Best diets for people with diabetes in 2024

Eating healthy with diabetes

There’s no one-size-fits-all diet recommendation for people with diabetes. What works for one person may not work for another. Your specific health history, chronic diseases, lifestyle, and environment can impact how your body responds to one eating pattern Also know as a diet or dietary pattern, what people eat and drink on a regular basis. vs. another. 

The American Diabetes Association (ADA) says a healthy eating plan includes [3] American Diabetes Association. Tips for Eating Well. Found on the internet at https://diabetes.org/food-nutrition/eating-healthy :

How to get started

Eating healthy doesn’t have to be overwhelming. The ADA has a few tips and an easy method to get started on managing your blood sugar through your diet. Using the Diabetes Plate Method is an easy way to make sure each meal is balanced and encourages the following on each plate [4] American Diabetes Association. What is the Diabetes Plate Method?

Risks of low blood sugar

Hypoglycemia, or low blood sugar, can be a medical emergency if you don’t act on it. People with diabetes are at risk of hypoglycemia, especially people who have type 1 diabetes or who are taking insulin or other blood sugar–regulating drugs. Symptoms of low blood sugar are sweating, shaking, confusion, dizziness, and hunger. People with very low blood sugar can feel weak, have seizures, or faint.

Diabetes medication can cause low blood sugar. Also, the timing of physical activity and your eating patterns can lead to low blood sugar. People who are changing their diets should consult with their health care team beforehand to support balanced blood sugar levels. [5] Centers for Disease Control and Prevention. Low Blood Sugar (Hypoglycemia). Dec. 20, 2022. Found on the internet at https://www.cdc.gov/diabetes/basics/low-blood-sugar.html

People should work with their health care team to understand how their bodies respond to certain foods, activities, and stressors and how that impacts their blood sugar regulation. Ultimately, a supportive health care team can recommend a sustainable lifestyle—like diet, physical activity, exercise, mental health, and rest—that supports healthy blood sugar regulation.

Best diet plans for people with diabetes, reviewed by experts

Mediterranean diet

Mediterranean diet

Based on eating patterns of certain Mediterranean traditions
Benefits for type 2 diabetes and heart disease
Key features
  • Plenty of fruits, vegetables, whole grains, beans, nuts, and seeds
  • Olive oil as the main source of fats
  • Low to moderate amounts of dairy, eggs, fish, and chicken
  • Limited amounts of red meat, sweets, added sugars, and highly processed foods
Pros and cons of the Mediterranean diet plan
Pros Encourages lots of fruits and vegetables Benefits for the management of type 2 diabetes and heart disease Encourages social and physical wellness as part of a healthy lifestyle Cons Not a standardized diet Includes small amounts of wine, which isn’t advised for everyone

How does the Mediterranean diet work?

The Mediterranean diet is based on the eating patterns of various Mediterranean cultures in the early 1960s: Cretan, Greek, and southern Italian. [6] Sikalidis AK, et al. Mediterranean Diet. Encyclopedia. Apr. 25, 2021. Found on the internet at https://www.mdpi.com/2673-8392/1/2/31 It was first studied because these populations were found to have longer life spans and low rates of chronic diseases, some cancers, and obesity. The Mediterranean diet is actually a lifestyle that encourages regular physical activity and plenty of plant foods such as fruits, vegetables, whole grains, beans, nuts, and seeds. [6] Sikalidis AK, et al. Mediterranean Diet. Encyclopedia. Apr. 25, 2021. Found on the internet at https://www.mdpi.com/2673-8392/1/2/31

There’s no calorie counting in the Mediterranean diet. Instead, it emphasizes eating certain proportions of food groups. The diet is proposed as a pyramid, with plant foods at the base of the pyramid and red meats at the top, eaten infrequently. Olive oil is the main source of fat in the diet, and dessert is typically fresh fruit. Alcohol in the form of wine is also included in low to moderate amounts with meals. [6] Sikalidis AK, et al. Mediterranean Diet. Encyclopedia. Apr. 25, 2021. Found on the internet at https://www.mdpi.com/2673-8392/1/2/31  

