Plain-English Summary
CGM feedback can support behavior change in some contexts. The magnitude and relevance depend on population, intervention design, and what decisions the user changes.

How the study framework works ->Key Findings
- CGM feedback can support behavior change in some contexts.
- The magnitude and relevance depend on population, intervention design, and what decisions the user changes.
Limitations
- Heterogeneous populations and interventions.
- CGM feedback is not automatically beneficial for every healthy consumer.

CGMs for Non-Diabetics: Metabolic Radar or Anxiety Subscription?
Continuous glucose monitors are moving from diabetes care into consumer metabolic self-tracking. That can help some people understand meals, sleep, stress, exercise, and risk. It can also turn normal physiology into false precision, food fear, and subscription anxiety.

sleep: Longitudinal commercial wearable sleep data can reveal associations between
Longitudinal commercial wearable sleep data can reveal associations between sleep duration, irregularity, sleep stages, and chronic disease incidence, but wearable sleep scores should not be treated as clinical-grade diagnosis.
weight loss: Sustained fat loss requires net energy deficit, but the
Sustained fat loss requires net energy deficit, but the appetite, expenditure, adaptation, and maintenance systems that shape that deficit are biologically regulated.
semaglutide: Semaglutide improved kidney outcomes in FLOW participants with type
Semaglutide improved kidney outcomes in FLOW participants with type 2 diabetes and chronic kidney disease.
weight loss: Calories describe the accounting of tissue-energy change, but they
Calories describe the accounting of tissue-energy change, but they do not explain all biological friction around appetite, expenditure, adaptation, food environment, hormones, sleep, lean mass, and maintenance.
vegan diet: Vegetarian and vegan diets can lower LDL-C and apoB
Vegetarian and vegan diets can lower LDL-C and apoB on average in randomized trials, especially when they improve saturated-fat and fiber patterns.
carnivore diet: Strict carnivore and zero-plant eating conflict with current U.S.
Strict carnivore and zero-plant eating conflict with current U.S. dietary guidance emphasizing whole nutrient-dense foods including vegetables, fruits, healthy fats, dairy, protein foods, and whole grains.
