Your starting weight and goal weight are almost identical to mine, 'cept i started almost three weeks ago at 77 kilos. Your food choices look pretty good 'cept how do you manage to eat such a big meal in the morning? I can barely choke down my vitabrits but then my appetite doesn't kick in til around five pm, the problem with working nights.
I think you'll find a good portion of yourfirst weeks weight loss is actually water but thats a good thing because your body is finally managing to get down to a healthy fluid level without the interference of all those extra salts and sugars on board.
Good luck and drink lots of water. I live with a water bottle by my side.
