fenugreek seeds, studies on healthy individuals have shown that cinnamon may improve insulin sensitivity and lessen the occurrence of blood sugar rises after consuming carbohydrates. (1)(2)(3)(4).

So, consuming it under the recommended intake (1 gram) cannot harm the body.

8. Move After Eating

Exercise is beneficial for healthy people and those with pre-diabetes and diabetes equally.

According to several studies, the absorption of glucose from the blood into the muscles, which is used to produce energy in the form of ATP, is enhanced when exercise is performed within an hour after consuming a carbohydrate-containing meal.

A brisk walk after a meal is another great way to lower the sugar levels. It may also slow down the passage of food from your stomach to your lower bowels. A meta-analysis conducted in 2022 showed that even a little stroll of two minutes might substantially impact your body’s glucose response.

Can’t go for a walk? Any movement—cleaning, dancing, squats—will help.

9. Avoid Eating Late At Nightindex im02

Insulin is released in low-level pulses every day that are linked to your circadian cycle.

It means insulin sensitivity is greatest first thing in the morning and lowest after dark. Hence, for optimal metabolic health, it may be best to eat heavier meals in the morning or early afternoon when insulin levels peak and glucose control is at its greatest.

10. Take Apple Cider Vinegar

The magic ingredient in apple cider vinegar can also help to reduce blood sugar levels in the body, as per studies (1)(2). Another research investigated how vinegar affected blood sugar levels after carbohydrate consumption. The results showed that vinegar improved insulin sensitivity by 19% to 34%.

Vinegar’s active component, acetic acid, modulates glucose metabolism in two ways: Because it blocks the action of the alpha-amylase enzyme, glucose is absorbed more slowly by the intestines. On the other hand, it enhances glucose uptake by muscle cells, allowing for faster glucose removal from the blood, especially during exercise.

The citric acid found in lemon juice is another substance that might affect blood sugar levels.

In most cases, raw, organic apple cider vinegar is the way to go. The concentration of good bacteria will be greater, and it can be foggy. One option is to use two teaspoons of apple cider vinegar in a large glass of water; another is to use it as a salad dressing, which is healthier and more delicious.

11. Sleeping Enough

Your blood sugar levels might be affected by your sleeping patterns. According to research conducted in 2021, even one night of bad sleep may lead to greater blood sugar the next day. This finding further supports the idea that sleep quality is significantly related to blood glucose regulation.

Both the amount and quality of sleep are necessary. According to research, the most crucial stage of sleep for regulating blood sugar is non-REM (deepest level of sleep).

One should aim for seven or eight hours of sleep every night by following excellent sleep hygiene—a cool, dark bedroom, no screens for at least a few hours before bed, a regular bedtime routine, and no electronics in the room.

12. Drink More Water

When you’re not getting enough water in your system, your kidneys secrete the hormone vasopressin, which stops your body from excreting sugar in urine. More sugar will be released into your circulation by your liver due to this signal.

That is why hydration is the key to maintaining optimal sugar levels. As it has been studied in research, the risk of developing high blood sugar was 21% lower in 3,615 individuals who consumed 34 ounces (or about 1 liter) of water daily than those who consumed 16 ounces (473 ml) or less.

There is a debate about the optimal amount of water consumed daily. The key is that it’s person-specific. To learn more about the benefits of water intake, read here

If you have diabetes or a few other medical issues, it is essential to watch those insulin spikes. If that’s the case, you may prevent hazardous rises in blood sugar by following the advice of your treating doctor or a registered nutritionist. One piece of suggestion may be to sequence foods.

For the rest of us, there’s no need to stress about the proper sequence in which to consume our meals. However, to keep glucose surges to a minimum, cut out sugary drinks and bulk out carbs with protein, fat, or fiber.

People may improve their health and reduce the likelihood of consequences from high blood sugar by making educated decisions about their daily lives and seeing a doctor when needed.
