View Doctor Profile →Habits that increase diabetes risk are often part of everyday life—such as sitting for long periods, regularly drinking sugary beverages, eating highly processed foods, smoking, or consistently getting poor sleep. None of these habits means that someone will definitely develop diabetes, but several can contribute to a higher risk of type 2 diabetes, especially when they occur together.
The good news is that many diabetes risk factors are modifiable. The 2026 American Diabetes Association (ADA) Standards of Care emphasize healthy eating patterns, regular physical activity, weight management when appropriate, and diabetes-prevention programs for adults at high risk.
This guide explains which everyday habits may raise type 2 diabetes risk, why they matter, and practical ways to replace them with healthier routines.

Quick Answer: What Habits Increase Diabetes Risk?
Some of the most important modifiable habits associated with a higher risk of type 2 diabetes include:
- Being physically inactive
- Sitting for prolonged periods
- Frequently drinking sugary beverages
- Eating a diet high in refined and highly processed foods
- Regularly overeating or consuming excess calories
- Smoking or using tobacco products
- Consistently getting inadequate or irregular sleep
- Ignoring prediabetes or skipping recommended screening
- Relying on extreme or unsustainable diets
- Avoiding healthy weight management when appropriate
These habits don’t work in isolation. Genetics, age, family history, previous gestational diabetes, certain medical conditions, and other factors also influence diabetes risk.
1. Being Physically Inactive
A sedentary lifestyle is one of the most important modifiable risk factors for type 2 diabetes.
Your muscles use glucose for energy, and regular physical activity can improve insulin sensitivity and support metabolic health. The CDC identifies being physically active less than three times a week as a risk factor for type 2 diabetes.
You don’t have to become a serious athlete to become more active.
Try instead:
- Take a brisk walk
- Use stairs when practical
- Walk during work breaks
- Cycle or swim
- Do household activities
- Add resistance exercises
- Choose activities you actually enjoy
For adults at high risk of type 2 diabetes, the 2026 ADA Standards recommend working toward at least 150 minutes of moderate-intensity physical activity per week.
Can Prediabetes Be Reversed? What the Evidence Says
2. Sitting for Long Periods Without Breaks
You can technically exercise and still spend most of the day sitting.
Long periods of sedentary time are increasingly recognized as an important part of metabolic health. The ADA recommends interrupting prolonged sitting, noting potential benefits for blood glucose and other health outcomes.
A simple strategy
If you work at a desk, try getting up regularly to:
- Walk around the room
- Stretch
- Get water
- Take a short walking break
- Stand during a phone call
These small movements don’t replace structured exercise, but they can make your overall day less sedentary.
3. Drinking Sugary Beverages Frequently
Regular consumption of sugar-sweetened beverages can make it easier to consume excess calories and added sugars.
Examples include:
- Regular soda
- Sweetened iced tea
- Fruit drinks with added sugar
- Sweetened energy drinks
- Sugary coffee beverages
- Some flavored drinks
The ADA’s 2026 nutrition recommendations encourage minimizing sugar-sweetened beverages, sweets, refined grains, and highly processed foods in people with prediabetes or diabetes.
Better everyday choices
Depending on your preferences, choose:
- Water
- Sparkling water without added sugar
- Unsweetened tea
- Unsweetened coffee
- Water with fresh citrus for flavor
You don’t have to change everything overnight. Replacing one sugary drink at a time can be a practical starting point.
How to Prevent Type 2 Diabetes
4. Eating Highly Processed Foods Too Often
Not every processed food is unhealthy. Processing can include simple things such as freezing, cooking, or pasteurizing.
The bigger concern is relying heavily on foods that are highly processed and rich in refined carbohydrates, added sugars, sodium, or calories while providing relatively little fiber and nutritional value.
Examples can include:
- Sugary baked goods
- Refined snack foods
- Many packaged desserts
- Highly refined grain products
- Sugar-heavy breakfast foods
- Some fast-food meals
The 2026 ADA Standards recommend eating patterns that emphasize nonstarchy vegetables, whole fruits, legumes, lean proteins, whole grains, nuts, and seeds, while minimizing refined and ultraprocessed foods.
Try this approach
Instead of focusing on a list of “forbidden” foods, build most meals around minimally processed, nutrient-dense foods.
5. Frequently Eating More Calories Than Your Body Needs
Consistently consuming more energy than your body uses can contribute to weight gain.
For people who have overweight or obesity and are at increased risk of type 2 diabetes, weight management can be an important part of prevention. The 2026 ADA Standards recommend a goal of approximately 5–7% weight reduction for appropriate high-risk adults with overweight or obesity participating in diabetes prevention efforts.
However, weight is only one part of diabetes risk.
Avoid blaming yourself for diabetes risk based on body size alone. Genetics, medications, sleep, activity, socioeconomic factors, medical conditions, and many other factors can influence metabolic health.
A more useful goal
Focus on sustainable habits rather than crash diets:
- Regular meals
- More vegetables and fiber
- Appropriate portions
- Regular movement
- Adequate sleep
- Long-term consistency
6. Smoking or Using Tobacco Products
Smoking isn’t only a lung-health issue.
