Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
A study investigated the effects of a premeal whey protein shot on daily hyperglycemia in individuals with type 2 diabetes, finding significant reductions in hyperglycemia prevalence.
These findings are clinically significant as they suggest that incorporating a whey protein shot before meals could be an effective strategy for individuals with type 2 diabetes to manage their blood glucose levels. By reducing daily hyperglycemia and increasing euglycemia, this dietary intervention may help improve overall diabetes management and reduce the risk of complications associated with poor glycemic control.
Limited sample size may affect generalizability. Short duration of the study may not capture long-term effects. Unmeasured confounders could influence results.

Whey protein shot reduced daily hyperglycemia prevalence by 8% (p<0.05).
Increased time spent in euglycemia by 9% (~2 hours/day, p<0.05).
Mean 24-hour blood glucose was 0.6 mmol/L lower with whey protein (p<0.05).
