@roarke Although you’re 55, you don’t say your current weight or how tall you are - and your age has little to do with your metabolism - especially since you said you are not menopausal or post-menopausal. You are still producing estrogen which assists in weight loss.
Unless you are under 5’0”, those calories are not what you should consume, especially if you are staying you have 30 pounds to lose. Taking exercise off the table because while it may seem like you are doing extensive amounts, it’s really not going to affect your loss that much. To take off 1 a pound a week, you need to be in a deficit of 7,000 calories a week (1,000 a day). The goal to losing weight is to lose weight on as MANY calories as possible, not as little. What is your TDEE? Have you calculated it?
Going to go on a limb and say this…(I’m making assumptions here) If I were setting your calories and macros, I would have you at 1600-1700 a day (11,200 - 11,900 a week) and put your protein target at 125 grams. 50 grams of fat and 160 grams of carbs (this is 1600 calories a day), for 1700 your carbs would bump to 185. Then be super diligent about weighing and measuring your food and logging it in a tracker. Take personal measurements and weight yourself 3-4 times a week, if not everyday.
This should give you some satisfaction. Hope it helps. If you need more help, reach out. I’m a Personal Trainer and Nutrition Coach so I’m happy to help.
