When I first started using a CGM, I thought I was mainly going to learn which foods raised my blood sugar.
I did learn that.
But I also started seeing a bigger picture.
My CGM has helped me connect the dots between food, movement, sleep, stress, fiber, sweeteners, and the everyday choices that may either help my numbers or make them harder to manage.
The CGM I am currently using is the Stelo CGM. I like having real-time feedback because it helps me see how my own body responds instead of guessing.
This is not a “do exactly what I do” post. Everyone responds differently. But I thought it might be helpful to share the CGM weight loss strategies I am personally trying as I work on improving my blood sugar spikes, average glucose, and weight.

Why I’m Looking Beyond Just Food
Food matters. There is no question about that.
But my continuous glucose monitor has made me realize that blood sugar is not only about one meal or one snack. The same food can raise my glucose levels differently depending on my sleep, stress, movement, timing, and what I ate with it.
Did I move after eating? Did I sleep well? Was I stressed? Did I eat enough protein or fiber? Was I already running higher before the meal?
Those are the kinds of questions I was not asking before.
That is where my continuous glucose monitor changed things for me. Instead of guessing, I can look at my own glucose data and start connecting my choices with what is happening in my body.
I use Stelo, which is an over-the-counter continuous glucose monitor (CGM) for adults 18 and older who do not use insulin. The Food and Drug Administration says Stelo is intended for adults with diabetes who are not using insulin, as well as people without diabetes who want to better understand how diet and exercise may affect blood sugar levels. The Food and Drug Administration also notes that people should not make medical decisions based only on device readings without talking with a healthcare provider.
That point matters to me. I am not using my continuous glucose monitor to diagnose myself or make medical decisions on my own. I am using it to notice how food, movement, sleep, stress, and daily habits are affecting my glucose patterns.
I think a continuous glucose monitor can make weight loss feel less like guesswork. The scale may show whether my weight changed, but my glucose data helps me see how my meals, movement, sleep, stress, and habits are affecting my glucose patterns day by day.
Eating Lower Carb, But Not Keto
One food change I am working on is eating lower carb, but I am not trying to do keto.
For me, that means I am paying more attention to the amount and type of carbohydrates I eat. I am trying to choose meals that feel more balanced and do not send my blood sugar as high.
That might mean fewer refined carbs, smaller portions of certain foods, more protein, more fiber, and watching what happens on my CGM after meals.
I am not trying to remove every carb from my life. I am trying to notice which carbs, portions, and meal combinations seem to work better for me.
The CDC notes that eating carbohydrates with foods that have protein, fat, or fiber can slow how quickly blood sugar rises. I am paying more attention to the whole meal instead of only looking at one number on a label.
Protein Snacks I’m Using
I am also trying to be more intentional with snacks.
One option I am currently using is IQBAR protein bars. I like having a protein option that is lower in sugar and does not rely on sugar alcohols.
That matters to me because a lot of bars that look “healthy” or “low carb” on the front of the package often have ingredients I personally prefer to avoid.
It is important to read the label for yourself. Ingredients and formulas can change, and everyone’s body responds differently.
Sweeteners and Sugar Alcohols
I have also been paying closer attention to sweeteners.
Right now, I use:
Honey with monk fruit and allulose
One thing I am personally trying to avoid is sugar alcohols.
That means I read ingredient labels carefully, because a lot of “sugar-free,” “low sugar,” and “keto-friendly” products contain sugar alcohols. Some common sugar alcohols include erythritol, xylitol, sorbitol, maltitol, mannitol, lactitol, and isomalt.
Erythritol is the one I am most cautious about right now.
Some research has raised concerns about erythritol and cardiovascular risk. A 2023 Nature Medicine study found that erythritol was associated with major adverse cardiovascular event risk and enhanced thrombosis. A 2024 study also found that consuming erythritol, but not glucose, increased platelet reactivity in healthy volunteers.
That does not mean the research proves erythritol directly causes heart attacks or strokes. Association is not the same thing as proof of cause and effect. But for me, it is enough of a concern that I prefer to avoid erythritol when I can, especially since it shows up in so many products that look healthy on the front of the package.
