I get what your saying BUT I've just recovered from a broken jaw. While I was recovering I didn't eat anything for about 3/4 weeks, just milkshakes and soup. I lost a stone which obviously isn't cool but I didn't feel all that bad. ALSO I've seen a body shock, or something similar, which featured a guy that could only eat cheese.... he looked reasonably healthy on the outside and didn't complain about any physical problems SOoooO I'm not so sure about it all