Our expert take

The Mediterranean diet is recommended by the Centers for Disease Control and Prevention (CDC) and the American Heart Association (AHA) for people managing diabetes, and our Reviews Team found a fair amount of evidence supporting these recommendations. A 2020 review of studies found that the Mediterranean diet decreased the risk of developing type 2 diabetes by up to 23% in healthy adults and 52% in older adults with a high risk of heart disease. [7] Martín-Peláez S, et al. Mediterranean Diet Effects on Type 2 Diabetes Prevention, Disease Progression, and Related Mechanisms. A Review. Nutrients. Jul. 27, 2020. Found on the internet at https://www.mdpi.com/2072-6643/12/8/2236  

Kimberly Gomer, RD, in Miami, Florida, highlighted that the plant foods and whole foods in the Mediterranean diet can be beneficial for people with diabetes, but some aspects of the diet may work against some people. For example, the Mediterranean diet encourages drinking wine in moderation, but some people may need to abstain from alcohol altogether to benefit blood sugar regulation.

The Mediterranean diet can be good for people who want to make dietary changes without having to look closely at nutrition labels to count calories or carbs. The flexibility can work for some, but if you do better with more structured recommendations, such as daily serving goals or nutrient limits, you may want to consider other diet options we detail below. 

Why the Mediterranean diet works for diabetes

According to the CDC, the Mediterranean diet can improve insulin resistance because of its emphasis on plant foods and its restriction on processed foods. Plant foods add fiber to the diet, can reduce inflammation, and typically contain healthy fats that can help with blood sugar and weight management. [8] Centers for Disease Control and Prevention. Healthy Eating for People with Diabetes. Dec. 6, 2022. Found on the internet at https://www.cdc.gov/diabetes/library/features/mediterranean-style-eating.html

Studies have found that the Mediterranean diet successfully decreases hemoglobin A1c (HbA1c) A blood test that measures your average blood sugar levels over the previous three months. HbA1c levels are often used to diagnose and monitor type 2 diabetes. levels compared to low-fat or low-carb diets. Researchers think this is because of its anti-inflammatory actions, effects on hormones that regulate digestion and sugar control, and the effects on gut bacteria. [7] Martín-Peláez S, et al. Mediterranean Diet Effects on Type 2 Diabetes Prevention, Disease Progression, and Related Mechanisms. A Review. Nutrients. Jul. 27, 2020.

Low-carb diet

Low-carb diet

Decreased intake of carbohydrates
Benefits for weight management and diabetes
Key features
  •  Limits added sugars and refined carbohydrates
  • Focus is on non-starchy vegetables and proteins
  • Daily limit of 20–130 grams (g) of carbohydrates per day
Pros and cons of the Low-carb diet
Pros Used as a strategy for weight management Can improve blood sugar control Cons Daily carbohydrate limits can vary Moderation is still needed for other food groups

How does the low-carb diet work?

The low-carb diet involves limiting the amount of carbohydrates (carbs) in the daily diet to decrease insulin and improve metabolic health. Depending on the source of the carbohydrates, the recommended daily carb limit can be 20 g per day and up to 130 g per day. Less than than 50 g of carbs per day is considered a “very low” carb diet, which can also be considered the ketogenic (“keto”) diet. [9] Oh R, et al. Low-Carbohydrate Diet. StatPearls [Internet] Aug. 17, 2023. Found on the internet at https://www.ncbi.nlm.nih.gov/books/NBK537084/

Insulin and diabetes

Insulin is a hormone that the pancreas secretes in response to food intake. It signals for the body’s cells to take in sugar from the blood for energy. People with type 2 diabetes have cells that require increasing amounts of insulin to take in sugar from the blood. [10] American Diabetes Association. Insulin Basics. Found on the internet at https://diabetes.org/health-wellness/medication/insulin-basics This is called insulin resistance.

