The primary driver of fat loss is a calorie deficit. You just eat fewer calories than you burn. But this should only be a slight reduction to avoid muscle loss and burnout. Furthermore, I recommend walking as the preferred form of cardio because (1) it is sustainable, (2) it is low in stress, and (3) it doesn't spike hunger. Finally, lifting weights 3 times a week will allow middle-aged and older trainees to fully recover and avoid joint/nervous system fatigue.
Happy training!
P.S. Today's steps.
I got them at the Tobacco Heritage Trail in Victoria, VA.
