A level 3 diet plan often refers to a specific stage in dietary modifications designed for individuals with dysphagia, or swallowing difficulties, or as part of a weight-loss program like the South Beach Diet, or for managing conditions like stage 3 chronic kidney disease (CKD). Each of these contexts has distinct goals and approaches, focusing on food textures, macronutrient balance, and nutritional needs.
Dysphagia Level 3 Diet (Advanced)
The National Dysphagia Diet, published in 2002, developed universal terminology for texture-modified diets. Sometimes patients who have trouble chewing and/or swallowing whole foods need a special diet. The dysphagia advanced diet (level 3) is one of three levels of texture modification that is used. The International Dysphagia Diet Standardisation Initiative (IDDSI) also provides a framework for people with dysphagia. The diet has levels that rate drinks and foods on a thickness scale from 0 to 7. Foods from the National Dysphagia Diet level 3 diet are on IDDSI level 6.
Who Needs a Dysphagia Level 3 Diet?
Normally a speech and language pathologist will recommend a dysphagia advanced diet after evaluating a patient who has problems chewing or swallowing food. In some cases, medical tests are used to determine the best texture for a patient.
What Foods are Allowed?
Foods that are nearly normal textures are allowed on the dysphagia advanced diet, with the exception of crunchy, sticky, or very hard foods. The diet includes bite-sized foods that are moist. Foods that are allowed on dysphagia level 1 and level 2 diets also are allowed on the dysphagia advanced diet. It is important to include a variety of foods from all different food groups when providing a dysphagia advanced diet, including fruits, vegetables, grains, meats and meat substitutes, and dairy foods.
Food Textures for Dysphagia Advanced Diet (Dysphagia Level 3)
- Meat and meat substitutes: Thin-sliced, tender, or ground meats or poultry, well-moistened; fish; eggs (any preparation acceptable); yogurt (no nuts or coconut); casseroles with small chunks of tender or ground meat. Avoid tough or dry meats or poultry, dry fish or fish with bones, chunky peanut butter, yogurt with nuts or coconut.
- Bread: Well-moistened breads, biscuits, muffins, pancakes, waffles, etc (add jelly, margarine, and other toppings to moisten well). Avoid dry bread, toast, crackers, etc; tough, crusty breads, such as French bread.
- Cereals: All well-moistened cereals. Avoid coarse or dry cereals.
- Fruits: All canned and cooked fruits; soft, peeled, ripe fresh fruits, such as peaches, kiwi, mangos, cantaloupe, etc; soft berries with small seeds, such as strawberries. Avoid hard-to-chew fresh fruits, such as apples or pears; stringy, pulpy fruits, such as papaya, pineapple, or mango; fresh fruits with tough peels, such as grapes; prunes, apricots, and other dried fruits (unless cooked).
- Vegetables: All cooked, tender vegetables; shredded lettuce. Avoid all raw vegetables, except shredded lettuce; cooked corn; rubbery cooked vegetables.
- Potatoes and starches: All, including rice and tender fried potatoes. Avoid tough or crisp fried potatoes.
- Desserts: All desserts, except those on the avoid list. Avoid dry cakes or cookies that are chewy; anything with nuts, seeds, dry fruits, coconut, and pineapple.
- Beverages: Any beverage of recommended consistency.
Liquids
Possibly. For some patients, regular liquids are OK. However, depending on your condition, you might need to have thickened liquids, so you can swallow them safely. Talk to your speech and language pathologist to learn more.

Liquids can be thickened, if needed, with thickeners, flour, cornstarch, or potato flakes. Foods that are liquid at room temperature should also be thickened. Thin liquids flow quickly. These liquids take little or no effort to drink. Examples include water, non-fat milk, no-pulp juice, coffee, tea, and soft drinks. Slightly thick liquids are thicker than water but still flow through a bottle's nipple. A little more effort is needed to drink these liquids. Nectar-thick liquids have the same thickness as vegetable juices and milkshakes. It should take some effort to drink the liquid through a straw. Honey-thick liquids should be difficult to drink through a straw. Pudding-thick liquids need to be eaten with a spoon. You should not be able to drink them through a straw.