The goal of diabetes treatment is to restore proper insulin signaling and reduce high levels of sugar in the blood.

Carbohydrates are broken down into sugar that the body uses for energy. Eating high amounts of carbohydrates means that there’s a large supply of sugar for the body’s cells. If regularly unused, this supply of energy can turn into weight gain or insulin resistance. The low-carb diet supports the body’s metabolism and weight management by reducing the amount of carbs consumed. 

Our expert take

Low-carb diets have been found to be better than low-fat diets at helping people lose weight and sustain weight loss, but the challenge with the low-carb diet is sticking to it. [9] Oh R, et al. Low-Carbohydrate Diet. StatPearls [Internet] Aug. 17, 2023. Found on the internet at https://www.ncbi.nlm.nih.gov/books/NBK537084/ “One of the things that makes managing diabetes hard is that we ask most people to limit their carbohydrates each meal,” said Nobis-Wichman.

Carbohydrates are a macronutrient—a nutrient that is found in large amounts in most diets. It can be a challenge to avoid or limit them without understanding the nutritional breakdown of typical foods. To better understand your carb intake, you can start by looking at nutritional labels or by using food-tracking apps like Noom, Cronometer, or MyFitnessPal. The U.S. Department of Agriculture (USDA) also maintains a searchable food database that includes carb counts of common foods. 

Info icon

Examples of carb content in typical foods [11] U.S. Department of Agriculture. FoodData Central Search Results. Found on the internet at https://fdc.nal.usda.gov/fdc-app.html#/

  • Egg sandwich on a bagel: 89 g
  • Ham and turkey sandwich on white bread: 31 g
  • One medium apple: 30 g
  • 1 cup of spaghetti pasta with sauce and meatballs: 64 g

Nobis-Wichman recommends that most of her patients consume 30–60 g of carbohydrates per meal. “Initially, this can feel very limiting. But I try to frame it as a carbohydrate budget, and the bank refreshes each meal. This gives people the freedom to decide how they want to ‘spend’ their carbs within that meal,” she said. 

Though carbs are limited in the low-carb diet, no guidelines exist around daily calorie limits. This can also work against people who are looking to manage their weight, diabetes, or other health conditions. 

Low-carb diets have been found to improve certain markers of heart disease, such as triglycerides The concentration of digested fat compounds in the blood. and HDL cholesterol High-density lipoprotein (HDL) cholesterol concentration in the blood. HDL cholesterol is sometimes called the “good” cholesterol that helps protect against heart disease. , but their overall impact on heart disease risk is still unclear based on current research. When people eating low-carb diets add more protein to their diet, the increased protein can work against people managing chronic kidney disease. [9] Oh R, et al. Low-Carbohydrate Diet. StatPearls [Internet] Aug. 17, 2023. Found on the internet at https://www.ncbi.nlm.nih.gov/books/NBK537084/  

Finally, it’s important to keep track of your micronutrients while on a low-carb or keto diet to make sure you’re getting the right amounts of vitamins and minerals for your health goals. 

Why the low-carb diet works for diabetes

Reducing carbs is a typical dietary strategy to manage either type 1 or type 2 diabetes. Fewer carbs mean less sugar in the blood to control, which allows the body to respond to blood sugar and insulin levels more effectively. [9] Oh R, et al. Low-Carbohydrate Diet. StatPearls [Internet] Aug. 17, 2023. Found on the internet at https://www.ncbi.nlm.nih.gov/books/NBK537084/ In addition, low-carb diets support weight loss, which helps with better blood sugar regulation. [12] Centers for Disease Control and Prevention. Healthy Weight. Dec. 30, 2022. Found on the internet at https://www.cdc.gov/diabetes/managing/healthy-weight.html Studies have found that eating low-carb diets for more than 12 months can reduce the amount of insulin, oral diabetes medications, and HbA1c levels in people with type 2 diabetes. [13] McKenzie AL, et al. A Novel Intervention Including Individualized Nutritional Recommendations Reduces Gemoglobin A1c Level, Medication Use, and Weight in Type 2 Diabetes. JMIR Diabetes. 2017. Found on the internet at https://diabetes.jmir.org/2017/1/ Reviews of research have also suggested that eating a low-carb diet for more than six months can also be a way to reverse diabetes, though more research is needed for its long-term effects.

