I'm not a huge fan of counting calories, but at some level they are useful for quantifying the amount of food you eat. If you regularly create a large deficit of calories, your body will respond accordingly by reducing energy expenditure.
In the worst cases, I've seen (particularly women) eating as few as 800 calories per day and still gaining fat. Not good.
This pattern is called euthyroid sick syndrome, and not eating enough food is not the only thing that can cause it.
Keep a food diary for three days. Life is too short to log food for any longer than this; three days is enough. My favourite app for counting calories, macro and micro nutrients is Cronometer. Enter in a rough estimate of your energy expenditure from movement. For me, this means the energy expenditure from the power meter on my bike in kilojoules. If calories out is hundreds of calories less than calories in, then you may have a problem that needs investigating.
I'm not completely sure. Our sense of hunger should match energy demands. I will speculate and suggest some reasons why I think this might happen:
Now over to you. How many calories per day are you eating? Are you still headed towards a fat-loss goal?
