I wouldn't go below 1700 calories protein burns more calories than carbs or fat cardio only burns calories while u doing it, resistive and weight training damages your muscle tissue so after working out you still burning calories. Also building muscle u burn more calories during the day
I'm 56 just lost 30 lbs doing 1800 to 1900 calories lifting weights 4 to5 Times a week 30 to 40 minutes no more than 20 minutes cardio
I'm 5ft 9 inches I'm now doing2400 calories working on bulking up a little up to 128 going for 135 than c how I look and feed trying to stay 12% body any higher it's really hard to have abs
No that is not the right thing to do. If i were you i would go try to stay arround 20% beneath your daily need. You can go some lower on rest days. But eating really low and calories AND burn all those kcals at the same time doesnt give you the results you want.