DASH diet

DASH diet

Originally created to help manage high blood pressure and “bad” cholesterol
Low in fat and added sugar
Key features
  • Focuses on vegetables, fruits, and whole grains
  • Limits foods high in fats such as red meats, dairy, and oils
  • Limits foods with added sugars and sodium in the diet
Pros and cons of the DASH diet
Pros Can benefit people with high cholesterol and high blood pressure Can help reduce insulin resistance in people with diabetes Extra health benefits when combined with regular exercise Cons Doesn’t take into account carb intake limits Requires more planning to follow recommended servings and calorie limits

How does the DASH diet work?

DASH stands for “dietary approaches to stop hypertension.” It was developed to reduce sodium, lower blood pressure, and support overall heart health. It’s recommended by the AHA and has more structured guidelines compared to the Mediterranean and low-carb diets. The DASH diet encourages vegetables, fruits, and whole-grain foods while limiting fatty meats, full-fat dairy, and foods with added sugars and sodium. [15] National Heart, Lung, and Blood Institute. DASH Eating Plan. Dec. 29, 2021. Found on the internet at https://www.nhlbi.nih.gov/education/dash-eating-plan Your health care professional can tailor total daily calorie limits and sodium levels according to your health goals, age, gender, and health conditions. [16] MedlinePlus. Understanding the DASH Diet. Aug. 15, 2022. Found on the internet at https://medlineplus.gov/ency/patientinstructions/000784.htm   

The National Heart, Lung, and Blood Institute gives this following example of recommendations for a 2,000-calorie daily diet:

Nuts, seeds, beans, and peas are limited to four to five servings per week, and sweetened foods such as sodas and desserts are limited to five or fewer servings per week. [15] National Heart, Lung, and Blood Institute. DASH Eating Plan. Dec. 29, 2021. Found on the internet at https://www.nhlbi.nih.gov/education/dash-eating-plan The DASH diet also recommends limiting alcohol, deep-fried foods, and packaged snacks, which can be high in fats, sodium, and added sugar. [16] MedlinePlus. Understanding the DASH Diet. Aug. 15, 2022. Found on the internet at https://medlineplus.gov/ency/patientinstructions/000784.htm  

Our expert take

Similar to the Mediterranean diet, the DASH diet encourages more servings of plant foods and whole foods. Although whole foods naturally contain sodium, processed foods (e.g., packaged snacks, canned foods, or instant frozen meals) and restaurant foods account for 70% of our sodium intake. [17] American Heart Association. Sodium Sources: Where Does All That Sodium Come From? Jan. 5, 2023. Found on the internet at https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/sodium/sodium-sources Lowering sodium in our diet can help reduce blood pressure, which is one of the factors that contribute to heart disease risk. [18] National Institutes of Health. Lower Sodium Could Reduce Blood Pressure in Most People. Dec. 5, 2023. Found on the internet at https://www.nih.gov/news-events/nih-research-matters/lower-sodium-could-reduce-blood-pressure-most-people The DASH diet has been found to significantly lower blood pressure and help with the long-term management of high blood pressure. [19] Onwuzo C, et al. DASH Diet: A Review of Its Scientifically Proven Hypertension Reduction and Health Benefits. Cureus. Sept. 4, 2023. Found on the internet at https://www.cureus.com/articles/186215-dash-diet-a-review-of-its-scientifically-proven-hyper  