The CDC reports that smokers have a 30%–40% higher risk of developing type 2 diabetes than people who don’t smoke, with risk increasing with greater tobacco exposure. Nicotine and other chemicals in tobacco can affect glucose regulation and inflammation.
If you smoke, quitting is one of the most valuable changes you can make for your overall health.
Quitting may be difficult, and needing several attempts is common. Healthcare professionals can help you choose evidence-based cessation strategies.

7. Consistently Getting Poor or Irregular Sleep
Sleep is often overlooked when people talk about diabetes prevention.
Research summarized by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) links insufficient, irregular, and disrupted sleep with impaired glucose tolerance and reduced insulin sensitivity. Sleep disorders such as obstructive sleep apnea are also associated with metabolic problems.
Improve your sleep routine
Try:
- Going to bed and waking at consistent times
- Keeping your bedroom comfortable and dark
- Limiting stimulating activities close to bedtime
- Reducing late-night screen exposure
- Avoiding excessive caffeine late in the day
If you regularly snore loudly, wake up gasping, or remain excessively tired during the day, talk with a healthcare professional about possible sleep problems.
8. Ignoring Prediabetes
Prediabetes is not the same as diabetes, but it is an important warning sign.
People with prediabetes have a higher risk of developing type 2 diabetes. The important point is that prediabetes provides an opportunity to intervene early.
Ignoring an abnormal blood glucose or A1C result can mean missing an opportunity to address risk factors.
If you’ve been diagnosed with prediabetes
Talk with a healthcare professional about:
- Your individual diabetes risk
- Nutrition
- Physical activity
- Weight management if appropriate
- Follow-up testing
- Diabetes prevention programs
The ADA recommends evidence-based diabetes prevention programs for adults at high risk.
9. Following Extreme, Short-Term Diets
A very restrictive diet may produce rapid changes, but it may be difficult to maintain.
Examples include diets that:
- Eliminate entire food groups without medical reason
- Rely on very low calorie intake
- Promise rapid “blood sugar resets”
- Depend on supplements or detox products
- Claim to permanently prevent diabetes through one food
There is no single perfect diabetes-prevention diet for everyone.
The 2026 ADA Standards recognize several evidence-based eating patterns and emphasize individualization based on food preferences, nutritional needs, and metabolic goals.
A sustainable eating pattern is generally more useful than repeatedly starting and abandoning restrictive diets.
10. Avoiding Regular Health Screening
Some people don’t realize they have prediabetes because it may not cause obvious symptoms.
Type 2 diabetes can also develop gradually, and some people have few noticeable symptoms for a long time.
If you’re at increased risk, ask your healthcare professional whether diabetes or prediabetes screening is appropriate.
Risk factors can include:
- Prediabetes
- Overweight or obesity
- Family history of type 2 diabetes
- Physical inactivity
- Older age
- Previous gestational diabetes
- Certain health conditions
Not everyone has the same screening needs, so your healthcare professional can recommend an appropriate schedule.
Habits That Increase Diabetes Risk vs. Healthier Alternatives
| Risk-increasing habit | Healthier alternative |
|---|---|
| Sitting most of the day | Take regular movement breaks |
| Little or no exercise | Build toward regular moderate activity |
| Frequent sugary drinks | Choose water or unsweetened beverages |
| Frequent highly processed foods | Emphasize whole or minimally processed foods |
| Regular overeating | Use portions that fit your individual needs |
| Smoking | Seek evidence-based smoking cessation support |
| Irregular sleep | Establish a consistent sleep routine |
| Ignoring prediabetes | Follow up with your healthcare professional |
| Crash dieting | Choose sustainable eating habits |
| Skipping recommended screening | Discuss appropriate screening with your doctor |
Are All Diabetes Risk Factors Within Your Control?
No.
This is important because diabetes risk is not simply a matter of personal choices.
Some factors cannot be changed, including:
- Age
- Family history
- Genetic susceptibility
- Previous gestational diabetes
- Certain medical conditions
NIDDK notes that family history, age, physical inactivity, overweight or obesity, prediabetes, and a history of gestational diabetes can all affect type 2 diabetes risk.
So the goal isn’t to eliminate every risk factor.
The goal is to address the factors you can reasonably change while getting appropriate medical care for the factors you cannot.
What Are the Most Important Habits to Change First?
You don’t need to overhaul your entire lifestyle in one week.
A practical starting point is to focus on these five areas:
1. Move More
Start with walking or another activity you enjoy.
2. Replace Sugary Drinks
Water or unsweetened beverages can be an easy swap.
3. Improve Meal Quality
Add vegetables, whole grains, legumes, whole fruits, nuts, seeds, and appropriate protein sources.
4. Stop Smoking
If you smoke, seek professional support for quitting.
5. Improve Sleep
Work toward a consistent and sufficient sleep routine.
These changes align with the lifestyle approaches emphasized in current diabetes-prevention guidance.
