Most of us grabbed the pink, blue, green, or “keto” packets at some point thinking, “Well… at least it’s not sugar.” I did too.
But newer research is making that story a lot messier. In 2023, the World Health Organization actually came out and said non‑sugar sweeteners (diet soda sweeteners like sucralose, aspartame, saccharin, acesulfame‑K, etc.) should not be used as a long‑term strategy for weight loss or disease prevention. When they looked at the data, they didn’t see lasting changes in body fat, and they saw links with higher risk of diabetes, heart disease, and even overall mortality in long‑term observational studies.
Some sweeteners, especially sucralose and saccharin, also seem to throw off blood sugar control and nudge the gut microbiome in the wrong direction. One trial found sucralose made people about 18% less insulin‑sensitive. Another saw higher fasting insulin after regular sucralose use. That’s the opposite of what most of us are hoping for.
And erythritol—the one in a lot of “keto” products—has been linked with a higher risk of heart attack and stroke in people who were already at risk, with blood levels that seem to make platelets more likely to clot. Not a great combo if you’re already watching your heart.
What are some better tools?
Sweeteners that can actually do something for you
Xylitol – the tooth helper
Xylitol is a sweetener that cavity‑causing bacteria can’t use the same way they use sugar. Studies on xylitol gum, candies, and lozenges show fewer cavities and lower levels of the bacteria that drive tooth decay when people use it regularly. It also has a very low impact on blood sugar and insulin.
I mostly think of xylitol as a dental tool: gum or mints after meals, especially for people who are prone to cavities or have dry mouth. (Important side note: it is extremely toxic to dogs, so it has to be stored like medicine if you have pets at home.)
Stevia – a calmer option for blood sugar
Stevia is one of the few non‑caloric sweeteners that actually has some data showing it can lower blood sugar a bit, especially in people with higher BMI or diabetes, without raising insulin or HbA1c. Some studies suggest it may even help with insulin sensitivity.
In real life, I use Xylitol and clean stevia (no funky fillers) when someone truly needs a zero‑sugar option—like swapping a daily soda for sparkling water with stevia and lime.
Monk fruit – sweetness with antioxidant support
Monk fruit gets its sweetness from mogrosides, which in lab and animal studies act as antioxidants and anti‑inflammatory compounds. Early research points to benefits for oxidative stress, inflammation, and even fat metabolism.
I reach for monk fruit when we’re working on inflammation or gut healing and the person doesn’t love stevia’s aftertaste.
Allulose – the “rare sugar” with metabolic perks
Allulose looks like sugar on paper but your body barely uses it for calories. Studies show it has little effect on blood glucose, and some research suggests it can increase fat burning after meals and help protect against fatty liver and insulin resistance in animal models and early human work.
I see allulose as a “bridge” sweetener for occasional treats while we’re working on deeper metabolic healing—not something to pour into everything, but a smarter choice than regular sugar or big doses of erythritol for many clients.
On top of these, there’s still room for small, intentional amounts of real‑food sweeteners—fruit, dates, raw honey, maple—used inside a balanced meal with protein, healthy fats, and fiber so you’re not on the blood sugar roller coaster.
My goal with clients isn’t to find the perfect loophole that lets us keep everything ultra‑sweet; it’s to gently retrain the body to feel good with less sweetness, while using tools that actually support teeth, blood sugar, and inflammation along the way.
If you’re curious which of these might fit your situation (insulin resistance, gut issues, heart risk, or just wanting to get off diet drinks), send me a DM and I’ll share how I work through this step‑by‑step in coaching.