Reducing processed foods means increasing whole, minimally processed foods. Since the DASH diet encourages more whole foods, it’s also been found to decrease LDL cholesterol The concentration of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is sometimes called “bad” cholesterol because its high concentrations are associated with increased risk of heart attack and stroke. levels, decrease the risk of heart failure, and decrease the risk of gout. [19] Onwuzo C, et al. DASH Diet: A Review of Its Scientifically Proven Hypertension Reduction and Health Benefits. Cureus. Sept. 4, 2023. Found on the internet at https://www.cureus.com/articles/186215-dash-diet-a-review-of-its-scientifically-proven-hyper  

When combined with exercise, a weight loss program, and regular counseling sessions with a health care provider, the DASH diet can improve blood pressure in people with hard-to-treat or “resistant” high blood pressure. [20] Blumenthal JA, et al. Effects of Lifestyle Modification on Patients With Resistant Hypertension. Results of the TRIUMPH Randomized Clinical Trial. Circulation. Sept. 27, 2021. Found on the internet at https://www.ahajournals.org/doi/10.1161/CIRCULATI  

Since there are many guidelines around daily servings, food choices, nutrient balance, and calorie limits, the DASH diet can be good for people who do better with planning structured diets. Meal preparation once or twice a week can be a good way to stay on track with a specific diet, but not everyone may have time for it. 

Why the DASH diet works for diabetes

Since the DASH diet recommends a fair amount of grain servings daily, it may result in a larger intake of carbohydrates, which can work against diabetes management. But the DASH diet’s emphasis on whole foods and limited sugars helps with blood sugar management, which is why it can still support people with diabetes. There’s limited but positive evidence supporting the DASH diet for both the management and prevention of type 2 diabetes and gestational diabetes. [21] Campbell AP. DASH Eating Plan: An Eating Pattern for Diabetes Management. Diabetes Spectrum. May 1, 2017. Found on the internet at https://diabetesjournals.org/spectrum/article/30/2/76/32278/DASH-Eating-Plan-An-Eating-Pattern-for-Diabetes The DASH diet has been found to decrease insulin resistance, inflammation, and glucose levels in the urine, which are markers that health care providers may monitor in people with diabetes.

The Acute Effects of a DASH Diet and Whole Food, Plant-Based Diet on Insulin Requirements and Related Cardiometabolic Markers in Individuals with Insulin-Treated Type 2 Diabetes. Diabetes Research and Clinical Practice. Jul. 5, 20  

In addition, a small study on older adults found that following a DASH diet combined with regular exercise for six months resulted in better insulin sensitivity and improved cognitive health. This study suggested possible benefits of the DASH diet combined with exercise on metabolic health (i.e., for diabetes management) and prevention of cognitive disorders like dementia.

Portfolio diet

Portfolio diet

Originally developed to lower “bad” cholesterol
Encourages plant-based foods with lots of fiber and healthy fats
Key features
  • Choose from plant-based food groups to add to your diet, also known as your “portfolio”
  • Choose to eat certain amounts of nuts, plant protein, fiber, plant sterols, and oils
  • Good for making incremental changes to your diet
Pros and cons of the Portfolio diet
Pros Can benefit people with high cholesterol and a high risk of heart disease Decreases risk of type 2 diabetes in postmenopausal women Allows for a gradual dietary change Cons Lack of research on its effects on people with diabetes Can encourage processed plant-based foods to reach some intake goals

How does the portfolio diet work?

The portfolio diet is a strategy developed to lower LDL cholesterol. It combines diet changes that have been found in research to lower cholesterol and gives people the option to add as many components as they’d like to their “portfolio,” or their diet. People “invest” as much or as little in each dietary pattern to build their cholesterol-lowering portfolio. Investing in each dietary pattern can reduce LDL cholesterol by 5%–10%, but if you invest in all of them, you can lower your LDL cholesterol by about 30%. For reference, cholesterol-lowering medications reduce cholesterol by 20%–60%. [24] Canadian Cardiovascular Society. The Portfolio Diet [PDF]. November 2023. Found on the internet at https://ccs.ca/wp-content/uploads/2023/11/Portfolio-Infographic-EN_7Nov2023.pdf

