To be honest, if you're not losing, then I would definitely cut out the nuts. Are you hungry in between meals? If you are, then this would suggest that you're not eating enough at meal times. If you have to snack, try having a small piece of cheese instead - this is zero carbs. (But ask yourself - are you snacking out of habit, or are you really hungry? Often dehydration is mistaken for hunger, so try having a drink of water in stead).
And it doesn't look as if you're eating much fat, or drinking quite enough water.
Here's a piece about water from Carblife, a low carbing website that I use:
"The weight loss has stopped what am I doing wrong?
Everyone experiences a slowing down or stopping of weight loss at some point in their diet. Listed below are a few things that may help you understand why and what you can do to get moving again.
Water.
Water is essential to weight loss for those who eat low-carb. The minimum consumed in a day should be
Weight-----Litres
140lbs-----2.5
160lbs-----3.0
180lbs-----3.0
200lbs-----3.5
220lbs-----3.5
240lbs-----4.0
260lbs-----4.5
280lbs-----4.5
300lbs-----5.0
320lbs-----5.5
340lbs-----5.5
360lbs-----6.0
380lbs-----6.5
400lbs-----6.5
High levels of ketones in the blood stream can lead to a reduction in ketone production, therefore being well hydrated could aid in keeping the levels low and ketone production ongoing. Consuming enough water can have many other positive side effects: aids your kidneys with the processing of protein, reduces the retention of water, helps with preventing constipation, and reduces the levels of ketones released by your breath, which in-turn will reduce breath odour."
So you should be drinking at least 3 litres of water.
In terms of fat, I assume you're putting an oil-based dressing on your salads? What kind of meat are you eating? Are you putting butter on your veg/frying your veg in butter? Do you use mayonnaise as well?
Fat is really important.
I hope this helps! But let me know what you think/how this reflects what you're eating.
