Type 2 & other diabetes

A six-month low-carbohydrate diet high in fat does not adversely affect endothelial function or markers of low-grade inflammation in patients with type 2 diabetes: an open-label randomized controlled trial

Cardiovasc DiabetolPublished Randomised controlled trial

Authors' conclusion

A LCD high in fat for six months does not adversely affect endothelial function or selected markers of low-grade inflammation, which suggests that this nutritional approach does not increase the risk of cardiovascular disease.

Study context

Population
Patients with T2D64 assessed at 6 months
Participants
71 patients
Comparison
Non-calorie-restricted low-carbohydrate diet (LCD) high in fat vs control diet for 6 months
Primary endpoint
Endothelial function (brachial FMD and NID by US) and markers of low-grade inflammation (plasma IL-6, serum hsCRP)
Follow-up
6 months
Methodological detailsopen-label, randomized 2:1
  • Open-label
  • Randomized 2:1

Primary result

As reported in the abstract

  • FMD and NID unaltered in both groups after 6 months
  • Lack of changes in FMD and NID with LCD persisted after adjustment for cardiovascular risk factors
  • LCD vs Control diet: P = 0.34
  • LCD vs Control diet: P = 0.53