Lower-Carb Dessert Ideas
Sweets are one of my biggest downfalls, so I try to find dessert ideas that feel realistic without sending me completely off track.
One resource I have been using is the Glucose Goddess cookbook. I have used it mostly for dessert ideas because it includes several lower-carb recipes that are easy to prepare, actually taste good, and don’t spike my glucose.
I am not saying every recipe will work the same way for everyone. Even “healthier” desserts can affect people differently. That is one reason I like using a CGM. I can try something, watch my own glucose response, and decide whether it is something I want to make again.
This is not about never having sweets again. It is about finding better options so I do not feel stuck between giving them up completely or eating something that sends my glucose level higher than I want.
Adding More Fiber
Fiber is another area I am paying more attention to.
I am trying to eat more vegetables, some fruits, and some whole grains. But even with that, it can still be difficult to get enough fiber every day.
That is one reason I’ve added basil seeds for fiber.
For me, this is not about forcing a huge fiber increase overnight. It is more about finding small ways to support fullness, digestion, and steadier meals.
The CDC notes that fiber can help with blood sugar control and weight management, especially for people with diabetes or prediabetes, because the body does not absorb and break down fiber the same way it does other carbohydrates.
That is one reason I am trying to pay more attention to fiber along with carbs, instead of only looking at total carbohydrate numbers.
Supplements I’m Trying
I am also trying a few supplements as part of my overall routine.
The first is Best Naturals Liposomal Berberine. Berberine is something I have been curious about because it is often discussed in relation to blood sugar, cholesterol, and metabolic health.
NCCIH says there is some evidence that berberine may have a modest effect on lowering blood glucose levels in people with type 2 diabetes and may reduce cholesterol levels, but it can also cause side effects and interact with medications.
The second supplement I am trying is Ceylon cinnamon.
I have heard for a long time that Ceylon cinnamon may be a better cinnamon option than regular cassia cinnamon, so that is the one I am choosing.
NCCIH notes that cinnamon products are often promoted for diabetes and weight loss, but the research is not strong enough to treat cinnamon like a guaranteed blood sugar solution.
This is where I think caution matters. Supplements can interact with medications. They are not automatically safe just because they are natural. If you take medication, have diabetes, have liver disease, are pregnant, are breastfeeding, or have any medical condition, this is definitely something to discuss with your healthcare provider first.
Movement Is Still a Big Piece
Movement has been one of the biggest surprises for me.
I expected food to be the main thing I noticed on my CGM, but movement has been a major part of the picture too.
Sometimes a short walk after a meal helps. Sometimes using a simple piece of equipment at home makes it easier to get moving when I do not feel like doing a full workout.
I wrote more about that in my post on what my CGM taught me about movement and weight loss.
A few simple movement tools I like having available are:
These are not complicated. That is what I like about them.
The easier something is to use, the more likely I am to actually use it.
Sleep Matters Too
Sleep is another part of the puzzle I am paying more attention to.
When I do not sleep well, everything feels harder the next day — cravings, energy, motivation, and sometimes even my blood sugar patterns.
One simple thing I am using is chamomile tea.
I am not saying chamomile tea is a sleep cure. For me, it is more of a calming evening habit. I also like that it gives me something warm in the evening that does not feel like another snack.
My Main Takeaway So Far
The biggest thing I am learning is that blood sugar improvement is not just one thing.
It is not just carbs. It is not just supplements. It is not just walking. It is not just sleep.
For me, it is more like building a routine I can actually pay attention to and adjust.
Right now, I am experimenting with lower-carb meals, sweeteners that work better for me, protein snacks, more fiber, lower-carb dessert ideas, simple movement, better sleep habits, stress support, and a few supplements I wanted to try.
Will all of these things work for everyone? No.
But that is exactly why I like using a CGM. It gives me feedback that is personal. It helps me stop guessing and start noticing what my own body seems to respond to.
If you are using a CGM for weight loss, I’d love to know what has surprised you most so far. Was it a certain food, a meal combination, stress, sleep, movement, or something completely unexpected?
And if you are not using one yet, what would you want a CGM to help you figure out first?