* Monounsaturated fatty acids

Our expert take

Unlike the DASH diet, which has more regimented recommendations for daily servings of food groups, the portfolio diet has more flexibility for people to gradually make dietary changes. Adding each dietary pattern to your diet slowly can support long-term changes that support a healthy lifestyle. In addition, the portfolio diet suggests lower daily intake goals when starting out so you can incorporate new foods into your diet without being overwhelmed. Lauren Kort, RD, in Miami, Florida, explained that small changes can still have positive effects on blood sugar. “Don’t let perfect be the enemy of good! You don’t have to completely change your diet to better control your blood sugar,” she said. 
Although the portfolio diet was developed to lower cholesterol, it has other heart and metabolic health benefits. One study showed that people who invested in more dietary patterns in the portfolio diet had lower risk of heart disease and stroke, better cholesterol, and lower inflammation. [25] Glenn AJ, et al. Portfolio Diet Score and Risk of Cardiovascular Disease: Findings From 3 Prospective Cohort Studies. Circulation. Oct. 25, 2023. Found on the internet at https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.123.065551

Heart health and diabetes

There’s a reason why lifestyle and diet changes for diabetes can also benefit heart health, and vice versa. People with diabetes are twice as likely to have heart disease or a stroke compared to people who don’t have diabetes.

In people with diabetes, high levels of blood sugar over a long period of time can damage the heart and blood vessels, leading to a higher risk of heart disease.

Recommendations for better heart health, such as exercise, weight management, and eating more whole foods and plant foods, can also benefit metabolic health in people with diabetes. [26] Centers for Disease Control and Prevention. Diabetes and Your Heart. Jun. 20, 2022. Found on the internet at https://www.cdc.gov/diabetes/library/features/diabetes-and-heart.html

Compared to the Mediterranean diet and DASH diets that encourage more whole, minimally processed foods, the portfolio diet suggests some processed foods to help people more easily achieve their daily intake goals. Convenience foods like veggie burgers and enriched foods like plant sterol-added margarine (a butter substitute) are examples of processed foods that can help someone consume more plant-based proteins and plant sterols, respectively. These are easy substitutes that someone with diabetes can make in place of eating more red meat or butter-containing foods. 

But it’s important to consider that processed foods end up containing other added ingredients, such as sodium, that may work against some health goals. “The best diets [for people with diabetes] starts with getting rid of highly processed foods,” said Gomer. Health care professionals like registered dietitians can help you weigh the benefits and drawbacks of the portfolio diet according to your specific health goals and lifestyle. 

Why the portfolio diet works for diabetes

Because the portfolio diet is aimed at supporting heart health, there aren’t many studies on it directly benefiting people with diabetes. But, in postmenopausal women, the portfolio diet was found to decrease the risk of type 2 diabetes. [27] Glenn AJ, et al. The Portfolio Diet and Incident Type 2 Diabetes: Findings From the Women’s Health Initiative Prospective Cohort Study. Diabetes Care. Sep. 26, 2022. Found on the internet at https://diabetesjournals.org/care/article/46/1/28/147679/Th  

Again, adding more plant foods like nuts and seeds, plant-based proteins, and fiber to the diet has been shown to help with managing diabetes. Plant-based diets have been found to help improve HbA1c and prevent type 2 diabetes, heart disease, and complications of diabetes. For example, plant-based diets can help reduce pain in patients with diabetic neuropathy Nerve damage as a complication of diabetes. . [28] McMacken M, et al. A Plant-Based Diet for the Prevention and Treatment of Type 2 Diabetes. Journal of Geriatric Cardiology. May 2017. Found on the internet at https://pubmed.ncbi.nlm.nih.gov/28630614/

Fiber is particularly encouraged for people with diabetes because of its benefits on blood sugar control. “Interestingly, fiber is found in a lot of carbohydrate foods like fruits, vegetables, and whole grains. Fiber slows down how our body digests carbohydrates,” said Kort. The viscous or “sticky” fiber in the portfolio diet is actually soluble fiber—a type of fiber that absorbs water and forms a gel that slows digestion. Soluble fiber found in foods like apples and okra can help control the rate at which carbohydrates are digested, which means a more controlled release of sugars into the bloodstream. [29] Centers for Disease Control and Prevention. Fiber: The Carb That Helps You Manage Diabetes. Jun. 20, 2022.

