When I first started using a continuous glucose monitor (CGM), I paid a lot of attention to the number on the screen.
Now I’m learning to pay more attention to the meal behind the number.
What did I eat?
How much did I eat?
Did I eat carbs by themselves?
Did I include protein, fiber, or healthy fat?
How high did my glucose go?
How long did it stay up?
I’m not trying to avoid every glucose rise. Food is supposed to raise blood sugar, especially when a meal includes carbohydrates. What I’m watching for are the meals that send my glucose higher than expected or keep it elevated longer than I would like.
One thing that helps me is tracking what I eat. I use the Stelo continuous glucose monitor, and I like that I can track food directly in the app. That makes it easier to look back and connect a meal with what happened to my glucose afterward.
Here are some of the meal tweaks I’m using now, along with a few I’m still experimenting with.

1. Add Protein to Carb-Heavy Meals
One of the first things I noticed is that carbs by themselves can hit harder.
For me, a meal with mostly bread, crackers, cereal, rice, or something sweet is more likely to send my glucose up faster. But when I add protein, the response is often slower and lower.
That might mean eggs, chicken, Greek yogurt, cottage cheese, tuna, turkey, beans, or another protein source.
This does not mean I never eat carbs. It means I’m trying not to eat a mostly-carb meal and then act surprised when my glucose jumps.
Always ask yourself:
What can I add to this meal to make it work better?
2. Include Healthy Fat With the Meal
This has been one of the more helpful things I’ve noticed.
My glucose spikes often seem lower when I include a healthy fat with my meal. For me, avocado has been one of the best examples.
If I eat a meal with carbs, protein, fiber, and avocado, my glucose response often looks is usually better than when I eat the carbs without the fat.
That does not mean I add a large amount of fat to every meal. Portions still matter, especially when weight loss is the goal. But healthy fat is something I pay attention to.
A few examples:
- Eggs with avocado and whole grain toast
- Chicken salad with avocado
- Greek yogurt with berries and nuts
- Apple slices with peanut butter
- Vegetables with hummus
For me, avocado has been one of the easiest ways to make a meal more filling and less likely to send my numbers on a roller coaster.
3. Bring in More Fiber
Fiber is another piece I’m trying to be more intentional about.
I’m working on eating more vegetables, some fruits, beans, basil seeds, and some whole grains. These foods can help make meals more filling, and they may also help slow down how quickly glucose rises after eating.
One easy option I’ve used is basil seeds for fiber. They thicken when soaked, almost like chia seeds, and can be stirred into yogurt, drinks, or certain recipes.
One habit I’ve added before meals is asking myself, “Can I add something more fiber to this meal?”
That might be vegetables, berries, beans, lentils, basil seeds, chia seeds, or a higher-fiber bread or wrap.
4. Pay Close Attention to “Healthy” Carbs
Never assume that just because a carb is healthy, your blood sugar will respond the way you expect.
Everyone can react differently, and even your own response may change depending on the portion, what you eat with it, the time of day, and what else is going on.
Oatmeal, whole grain bread, fruit, brown rice, sweet potatoes, and beans are all healthy carbs. But that does not mean my blood sugar responds the same way every time I eat them.
If I see a larger increase than expected, I look closer.
I ask myself:
How much did I eat?
Did I eat it by itself?
Did I have protein with it?
Did I include fiber or healthy fat?
What time of day did I eat it?
Did I move afterward, or did I sit for a long time?
The time of day can matter too. A food that works better for me at lunch may not work the same way at breakfast or late at night.
Instead of removing a healthy carb right away, I experiment. Maybe I need a smaller portion. Maybe I need to eat it with eggs, chicken, Greek yogurt, avocado, or vegetables. Maybe I need to eat it at a different time of day.
This is one of the primary reasons I like using a continuous glucose monitor. It takes the guess work out of how my body is responding.
5. Try Eating Protein, Fat, or Vegetables Before Starches
I’ve also been experimenting with food order.
Instead of starting with bread, rice, potatoes, or something sweet, I try to start the meal with protein, vegetables, or avocado first.
For example:
- Eggs and avocado before toast
- Salad or vegetables before pasta
- Chicken before rice
- Greek yogurt before fruit or granola
I don’t treat this like a strict rule. I just see it as another experiment.
If I can make one small change and my glucose rise is lower or shorter, I count that as a win.
6. Compare Breakfast Choices Carefully
Breakfast has been one of the most challenging areas for me.
I love pancakes, French toast, doughnuts, and pastries. I really do. But my continuous glucose monitor has shown me that those foods send my glucose higher than I want.
So I’ve had to change how I handle those foods.
Most of the time now, I skip those foods.
One reason is that I’ve noticed if I start the day with something that spikes my blood sugar higher than normal my blood sugar seems to struggle more the rest of the day.
So I look for options that work better for me, like eggs scrambled with cottage cheese and vegetables, Greek yogurt with blueberries or strawberries, or a smoothie with Greek yogurt, fruit and protein powder.
I’m not saying I’ll never eat pancakes or French toast again. But I am learning that breakfast sets the tone for my day more than I realized.
For me, starting with more protein and less sugar usually gives me a better chance of keeping my glucose steadier.
7. Notice the Height and Length of the Spike
I used to think mostly about whether my glucose went up.
Now I pay more attention to two things:
How high did it go?
How long did it stay there?
For my own notes, I often flag a rise of around 30 points or more so I can look closer at what happened. But I don’t panic over one number.
I want to know the story behind it.
Was the meal mostly carbs?
Did I skip protein?
Did I forget healthy fat?
Was the portion larger than usual?
Did I eat at a different time of day?
Did I sit for a long time afterward?
That helps me decide what to change the next time I eat a similar meal.
Final Thoughts
Using a continuous glucose monitor for weight loss has made me more aware of my meals.
I’ve learned that protein, fiber, healthy fat, portions, food order, and timing all make a difference. And for me, avocado has become one of the most helpful healthy fats to include with meals.
Your results may look different from mine. That’s why you need to test your own meals and see what actually works for your body.
If you are using a continuous glucose monitor, try picking one meal this week and making one small change. Add protein. Add avocado. Add vegetables. Change the portion. Track what you ate. Then watch what happens.
The goal is to learn which meals help your glucose rise less sharply and come back down sooner.
Have you noticed a meal combination that seems to work better for your blood sugar? I’d love to hear what you’re finding.
