The glucose gap
2025 State of Wellness report
In 2025, Britons are more determined than ever to listen to their bodies.
They are trusting physical signals, embracing wearable technology, and seeking personalised data. Yet they’re missing a powerful metric that could transform their health.
Our research reveals something remarkable: Most Britons don’t know how glucose shapes their daily health.
But a growing community is discovering its power. Through continuous glucose monitors (CGMs), they’re uncovering surprises about their bodies and transforming “Ah-ha” moments into real change.
Some think glucose tracking is just for managing diabetes. Others see it as a tool for biohackers.
What sets CGM users apart is what they are achieving: the healthy changes so many Britons want for themselves.
We are thrilled to share these findings with you and start an urgent conversation about bridging the gap between how Britons feel and what their bodies are telling them.
The missing link in metabolic health
Metabolic challenges
1 out of 3 Britons lives with prediabetes, while 2 in 3 live with excess weight.
Goals are in for 2025
Over 9 out of 10 Britons are setting health goals this year.
The glucose gap
But 4 of 5 Britons don't see glucose as relevant to their health goals.
Surprising CGM insights
69% of people using Lingo CGMs found "healthy" foods had a surprising impact on their glucose.
New insights, new habits
91% of Lingo members are building a new habit based on what they learned.
Reducing sugar
37% of Britons want to eat less sugar this year. 46% of Lingo members are making this change.
What are Lingo members learning?
86%
of self-described "glucose experts" had at least one surprising discovery after using a CGM.
69%
say a "healthy" food caused a larger-than-expected glucose spike.
1 in 3
found stress affected their glucose more than expected.
55%
are cutting back on carbs. Nationwide, 20% of Britons plan to eat fewer carbs this year.
77%
of those who use Lingo to improve their focus say it's effective.
3 in 4
agree glucose tracking has been effective in helping them achieve their health goals.
The big picture
Glucose is one of the primary sources of energy for the body, fueling everything from your brain to your muscles. When this process runs smoothly, people are metabolically healthy — but some people don't tolerate rises in glucose as well as others.
1 in 3 Britons live with prediabetes, while 2 in 3 live with excess weight. Suboptimal metabolic health could increase the risk of serious disease in the long run.
Lingo members share their learnings
- "If I ate right before bed, my glucose spiked and dropped all night. No snack before bed, and glucose was steady all night."
- "Walking after meals stopped a large glucose spike, even from high carb food sources."
- "I was really able to play around to optimise foods I commonly eat."
