7-Day No-Sugar High-Fiber Meal Plan for Insulin Resistance, Created by a Dietitian

According to 2021 data from the National Health and Nutrition Examination Survey, 40% of people between 18 to 44 in the U.S. have insulin resistance. Insulin resistance, sometimes called impaired insulin sensitivity, is a precursor to several health conditions, including diabetes and prediabetes, obesity and nonalcoholic fatty liver disease, per StatPearls. 

Insulin is a hormone released by the pancreas in response to a rise in blood sugar, which is a natural response when the food you eat is broken down into a type of sugar called glucose. 

When things are working smoothly, insulin helps move blood sugars into the cells for energy, which returns circulating blood sugar to normal baseline levels. Over time, the body can develop a tolerance to insulin, meaning the blood sugars don’t respond as well despite the body pumping out high insulin levels, which results in elevated blood sugar levels, per the American Diabetes Association. 

While there isn’t a singular cause of insulin resistance, the Centers for Disease Control and Prevention cites factors that can increase risk, including a family history of type 2 diabetes, lack of physical activity and obesity. And because added sugars are so prevalent in food and many people consume more than they realize, we opted to exclude them from this plan. Instead, we opted to focus on nutrients that are shown to improve blood sugars—like fiber and protein. 

In this plan, you’ll find at least 35 grams of fiber daily and a minimum of 70 grams of protein to help improve insulin resistance. According to the National Institutes of Health, weight loss, even in small amounts, can help improve blood sugar levels and reduce the risk of developing type 2 diabetes. 

To promote weight loss, we set this plan at 1,500 calories per day, a level where many people lose weight. We also included modifications for 1,200 and 2,000 calories per day for those with other calorie needs. As always, this meal plan is meant to serve as a framework for a nutritious eating plan. Follow your hunger cues and listen to your body. You know it best!

Strategies to Improve Insulin Resistance:

1. Increase Fiber: Fiber is linked to many health benefits, including protecting the heart and promoting a healthy gut. Additionally, it helps stabilize blood sugar levels and keeps you full for longer by slowing down digestion.
2. Exercise Frequently: The CDC and the ADA cite increasing physical activity as one of the most important and beneficial steps for improving insulin resistance.
3. Ensure Regular Meals: Eating regular meals and snacks, ideally with a good source of fiber and protein, helps promote stable blood sugars and prevents eating too much. 
4. Boost Protein: In addition to helping you build muscle and other body functions, protein also slows down digestion and improves satiety. Pairing protein-rich foods with those higher in carbohydrates helps temper the blood sugar response and stabilize levels. 
5. Reduce Added Sugars: Though added sugar can be included in moderation, stick to the American Heart Association's recommended daily max of 9 teaspoons of added sugar for men and 6 for women. 

High-Fiber Foods to Focus On: 

Some examples include:

• Whole grains: bulgur, oats, teff, whole wheat, brown rice, quinoa, buckwheat and farro
• Beans and lentils 
• Vegetables: Brussels sprouts, kale, corn, broccoli, cauliflower, collards, beets, sweet potato, leafy greens and carrots
• Fruits (especially fruit with skin and seeds): berries, pears, apples, oranges, clementine, fig, kiwi and avocado
• Nuts (including natural nut butters with no sugar added): walnuts, pistachios, pecans, almonds, cashews
• Seeds: sunflower, pumpkin, chia and flax
