I did it once, with a leader who was everything their leaders aren't supposed be, critical and harsh and totally non-supportive. All foods are given points, which are the same as the diabetic diet units, from what I've read. So, for instance, a medium size apple might be one point, a small baked
potato three. I'm making these up. Then they are divided up into groups. So you get so many points per day for fruit, so many for vegetables, so many for starches, so many for meat. You can mix them up, but at the end of the day you've had a nice, balanced set of meals, even if you did all your fruits at once.
