What do you do now for lunch, assuming you work days?

One option is to make the meal you eat at work your "main meal". Fixed time, do not need to test BG. Testing BG only before "discretionary" meals. The last two weeks of a four week challenge, members are given various options to consider and test what works for them. If your waking fasting BG is high, then skip breakfast, eat your lunch without testing BG. If you eat a big breakfast and lunch at work, you may try skipping dinner. Many options are presented and you decide what works for you based on your BG.