Both plans also include the Nutrisystem weight loss app, NuMi, which has challenges, prizes, expert tips, and recipes to help people keep on track with their weight loss goals. 

Nutrisystem meals come as frozen and non-frozen deliveries. People who get the “women’s” plan get three meals and a snack, and people who order the “men’s” plan get three meals and two snacks a day. According to the website, Nutrisystem D is designed to be low-fat, low-calorie, and portion-controlled to help people with diabetes lose weight. 

Nutrisystem can be convenient for busy people trying to manage their diabetes through weight loss, but the program may not be for everyone. The monthly cost can be expensive over time. Also, people who are taking medications for diabetes should consult a health care professional about the low-calorie diet to reduce risks of low blood sugar while on the diet.

Payment information 

Nutrisystem accepts payment through credit cards (Visa, Mastercard, American Express, and Discover), PayPal, Venmo, and Google Pay.

Special weight loss considerations for older adults

Before starting a weight loss program, you should always talk to your health care provider. Weight loss programs may not be the best option for everyone, and people with diabetes should be especially mindful of how their diet and lifestyle changes can impact their blood sugar. While there are certainly benefits to weight loss, these programs also pose unique potential risks for older adults.

Older adults are more at risk for experiencing bone and muscle loss due to calorie restrictions. Losing muscle mass and strength can also lead to other adverse effects like reduced physical function and overall quality of life. 

If you take insulin or other blood-sugar-controlling medications for diabetes, drastic changes to your diet can impact your blood sugar. If your blood sugar is too low, you can be at risk of fainting and complications of hypoglycemia. It is important to talk to your health care provider first so they can advise you on the best ways to reach your goals while accounting for your health history.

Weight loss programs can still be beneficial for older adults and people with diabetes. For example, studies have found that older adults participating in a dietary and exercise program improved overall quality of life and physical performance. William Cefalu, director of the NIDDK’s division of Diabetes, Endocrinology, and Metabolic Diseases, said that the most important factor in achieving remission from type 2 diabetes is weight loss [32] National Institute of Diabetes and Digestive and Kidney Diseases. Achieving Type 2 Diabetes Remission Through Weight Loss. Sept. 30, 2022. Found on the internet at https://www.niddk.nih.gov/health-information/professionals/diabetes-discoveries-practi . You can weigh the benefits and risks with your doctor or health care provider.

Frequently asked questions

The ADA doesn’t recommend any one diet for the management of type 2 diabetes but encourages nutrition changes that can support blood sugar control. [33] McKinney C. What Diet Does the American Diabetes Association (ADA) Recommend? The Johns Hopkins Patient Guide to Diabetes. Found on the internet at https://hopkinsdiabetesinfo.org/what-diet-does-the-american-diabetes-association-ada-recommend/ Every person can respond to an eating pattern differently, so it’s important to have professional guidance from a health care team that knows your health history. Some evidence shows that the Mediterranean diet, DASH diet, and the low-carb diet can support blood sugar control in type 2 diabetes.

People with diabetes should be conscious of the sugar, carbohydrate, fiber, protein, and fat content of their foods. Foods high in sugar and low in fiber, like sodas or candy, should be avoided in large amounts.

All foods should be eaten in moderation. The ADA’s Plate Method encourages people with diabetes to eat at least half their plate full of non-starchy vegetables such as broccoli, okra, green beans, and dark leafy greens.
