group attended meetings at baseline

group attended meetings at baseline, 1 mo, and 2 mo, and received their dietary information by e-mail, which included a weekly lesson plan covering the same topics addressed in the group sessions as well as an e-mail message providing an overview of the lesson information. Previous research studies have used this method of providing weekly e-mail lessons for a weight loss intervention [16,
17]. In summary, the omni group allowed for the examination of what would occur via minimal intervention with no recommendation to limit food groups (i.e., usual diet).
Although only vegan diets require supplementary vitamin B12 [1], to control for supplement intake across groups, all participants were required to purchase and take a multivitamin or other form of vitamin B12 daily. After the 2-mo main intervention was completed, all participants (including the omni group) were offered monthly meetings to assist with dietary maintenance. Participants were also provided with a private Facebook group for their diet group after the 2-mo mark to provide social support in between monthly meetings (joining was optional). After the 2-mo intensive intervention phase, participants were encouraged to continue following their assigned diet and meet with their diet group each month. Participants were told they could make alterations to the diet if they needed to but were encouraged to maintain their dietary changes. Par- ticipants received handouts and recipes related to the session topic for every meeting during the 6-mo study. Topic sessions for all the group meetings were informed by the Diabetes Prevention Program [18] and were grounded in social cognitive theory [19]. Each class included food samples or a cooking demon- stration. All group sessions covered identical topics among the five groups with the only difference being the type of diet discussed. The first eight topic sessions for all groups were as follow:

1. Overview of assigned diet
2. Grocery shopping tips
3. Meal planning and dining out
4. Recipe modification
5. Grocery store tour
6. Problem solving: handling holidays and family pressures
7. Dealing with weight plateaus and the slippery slope
8. Ways to stay motivated.

Participants met with only their assigned diet group, which corresponded to a day of the week. Dietary adherence was measured as the absence of any pro- scribed foods from the dietary recalls (e.g., absence of meat, dairy, and eggs from
vegan participants’ food records). Participants in the omni group were considered adherent if their percent energy from fat was

40%. This method of assessing dietary adherence has been used in previous studies [3,20].
