I'm afraid I'm not that disciplined in training. Mostly I follow the "European forced diet" model of only eating what I carry home from the store. So if a local (the most common either 3 miles or 6 miles) grocery store has a sale on caffeine free diet Dr. Pepper, I load up my huge pack and carry 55-65 lbs. on the return trip. But mostly I'm making 2-3 shopping trips a week of 20-30 lbs., with milk and juice providing most of the weight. The rest of my training hikes I'll walk to a movie (6 miles) with the trip mostly along a greenway, or up to the Baylands park and hike along the marshes (maybe 9 miles total). When I'm not carrying a load home from the store I'll add extra water, snacks, and a couple of books to my day pack so there's some weight there. So I'll carry anywhere from 15 lbs. to 65 lbs. depending on the circumstances, though only for 3 miles on the return trip at the top weight. Those hikes vary greatly in difficulty. But as I see it, the important thing is to get out and walk frequently, and leaving the car in the driveway nearly all the time is how I achieve that needed frequency.