A Simple 30-Day Diabetes-Risk Reduction Plan
Instead of trying to change everything immediately, consider a gradual approach.
Week 1: Move More
- Take short walks
- Break up sitting time
- Choose stairs when appropriate
- Track your activity
Week 2: Improve Drinks
- Replace regular soda with water
- Choose unsweetened tea or coffee
- Reduce sugary beverages
Week 3: Improve Meals
- Add more nonstarchy vegetables
- Choose whole grains more often
- Include beans, lentils, nuts, seeds, and appropriate protein
- Reduce highly processed foods
Week 4: Build Long-Term Habits
- Maintain regular activity
- Work on sleep consistency
- Address smoking if applicable
- Schedule recommended health screening
- Consider a diabetes prevention program if you’re at high risk
The objective isn’t perfection.
The objective is consistency.
Can You Lower Your Risk of Type 2 Diabetes?
For many people, yes.
The CDC states that type 2 diabetes can be prevented or delayed through lifestyle changes, particularly among people at increased risk.
The landmark Diabetes Prevention Program found that intensive lifestyle intervention reduced the development of type 2 diabetes by 58% over three years among high-risk participants. The 2026 ADA Standards continue to cite this evidence and recommend structured prevention programs for adults at high risk.
That doesn’t mean everyone can prevent diabetes.
It means that early action can make a meaningful difference for people at elevated risk.
When Should You Talk to a Doctor?
Consider speaking with a healthcare professional if you:
- Have been diagnosed with prediabetes
- Have a strong family history of type 2 diabetes
- Have previously had gestational diabetes
- Are concerned about your diabetes risk
- Have multiple risk factors
- Have had an abnormal glucose test
- Want help with sustainable weight management
- Are unsure how much physical activity is appropriate for you
A healthcare professional can assess your individual risk rather than relying on general online advice.
Bottom Line
Habits that increase diabetes risk often involve inactivity, prolonged sitting, frequent sugary drinks, highly processed foods, smoking, poor sleep, and ignoring important health screenings. These behaviors don’t guarantee that someone will develop type 2 diabetes, but they can contribute to risk—especially when combined with other risk factors.
The good news is that many lifestyle factors are changeable.
You don’t need a perfect diet, an extreme workout plan, or a “miracle” solution. Start with realistic changes you can maintain: move more, eat more nutrient-dense foods, reduce sugary drinks, avoid tobacco, prioritize sleep, and stay aware of your health numbers and risk factors.
If you have prediabetes or are at high risk, consider discussing a structured diabetes prevention program with your healthcare professional. Current ADA guidance supports evidence-based lifestyle intervention, including appropriate weight management, healthier eating patterns, and regular physical activity.

8. Can overeating increase diabetes risk?
Consistently consuming more calories than your body needs can contribute to weight gain and may increase type 2 diabetes risk in susceptible people. Portion awareness and a balanced eating pattern can help.
9. Can prediabetes turn into diabetes?
Prediabetes increases the risk of developing type 2 diabetes, but progression isn’t inevitable. Lifestyle changes and appropriate medical follow-up can help reduce or delay that risk.
10. Can walking help reduce diabetes risk?
Yes. Regular walking is a practical form of physical activity that can contribute to better fitness and metabolic health. For people at increased risk, building toward at least 150 minutes of moderate activity per week is commonly recommended.
11. How can I reduce my diabetes risk naturally?
Focus on sustainable habits such as regular physical activity, nutritious meals, limiting sugary beverages, avoiding tobacco, getting adequate sleep, managing weight when appropriate, and following recommended screening.
12. Does family history mean I will get diabetes?
No. A family history can increase your risk, but it does not mean that developing type 2 diabetes is inevitable. Modifiable lifestyle factors and appropriate medical care still matter.
13. What is the biggest diabetes risk factor I can change?
There isn’t one universal factor for everyone. Physical inactivity, excess weight when applicable, unhealthy dietary patterns, smoking, and poor sleep can all be relevant. Your personal risk profile determines which changes are most important.
14. Can healthy habits prevent type 2 diabetes completely?
Healthy habits can substantially reduce or delay risk for many people, but they cannot guarantee prevention. Some risk factors, including age and genetics, cannot be changed.
15. When should I get tested for diabetes or prediabetes?
People with risk factors may benefit from screening even when they feel well. Ask your healthcare professional when testing is appropriate based on your age, family history, weight, previous pregnancy history, and other risk factors.
Conclusion
Habits that increase diabetes risk are often changeable, which means prevention can start with realistic everyday decisions. Moving more, reducing prolonged sitting, choosing healthier foods and beverages, avoiding tobacco, prioritizing sleep, and addressing prediabetes early can all support better long-term metabolic health.
You don’t need to change everything at once. Small, sustainable improvements are more useful than short-term extreme diets or unrealistic routines.
If you have several diabetes risk factors or have been diagnosed with prediabetes, speak with a healthcare professional about screening and evidence-based diabetes prevention options.
The goal isn’t perfection—it is building healthier habits that you can maintain over time.
