Doing intense exercise (like running) is more efficient than moderate exercise (like brisk walking) for lowering your chances of getting type 2 diabetes. For every minute of intense exercise, you need about nine minutes of moderate exercise to get the same benefit.
See the scientific wording
Approximately 9.4 minutes of moderate-intensity physical activity is required to achieve the same reduction in type 2 diabetes risk as 1 minute of vigorous-intensity physical activity.

What the research says
4 studies reviewedSupporting (2)
Device-measured physical activity and type 2 diabetes mellitus risk
Cohort StudyHuman2023
The study shows that intense exercise is better for preventing diabetes than moderate exercise if you burn the same calories, but it doesn't say exactly how many minutes of each are equal.
Cohort StudyHuman2025
The study found that for type 2 diabetes, 1 minute of vigorous exercise gives the same benefit as about 9.4 minutes of moderate exercise, which matches the claim exactly.

Walking vs running for hypertension, cholesterol, & diabetes risk reduction
Cohort StudyHuman2013
The study shows that walking and running are equally good for your health if you burn the same amount of energy, but it doesn't tell us how many minutes of each are needed, so we can't say that 1 minute of running is worth 9.4 minutes of walking.
Randomized Controlled TrialHuman2024
The study found that doing moderate exercise was just as good, or even better, for blood sugar than doing intense exercise, so intense exercise is not as efficient as the claim says.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When you exercise very hard, your muscles need fast energy. They pull sugar from your blood into the muscle cells at a much faster rate than during easy exercise. Also, hard exercise uses more muscle fibers, so more of your body helps in taking up sugar. Over time, this makes your muscles more sensitive to insulin, keeping blood sugar levels stable and reducing the risk of diabetes.

Mechanism
4 studiesHard exercise is more efficient at preventing diabetes because it makes your muscles absorb sugar from the blood much faster than easy exercise. Over time, that improves your body's ability to handle sugar, so you're less likely to develop diabetes.
When you exercise very hard, your muscles need fast energy. They pull sugar from your blood into the muscle cells at a much faster rate than during easy exercise. Also, hard exercise uses more muscle fibers, so more of your body helps in taking up sugar. Over time, this makes your muscles more sensitive to insulin, keeping blood sugar levels stable and reducing the risk of diabetes.
High-intensity muscle contractions rapidly deplete phosphocreatine and glycogen stores, leading to a rise in the cellular AMP/ADP ratio and activation of AMPK.
AMPK signaling promotes the translocation of GLUT4 glucose transporters to the muscle cell membrane, increasing glucose uptake from the blood.
Vigorous activity recruits a larger proportion of fast-twitch muscle fibers, which have a higher capacity for glucose uptake and are more responsive to metabolic signals, amplifying the total glucose disposal.
Immediately following exercise, muscle insulin sensitivity is enhanced, and this effect persists for hours to days, with the magnitude depending on exercise intensity.
Repeated exposure to high-intensity exercise stimulates mitochondrial biogenesis and upregulates key insulin signaling proteins (e.g., IRS-1, PI3K) in the muscle, improving basal glucose tolerance.
These cumulative adaptations reduce insulin resistance and preserve pancreatic beta-cell function, thereby lowering the risk of type 2 diabetes.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review and Meta-Analysis of the Comparative Effectiveness of Vigorous vs Moderate Physical Activity on Type 2 Diabetes Risk
A comprehensive search of databases for prospective cohort studies and RCTs that report associations of both vigorous and moderate physical activity with diabetes incidence, using standardized MET-minutes or similar metrics, and meta-analyze the dose-response curves to derive the equivalent minutes.
Randomized Controlled Trial Comparing Vigorous vs Moderate Exercise for Diabetes Risk Reduction
Adults at high risk for type 2 diabetes randomly assigned to either vigorous exercise program (e.g., high-intensity interval training) or moderate exercise program (e.g., brisk walking) matched for total energy expenditure or time, followed for several years with diabetes incidence as outcome.
Prospective Cohort Study of Physical Activity Intensity and Type 2 Diabetes Incidence
A large cohort (e.g., 100,000+ adults) with baseline assessment of physical activity intensity via validated questionnaires, followed for 10+ years to capture incident diabetes cases, using statistical models (e.g., Cox regression) to estimate hazard ratios per MET-minute and then derive equivalence.
Cross-Sectional Study of Physical Activity Intensity and Diabetes Prevalence
A population-based sample with assessment of physical activity intensity and diabetes status, analyzing the odds ratios for diabetes across different activity levels.
