Randomized Controlled Trial

Some concerns

Participants were included if; participant-reported diagnosis of T2DM; HbA1c 7–11%; fasting blood glucose (FBG) <240 mg/dL (13.3 mmol/L); BMI 27 to 50 kg/m2; age 18 to 70 years; diabetes management by a non-study physician; stable regimen of all medications for at least 3 months; and willingness to attend weekly Weight Watchers meetings in the community and to use Weight Watchers online tools. Use of any diabetes medications, including insulin, was permitted but was not required.

Participants were excluded if they have type 1 diabetes; active cardiovascular/coronary heart disease; blood pressure >160/110 mm Hg; weight loss >5 kg in the previous 3 months; severe depression within the previous year; use of prescription or over-the-counter weight loss medications within 4 weeks before screening; participation in a weight control program within the prior 3 months; and previous weight loss surgery.

The purpose of the study was to examine the effects on glycemic control and weight loss of a combined Weight Watchers program with coordinated telephone and email consultations with a certified diabetes educator (CDE) compared with usual diabetes nutrition counseling and education.
