50 year old male needs diet/training advice

been working out with a trainer for years now and am in good physical condition for my age.
The main concern is bodyfat. I have been running between 19 and 22% for a while and want to get to sub 15. I was there a few years ago but today it seems much harder
My workouts are 3 days a week. Circuit training alternating a heavy with a light circuit. Cardio in between for 5 days minimum

Diet is fairly clean. Wine 1-2 times a week
No bread. But I do have fruit, almond butter, cocochia bars as snacks.

I have been tracking my diet for appx 1 month and my daily NET caloric intake is around 2000

Any ideas?

topcfp it is known that as one gets older the body fat gets harder to take it off due to its texture changing due to physiological changes that aging brings with it.

Did you make a chart of how your calorie intake is subdivided? Like in 'proteins, carbohydrates and fat'? Perhaps that's where the 'problem' lies?

sort of. I have used an app on the Iphone called lose it. its covers it pretty well although I was pretty much watxhing calories...
How much of a sampling would you like?
DO you have a seugessted breakdown?

I think a breakdown can be best obtained by measuring your height, weight, body fat and compare it with your current diet and calorie intake - and this can be done best by a registered dietitian.

More varieties of cardiopulmonary routines, and more often. I do combinations of swimming, treadmills, ellipticals, stationery bikes, both recumbent and non-recumbent. Watch your overall intake of foods, esp. after 6 P.M.

Try eating smaller portions throughout the day in place of three main meals. Best and most helpful advice, received over 30 yrs. ago. Always do substantial cardio movements/exercises 20-45 mins. before and after weights. This advice came from a former Cin'ti Bengals football player/gym owner and manager and a former Penn State football player who was my general practice physician.
Working well for me. Substitute high fiber content foods for others that you know are full of non complex carbohydrates and go very moderate on the sweets, esp. later in the day.
And, don't worry too much about fat percentages; we all need some of it, to be in actual reality, overall healthier beings.
