I wake to 24oz of water with apple cider vinegar and two cups of coffee.
Four hours later I eat breakfast, same thing every day: Eggs, bagel, about a fifth of a stick of butter smeared on it, Greek yogurt and OJ.
Meal two is usually a big meal of some type of meat and heavy on carbs and fat.
Meal three (on work days) is a pb+j and fruit.
Meal four is about 2oz of hard cheddar, and an apple, and a piece of pizza if I'm hungry.
I've been eating this way for years and turned 50 recently, with my bodyweight slowly dropping over the last 15 years from a powerlifter shaped 230 (probably consuming 6000 or so calories a day back then) or so down to 192-195 nowadays (I'm guessing probably 3500 or so calories now). I'm very active and know I couldn't, and wouldn't eat this way if my activity level declined.
