What the research says
2 studies reviewedSupporting (2)
Cohort StudyHuman2014
Eating a lot of protein, especially from meat, is linked to a slightly higher chance of getting diabetes, but the effect is small and seems stronger for women who are overweight.
High intakes of protein and processed meat associate with increased incidence of type 2 diabetes
Cohort StudyHuman2013
The study found that people who ate more protein were more likely to get diabetes, which supports the claim.

That doesn't mean it's settled — it just means no study has tested the opposite.
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.
