Description

Summary

This study is being completed to compare two dietary approaches for participants with type 2 diabetes. This research will test whether a very low-carbohydrate or a plate-method diet better improves outcomes for blood glucose control and body composition for patients with type 2 diabetes that follow one of these approaches for 12 months.

Participants that meet screening and eligibility will be randomized to one of the two diets. In addition to the diet, study specific visits and assessments will be performed at various timepoints.

Eligibility

You can join if…

Open to people ages 21 years and up

  • diagnosis of type 2 diabetes, with current HbA1c > 6.5% and < 12% (self-reported and then measured at screening)
  • ability to speak English (this is a group-based intervention)
  • ability to engage in light physical activity
  • willingness to be randomized to either type of diet

You CAN'T join if...

  • unable to provide informed consent
  • substance abuse, mental health, cognitive, or medical condition that would, in the opinion of the investigators, make it difficult for the individual to take part in the intervention or may alter key outcomes or require important diet modifications
  • pregnant or planning to become pregnant in the next 12 months, or currently breastfeeding (pregnancy and breastfeeding require modifications to the intervention's dietary approaches)
  • current use of weight loss medications (this is likely to alter weight outcomes and may alter other measures)
  • history of weight loss (bariatric) surgery or plans for bariatric surgery in the next year
  • currently enrolled in a weight loss program or have unalterable plans to enroll in one of these programs in the next year
  • vegan or vegetarian
  • unwilling or unable to participate in study measurements and group classes
  • current use of systemic steroids or immunomodulators (self-reported in screening survey; oral or IV systemic steroids excluded. Injected steroids may be permitted depending on frequency and timing of injections with regard to lab assessments (minimum of 2 weeks between injection and blood tests))
  • weight above 400 pounds (weight limit for dual-energy X-ray absorptiometry (DEXA) scans)
  • history of multiple or recent (within the last four years) kidney stones
  • currently following a very low-carbohydrate diet
