1600 cal too low for 38yr old male?

rayfu75

Changed up my numbers this morning. Dropping down to 1600 cal a day with macros set at carbs 30, pro 35 and fats 35. Just curious how I'll feel and how different I'll need to eat to hit these numbers daily. More greens and veggies, less pastas and breads. More fruits for carbs and more lean protein sources. Maybe these aren't high enough numbers? I'm 5'5 currently 185lbs. Any advice or suggestions?