Important Considerations for Dysphagia Diets
- Preventing Aspiration: When you have dysphagia, you are at risk for aspiration. Aspiration is food or liquid entering the lungs. It can cause pneumonia and other problems. A dysphagia diet can help prevent aspiration.
- Oral Care: After meals, it’s important to do correct oral care. The SLP can give you instructions for your teeth or dentures. Make sure to not swallow any water during your oral care routine.
- Hydration: While on a dysphagia diet, you may have trouble taking in enough fluid. This can cause dehydration, which can lead to serious health problems. Talk with your care team about how you can help prevent this.
South Beach Diet: Phase 3
The South Beach Diet is a popular commercial weight-loss diet. Heart doctor Arthur Agatston, M.D., created the diet. He named it after a stylish part of Miami. The South Beach Diet limits some types of foods that have nutrients called carbohydrates. These also are known as carbs. Carbs are a key source of calories that give the body energy. The South Beach Diet doesn't tightly limit all foods that have carbs. It just limits the ones that are more likely to cause weight gain. Another version of the South Beach Diet places strict limits on carbs. It's called the keto-friendly South Beach Diet. Keto is short for ketogenic. The purpose of the South Beach Diet is to change the overall balance of the foods you eat. This change may help you lose weight and lead a healthy lifestyle.
Phase 3 of the South Beach Diet aims to help you eat healthy for life. You focus on eating foods with complex carbs, lean protein and healthy fats. But you can eat all types of foods.
Key Principles of the South Beach Diet
- Focus on Complex Carbs: The South Beach Diet features foods that have lean protein, healthy fats and some carbs. The diet mainly includes healthy carbs that give the body steady energy. These are called complex carbs. The body digests complex carbs slowly. Then the carbs turn into sugar that slowly moves into the bloodstream. This sugar is called glucose.
- Limit Simple Carbs: The South Beach Diet limits carbs that give the body a short burst of energy. These are called simple carbs. They tend to have less nutrition than complex carbs. And too many simple carbs can lead to weight gain.
- Healthy Fats: The South Beach Diet also features foods that have healthy fats. These include plant-based oils, nuts and oily fish. The diet limits sources of saturated fat such as red meat and butter.
- Lean Protein: The South Beach Diet features foods that have lean protein as well.
- Regular Exercise: The South Beach Diet recommends regular exercise as an important part of your lifestyle. It suggests activities such as walking and strength training.
Sample Meals
- Breakfast: Breakfast might be an omelet with smoked salmon or baked eggs with spinach and ham.
- Lunch: Lunch might be a vegetable salad with scallops or shrimp.
- Dinner: Dinner may feature grilled tuna or pork.
- Dessert: The diet recommends that you have a dessert that's not sugary after dinner. For instance, you could try sugar-free gelatin.
- Snacks: You can enjoy snacks during the day too.
Stage 3 Chronic Kidney Disease (CKD) Diet
In stage 3 chronic kidney disease (CKD), the kidneys still function sufficiently to remove fluid, potassium potassium and a moderate amount of waste.
Key Dietary Recommendations for Stage 3 CKD
- Calories: Adequate calories can either prevent weight loss if you’re at a desirable weight or provide extra calories if you are underweight. Weigh yourself often and keep track to see if you need additional or fewer calories.
- Fats: If you have cardiovascular disease or your blood cholesterol is high, unhealthy fats-such as saturated fats and trans-fats-should be replaced by poly- and monounsaturated fats from vegetable oil, canola oil and olive oil.
- Fluid: Fluid is not restricted in stage 3 CKD unless you experience fluid retention. Sudden weight gain, shortness of breath, swelling in the feet, hands and face and high blood pressure are signs of fluid retention.
- Potassium: Usually, potassium is not restricted in stage 3 CKD unless lab tests show potassium is too high. Your doctor may make medication changes or prescribe a low-potassium diet.
- Protein: Know your recommended daily intake of protein. The recommendation for protein intake in stage 3 is 0.8 g/kg body weight, the same recommendation for a healthy 150-pound adult.
- Sodium: Limiting salt and high-sodium foods reduces hypertension, assists blood pressure medications to work more effectively and treats fluid retention. The sodium recommendation for stage 3 CKD is 1,000 to 4,000 mg/day.
