Our leader talked about the setpoints last week. One of the things she talked about was the counting setpoints for more than one item in a specific group. For example, if you wanted to eat fruit - pick ONE fruit because you will be counting the setpoints for each type of fruit. Let's say there was a fruit salad made with apples, grapes, melon and bananas -- you'd have to count the setpoint for each type of fruit -- (four fruits x the setpoint value). If you just have a serving of melon, you'd count the setpoint only for that one item.
Also, let's say you order steak at a restaurant and count the setpoints but you don't finish all of your steak. You still count the entire value of the setpoint. If you eat the leftovers the next day, you can either weigh the meat and get the correct point value or you can still use setpoints, but you again count the full setpoint value.
The leader explained that this is why setpoints aren't explained until Week 5 so that new people first get the concept of counting points and all that before introducing setpoints -- since it's sort of another way of counting points, but that you are using more of an "average" value instead of the exact.
