I have run both hot and cold on the whole Take Off thing. After a lot of reflection, I decided that they can be a great tool, and they can also be overdone. If you are feeling that your body is on the verge of going into starvation mode (which for me I start feeling cold and hungry all the time, which is a bad, bad sign) then doing a take off is a bad idea.
If you have had a little "break" in following the plan, a Take Off can be a really great refocusing tool. As long as you don't gleefully go off plan with the oh well, I'll just do a take off later. That is a dangerous game to play, since it is impossible to make up for a large slip with just two days...
