In a situation like yours, I would want to know my metabolic rate. I'd ask for a number. The rest of us can rely on general guidelines based on height, weight, activity, etc.I eat between 1600 and 1800 calories a day with about 60% carbohydrates, 25% fat, and 15% protein. Yesterday I ate 1876 calories and 50% carbs, 35% fat, and 15% protein. I know that I estimated towards the higher side when I entered the food into FitDay yesterday but still that is a lot. I think I need to cut down on the butter to once a day. I guess I did eat a lot yesterday.
ETA: I found an interesting tib-bit on a thyroid website: I have to subtract 200 calories from the daily caloric intake someone of my weight would take if I want to maintain my weight. If I wanted to loose weight I should be taking in 1400 calories a day and to maintain my weight about 1600 calories per day. That is an eye opener. It also recommends 30 minutes of physical activity daily if I do not want to get fat. That part is common sense. There is this whole formula I can post if someone is interested.
50% or more from carbs is a bit much. I wouldn't get more than 30-40% from carbs if I were you. Fat should be at around 20%. I'd shoot for (p/c/f) at around 40/40/20 or 50/30/20.
For protein, just eat more of the protein foods you like. Less of the carbs you like, and less fat. Make sure you're emphasising good fats like olive oil, fish oils and flax - I know you like flax.
