For people living with prediabetes or type 2 diabetes, eating well can significantly affect glucose levels and overall health. A sustainable meal plan fuels the body with a variety of nutrients while also making eating more enjoyable. And eating well is not an all-or-nothing proposition. Every small positive change is a win.
With a little practice and support, you can develop a meal plan that works for you. Here are the five pillars of nutrition for optimal glucose health. 

Pillar #1: What to eat
According to the American Heart Association and the American Diabetes Association, no fixed diet defines what people with type 2 diabetes or prediabetes should eat. Rather, a more personalized approach, based on one’s glucose pattern and food preference, is recommended.
Nourishing your body with a range of nutrients—like fiber-rich carbs, lean meats or plant-based proteins, and heart-healthy fats—can help slow down carbohydrate breakdown into sugar, which can improve your post-meal glucose trends. While a sustainable meal plan should offer plenty of food choices, it’s best to avoid sugary drinks and limit highly processed foods like bakery items, granola bars, and processed meats.

Pillar #2: How much to eat

Eating out can be tricky for glucose health since restaurant portions are often two to three times the recommended serving size. Reviewing the menu ahead of time and using the plate method, even at a restaurant, can help you enjoy your meal while managing your glucose levels.

Pillar #3: When to eat

While what and how much to eat often steal the spotlight in meal planning, the timing of meals and snacks is just as important. Ever gone long hours without eating and felt “hangry”? Or snacked through meetings only to feel full right before lunch? These are signs that your eating schedule might need adjusting.
Take a look at your daily routines and consider what times would work best for consistent meals. Then, pay attention to hunger and fullness cues, as well as glucose levels throughout the day, to help determine if your eating schedule is providing the right amount of energy.
Meal timing can significantly impact what and how much you eat, ultimately affecting post-meal glucose trends. Consider focusing on this essential aspect of nutrition as a starting point—it might just make following the first two pillars easier.

Pillar #4: Where to eat

Location, location, location… Choose a spot where mindful eating is possible—like sitting at the table and focusing on each bite. Engage all your senses: smell, taste, texture, and appearance. This practice can help curb your appetite and tune you into hunger cues, so you know when to stop.
Think about how easily a bucket of popcorn disappears at the movies—that’s the effect of being in a place where your brain is preoccupied with the movie rather than attuned to your body’s natural hunger signals.

Pillar #5: Why we eat
Food habits often include emotional eating, comfort eating, and eating when not truly hungry. If you relate to these non-hunger eating patterns, a dietitian can help pinpoint areas where glucose levels might be affected by these habits. They can also guide you in finding non-food rewards or activities as satisfying replacements.

Listen to your body

We all have days when we don’t feel our best. Listening to your body can be as simple as noticing when you're tired and allowing yourself to rest, or choosing physical activities that bring you joy. It might also mean recognizing challenges in managing glucose patterns, even with healthy eating. As always, don’t hesitate to reach out to your healthcare provider for guidance and support.
