First off congrats for the 10 days of being good. Sure the weightloss wasn't as hoped but your at least on track behaviour wise which is a huge step. Additionally I think your on the right track with your calorie count and for using calorie king. Theres 101 different types of diets out there and the one thing they all have in common is recording your food intake - so well done.
As for the lack of loss - I think you hit the nail on the head when you mentioned salt. I'm not a subscriber to the restrictive carbs diet, I think its all about energy in, energy out so I won't blame your carb intake but too much salt in your diet can lead to changes in your water retainment. The handy thing is that Calorie King will happily keep track of your salt intake if you ask it to (set nutritional targets, enter in rda which I think is around 1800mg in AU, the US is 2400mg, the UK is 1600mg). That will at least let you be aware of the salt your consuming.
So - rather than salt how about you play around with the herb and spices section of the supermarket. With most spices costing about $2.40 each you could try a new one each week and it wouldn't blow your budget. Paprika is one that springs to mind. For the fish how about lemongrass and lemon ?. For chickenbreast chop up an apricot, add half a teaspoon of jam to stick it together and stuff it inside the breast before steaming and sprinkle with fresh parsley - you won't need salt. With dieting it all about thinking outside the box to get the flavours as unfortuantly most of the flavours we are accustomed to come from fat, sugar and salt.
However, there are dozens of things that can result in small weight gains, certain times of the month, (presuming you are female here, if not - Mr Snowflake my apologies), changes in diet, muscle changes and sometimes just that this week isn't your week.
Keep exercising, regular rather than crazy bursts will help with salt and fluid retention - just don't loose heart, you'll get there
