Urgent refeed advice please!

[Rose]

Hi everyone.I am based in New Zealand. I have lost 19 kgs on Cohen's and am only a kg away from my goal weight. Yay!! However this last kg is proving to be so so stubborn and I am really struggling to get rid of it. I am hungry as hell all the time and have a very bad lower backache. Is this normal? Has anyone experienced this? I have my refeed but not sure if I should start it as I am due to fly to the United States and Canada with my family on a holiday for 4 weeks tomorrow. I was thinking perhaps I could make a modest increase in my protein and veggies during the holiday so I could cope with the energy needs on the move and then when I return to NZ I go back on my diet again for another 3-4 weeks or so as required and then start the refeed. I would not be able to weigh food portions while on holiday so was going to just estimate the portion sizes. Does this make sense at all? Or would you please have any other ideas that could be of help? Any tips/advice would be gratefully received. Have a very merry Christmas, everyone!! Rose
