Everyone's resting metabolic rate is different. 2400 may sound low to some, while it may sound high to others. Everyone is different. As far as the advice above, I don't think you need to lower your carbs just yet. I feel the same way when my carbs are low, my performance sucks.
What I would recommend doing is to take a short break from dieting, or add a refeed meal/day once every two to three weeks. It sounds like you've been in a deficit for a while, and your body is fighting you. I think a carb refeed would be a good way to keep the scale moving - one step backward, two steps forward.
For a refeed day I would lower fats to about 40-50g, and bump carbs up about 70-80g for starters. This is how I go about refeeds personally, but others will have different opinions. Having a refeed day every few weeks always helps when I plateau. The extra carbs help with gym performance and can increase leptin levels to reduce your hunger and keep the weight loss coming.
How's your training? Are you doing any cardio?
