Hi Sealy - great that you've started a diary, and you can tell us as much about your daily life here as you wish... menus are best in the menu thread (or do both perhaps) and then people can benefit from seeing what you're eating!
For day 1 your menu is perfect, and I see no errors... I do see two x chicken breasts, mind, and while that's purrrfect, after a few weeks you'll be sick of the sight of chicken so perhaps good to seek some variety in the early days...
Salmon I adore. Why not serve with a few prawns... if you're hungry, have something else too. You shouldn't be hungry on this diet, and if ever you are to be, it's at the outset so feel free to eat as much protein as you need to quell any hunger.
And drink plenty of water... and remember some vitamins too...
good luck!
