Hot Rox really is a good thermo though.
The rest are easily replaceable.
I did this diet a few weeks ago, i got through about a week and a half, of the original no food only shakes version. And I decided to cheat a bit one weekend and couldnt stand the thought of going back.
Crazy results though, i lost over 10 lbs in rougly a week and some change. Most of which is already back due to my binging, but im still down 3-4 lbs after eating KFC quality meals for awhile. So it deff works.
But unless you REALLY need to lose weight fast, im not sure i can recommend it. Its just so brutally painfull every single day, it never gets easier. And like mentioned above the shakes make you want to throw up after a few days of nothing but.
