Enough protein?

Increase your fats and oils: you need them for

• hormone and gene regulation,
• brain function, and
• absorption of fat soluble vitamins.

Enough protein but not optimal if you are trying to build lean mass.

1200 might be fine if you are sedentary, at those weights, but if you exercise you would want to eat some calories back. (This is assuming 115 is a healthy goal weight and 136 is probably already a healthy weight or close to it, and that you are not already quite lean/aiming for a weight below a healthy BMI, in which case it's a bad idea, obviously.)

A good way to estimate protein for maintaining muscle is to aim for around .65 to .85 g of a healthy goal weight or around .8-1 g per lb of lean mass. If you would be about 20% bodyfat (quite lean for a woman) at 115, your LBM is around 92, so that would give you a range of 74 to 92 g, as a minimum recommendation. Assuming both 115 and 136 are healthy weights, the broader range based on weight would be 75 g to 115 g.

So 75 g is fine (certainly for health), but toward the low end of the range for maintaining muscle, and at 1200 calories more protein can help because it's satiating too. I'd probably raise it to around 90 g. Your fat number is 25% of calories, which is reasonable, but you are on low calories, so I'd probably raise that too (but I like higher fat in general). However, if you are feeling good on it, there's nothing wrong with it. If it's hard to meet those macros without going over fat, I'd just raise fat, though. Carbs vs. fat is really a personal preference once the protein is sufficient (and assuming you aren't crazy low on fat, which you are not).

I personally would up the calories, I don't think 1200 is enough for the vast majority of people as a lot of the time their BMR (minimum required for the body to function in a basic state) is higher than that.

The protein seems fine though, my goal is 77g and 2050 cals and I have no issue with maintaining muscle while losing or making strength gains. Your fat seems a little low in terms of grams, but on 1200 calories it's a reasonable %.
